Description

{Manufacturing method of wallpaper with improved surface embossing}

The present invention relates to a method for manufacturing a wallpaper, and to pass through between male and female molds to form a convex embossed shape on both the front and back sides. After embedding, the surface embossing shape is not depressed and added to the formed embossing surface. The present invention relates to a method of manufacturing a wallpaper with improved surface embossing, by additionally forming an embossed shape to improve the aesthetic sense of three-dimensional effect.

Currently, the general wallpaper market is divided into silk wallpaper and laminated wallpaper.

The silk wallpaper expresses embossing only on the surface to which the pvc sol is applied by applying a pvc sol to the entire surface of the base paper, blowing through the heat chamber, and pressing it with an iron roller.

Since the silk wallpaper is embossed only on the surface to which the pvc sol is applied, the embossed three-dimensional effect is preserved as it is before construction, but the product manufacturing cost and labor cost are difficult due to the high cost of product manufacturing and construction.

On the other hand, in using two sheets of paper, the adhesive paper is first applied to one side of the paper and bonded to the other sheet to pass through between the male and female rollers to form convex embossing on both the front and back sides.

At this time, unlike silk, the paper itself cannot emboss only the surface.

Such a paper embossing wallpaper has a lower manufacturing cost than an silk wallpaper and is easy to apply, so the overall cost of coating is advantageous and is generally widely sold.

When embossing is formed on a silk wallpaper In the case of a silk wallpaper, there is no change in the three-dimensional embossing effect before and after construction, but the cost is high, and when burned, black toxic gas is generated. have.

In the case of laminated wallpaper, there is an advantage in silk wallpaper in terms of cost or environmental conditions in forming embossing, but there is a problem in that the three-dimensional effect of surface embossing is significantly reduced compared to before construction after the paper construction.

Specifically, in the process of applying a paste for a certain period of time to prevent creaking after applying a paste during construction, the moisture in the paste penetrates into the embossing paper on the back side, and the embossing sinks about 20 to 30%. After the expansion, the embossing disappears about 20 to 30%.

Therefore, the surface embossing is lost by about 50% after construction compared to before construction, and it is not possible to expect the aesthetic sense of the wallpaper, such as the embossing three-dimensional effect seen in the pre-construction product.

Accordingly, as described in "Eco-friendly water-based foam antibacterial wallpaper by partial application method and its manufacturing method" (Korean Patent Publication No. 10-1927259, Patent Document 1) Attempts have been made to improve lamination embossing, such as passing a mold, but only problems such as seams are raised due to coating treatment during overlapping construction, and it is not very helpful in improving embossing.

KR 10-1927259 (2018.12.04)

The method of manufacturing a wallpaper with improved surface embossing of the present invention is intended to solve the problems occurring in the prior art as described above, and is intended to be able to realize a significantly improved three-dimensional effect more conveniently than a conventional lamination embossed wallpaper.

More specifically, after forming the first emboss on the surface of the base paper using a roller having surface irregularities, the sol composition is applied in a different pattern or shape from the first emboss to form the second emboss, and then the adhesive sol composition is formed as a whole. After application, it is squeezed and transferred to act as a bridge that connects the first and second embos to each other, thereby suppressing the depression of the first embo after the construction of the paper, and allowing the second embo to be preserved, so that it can be preserved on the general lamination embossed wallpaper. It is intended to be able to express embossed three-dimensional impression that is significantly improved.

In order to solve the above problems, a method of manufacturing a wallpaper with improved surface embossing of the present invention includes a printing step of printing such that a specific color and pattern are formed on the surface of the base paper 10 using pulp as a raw material; A first embossing step of forming a first emboss 11 by passing the base paper 10 with a male and female form roller 2 having an uneven surface formed thereon; After preparing the foamed sol composition, after applying the foamed sol composition to the roller (3) having grooves sculpted in a specific pattern shape, cut it with a dockknife device (4) so that the pattern shape remains only in the grooves of the roller. , A composition application step of applying a foaming sol composition to the surface of the base paper 10 by passing the base paper 10 on which the first emboss 11 is formed; A second embossing step of forming a second emboss 20 having a plurality of pores 21 therein by allowing the foam sol composition to foam by passing the base paper 10 coated with the foam sol composition through a drying chamber; After the adhesive sol composition 30 is applied to the copper plate roller 6, the adhesive sol composition ((2) is passed through the base paper 10 on which the second emboss 20 is formed between the pressure roller 7 and the copper plate roller 6 30) a transition step of allowing the inside of the pores 21 of the second embossing 20 and the fibrous tissue of the base paper 10 to be transferred; And a drying step of drying the base paper 10 to which the adhesive sol composition has been transferred through a heat chamber.

In the above configuration, the grooves of the roller 3 provided with the grooves in the composition application step are different from the patterns or shapes of the uneven patterns of the male and female mold rollers 2 used in the first embossing step. The second embossing 20 formed in the second embossing step by applying the foam sol composition in a different pattern or shape from the first embossing 11 has a different pattern or shape from the first embossing 11 It is characterized by.

In addition, the foamed sol composition, acrylic resin solids 25 to 31% by weight, foaming agent 2 to 4% by weight, starch 15 to 25% by weight, kaolin 15 to 25% by weight, glycerin 0.4 to 0.6% by weight, antifoaming agent 0.4 to 0.6% by weight % And residual water.

In addition, the adhesive sol composition is characterized in that it comprises an acrylic resin solid content of 30 to 50% by weight and the remaining amount of water.

In addition, the base paper 10 is a synthetic support paper in which the upper base paper 10a and the lower base paper 10b are laminated, and before the printing step, an adhesive is applied to the surfaces facing the upper base paper 10a and the lower base paper 10b. However, one end of the upper base 10a protrudes a certain distance from one end of the lower base 10b, and the other end of the lower base 10b protrudes a certain distance from the other end of the upper base 10a. Thereby, the lamination step of forming the non-overlapping margin portion 10c of the upper base paper 10a and the lower base paper 10b on both sides of the lamination; proceeds, and the composition application step and the transfer step are the surfaces of the upper base paper 10a. It is characterized by applying a foaming sol composition and an adhesive sol composition, respectively.

According to the present invention, it is possible to realize a significantly improved three-dimensional effect more conveniently than the conventional lamination embossing wallpaper.

More specifically, after forming the first emboss on the surface of the base paper using a roller having surface irregularities, the sol composition is applied in a different pattern or shape from the first emboss to form the second emboss, and then the adhesive sol composition is formed as a whole. After application, it is squeezed and transferred to act as a bridge that connects the first and second embos to each other, thereby suppressing the depression of the first embo after the construction of the paper, and allowing the second embo to be preserved, so that it can be preserved on the general lamination embossed wallpaper. Compared to this, it is possible to express an embossed three-dimensional effect that is significantly improved.

1 is a process schematic diagram showing a method of manufacturing a wallpaper with improved surface embossing of the present invention based on a sheet of paper.
2 is a process schematic diagram showing a method of manufacturing a wallpaper with improved surface embossing of the present invention based on a synthetic paper.
Figure 3 is a perspective view showing the configuration of the margin portion in the present invention.

Hereinafter, a method of manufacturing a wallpaper with improved surface embossing of the present invention will be described in detail through the accompanying drawings.

1. Printing stage

After preparing the base paper 10 using pulp as a raw material, the base paper 10 is passed through the printing apparatus 1 shown in a schematic diagram in FIGS. 1 and 2 so that a specific color and pattern are formed on the surface of the base paper 10. do.

2. The first embossing step

As shown in the schematic diagrams of FIGS. 1 and 2, the first embossing 11 is formed by passing the base paper 10 through the male and female form rollers 2 having irregularities on the surface.

3. Composition application step

After preparing the foamed sol composition, after applying the foamed sol composition to the rollers 3 having grooves sculpted in a specific pattern shape as shown in FIGS. 1 and 2, the pattern shape is cut out by a poison knife device 4 After being left only in the grooves of the roller, the sol composition is applied to the surface of the base paper 10 by passing the base paper 10 on which the first embossing 11 is formed.

At this time, the grooves of the roller 3 provided with the grooves may be configured such that its pattern or shape is the same as the pattern or shape of the unevenness of the male and female frame roller 2 used in the first embossing step.

In this case, the second embossing 20 formed in the second embossing step, which will be described later, is located at the top portion of the unevenness of the first embossing (!1) to strengthen its shape, thereby increasing the height of the top of the unevenness, thereby enhancing the embossing effect. You can maximize it.

The groove 3 of the roller 3 provided with the groove has a pattern or shape different from that of the uneven pattern or shape of the male and female frame roller 2 used in the first embossing step, and thus has a pattern different from the first emboss 11 or The foamed sol composition may be applied in a shape.

In this case, the second emboss 20 formed in the second embossing step to be described later has a different pattern or shape from the first emboss 11.

At this time, a pattern different from the first embossed 11 means a state in which the first embossed 11 is formed in the same shape as the first embossed 11 or excluded from being in the same shape, and the foam composition applied in the entire section on the cross section In addition to the position of the first embo 11 and the position completely different, as well as the position of the foam composition applied in some sections and the first embo 11 overlapped and overlapped with each other in the section including the overlapping position Means

If, when the foamed sol composition is formed on the first embossing 11, that is, having the same shape and pattern, the unevenness of the base 10 after going through the second embossing step, which will be described later, increases in height difference between the top and bottom ends. do.

In this case, when going through the transition step described later, the base between the copper plate roller 6 and the pressure roller 7 receives a lot of pressure from the protrusions of the unevenness, but the grooves of the unevenness receive relatively little pressure. The resulting adhesive sol composition has relatively little transition.

On the other hand, if the application position of the foamed sol composition is staggered with the first embossing 11, the groove depth of the irregularities on the surface of the base 10 that has undergone the second embossing step is relatively small, so that the transition of the adhesive sol composition is better. Will be done.

Specifically, when the following second emboss 20 is formed on the first emboss 11 formed on the base paper 10, when passing between the copper plate roller 6 and the rolling roller 7, the second embo (20) is a relatively stronger pressure in the vertical direction, so a relatively small amount of the adhesive sol composition is located inside the second embo 20, and thus it is difficult to maintain the embo shape using the adhesive sol composition. Is done.

On the other hand, when the first embossing 11 and the second embossing 20 are staggered, when the base paper 10 passes between the copper plate roller 6 and the rolling roller 7, the second embossing 20 is Since relatively less pressure is applied in the vertical direction, a relatively larger amount of the adhesive sol composition is located inside the second embo 20, so that the shape of the embo using the adhesive sol composition becomes smooth.

On the other hand, the foamed sol composition is capable of various sol compositions containing a foaming agent having a foaming function, among them, 25 to 31% by weight of the solid content of acrylic resin, 2 to 4% by weight of the blowing agent, 15 to 25% by weight of starch, and 15 to 25 of kaolin. It is preferably composed of weight%, glycerin 0.4 to 0.6% by weight, antifoaming agent 0.4 to 0.6% by weight, and residual water.

The above-mentioned sol composition is mixed with raw materials and aged at room temperature for 4 to 6 hours, so that the foamed surface becomes smooth after foaming, the viscosity is maintained, and elasticity is improved.

Compared with the above-mentioned composition compared to Patent No. 10-1953282 selected by the inventor of the present application, the content of the blowing agent and starch is increased, and kaolin is newly added.

Kaolin is a porous granule, a cretaceous sedimentary rock layer that contains many planktonic harmful calcium carbonates such as limestone and metamorphic algae. It is said to be.

Accordingly, there is a case used in the conventional wallpaper manufacturing process to obtain anion and far infrared radiation effects.

The inventor of the present application utilizes such kaolin as a raw material for foaming sol composition, and as a result of experimenting several times, when adding a certain amount of kaolin powder when using starch, the foamability is further improved, and the margin part gets wet or damaged in the grass during construction. I noticed this much shrinking.

In addition, when kaolin is added, it is excellent in waterproofing ability after drying, thereby preventing moisture from penetrating the coated surface during construction.

In addition, by adding more foaming agents than in the prior art, the foamability can be improved more than in the prior art.

At this time, if white clay is used among the kaolin, it is possible to realize the wallpaper of the stepped color.

If the kaolin content is less than 15% by weight, the waterproof performance is deteriorated, and if it exceeds 25% by weight, a high viscosity phenomenon in which the sol raw materials are not evenly mixed occurs.

In addition, starch has a high foaming ratio, light weight and excellent adhesion, and white clay blocks water absorption of acrylic resin and starch, hindering moisture absorption during doubling construction, and prevents glued surfaces from sticking together during doubling construction. Will suppress it.

In addition, when the content of the blowing agent in the above-described ratio is less than the lowest value in the range or the starch content is less than the lowest value in the range, the foaming performance deteriorates and the three-dimensional effect is deteriorated, and in the opposite case, the margin part is easily damaged.

4. The second embossing step

The foamed sol composition is passed through a drying chamber so that the foamed sol composition is foamed to have a different pattern or shape from the first embo 11, and a plurality of pores 21 are formed therein. 2 to form the emboss (20).

The second embossing 20 may be formed on the first embossing 11 as described above, but as described above, the second embossing 11 is disposed to be staggered with the pattern of the first embossing 11 and is formed differently from the shape of the first embossing 11. desirable.

5. Transition stage

The transfer step is a very important configuration in the present invention, after applying the adhesive sol composition 30 to the copper plate roller 6, the second embossing 20 is formed between the rolling roller 7 and the copper plate roller 6 The adhesive sol composition 30 is passed through the base paper 10 to be transferred into the pores 21 of the second embossing 20 and into the fibrous tissue of the base paper 10.

1 schematically illustrates this process.

Looking at the lower-right detailed drawing of FIG. 1, the adhesive sol composition applied to the copper plate roller 6 is formed between the pressure roller 7 and the copper plate roller 6 between the narrow gaps of the two rollers when the base paper 10 passes. As pressure is directed toward 10), the inside of the pore 21 of the second embo 20 and the inside of the fibrous tissue of the base paper 10 are transferred as shown in the lower left detailed drawing of FIG. 1.

The composition of the adhesive sol composition for this is possible in various configurations, but is preferably composed of approximately 30 to 50% by weight of the solid content of the acrylic resin and the remaining amount of water.

6. Drying step

The base paper 10 to which the adhesive sol composition is transferred is passed through a heat chamber and dried.

When the drying step is performed, the adhesive sol composition coats the surface of the base paper 10 as shown in the lower left corner of FIG. 1, and the second emboss 20 and the base paper 10 are combined with each other.

That is, the adhesive sol composition 30 serves to suppress the phenomenon in which the first emboss 11 and the second emboss 20 are recessed after the construction of the paper, and strongly bonds the second emboss 20 to the base 10. Roles, such as to increase the durability and tensile strength of the base (10).

On the other hand, the base paper 10 may be composed of a single sheet of about 100 ~ 120g, but as shown in Figure 2, each of the 80 ~ 100g upper base (10a) and the lower base (10b) combined support Can be made of paper.

For this, a lamination step is conducted.

For the laminating step for this, prior to the printing step, as shown in FIG. 2, an adhesive 11d is applied to the surfaces facing the upper base paper 10a and the lower base paper 10b to be coated and then dried to produce a lamination paper. have.

In FIG. 2, when the upper base paper 10a is rolled up and laminated with the lower base paper 10b, the comma-cotta 8 in which the adhesive 10d is stored supplies the adhesive to the roll so as to be laminated with the joint paper 10b. Has become.

At this time, although not shown, it is obvious that the drying chamber is installed between the two rolls facing each other for printing and the printing apparatus 1 so that the adhesive is dried.

In addition, it is preferable to adjust the supply position of the base paper during lamination so that the margins 10c are formed on both left and right sides as indicated by the side cross-section of FIG. 2.

Specifically, one end of the upper base 10a protrudes by a certain distance from one end of the lower base 10b, and the other end of the lower base 10b protrudes by a certain distance from the other end of the upper base 10a. It is preferable that the upper base paper 10a and the lower base paper 10b are formed on both sides of the paper so as to form an unoverlapping margin portion 10c.

At this time, it is preferable to form a margin of about 9 to 11 mm at the time of lamination and then cut to 4 to 6 mm after the foaming process is finished so that a size of about 4 to 5 mm remains.

At this time, it is preferable to apply the foam sol composition and the adhesive sol composition to the surfaces of the upper base paper 10a, respectively, in the above-described composition application step and transition step.

When the blank portion is formed, it is possible to minimize the influence of moisture to be pasted during construction.

In addition, even when the seam is rubbed with a roller or spatula, the collapse of the emboss is minimized, so that a clean seam such as butt construction without a trace is guaranteed.

In addition, in the case of using only one sheet of paper, both sides of the process are cut off at the end of the process to make it fit like a silk wallpaper, or the 3mm edges of both sides are covered with the other wall completely covered by preventing the foaming composition from transferring. It can be constructed.

There was a method of manufacturing embossed wallpaper that was passed between male and female type rollers using one sheet of original paper, but after construction, embossing disappeared without a trace and lack of marketability has led to the past.

According to the manufacturing method of the present invention as described above, even if only a single sheet of paper is used, the embossing preservation state becomes good, so that quality, cost reduction, manufacturing convenience, etc. can be remarkably improved.

Hereinafter, embodiments of the present invention will be described.

A sheet of raw paper made of pulp was prepared as a single sheet, and then printed so that a specific color and pattern were formed on the surface of the base paper, and the first embossing was formed by passing the base paper through a male and female form roller formed with irregularities on the surface.

Subsequently, 28% by weight of the acrylic resin solids, 3% by weight of the blowing agent, 20% by weight of starch, 20% by weight of white clay, 0.5% by weight of glycerin, 0.5% by weight of the antifoaming agent, and the remaining amount of water were prepared to prepare a foaming sol composition.

After preparing a roller with grooves sculpted in a specific pattern shape to have the same shape and pattern as the roller used to form the first embo, apply the prepared foam sol composition, and then cut it with a poison knife device so that the pattern shape is only in the grooves of the roller. After being left behind, the sol composition was applied to the surface of the base paper by passing through the base paper on which the first emboss was formed.

Subsequently, the base paper coated with the foamed sol composition was passed through a drying chamber so that the foamed sol composition was foamed, thereby forming a second emboss having a plurality of pores therein.

Then, an acrylic sol composition was prepared by mixing 40% by weight of the acrylic resin solid content and the remaining amount of water, and then applying the adhesive sol composition to the copper plate roller, passing through the base paper on which the second emboss was formed between the platen roller and the copper plate roller. The adhesive sol composition was allowed to transfer into the pores of the second embo and into the fibrous tissue of the base paper.

Subsequently, the wallpaper of Example 1 was prepared by drying the base paper on which the adhesive sol composition had been transferred through a heat chamber.

Prepared in the same manner as in Example 1, after applying the foamed composition, after preparing the roller with the grooves sculpted in a specific pattern so as to have a different shape and pattern than the roller used to form the first emboss, after applying the prepared foamed sol composition After shaving with a dogknife device so that the pattern is left only in the groove of the roller, the second embo is different in shape and pattern from the first embo by applying the foam sol composition to the surface of the base paper through the base paper on which the first embo is formed. Thus, the wallpaper of Example 2 was prepared.

After preparing two upper and lower base papers using pulp as a raw material, laminating them with an adhesive to prepare a synthetic support paper, and then proceeding in the same manner as in Example 1 to prepare the wallpaper of Example 3.

Prepared in the same manner as in Example 3, but when the upper base and the lower base are laminated, the blank portions protruding by 10 mm on both sides of the left and right sides are formed and then cut by cutting 5 mm on both sides. By doing so, the wallpaper of Example 4 was prepared.

<Preparation of comparative example>

The same procedure as in Example 1 was carried out, but the process was terminated by forming a second emboss to prepare a wallpaper of Comparative Example 1.

In addition, the same procedure as in Comparative Example 1 was performed, but the foam sol composition was used to mix the acrylic resin solid content of 29% by weight, capsule blowing agent of 1.3% by weight, starch of 12% by weight, wood powder of 14% by weight, 3% by weight of sugar, and the remaining amount of water. After preparing the forsol composition, a second embossing was used to prepare a wallpaper of Comparative Example 2.
