Description

Wooden stone decks using composite materials and their manufacturing methods

The present invention relates to a wood-type stone deck using a composite material and a method for manufacturing the same, and more particularly, to at least one of calcium carbonate (stone), silica sand, masato, calcite, berth, limestone, chalk, ice tin, and shells The ratio of the mixed material mixed with fiberglass powder and the composite material mixed with synthetic resin is adjusted and supplied to the lower and upper layers, and the fiberglass is extruded between the lower and upper layers and twisted reinforcing cores are inserted at regular intervals to create a vibrator. In the process of forming solid wood-type stone decks, stair boards, and building interior/exterior materials by heat treatment after flat molding with a (vibrator), coupling grooves are formed at both ends to the upper side of the part fixed to each pipe with fixing screws. It relates to a wood-type stone deck using a composite material that is combined to hide the coupling groove on the opposite side and a manufacturing method thereof.

Along with the development of plywood manufacturing technology, it is a well-known fact that the utilization of raw wood is increased and plywood with excellent physical properties is being provided in large numbers. The surface is decorated with, and the surface is coated with resin paint to give resistance to water resistance and scratches.

As an example of manufacturing this type of indoor floor covering, there is a method of manufacturing a floor board by attaching a veneer veneer to a composite upper surface with a urea resin, but it causes an increase in manufacturing cost and has a disadvantage in that water resistance and heat resistance are very weak.

As another example, in the case of a floorboard manufactured by pressing and bonding melamine resin impregnated paper (LPM) to the upper surface of a heavy fiber board (MDF) at high temperature and high pressure, it has the advantage of reducing manufacturing cost, but has poor water resistance and heat resistance. There are downsides.

In addition, plywood or heavy-duty fiberboard used as a base material is usually processed in a dry state, but in the environment where it is installed and used on the internal floor of a building, changes in indoor temperature and humidity occur due to seasonal changes such as summer and winter. Internal stress caused by shrinkage and swelling causes phenomena such as lifting or spreading of the connection part, and it is difficult to maintain the initial bonding condition due to chemical deterioration, resulting in weak dimensional stability and water resistance. will do In addition, there is a preservative wood floor board, but there is a drawback that it is difficult to use because toxic chemicals are added during the preservative process and are harmful to the human body.

Unlike this, by using HDF (Hight Density Finderboard) laminated flooring, click processing and suspension construction are possible and surface strength can be strong, but natural veneer is not used, so natural texture is reduced and water resistance is reduced. It is vulnerable to, and the weight is also heavy.

Utility model registration No. 0399316 to solve these problems discloses an ondol floor based on a wood fiber (wood particle)-polypropylene fiber composite material.

In the prior art, WPC (Wood Fiber Poiypropylene Hiber Composite Panel) is used as the main substrate for ondol flooring in the prior art to compensate for water resistance, which is the biggest disadvantage of laminate flooring, and to compensate for the impact resistance of plywood flooring, Although a flooring material capable of producing a natural texture effect is provided, there are problems in that it is very difficult to obtain a flooring material having a low scratch resistance and a high gloss surface due to the nature of the surface sheet.

In addition, in the case of conventional plywood flooring, veneer is attached on top of the plywood, and then coloring and coating are performed by a roll coater. However, in the case of coloring, it goes through a coloring process by a roll coater, so the disadvantage of not being able to keep the grain (pattern) of wood, which is the advantage of veneer, and the surface hardness, surface scratch resistance, abrasion resistance and durability are located Urethane However, there is a problem in that, since the strength is strong, the flexibility is rather deteriorated and easily broken.

Unlike this, among several developed technologies for reinforcing surface strength, the WPC (Wood Polymer Composite) method is to impregnate wood veneer (veneered wood) with resin to increase strength and hardness, and then finish with lower, middle, and top coats. In some cases, a method of hardening by forcibly injecting resin by pressurizing the wood veneer into the voids and cell layers of the wood in a state where the wood veneer is not attached to the plywood is adopted. There is a problem in that defects such as cracking occur.

In addition, in the case of plywood manufactured by the melamine resin impregnation and overlay press method, when attaching the veneer on the plywood, the veneer impregnated with melamine resin and the overlay containing aluminum oxide (Al2O3) are covered on the upper part of the veneer, and then at high temperature , It has a manufacturing method similar to that of laminated flooring by infiltrating the inside of the veneer with a high-pressure press, but this also has problems in that the economic feasibility of the production process is lowered due to expensive actual costs and cumbersome work methods, and the thin layer on the veneer desired by consumers. Obtaining a surface texture by a coating method is pointed out as a difficult disadvantage.

Patent Registration No. 0978586 (registered on August 23, 2010), previously filed by the present applicant, is a mixture of calcium carbonate and synthetic resin in a weight ratio of 6:4, and 97 to 99.8% by weight of the mixture and A lower layer formed by mixing and stirring 0.2 to 3% by weight of a pigment; an intermediate layer in which fiberglass is formed on the upper side of the lower layer; It consists of an upper layer in which calcium carbonate and synthetic resin are mixed at a weight ratio of 7:3 on the upper side of the middle layer, and 97 to 99.8% by weight of the mixture and 0.2 to 3% by weight of a pigment are mixed and stirred to form an upper layer, which is molded using a press. , There is no shrinkage or expansion, and it provides a product with good water resistance, heat resistance, and durability, but it takes about 30 minutes for press molding, and not only does it consume time for press molding, but also the preparation time for press molding and press molding are completed. There was a problem in that productivity and economy were lowered due to the problem that it took more than 40 minutes during the molding process as a whole because of the time spent separating from the press and the time for demolding.

In addition, Patent Registration No. 1685117 (registered on December 5, 2016) filed by the present applicant contains 97 to 99.8% by weight of a mixture of calcium carbonate, silica sand, and masato and a synthetic resin at a weight ratio of 6:4 and 0.2% by weight of a pigment. A middle layer made of a glass fiber mat is formed on the upper side of the upper layer composed of ~ 3% by weight, and a mixture of calcium carbonate and synthetic resin in a weight ratio of 7: 3 is 97 ~ 99.8% by weight and 0.2 ~ 3% by weight of the pigment. In the flooring material including a lower layer made of, the middle layer is made by supplying a glass fiber mat and then supplying any one of a metal mesh and an iron core coupled to form a cross at a long interval formed, the upper layer and the middle layer, and While molding the lower layer, it was molded by providing vibration for 250 to 350 seconds, respectively.

However, since the upper side of the mold, that is, the plane of the bottom of the lower layer of the product is irregularly formed, a separate post-processing process must be performed to level the floor, so there is a problem of delaying the processing time for post-processing and extending the molding time of the product. When the composite material is not mixed uniformly, various problems such as internal pores are generated when cutting the composite material.

In addition, Patent Registration No. 1809196 (registered on December 8, 2017), previously filed by the present applicant, is that the composite material melt supply step supplies molds in the range of 3 to 15 to the upper side of the mold support of the vibrator, so that the mold holder is A heat treatment step of fixing so as not to move, coating the inside of the mold with a release agent, and forming the lower layer by supplying the mold to a conveyor and molding by heat treatment for 45 to 75 seconds in a heating furnace heated to 30 to 80 ° C. The flooring material was molded through further carrying out.

However, no matter how precise the mold is, molded flooring has a defect in that the floor surface is not constant after being installed in the actual field because the height produced is not constant, and after installing molded flooring, the surface is coated with resin, Since the normal frictional force is not provided until the coated part such as resin disappears, the risk of safety accidents is exposed, and the fixing screw penetrates from the upper side to be exposed to the irregularities of the flooring and is fixed to the square tube installed at the bottom. Exposure to it caused damage to the aesthetics.
