일반적으로 건축물에는 내부 및 외부의 장식 목적으로 인조바위, 동물모양조형물, 인조나무 등등 여러가지 형태의 조형물이 설치되고 있으며, 이러한 조형물의 소재로, 석재, 목재와 같은 천연소재와, 유리섬유강화플라스틱(FRP), 유리섬유강화시멘트(GRC,Glassfiber Reinforced Cement), 스티로폼, 폴리우레탄 등과 같은 화학적 소재가 사용되고 있다. In general, the building is installed with various types of sculptures such as artificial rock, animal-shaped sculptures, artificial trees, etc. for the internal and external decoration purposes, and as such materials, natural materials such as stone, wood, and glass fiber reinforced plastic ( Chemical materials such as FRP), glass fiber reinforced cement (GRC), styrofoam, polyurethane and the like are used.
이중 유리섬유강화플라스틱(FRP), 유리섬유강화시멘트(GRC,Glassfiber Reinforced Cement)는 천연소재에 비하여 저렴하고, 시공이 간편하며, 내구성이 뛰어나고, 방습, 내식성 등의 특성을 가지고 있어 널리 사용되고 있다. Double glass fiber reinforced plastic (FRP) and glass fiber reinforced cement (GRC) are widely used because they are inexpensive, easy to construct, have excellent durability, moisture resistance, and corrosion resistance compared to natural materials.
그러나, 상기 유리섬유강화플라스틱(FRP), 유리섬유강화시멘트(GRC)은 금형을 통해, 조형물을 제작하도록 되어 있어, 금형제작에 필요한 여러가지 도구 및 재료를 준비하는 작업이 필수적으로 거처야 하고, 금형제작에 따른 비용이 증가되는 문제점이 있었다. However, the glass fiber reinforced plastic (FRP) and glass fiber reinforced cement (GRC) is to produce a molding through a mold, the work of preparing a variety of tools and materials necessary for manufacturing the mold must be a must, There was a problem that the cost of the production increases.
또한, 상기 유리섬유강화플라스틱(FRP), 유리섬유강화시멘트(GRC,Glassfiber Reinforced Cement)에 의해 대형 조형물을 제작할 경우, 대형 조형물은 부피가 거대하여 금형을 통해 한번에 성형하기 곤란하므로, 다수개의 금형을 제작하여 조각으로 분리 성형하여야 하며, 이로 인해 제조공정이 매우 복잡해지게 되고, 조각 성형 후 이를 맞추기 위한 작업시간이 많이 소요될 뿐 만 아니라, 조립시 맞춤작업에 곤란성이 있었다. In addition, when manufacturing a large molding by the glass fiber reinforced plastic (FRP), glass fiber reinforced cement (GRC, Glass Fiber Reinforced Cement), large moldings are bulky and difficult to mold at a time through the mold, a plurality of molds It has to be manufactured and separated into pieces, which makes the manufacturing process very complicated, and it takes a lot of work time to fit the pieces after molding, and also has difficulty in fitting during assembly.
또한, 평판 조형물의 경우, 발포 폴리우레탄 또는 스티로폼이 널리 사용되고 있으나, 발포 폴리우레탄과 스티로폼은 상온에서는 절단 가공을 제외하고는 형상 변형을 위한 가공이 곤란하므로, 조형물을 형성하려면 소재를 용융한 후 다양한 형상을 가지는 금형에 충전하여 완제품을 생성하는데, 금형의 제작으로 인해 생산 비용이 많이 들고 생산성이 크게 저하되는 문제점이 있었다. In addition, foamed polyurethane or styrofoam are widely used in flat moldings, but foamed polyurethane and styrofoam are difficult to process for shape deformation except cutting, at room temperature. Filling a mold having a shape to produce a finished product, there is a problem that the production cost is high due to the production of the mold and the productivity is greatly reduced.
또한, 상기와 같은 유리섬유강화시멘트(GRC,Glassfiber Reinforced Cement) 와 유리섬유강화플라스틱(FRP)를 이용하여 만들기 때문에 친환경적이지 못하고 실내 설치 시 유해성분의 용출 및 VOC 성분을 뿜어내기 때문에 인간에게 해로운 제품이 대부분이다. In addition, since it is made of glass fiber reinforced cement (GRC) and glass fiber reinforced plastic (FRP) as described above, it is not environmentally friendly, and it is harmful to humans because it releases harmful components and elutes VOCs when installed indoors. This is mostly.
특히, 유리섬유강화플라스틱(FRP)의 경우 석면파이버의 사용으로 인해 파괴 시 발암물질이 공기 중에 떠다녀 인체에 유해영향을 끼칠 수 있으며 화재 시 유기성 가스를 분출하기 때문에 인체에 좋지 못한 영향을 주는 등 여러가지 문제점이 있었다. In particular, in case of glass fiber reinforced plastic (FRP), asbestos fiber can cause harmful effects on human body due to the floating of carcinogens in the air when it is destroyed. There were various problems.
본 발명은 상기와 같은 목적을 해소하기 위한 것으로, 그 목적은 친환경 탄성바인더와 장섬유 부직포를 이용하여, 유해성분의 용출 및 배출을 방지하고, 인체에 무해하며, 우수한 인장강도를 구비한 친환경 탄성바인더를 이용한 조형물 제조방법을 제공하는 것이다. The present invention is to solve the above object, the purpose of using an environmentally friendly elastic binder and long fiber nonwoven fabric, to prevent the dissolution and discharge of harmful components, harmless to the human body, with an excellent tensile strength environmentally friendly elastic It is to provide a method for producing a sculpture using a binder.

In addition, the present invention is to impregnate the environment-friendly elastic binder into the fibrous nonwoven fabric, and then to mold the molding using it, because it has a tensile strength of about three times higher than the GRC, the thickness of the molding can be reduced, in the form of a strip Since the moldings are molded, the manufacturing process is simple and the production period can be shortened.
또한, 기존에는 인조바위의 경우 2㎡ 이상의 조각조형물을 접합하여 시공함에 있어 무거운 중량으로 인해 인력시공이 불가능하고 크래인등의 대형장비를 동원하여 시공하는 것이 불가피 하였지만 본 발명은 두께를 1/3 정도로 줄일 수 있어, 대형장비 없이 시공이 가능하고 제품의 이동시 가벼운 중량으로 인해 좁은 공간으로 인력으로 이동이 가능하다. In addition, in the case of artificial rock in the past to join the sculpture sculptures of more than 2㎡ It is inevitable to manpower construction due to the heavy weight, and it is inevitable to use large equipment such as crane, but the present invention is about 1/3 thickness Because it can be reduced, it can be installed without large equipment and it can be moved by manpower due to the light weight when moving the product.
또한, 본 발명은 덧붙이기 형식의 다층 겹침에 의해 조형물을 성형하므로, 별도의 금형작업 없이도 신속하게 조형물을 성형할 수 있으며, 불규칙하고 다양한 형상의 곡선창출이 가능하고, 화재의 위험성이 없다. In addition, the present invention, because the molding is molded by the multi-layer overlap of the addition form, it is possible to quickly mold the molding without a separate mold work, irregular and various curves can be created, there is no risk of fire.
또한, 본 발명은 경량골재를 사용하지 않고 무게를 줄여 흡수율이 작고 내구성이 높이며, 탄성과 높은 인장강도를 구비한 탄성바인더를 함침시켜 다층 접합에 의해 조형물을 형성하므로, 완성된 조형물의 크랙발생을 줄일 수 있다. In addition, the present invention by reducing the weight without the use of lightweight aggregate, the absorption rate is small, high durability, and impregnated an elastic binder having elasticity and high tensile strength to form a molded object by the multi-layer bonding, so that the cracks of the finished sculpture Can be reduced.
또한, 본 발명은 대형 조형물에도 쉽게 적용가능할 뿐 만아니라, 성형시간도 매우 짧고 전체적인 조형물의 무게가 가벼워 취급을 용이하게 할 수 있는 등 많은 효과가 있다. In addition, the present invention is not only easily applicable to large moldings, but also has a large effect such that the molding time is very short and the overall weight of the molding can be easily handled.
도 1 은 본 발명에 따른 구성을 보인 블록예시도를 도시한 것으로, 본 발명은 장섬유 부직포에 탄성바인더를 함침시킨 후, 탄성바인더가 함침된 장섬유 부직포를 형틀에 부착 경화시켜 조형물을 형성하도록 되어 있다. Figure 1 shows a block diagram showing the configuration according to the present invention, the present invention after impregnating an elastic binder in a long fiber nonwoven fabric, to form a molding by attaching and curing the long fiber nonwoven fabric impregnated with an elastic binder to the mold It is.
즉, 본 발명은 친환경 액상바인더에 시멘트 무첨가형 무기질 바인더를 첨가 혼합하여 친환경 탄성바인더를 형성하는 혼합단계와, 친환경 탄성바인더에 장섬유 부직포를 함침시키는 함침단계와, 함침된 부직포를 덧붙이기 형식에 의해 형틀에 부착하여 응결시켜 조형물을 형성하는 성형단계를 포함하도록 되어 있다. That is, the present invention is a mixing step of forming an eco-friendly elastic binder by adding and mixing cement-free inorganic binder in an eco-friendly liquid binder, an impregnation step of impregnating a long-fiber nonwoven fabric in an eco-friendly elastic binder, and adding an impregnated nonwoven fabric. It is to include a molding step of forming a sculpture by attaching to the mold by condensation.
또한, 본 발명은 성형된 조형물 다수개를 탄성바인더가 함침된 장섬유 부직포에 의해 연결하여 대형 조형물을 형성하는 대형 조형물 성형단계를 더 포함하도록 되어 있다. In addition, the present invention is to further include a large molding molding step of connecting a plurality of molded moldings by a long fiber nonwoven fabric impregnated with an elastic binder to form a large molding.
상기 혼합단계는 혼합통내에 친환경 액상바인더를 먼저 넣고 이후 시멘트 무첨가형 무기질 바인더를 첨가하여 약 90∼150 초동안 혼합한다. In the mixing step, the eco-friendly liquid binder is first put into the mixing barrel and then the cement-free inorganic binder is added and mixed for about 90 to 150 seconds.
상기 친환경 액상바인더는 수용성 아크릴계 폴리머로써 유리전이온도(Tg)= -60℃ 이상의 것을 사용하고, 점도는 고형분 50% 이상일때 500 cps 이하의 구비한다. 상기와 같은 낮은 유리전이온도(Tg)값을 선택한 것은 폴리머의 특성상 요변성을 높이기 위함이고, 상기 점도는 장섬유 부직포 내로의 침투성을 높이기 위한 것이다. The environmentally friendly liquid binder uses a glass transition temperature (Tg) = -60 ℃ or more as a water-soluble acrylic polymer, the viscosity is provided with less than 500 cps when the solid content is more than 50%. The low glass transition temperature (Tg) value is selected to increase thixotropy in terms of polymer properties, and the viscosity is to increase penetration into a long fiber nonwoven fabric.
상기 무기질 바인더는 속경성 CSA계와 α형 혹은 β형 반수석고를 배합한 시멘트 무첨가형 바인더로써 저탄소 저알카리를 구비하며, 중금속 용출이나 유해성분이 검출되지 않는다.The inorganic binder is a cement-free binder containing a fast-hardening CSA system and an α- or β-type hemihydrate gypsum and has a low carbon low alkali, and heavy metal dissolution and noxious components are not detected.
즉, 상기 무기질 바인더는 속경성 CSA 클링커 65∼88wt%, α형 혹은 β형 반수석고 10∼34wt%, 유동화재 0.1∼2wt%를 포함하도록 되어 있다. That is, the inorganic binder includes 65 to 88 wt% of a fast-hard CSA clinker, 10 to 34 wt% of α- or β-type hemihydrate gypsum, and 0.1 to 2 wt% of a fluidizing agent.
상기 속경성 CSA 클링커는 강도발현과 속경성의 역할을 구비하며, 이와 같은 무기질 바인더는 아래의 [표1]과 같은 특성을 구비하는 것이 바람직하다. The fast-hard CSA clinker has a role of strength expression and fast-hardness, it is preferable that such an inorganic binder has the characteristics shown in Table 1 below.
[표1]Table 1
상기 반수석고는 CaO 60wt% 이상, 압축강도 40㎫ 이상을 구비한다.The hemihydrate gypsum has a CaO of 60 wt% or more and a compressive strength of 40 MPa or more.
상기 유동화재는 나프탈렌계 또는 멜라민계 EH는 폴리카본산계를 첨가하며, 일반 시멘트용 혼화제 KS L 2560에 준하는 것을 첨가한다. The fluidizing agent is naphthalene-based or melamine-based EH is added to the polycarboxylic acid-based, and the addition according to KS L 2560 admixture for general cement.
이때, 상기 친환경 액상바인더와 시멘트 무첨가형 무기질 바인더는 1 : 0.3∼0.5 의 중량비율을 구비한다. 이와 같은 중량비율은 속경성 CSA 클링커와 반수석고 및 액상바인더의 혼합시, 액상바인더내에 함유된 수분에 따른 반수석고의 팽창반응을 억제하기 위한 것으로, 반수석고의 팽창반응이 일어날 경우, 완성된 조형물에 파괴현상이 발생되므로, 적정비율로 배합하여야 한다. At this time, the eco-friendly liquid binder and cement-free inorganic binder has a weight ratio of 1: 0.3 to 0.5. This weight ratio is to suppress the expansion reaction of the hemihydrate gypsum due to the moisture contained in the liquid binder when mixing the fast-hard CSA clinker, hemihydrate gypsum and liquid binder, when the expansion reaction of the hemihydrate gypsum occurs, Fracture phenomenon occurs in the process, so it should be mixed in proper ratio.
또한, 상기 액상바인더와 무기질 바인더는 균일한 혼합을 위하여 약 2분동안 혼합하는 것이 바람직하고, 1 : 0.4 의 중량비율로 혼합하는 것이 바람직하다. 이때의 액상바인더와 무기질 바인더의 혼합은 균일성을 유지하면 되므로, 그 혼합속도에 대해서는 특별히 한정할 필요성은 없다. In addition, the liquid binder and the inorganic binder are preferably mixed for about 2 minutes for uniform mixing, and preferably mixed at a weight ratio of 1: 0.4. Since the mixing of the liquid binder and the inorganic binder at this time only needs to maintain uniformity, the mixing speed is not particularly limited.
상기 장섬유 부직포는 장섬유(FILAMENT)가 단일연속공정에 의해 시트로 형성된 폴리에스터 장섬유 부직포로, 이와 같은 장섬유 부직포는 인장, 인열 강도가 높고, 내마모성이 좋으며, 섬유간 지지력이 탁월하여 장기간 설치하여도 변형 및 물성의 변화가 거의 없다. The long fiber nonwoven fabric is a polyester long fiber nonwoven fabric in which the long fibers (FILAMENT) are formed into a sheet by a single continuous process, and the long fiber nonwoven fabric has a high tensile strength, tear strength, good abrasion resistance, and excellent inter-fiber support. Even if installed, there is almost no deformation and physical property change.
또한, 상기 장섬유 부직포는 각종 합성섬유중 내후성, 내약품성, 내열성(융점:250℃) 등이 가장 우수한 폴리에스터 100%로 구성되어 외부 노출지역, 지하의 어려운 조건하에서도 약해짐이 없이 우수한 기능을 장기간 유지된다. In addition, the long-fiber nonwoven fabric is composed of 100% polyester, the most excellent weather resistance, chemical resistance, heat resistance (melting point: 250 ℃) of various synthetic fibers, excellent function without weakening even under difficult conditions in the external exposure area, underground It is maintained for a long time.
또한, 상기 장섬유 부직포는 폴리에스터 필라멘트가 연속적으로 적층된 구조를 유지하여 수직, 수평 방향으로 우수한 투수성능을 가지고 있어 뛰어난 흡수효과와 미세한 공극을 유지하여 무기바인더와 부착이 뛰어나고 탄성바인더와 거동을 같이하여 요변성을 갖는 조형물을 만들 수 있다.In addition, the long-fiber nonwoven fabric has a structure in which polyester filaments are continuously stacked to have excellent permeability in the vertical and horizontal directions, thereby maintaining excellent absorption effect and fine air gap, and excellent adhesion with inorganic binder, elastic binder and behavior In this way, a sculpture having thixotropic properties can be produced.
상기와 같은 장섬유 부직포는 아래의 [표2]와 같은 물성을 구비한다. The long fiber nonwoven fabric as described above has physical properties as shown in Table 2 below.
[표2][Table 2]
상기 함침단계는 장섬유 부직포를 소정크기로 절단 또는 띠형상으로 절단하고, 이를 탄성바인더에 넣어, 탄성바인더를 함침시킨다. 이때, 장섬유 부직포는 약 90∼150 초동안 함침시키며, 바람직하게는 약 120초 동안 함침시킨다. 이와 같은 함침시간은 장섬유 부직포에 탄성바인더가 충분히 함침되고, 조형물의 성형시 필요한 성형시간을 부여하게 된다. In the impregnation step, the long fiber nonwoven fabric is cut into a predetermined size or cut into a band shape, and the elastic fiber is impregnated into the elastic binder. At this time, the long fiber nonwoven fabric is impregnated for about 90 to 150 seconds, preferably about 120 seconds. Such impregnation time impregnates the long fiber nonwoven fabric with the elastic binder sufficiently, and imparts a molding time necessary for molding the molded product.
상기 성형단계는 형틀에 탄성바인더가 함침된 장섬유 부직포를 다층으로 겹쳐서 덧붙여 경화시키고, 이를 형틀로 부터 분리하여 조형물을 형성한다. 이때, 상기 덧붙이는 장섬유 부직포는 함치된 친환경 탄성바인더가 응결되기 전(30분)에 반드시 후속 작업 즉, 덧붙이는 작업이 들어가야 하며, 그렇지 않을 경우 부착강도가 떨어져 층 분리현상 혹은 박리 현상이 일어날 수 있다. 또한, 경화는 탄성바인더가 응결되는 시간이므로, 특별히 시간을 한정할 필요는 없다.In the forming step, a long fiber nonwoven fabric impregnated with an elastic binder is overlapped with a multilayer and cured, and then separated from the mold to form a molding. In this case, the additional long fiber nonwoven fabric must have a subsequent operation, that is, an addition operation before the condensed eco-friendly elastic binder is condensed (30 minutes), otherwise the adhesion strength is reduced and a layer separation or peeling phenomenon may occur.
