천연소재를 사용하는 인조대리석 조성물 및 그 제조방법 {A scagliola composite and the production method using natural materials}Artificial marble composition using natural materials and its manufacturing method {A scagliola composite and the production method using natural materials}

본 발명은 인조대리석 조성물 및 그 제조방법에 관한 것으로, 특히 자갈, 모래, 황토와 같은 천연소재를 사용하므로써 천연대리석과 유사한 질감을 표현할 수 있도록 하면서도 제조비용은 현저히 절감할 수 있는 인조대리석 조성물 및 그 제조방법에 관한 것이다.The present invention relates to an artificial marble composition and a method for manufacturing the same, and in particular, by using a natural material such as gravel, sand, ocher, artificial marble composition and its cost that can be significantly reduced in manufacturing cost while expressing a texture similar to natural marble It relates to a manufacturing method.

천연대리석은 바닥재 및 벽재등의 마감재로 사용되고 있지만 강도가 약해서 얇고 대형인 제품을 얻을 수 없을 뿐만 아니라 동일한 모양으로 대량 생산하는데 한계가 있으며, 자원도 한정되어 있어 대개 수입하여야 하는 고가의 물품이다.Natural marble is used for finishing materials such as flooring and wall materials, but its strength is weak, so it is not possible to obtain thin and large products, and there is a limit to mass production in the same shape, and the resources are limited.

따라서 천연대리석과 같은 미려한 천연의 질감을 발현하기는 곤란하나 가공성과 시공성이 우수하고 다양한 디자인이 가능할 뿐만 아니라, 대량생산이 가능하고 저렴한 재료에 의해 제조되는 인조대리석이 천연대리석에 비해 가격경쟁력과 작업 시공성등이 우수해 널리 사용되고 있다.Therefore, it is difficult to express beautiful natural textures such as natural marble, but it has excellent processability and workability, and various designs are possible. It is excellent in workability and widely used.

그러나 충진제와 결합제, 첨가제를 재료로 제조되는 인조대리석의 경우도 충진제와 수지의 혼합비율이 거의 40: 60비율로 이루어지고, 상기 충진제로는 수산화 알루미늄(Alumnium trihydrate)을 사용하고, 결합제로는 메칠 메타클레이트(Methyl methacrylate)와 같은 고가의 재료를 사용하므로 여전히 사용자들에게는 부담스러운 가격이 아닐 수 없다.However, in the case of artificial marble made of a filler, a binder, and an additive material, the mixing ratio of the filler and the resin is almost 40:60, and the filler uses aluminum hydroxide (Alumnium trihydrate) and methyl as the binder. The use of expensive materials such as methyl methacrylate is still costly for users.

따라서 본 발명은 종래의 인조대리석보다 가격경쟁력에서 훨씬 앞서는 인조대리석을 사용자들에게 제공하기 위한 것으로, 충진제와 결합제(수지), 첨가제를 혼합하여 제조하는 인조대리석에 있어서 상기 결합제로는 약간의 메칠 메타클레이트를 사용하고, 충진제로는 자갈, 모래, 황토와 같은 천연재료를 사용하되 상기 결합제의 물성을 보완하기 위해 중합조절제와 가교제, 개시제, 자외선 안정제와 같은 첨가제를 첨가하므로써 제조비용은 현저히 줄이면서도 천연소재에 의해 질감표현은 천연대리석과 유사한 매우 유용한 인조대리석을 제공할 수 있는 것이다.Therefore, the present invention is to provide users with artificial marble far ahead of the price competitiveness of conventional artificial marble, in the artificial marble prepared by mixing a filler, a binder (resin), additives, the binder as a little methyl meta The crate is used, and as a filler, natural materials such as gravel, sand, and loess are used. However, by adding additives such as a polymerization regulator, a crosslinking agent, an initiator, and a UV stabilizer to supplement the properties of the binder, the manufacturing cost is significantly reduced. Texture expression by natural materials can provide a very useful artificial marble similar to natural marble.

상기와 같은 목적을 달성하기 위한 본 발명의 구성은 다음과 같다.The configuration of the present invention for achieving the above object is as follows.

본 발명은 종래 충진제로 사용되던 고가의 수산화 알루미늄(Alumnium trihydrate)대신에 천연재료인 자갈, 모래, 황토를 대신 사용하므로써 인조대리석의 생산비용을 현저히 절감시키고 천연대리석의 질감을 최대한 표현할 수 있도록 하는 것을 본 발명의 핵심으로 한다.The present invention by using instead of the expensive aluminum hydroxide (alumnium trihydrate) used as a conventional filler to replace the natural material gravel, sand, ocher to significantly reduce the production cost of artificial marble and to express the texture of natural marble to the maximum It is at the heart of the present invention.

이때 자갈, 모래, 황토를 골고루 사용하는 것은 각 재료의 크기별로 형성하는 층이 다르기 때문이다.The use of gravel, sand, ocher evenly because the layers formed by the size of each material is different.

즉 황토는 미세하므로 가장 윗층에 결합제와 혼합되어 매끈한 표면을 형성하게 되고, 모래는 자갈과 황토의 중간층을 형성하게 되며, 자갈은 바닥층에 형성된다.That is, the ocher is fine, so it is mixed with a binder on the top layer to form a smooth surface, and sand forms an intermediate layer of gravel and ocher, and gravel is formed on the bottom layer.

가장 바람직하기로는 미세한 재질인 황토와 모래만을 사용하는 것이나, 이는 부피가 적어 한 종류만 너무 많이 사용할 수 없는 인조대리석에서 차지하는 양이 적게되고 이는 다시 결합제의 양의 증가를 의미하게 되므로 본 발명의 목적을 달성할 수 없기 때문이다.Most preferably, only the fine material of ocher and sand is used, but this is because the volume of the artificial marble, which is too small to use only one type, is less, which in turn means an increase in the amount of the binder. This can not be achieved.

상기 충진제의 함량은 인조대리석의 중량비에 비해 80~85중량%가 되도록 하는 것이 바람직하며, 상기 충진제의 양을 100으로 할때 자갈은 약 30~45, 모래는 약 55~65정도, 황토는 10~15의 비율로 혼합되도록 하는 것이 바람직하다.The content of the filler is preferably 80 to 85% by weight relative to the weight ratio of artificial marble, when the amount of the filler is 100, gravel is about 30-45, sand is about 55-65, loess is 10 It is desirable to mix at a ratio of ˜15.

이때 충진제의 입자가 너무 클 경우는 결합력이 취약하게 되고 배열층의 조절이 곤란하게 되므로 상기 충진제 중 자갈은 2~5mm의 범위의 것을 사용하여야 하고, 모래는 0.1~05mm, 황토는 0.01mm이하의 것을 사용하여야 한다.In this case, if the particles of the filler is too large, the bonding force becomes weak and it is difficult to control the arrangement layer, so the gravel of the filler should be used in the range of 2 ~ 5mm, sand 0.1 ~ 05mm, ocher less than 0.01mm Should be used.

또한 결합제로 사용되는 메칠 메타클레이트(Methyl methacrylate)는 약간의 점성을 갖는 액체상태의 열가소성 수지로써 인조대리석 제조시 표면을 매끄럽게 하고 충진제들을 홀딩(holding)하기 위한 재료이다.In addition, methyl methacrylate, which is used as a binder, is a liquid thermoplastic resin having a slight viscosity, and is a material for smoothing the surface and holding fillers in the preparation of artificial marble.

이때 메칠 메타클레이트의 함량은 인조대리석의 중량비에 비해 20~35정도의 중량%가 적당하다. 만일 20%이하의 중량%로 혼합될 경우 충진제들을 결합하는능력이 현저히 떨어져 너무 취약하게 되며, 이로이내 인조대리석의 내구성이 나빠지게 된다. 물론 35%이상으로 혼합된 경우는 인조대리석의 제조비용이 높아지는 폐단을 갖게된다.In this case, the content of methyl methacrylate is suitably 20 to 35% by weight compared to the weight ratio of artificial marble. If the mixture is less than 20% by weight, the ability to bind the fillers is significantly lowered, which makes the artificial marble worse. Of course, if the mixture is more than 35%, the cost of manufacturing artificial marble will be increased.

상기 메칠 메타클레이트 시럽(Methyl methacrylate syrup)은 폴리 메칠 메타클레이트 25%를 메칠 메타클레이트 단량체(monomer) 75%에 녹여서 제조한 것이다.The methyl methacrylate syrup is prepared by dissolving 25% polymethyl methacrylate in 75% methyl methacrylate monomer (monomer).

또한 상기 결합제의 양은 종래의 인조대리석 제조시 혼합되는 양에 비하면 현저히 줄어든 것이므로 이로인해 발생할 수 있는 본 발명 인조대리석의 물성을 보완하기 위하여 다음과 같은 첨가제를 혼합하였다.In addition, since the amount of the binder is significantly reduced compared to the amount of conventional artificial marble, the following additives were mixed to compensate for the physical properties of the present invention, which may be caused by this.

즉 결합제의 중합시 중합을 조절하기 위한 중합조절제는 0.03% ~ 0.3%정도 함유시키며, 가교제는 0.02% ~ 0.4%정도, 중합을 유도하기 위한 개시제는 0.01% ~0.1%정도, 인조대리석의 황변현상을 방지하기 위한 자외선 안정제는 0.05% ~ 0.2%정도 함유되도록 한다.That is, the polymerization regulator for controlling the polymerization during the polymerization of the binder contains 0.03% to 0.3%, the crosslinking agent is about 0.02% to 0.4%, the initiator to induce the polymerization is about 0.01% to 0.1%, yellowing of artificial marble Ultraviolet stabilizer to prevent this to be contained in about 0.05% to 0.2%.

상기 중합조절제는 n - 도데실 메르캅탄( n-dodecyl mercaptane)을 사용는 것이 바람직하며, 가교제로는 부틸렌 디메타크릴레이트( Butylene dimethacrylate), 개시제로는 아조비스 이소부틸렌(Azobis isobutyronitrile), 자외선안정제로는 티누빈- 피(Tinuvin-P)를 사용하는 것이 바람직하다.The polymerization regulator is preferably n-dodecyl mercaptane (n-dodecyl mercaptane), a cross-linking agent butylene dimethacrylate (B) butylene dimethacrylate (Azobis isobutyronitrile), an ultraviolet ray It is preferable to use Tinuvin-P as a stabilizer.

본 발명의 제조방법은 다음과 같다.The production method of the present invention is as follows.

상기와 같은 충진제, 결합제 및 첨가제를 혼합하여 일정크기의 인조대리석판넬을 제조하기 위한 형틀에 붓는다. 이때 상하판은 경화유리를 사용하였으며, 연질의 폴리비닐클로라이드( Polyvinyl chloride) 호스를 사용하여 부피의 감소에 따른 영향을 흡수하였다.The filler, binder and additives as described above are mixed and poured into a mold for preparing artificial marble panels of a certain size. At this time, the upper and lower plates were made of hardened glass, and soft polyvinyl chloride hose was used to absorb the effect of the volume reduction.

상기 메칠 메타클레이트 시럽(Methyl methacrylate syrup)은 폴리 메칠 메타클레이트 25%를 메칠 메타클레이트 단량체(monomer) 75%에 녹여서 제조한 것으로, 이를 80℃ 수욕상에서 3~4시간 경화후 115℃에서 1시간 열처리를 하여 잔류 단량체 함량을 중합시키게 된다.The methyl methacrylate syrup is prepared by dissolving 25% polymethyl methacrylate in 75% methyl methacrylate monomer (monomer), which is cured in an 80 ° C. water bath for 3-4 hours and then at 115 ° C. 1 hour heat treatment to polymerize residual monomer content.

이때 수욕상에서 경화시 진동장치를 사용하여 상기 형틀에 미세한 진동을 가하므로써 결합체와 충진체간의 결합이 견고하게 이루어지도록 하고, 결합제 속에서 충진체, 즉 자갈, 모래, 황토순으로 층이 이루어지도록 하였다.At this time, by vibrating the mold in the water bath by applying a vibrating device to make the bond between the binder and the filler is made firmly, the filler in the binder, ie gravel, sand, ocher in order to form a layer. .

이로인해 표면에 황토빛이 나는 천연대리석과 같은 미려한 질감의 인조대리석을 제조할 수 있는 것이다.This makes it possible to manufacture artificial marbles with beautiful textures such as natural marble with ocher color on the surface.

본 발명은 고가인 결합제의 양은 현저히 줄이고, 충진제로는 자갈, 모래, 황토와 같은 천연재료를 사용하므로써 인조대리석 제조비용은 현저히 줄이면서도 천연소재에 의해 질감표현은 천연대리석과 유사한 인조대리석 판넬을 얻을 수 있는 것이다.The present invention is to significantly reduce the amount of expensive binders, by using natural materials such as gravel, sand, ocher as a filler, while significantly reducing the cost of manufacturing artificial marble, the texture expression by natural materials to obtain an artificial marble panel similar to natural marble It can be.

물론 충진제의 색상, 또는 크기, 재질에 따라 다양한 무늬를 얻을 수 있으며,이를 인조대리석 성형시 형틀에 가하는 진동정도에 따라 달리 연출할 수도 있다.Of course, a variety of patterns can be obtained according to the color, size, or material of the filler, and may be produced differently depending on the degree of vibration applied to the mold during artificial marble molding.

무엇보다 종래 고가인 인조대리석보다 시공성도 우수하고 표면의 질감도 매우 우수한 인조대리석을 사용자들에게 저렴하게 공급할 수 있는 효과를 갖는 매우 유용한 발명인 것이다.Above all, it is a very useful invention having the effect of supplying artificial marble with excellent constructability and surface texture which is superior to conventional artificial marble at low cost to users.
