본 발명은 자연석 무늬를 갖는 인조석의 제조방법에 관한 것으로서, 보다 구체적으로는 수산화 알루미늄과 불포화 폴리에스테르수지를 일정비율로 혼합, 성형하여 자연석과 극히 유사한 무늬가 외부로 표출되도록한 자연석 무늬를 갖는 인조석의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing artificial stone having a natural stone pattern, and more specifically, artificial stone having a natural stone pattern that is mixed with a certain amount of aluminum hydroxide and unsaturated polyester resin at a certain ratio, and molded so that a pattern very similar to the natural stone is expressed to the outside. It relates to a manufacturing method of.

수산화 알루미늄과 불포화 폴리에스테르수지를 혼합(이하 "인조석" 이라 함)시켜 성형되는 제품은 외부로 표출되는 질감이 부드럽기 때문에 건축용으로 사용되 는 욕실용품인 욕조와 양변기 및 전등갓 등으로 다양하게 이용되고 있다.Products molded by mixing aluminum hydroxide and unsaturated polyester resins (hereinafter referred to as “artificial stones”) are used for baths, toilets, lampshades, etc. .

그러나 이에 부가되는 무늬는 소량의 안료를 배합하거나 또는 특정무늬가 인쇄된 테이프를 접착하는 방법을 채용하고 있으나 이로부터 얻게되는 무늬의 질감이 자연석과는 상당한 차이점이 있다.However, the pattern added to this method is to mix a small amount of pigment or to apply a method of bonding a tape printed with a specific pattern, but the texture of the pattern obtained there is a significant difference from the natural stone.

본 발명은 상기와 같은 문제점을 해결하기 위하여 제안된 것으로서, 본 발명은 외부로 자연석과 극히 유사한 무늬가 표출되도록 하므로서 우수한 미감을 갖는 자연석 무늬를 갖는 인조석의 제조방법을 제공하는데 그 목적이 있는 것이다.The present invention has been proposed in order to solve the above problems, the present invention is to provide a method of manufacturing an artificial stone having a natural stone pattern having an excellent aesthetic by exposing a pattern very similar to the natural stone to the outside.

상기의 목적을 달성하기 위하여 본 발명은 중량비로 수산화 알루미늄 60중량%와 불포화 폴리에스테르수지 40중량%의 비율로 배합하여 무늬형성물을 얻는 제1공정과; 하부몰드의 적정부위에 상기 무늬형성물을 불규칙하게 부착하는 제2공정과; 중량비로 불포화 폴리에스테르수지 98중량%에 수산화 알루미늄2중량%를 혼합하여 얻은 성형물을 하부몰드 주입하는 제3공정과; 하부몰드에 상부몰드를 결합시켜 상기 성형물이 압착되면서 몰드의 형상과 동일한 형상의 제품을 얻는 제4공정과; 상기 하부몰드에서 제품을 탈거하여 열처리와 건조시켜 완성품을 얻는 제5공정으로 제조되는 것이다.In order to achieve the above object, the present invention comprises a first step of blending in a ratio of 60% by weight of aluminum hydroxide and 40% by weight of unsaturated polyester resin in a weight ratio to obtain a patterned product; A second step of irregularly attaching the pattern formation to a proper portion of a lower mold; A third step of injecting a lower mold into a molded product obtained by mixing 2% by weight of aluminum hydroxide with 98% by weight of unsaturated polyester resin in a weight ratio; Combining the upper mold with the lower mold to squeeze the molded product to obtain a product having a shape identical to that of a mold; Removing the product from the lower mold is heat-treated and dried to produce a finished product in a fifth process.

또 상기 무늬형성물은 상부몰드의 표면에 부착하여 성형물이 주입된 하부몰드에 결합하여 무늬를 얻게되는 것이다.     In addition, the patterned product is attached to the surface of the upper mold is bonded to the lower mold in which the molding is injected to obtain a pattern.

이하 본 발명의 제조방법 및 이로부터 얻게되는 특유의 효과등에 대하여 첨 부도면을 이용하여 상세히 설명하면 하기와 같다.Hereinafter, the manufacturing method of the present invention and specific effects obtained therefrom will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 제조공정을 예시한 플로우챠트도로서, 동 도면에 예시되어있는 바와 같이, 본 발명의 제조방법은 불포화 폴리에스테르수지와 수산화 알루미늄을 혼합하는 제1공정(5)과, 상기 제1공정(5)에서 얻은 무늬형성제를 하부몰드에 부착하는 제2공정(10)과, 불포화 폴리에스테르수지와 소량의 수산화 알루미늄을 혼합한 성형물을 하부몰드에 주입하는 제3공정(15)과, 하부몰드에 주입된 성형물을 상부몰드로서 압착하는 제4공정(20)과, 상기 제4공정(20)에서 얻은 제품을 열처리하는 제5공정(25)으로 이루어지는 것이다.1 is a flowchart illustrating a manufacturing process of the present invention. As illustrated in the drawing, the manufacturing method of the present invention comprises a first step (5) of mixing an unsaturated polyester resin and aluminum hydroxide, and A second step (10) of attaching the pattern forming agent obtained in the first step (5) to the lower mold; and a third step (15) of injecting a molded product mixed with an unsaturated polyester resin and a small amount of aluminum hydroxide into the lower mold. And a fourth step 20 for pressing the molded product injected into the lower mold as the upper mold, and a fifth step 25 for heat-treating the product obtained in the fourth step 20.

상기 제1공정(5)에서의 수산화 알루미늄과 불포화 폴리에스테르수지의 혼합은 중량비로 수산화 알루미늄 60중량%, 불포화 폴리에스테르수지 40중량%를 혼합한다.In the mixing of the aluminum hydroxide and the unsaturated polyester resin in the first step (5), 60% by weight of aluminum hydroxide and 40% by weight of the unsaturated polyester resin are mixed.

이러한 비율로 혼합된 무늬형성물은 그 점가가 높아 완성된 제품에서는 흰색으로 선명하게 외부로 표출되어 이 주변을 감싸는 다른 물질과는 확연하게 구분되는 것이다.The patterned product mixed at such a ratio has a high point value, and thus, in the finished product, it is clearly displayed in white and is clearly distinguished from other materials surrounding it.

상기 제1공정(5)에서 얻은 무늬생성물은 특정형상으로 미리 제작된 하부몰드의 표면에 불규칙하게 부착시키게 되는 것이다.The pattern product obtained in the first step (5) is to be irregularly attached to the surface of the lower mold prepared in advance in a specific shape.

이러한 무늬형성물을 부착하는 제2공정(10)에 있어서, 무늬형성물은 그 형상이 특정되지 않은 비정형이고 그 크기도 제품의 특성에 따라 다양하게 조합할 수 있는 것이다.In the second step 10 of attaching such a patterned product, the patterned product is atypical, whose shape is not specified, and its size can be variously combined according to the characteristics of the product.

한편 상기 무늬형성물은 상기와 같이 인위적으로 특정부위에 부착하는 방법과 일정량의 무늬형성물을 하부몰드에 투입한후 상부몰드로 압착하여 몰드의 면을 따라 외측으로 확산되도록하는 방법도 가능한 것이다.Meanwhile, the pattern forming method may be artificially attached to a specific part as described above, and a method of inserting a predetermined amount of pattern forming product into the lower mold and compressing the pattern forming product into the upper mold to spread outwards along the surface of the mold.

이와 같이 하부몰드에 무늬형성물을 부착한후 이에 성형물을 주입하는 제3공정(15)을 행하게 되는 것이다.In this way, the third molding process 15 is performed by attaching the patterned product to the lower mold and then injecting the molded product.

상기 성형물은 중량비로 불포화 폴리에스테르수지98중량%에 소량의 수산화 알루미늄 2중량%를 혼합한 것이다.The molding is a mixture of 98% by weight of unsaturated polyester resin in a weight ratio of 2% by weight of a small amount of aluminum hydroxide.

이와 같이 하부몰드에 무늬형성물의 부착과 성형물의 주입이 완료된 상태에서 하부몰드에 상부몰드를 정합시켜 압착하면 성형물이 외부로 확산되면서 미리 부착되어있는 무늬형성물과 일체로 합일되면서 하부몰드의 형상과 동일한 제품을 얻는 제4공정(20)이 완료되는 것이다.As such, when the upper mold is matched to the lower mold while the pattern molding is attached to the lower mold and the injection of the molding is completed, the molding is diffused to the outside and united with the previously attached pattern molding to form the shape of the lower mold. The fourth step 20 of obtaining the same product is completed.

이렇게 성형된 제품은 하부몰드에서 탈거하여 고열의 로에 넣어 열처리하는 제5공정(25)을 거치므로서 완성품을 얻게 되는 것이다.The molded product is removed from the lower mold and put into a high-temperature furnace to undergo a fifth process (25) to obtain a finished product.

본 발명의 다른 방법으로서 상부몰드의 표면에 무늬형성물을 부착한 후 상부몰드를 성형물이 주입된 하부몰드에 결합하여 무늬형성물과 성형물이 일체로 성형되도록하여도 동일한 효과를 얻게 되는 것이다. As another method of the present invention, the same effect is obtained by attaching the patterned product to the surface of the upper mold and then combining the upper mold with the lower mold into which the molded product is injected.

본원발명은 특정제품에 국한됨이 없이 욕실용품인 욕조, 세면기 건축용재인 외장패널, 전등갓 등에 적용이 가능한 것이다.     The present invention is not limited to a specific product is applicable to bath tubs, washbasin building panels, lampshade, etc.

상술한 바와 같이 본 발명에 의하면 혼합물과 성형물의 점도의 차이에 의해서 외부로 드러나는 질감이 천연대리석의 무늬와 극히 유사한 미감을 갖는 우수한 제품을 얻을 수 있는 유용한 발명인 것이다.As described above, according to the present invention, it is a useful invention to obtain an excellent product having an aesthetic feeling that is very similar to that of natural marble due to the difference in viscosity of the mixture and the molding.
