인조 라임스톤용 조성물{Composition for artficial lime-stone}Composition for artificial limestone {Composition for artficial lime-stone}

본 발명은 인조 라임스톤용 조성물로서, 보다 상세하게는 실제 자연 대리석의 색상과 패턴을 동일하게 구현할 수 있는 인조 라임스톤용 조성물에 관한 것이다.The present invention relates to a composition for artificial limestone, and more particularly to a composition for artificial limestone that can embody the color and pattern of the actual natural marble in the same way.

라임스톤은 석회암의 종류로 입자가 곱고 색상이 부드러우며 가공이 용이하고 무광이나 반광 상태인 혼드 마감으로 많이 사용한다. 수분의 흡수율이 높은 석재로써 오염물질(음료수, 손때, 왁스, 습기)에 노출이 쉬우며 변색이 쉽고 석재 자체의 특성상 강도가 매우 약하여 스크래치가 잘 나며 광택이 빨리 손상된다. 따라서, 초기의 관리가 매우 중요한 마감재라 할 수 있으며 오염원을 처음 단계에서부터 차단하여 본래의 질감을 표현하기 위해서는 세심한 관리가 필요한 석재이다. 하지만, 천연 라임스톤의 제한된 공급량 때문에, 천영 라임스톤과 동일, 유사한 효과를 발생시키는 인조 라임스톤에 대한 개발이 활발하나, 여전히 자연 라임스톤과는 색상, 패턴에서 차이가 난다. Limestone is a type of limestone with fine grain, soft color, easy processing, and often used as a matt finish or semi-gloss horn finish. As a stone with high water absorption rate, it is easy to be exposed to contaminants (beverage, hand, wax, moisture), discoloration is easy, and the strength of the stone itself is very weak, so it scratches well and the gloss is damaged quickly. Therefore, the initial management is a very important finishing material and it is a stone that requires careful management to express the original texture by blocking the source from the initial stage. However, due to the limited supply of natural limestone, the development of artificial limestone that produces the same and similar effects as Cheonlim limestone is active, but still differs in color and pattern from natural limestone.

따라서, 본 발명이 해결하려는 과제는 실제 자연 대리석의 패턴과 색상을 그대로 구현할 수 있으며, 기계적, 물리적 특성이 우수한 대리석을 제조하기 위한 인조 라임스톤용 조성물을 제공하는 것이다.Accordingly, an object of the present invention is to provide a composition for artificial limestone for producing marbles having excellent mechanical and physical properties, which can be implemented as it is and the pattern and color of actual natural marble.
