인조대리석{Artificial Marble}Artificial Marble

본 발명은 금속계 칩을 사용하여 금속성 광물이 포함된 듯한 질감을 갖는 인조대리석에 관한 것이다.The present invention relates to an artificial marble having a texture that seems to contain metallic minerals using a metal-based chip.

천연석을 대신하여 건축 및 인테리어용 자재로 널리 사용되고 있는 인조석은 그 표면에 표현된 무늬 또는 패턴에 따라 인조대리석, 인조화강석 등으로 불리기도 하나, 통상적으로는 천역석의 질감이 구현된 인조석을 총칭하여 인조대리석이라 한다.Artificial stone, which is widely used as a building and interior material instead of natural stone, may be called artificial marble or artificial granite according to the pattern or pattern expressed on its surface.In general, artificial stone is generally referred to as artificial stone embodying the texture of natural stone. It is called marble.

이러한 인조대리석은 제조에 사용된 수지 성분에 따라 불포화 폴리에스테르계 인조대리석, 아크릴계 인조대리석 등으로 다시 분류될 수 있는데, 불포화 폴리에스테르계 인조대리석의 경우, 불포화 폴리에스테르 수지 시럽에 무기계 골재, 경화 개시제, 촉진제 및 안료 등을 혼합한 후, 그 수지혼합물을 몰드에 균일하게 담아 진공 압축 성형한 다음, 표면 연마처리하여 제조된다.Such artificial marble can be further classified into unsaturated polyester artificial marble, acrylic artificial marble, etc. according to the resin component used in the manufacture. After mixing the accelerator, the pigment and the like, the resin mixture is uniformly contained in a mold, vacuum compression molding, and then prepared by surface polishing.

그런데, 종래의 경우, 인조대리석은 단색으로 제조되거나, 서로 다른 색상의 안료를 사용한 2가지 이상의 수지혼합물들을 서로 혼합하여 다색톤을 갖도록 제조되거나, 인조대리석용 칩을 이용하여 천연석의 질감을 갖도록 제조되었던 바, 천연 석 질감의 표현이라는 점에서 종래기술은 상당한 성과가 있었으나, 다양한 소비자의 디자인적 욕구를 반영하거나 보다 고급스러운 질감을 표현하는데에는 한계가 있었다.By the way, in the conventional case, artificial marble is produced in a single color, or two or more resin mixtures using pigments of different colors are mixed to each other to have a multicolor tone, or manufactured to have the texture of natural stone using an artificial marble chip As a result, the prior art has been a significant achievement in terms of the expression of natural stone texture, but there was a limit in reflecting the design needs of various consumers or expressing a more luxurious texture.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것으로, 천연석 질감 뿐만 아니라 금속성 광물이 포함된 듯한 질감을 가져 메탈릭한 느낌과 함께 고급스럽고 산뜻한 느낌의 인조대리석을 제공함을 목적으로 한다.The present invention has been proposed to solve such a problem, and has an object of providing an artificial marble of a high-quality and fresh feeling with a metallic feel as well as a natural stone texture as well as a texture containing metallic minerals.
