제1도는 본 발명의 금속 광택을 갖는 인조대리석 제품의 사진을 나타낸 것이다. 1 shows a photograph of an artificial marble product having a metallic luster of the present invention.

발명의 분야Field of invention

본 발명은 금속 광택을 갖는 인조 대리석 조성물에 관한 것이다. 보다 구체적으로, 본 발명은 아크릴계 인조대리석용 조성물에 특정 크기의 알루미늄 분말을 첨가시킴으로써, 고급스러운 금속 광택을 갖는 인조 대리석 조성물에 관한 것이다. The present invention relates to an artificial marble composition having a metallic luster. More specifically, the present invention relates to an artificial marble composition having a luxurious metallic luster by adding aluminum powder of a specific size to the composition for acrylic artificial marble.

발명의 배경Background of the Invention

인조대리석은 최근 건축 내장재로 많이 사용되고 있으며, 그 사용되는 베이 스 레진(Base resin)에 따라 크게 아크릴계와 불포화 폴리에스터계의 두 가지 종류로 구분된다. 이 중 아크릴계 인조 대리석은 수지 자체의 은은한 투명성과 고급스러운 질감 및 우수한 내후성 등의 장점으로 인해 여러 가지 용도로 사용되고 있으며, 그 수요가 계속 증가하고 있다.Artificial marble is widely used as a building interior material recently, and it is classified into two types, acrylic and unsaturated polyester, depending on the base resin used. Among them, acrylic artificial marble is used for various purposes due to its soft transparency, luxurious texture, and excellent weather resistance, and its demand is continuously increasing.

예를 들면, 씽크대 상판, 세면 화장대의 상판, 은행 및 일반 매장의 접수대 등 각종 카운터의 상판, 내벽재, 각종 인테리어 조형물 등의 소재로서 그 사용이 확대되고 있다.For example, its use is being expanded as a material for counter tops, interior walls, various interior sculptures, such as sink tops, vanity tops, banks and reception desks in general stores.

한편, 최근에는 금속 특유의 차갑고 현대적인 느낌 때문에 각종 인테리어 조형물 등의 소재로 금속의 사용이 증가하고 있으나, 자재비 상승 및 부식 등으로 인해 그 사용이 제한되고 있다. On the other hand, in recent years, the use of metal as a material for various interior sculptures, etc. due to the cold and modern feeling unique to the metal, but its use is limited due to the increase in material costs and corrosion.

따라서 실용성 있는 인조대리석 소재를 이용하여 금속 광택의 효과를 낼 수 있다면, 기존의 금속 재료의 사용으로 인한 문제점을 해소할 수 있을 것이다. Therefore, if it is possible to produce the effect of metallic luster by using a practical artificial marble material, it will be able to solve the problems caused by the use of existing metallic materials.

그러나, 지금까지 개발되어온 인조대리석 소재는 천연 대리석에 가까운 질감을 내는 데에만 치중하였을 뿐, 아직까지 금속 광택을 내는 대리석 제품에 대한 개발은 미비하여 보다 다양한 소비자의 욕구에 부응하지는 못하고 있다. However, the artificial marble material that has been developed so far has focused only on the texture of natural marble, and the development of marble products that give off metallic luster is not sufficient to meet the needs of various consumers.

따라서 본 발명자는 상기의 문제점을 해결하기 위하여 아크릴계 인조대리석용 조성물에 특정 크기의 알루미늄 분말을 특정한 함량으로 첨가시킴으로써, 금속 특유의 독특한 느낌과 금속 광택을 갖는 인조 대리석 조성물을 개발하기에 이른 것이다.Accordingly, the present inventors have developed an artificial marble composition having a unique feel and metallic luster that is unique to metals by adding a specific amount of aluminum powder to a composition for acrylic artificial marble in order to solve the above problems.

본 발명의 목적은 금속 광택을 갖는 인조 대리석 조성물을 제공하기 위한 것이다.It is an object of the present invention to provide an artificial marble composition having a metallic luster.
