본 발명은 고광택 및 내마모성이 우수한 인조대리석의 크리스탈 코팅방법에 관한 것으로, 보다 상세하게는 표면의 특성상 도료의 도막 코팅이 어려운 인조대리석에 인조대리석과의 결합성이 우수한 도료 조성물을 코팅하여서 내마모성 및 내오염성을 강화하고 고광택을 제공하는 인조대리석의 크리스탈 코팅방법에 관한 것이다.The present invention relates to a crystal coating method of artificial marble excellent in high gloss and wear resistance, and more particularly, by coating a coating composition excellent in binding properties with artificial marble on the artificial marble difficult to coat the coating due to the characteristics of the surface The present invention relates to a crystal coating method of artificial marble that enhances contamination and provides high gloss.

인조대리석은 천연석분이나 광물을 아크릴, 불포화폴리에스테르, 에폭시 등과 같은 수지성분이나 시멘트와 배합하고 각종 안료 및 첨가제 등을 첨가하여 천연대리석의 질감을 구현한 인조 혼합체를 통칭하는데, 대표적으로는 아크릴계 인조대리석, 폴리에스테르 인조대리석, 시멘트 인조대리석 또는 석회석 인조대리석 등을 들 수 있다.Artificial marble combines natural stone powder and minerals with resin components or cement such as acrylic, unsaturated polyester, epoxy, etc., and adds various pigments and additives to artificial marble that collectively realizes the texture of natural marble. Marble, polyester artificial marble, cement artificial marble or limestone artificial marble.

이들 인조대리석은 우수한 가공성과 내후성 및 시공성을 가지고 있을 뿐만 아니라 천연대리석과 비교하여 가볍고 비다공질이며, 천연대리석에 뒤떨어지지 않 는 우수한 색조와, 뛰어난 강도 및 내후성을 가지고 있으며, 더욱이 목질과 비견될만한 우수한 가공성을 가지고 있어 천연대리석과 차별화될 수 있다. 따라서, 상기 인조대리석은 각종 싱크대 상판재료, 드레싱 테이블, 세면대, 테이블, 벽재, 바닥마루 재료, 가구, 내장재, 간접 조명패널, 인테리어 소품 등과 같은 다양한 용도에 사용되고 있으며, 그 중 85% 이상이 일반 주택이나 아파트의 주방용 상판으로 이용되고 있다.These artificial marbles not only have excellent processability, weatherability and workability, but are lighter and nonporous than natural marble, and have excellent color tone, excellent strength and weather resistance that are inferior to natural marble, and are also comparable to wood. Because of its processability, it can be differentiated from natural marble. Therefore, the artificial marble is used for various applications such as various kinds of sink top plate material, dressing table, wash basin, table, wall material, flooring material, furniture, interior materials, indirect lighting panel, interior accessories, more than 85% of them It is also used as a kitchen top for apartments.

이러한 인조대리석은 최근 건축물 내장재로서 그 수요가 증가됨에 따라 그 외형 및 품질을 향상시키기 위한 연구도 활발히 진행되고 있는데, 인조대리석을 합성하는 원료들을 개선하거나 새로운 첨가제를 개발하는 등의 일련의 방법들이 제안되었다.Recently, as the demand for building interior materials increases, the artificial marble is being actively researched to improve its appearance and quality. A series of methods, such as improving raw materials for synthesizing artificial marble or developing new additives, are proposed. It became.

한편, 인조대리석이 주방이나 작업실 등에서 작업대 상판으로 사용되려면 마모성이나 오염성 등이 다소 취약하기 때문에 작업시 쉽게 스크래치가 발생되고 이 스크래치에 오염물질이 고착되어 표면 광택이 저하되고 변색이 일어나거나 그로 인해 세균의 번식이 일어나는 등의 문제점을 해결하여야 한다.On the other hand, if artificial marble is used as a work table top in kitchen or work room, it is easily vulnerable or contaminated, so scratches are easily generated during work, and contaminants adhere to these scratches, resulting in surface gloss deterioration and discoloration. Problems such as breeding should occur.

이러한 문제점을 해결하기 위하여 광택제나 항균성 도료를 표면에 코팅하는 방법이 시도되었으나 인조대리석 표면은 마찰력이 매우 낮아서 도료가 코팅되기 어렵고 코팅된 후에도 쉽게 박리된다. 사포나 그라인더로 인조대리석 표면의 마찰력을 높여서 도료의 코팅이 용이하도록 하는 방법은 표면의 광택을 저하시키므로 바람직하지 않다.In order to solve this problem, a method of coating a surface with a varnish or antimicrobial paint has been attempted, but the surface of artificial marble is very low in friction, and thus the paint is difficult to be coated and is easily peeled off after coating. It is not preferable to increase the friction of the surface of the artificial marble with sandpaper or grinder to facilitate the coating of the paint, since it lowers the gloss of the surface.

본 발명자들은 상기한 바와 같은 문제점을 해결하기 위하여 예의 연구한 결과, 마찰력이 낮은 인조대리석의 표면에 안정적으로 도막을 형성하므로써 인조대리석에 내마모성, 내오염성 및 고광택을 제공할 수 있는 도료 부착성이 개선된 크리스탈 코팅제 도료 조성물을 개발하게 되었다.The present inventors earnestly studied in order to solve the above problems, and as a result, the coating film is stably formed on the surface of the artificial marble having low frictional force, thereby improving paint adhesion that can provide wear resistance, stain resistance and high gloss to the artificial marble. Developed a crystal coating composition.

The blending amount of the additive may be used in an amount of 5 to 10% by weight based on 100% by weight of the total coating film composition. When 10% by weight or more is used, the gloss, abrasion resistance, or fouling resistance of the artificial marble may be reduced.

본 발명에 있어서는, 먼저 인조대리석의 표면을 샌딩 처리하여 그 표면 상에 거칠기(roughness)를 제공한다. 샌딩 처리는 특별한 제한은 없으며 표면의 미세한 스크래치나 오염 등을 제거하고 다음 단계에서의 도막 코팅을 촉진하기 위해 공지된 기술에 의해 실시된다. 예를들면 사포를 이용하는 원형 샌더기나 그라인더를 이용하여 샌딩 처리할 수 있다.In the present invention, first, the surface of the artificial marble is sanded to provide roughness on the surface. The sanding treatment is not particularly limited and is carried out by a known technique to remove fine scratches or dirt on the surface and to promote coating coating in the next step. For example, sanding can be done with a sander or grinder using sandpaper.

샌딩 처리에 의해 표면에 거칠기가 제공된 인조대리석은 물 또는 세척제를 이용하여 세척한다. 이때, 바람직하기로는 세척제를 사용하는데, 세척제를 사용하여 표면의 오염물질, 특히 유분을 제거한다. 세척 후에는 인조대리석의 표면에 수분이 남지 않도록 완전히 건조시킨다.The artificial marble provided with the roughness on the surface by the sanding treatment is washed with water or a cleaning agent. In this case, a cleaning agent is preferably used, which removes contaminants, especially oil, from the surface. After cleaning, dry completely so that no moisture remains on the surface of artificial marble.

세척 후 건조시킨 인조대리석의 표면에 본 발명에 따른 도료 조성물을 코팅한다. 코팅 방법은 이 분야에서 알려진 공지의 기술, 예를들면 스프레이 코팅, 롤 코팅, 커튼 코팅, 필름 코팅, 붓 등 가능한 도포 공법을 모두 적용할 수 있다. 바람직하기로는 스프레이 코팅을 적용한다.The coating composition according to the present invention is coated on the surface of the artificial marble dried after washing. The coating method may apply all known techniques known in the art, such as spray coating, roll coating, curtain coating, film coating, brush, etc., and all possible application methods. Preferably spray coating is applied.

본 발명에 따른 도료 조성물을 에어건 용기에 담아 콤프레셔를 이용하여 인조대리석 표면에 스프레이한다. 도료 조성물은 인조대리석 상판에 형성되는 도막의 두께가 20 내지 40 ㎛의 범위가 되도록 스프레이한다. 스프레이 작업을 완료한 후에는 일정시간, 예를들면 약 20분 정도 방치하여 도료가 평탄화(레벨링)되어 도막을 형성하도록 한다.The coating composition according to the present invention is placed in an air gun container and sprayed onto the surface of artificial marble using a compressor. The coating composition is sprayed such that the thickness of the coating film formed on the artificial marble top plate is in a range of 20 to 40 µm. After the spraying operation is completed, it is allowed to stand for a certain time, for example, about 20 minutes so that the paint is flattened (leveled) to form a coating film.
