Abstract
Description
본 발명은 가구마감재 전용 ASA수지조성물 및 이를 이용해 제조된 가구마감재에 관한 것으로서, 보다 상세하게는 목재와의 접착력, 내충격성, 광택, 경도, 내후성, 내스크랫치성 및 내화학성이 우수한 가구마감재 전용 ASA수지조성물 및 이를 이용해 제조된 가구마감재에 관한 것이다.
The present invention relates to an ASA resin composition for furniture finishing materials, and more particularly to a furniture finishing material which is excellent in adhesion to wood, impact resistance, gloss, hardness, weather resistance, scratch resistance and chemical resistance ASA resin composition and a furniture finish made using the same.
염화비닐수지(Polyvinylchloride, PVC)는 가격이 저렴하고 난연성, 내화학성 및 제품의 경도조절이 용이한 장점을 가진다. 따라서 이러한 염화비닐수지로 제조된 가구용 데코시트나 엣지밴드가 제공되고 있다. Polyvinylchloride (PVC) is cheap and has advantages of easy flame retardance, chemical resistance and hardness control of product. Accordingly, a decorative sheet or an edged band for furniture made of such a vinyl chloride resin is provided.
그러나 염화비닐수지는 내후성, 착색성 및 내후변색성이 낮기 때문에, 장기간 사용시 표면이 쉽게 닿거나 쉽게 변색된다. 뿐만 아니라 염화비닐수지는 환경호르몬 추정물질로 취급되는 프탈레이트계의 가소제를 사용한다. 따라서 염화비닐수지는 친환경문제로 인해 가구용 마감재로 사용이 지양되고 있다. However, since the vinyl chloride resin has low weatherability, coloring property and weathering resistance, it can easily touch the surface or discolor easily during long-term use. In addition, vinyl chloride resin uses a phthalate plasticizer treated as an environmental hormone estimation substance. Therefore, vinyl chloride resin is being used as a finishing material for furniture due to environmental friendliness.
한편, ABS수지(Acrylonitrile-Butadiene-Styrene Co-Polymer) 역시 가격이 저렴하고, 충격강도, 치수안정성, 친환경성, 착색성이 우수한 장점으로 인해, 데코시트나, 엣지밴드 등의 가구용 마감재 원료로 사용되고 있다. On the other hand, ABS resin (Acrylonitrile-Butadiene-Styrene Co-Polymer) is also used as a raw material for furniture finishing materials such as decor sheet and edge band due to its low cost, excellent impact strength, dimensional stability, environmental friendliness and coloring .
그러나 ABS수지는 내화학성, 내후성 및 내후변색성이 낮기 때문에 햇빛이 많이 노출되는 곳에서는 쉽게 변색된다. 따라서 ABS수지로 성형된 제품은 내화학성과 내후성이 우수한 별도의 코팅필름을 라미네이팅하여야 하는 번거로움이 따른다.However, since ABS resin has low chemical resistance, weather resistance and weathering resistance, it easily discolors in a place exposed to a lot of sunlight. Therefore, a product molded from ABS resin is troublesome to laminate a separate coating film having excellent chemical resistance and weather resistance.

In addition, since the ASA resin composition does not require the use of a plasticizer in the extrusion molding, a product which is different from conventional vinyl chloride resins is provided in accordance with environment-friendly issues.
