본 발명은 표면보호용 테이프의 제조방법에 관한 것으로, 특히 플라스틱계판, PCV판, 멜라민판의 성형품에 대하여 양호한 점착성, 응집성, 내열성 및 재박리성을 갖는 표면보호용 테이프의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a surface protective tape, and more particularly to a method for producing a surface protective tape having good adhesion, cohesion, heat resistance and re-peelability to molded articles of plastic, PCV, and melamine plates.
아크릴계 점착제를 도포하여 가공한 종래의 테이프는 폴리아크릴산 알킬에스테르를 주성분으로 하고, 페놀수지, 로진변성수지, 석유계 변성수지 등의 점착성 부여제를 보조성분으로 하여, 유리전이 온도가 높은 단량체를 일부 공중합시켜 히드록시(OH)기를 함유케하여 이소시아네이트계 화합물의 경화성능을 향상시킨 수지를 도포한 것이다.The conventional tape processed by applying an acrylic pressure sensitive adhesive has polyacrylic acid alkyl ester as a main component, and a tackifier such as phenol resin, rosin modified resin, and petroleum modified resin as auxiliary components, and a part of the monomer having high glass transition temperature is used. The resin is coated with a resin containing copolymerized hydroxy (OH) groups to improve the curing performance of the isocyanate compound.
일반적으로, 보호용 테이프는 폴리에틸렌의 표면에 점착제를 도포하거나 특수한 경우, 폴리에스테르 필름의 표면에 점착제를 도포하여 금속, 플라스틱계판, PVC판 또는 멜라민판 등의 표면에 입혀줌으로써 긁힘등을 방지하는데 사용되어 왔으나, 종래의 점착제용 아크릴수지를 도포한 폴리에틸렌이나 폴리에스테르 필름은 내열성이 적어서 보호되는 플라스틱의 성형시 플라스틱위에 입혀진 필름이 녹거나 훼손되어, 균일하게 입히는 것이 불가능하였다. 이러한 문제점을 해결하기 위하여, 내열성이 양호한 실리콘계 점착제를 폴리에스테르 필름에 도포하여 보호용 테이프로 사용하였으나, 투명도가 좋지 않아서 피착제의 무늬 및 디자인이 잘 보이지 않는 단점이 있다. 또한, 표면보호용 테이프는 점착성, 응집성, 내열성 및 재박리성이 좋아야 하는데 종래의 보호용 테이프는 플라스틱 성형후 열을 받으면 테이프와 접착제와의 분리현상으로 점착제가 금속판, 플라스틱계판, PVC판 또는 멜라민판에 남아서 외관이 불량하고 더러워지는, 점착제 전이현상이 나타나며 점착성 및 응집성이 저하되는 문제점이 있었다.Generally, a protective tape is used to prevent scratches by applying an adhesive on the surface of polyethylene or in a special case, by applying the adhesive on the surface of a polyester film and coating it on a surface of a metal, a plastic board, a PVC board, or a melamine board. However, the polyethylene or polyester film coated with a conventional acrylic resin for pressure-sensitive adhesive has a low heat resistance, so that the film coated on the plastic melts or is damaged during molding of the plastic to be protected. In order to solve this problem, a silicone-based adhesive having good heat resistance was applied to a polyester film and used as a protective tape. However, since the transparency is not good, the pattern and design of the adherend are not easily seen. In addition, the surface protection tape should have good adhesiveness, cohesiveness, heat resistance and re-peelability. The conventional protection tape is a phenomenon that the adhesive is separated from the tape and the adhesive when heated after plastic molding, and the adhesive is applied to the metal plate, plastic plate, PVC plate or melamine plate. Remaining poor appearance and dirty, the adhesive transition phenomenon appears and there was a problem that the adhesiveness and cohesiveness is lowered.
본 발명의 목적은 상기한 바와 같은 종래 기술의 단점을 해소하여, 플라스틱계판, PVC판, 금속화장판 또는 멜라민판의 성형품에 대하여 양호한 점착성, 내열성, 응집성 및 재박리성을 갖는 표면보호용 테이프를 제공하는데 있다.The object of the present invention is to solve the disadvantages of the prior art as described above, to provide a surface protective tape having good adhesion, heat resistance, cohesiveness and re-peelability to molded articles of plastic board, PVC board, metal cosmetic board or melamine plate.
