Abstract

The Application of UV curing technique for poly (vinyl chloride) (PVC) floor tiles coating has improved the quality of PVC floor. Several formulations were made including acrylated oligomers based on a polyurethane were blended with reactive monomers, photoinitiators and other additives. The used oligomers are commercial aliphatic urethane acrylates. Thin films were prepared on PVC tiles by bar coating with different formulations using UV radiation. The coating resins were characterized by FTIR. The properties of UV-cured films such as gloss and adhesion were examined. The properties of UV-cured films dependent on the influence of composition and processing conditions was studied.

광경화(UV-curing)에 의한 PVC 바닥상재 코팅기술은 PVC 바닥상재 질의 개선을 위하여 사용되는 것이다. 본 연구에서 사용한 폴리우레탄 아크릴레이트 수지는 반응성 모노머, 광개시제, 그 외 첨가제를 배합하여 제조하였고, 올리고머는 상용화된 지방족 우레탄 아크릴레이트를 사용하였다. 제조한 코팅액을 바코팅(bar-coating) 방법으로 PVC 바닥상재에 코팅한 후 광경화법을 이용하여 상재표면에 코팅층을 형성하였다. 코팅에 사용된 코팅액은 FTIR로 측정하여 특성을 확인하였으며, PVC 상재 표면에 형성된 코팅층의 물성은 광택과 부착력으로 평가하였다. 코팅층의 물성은 코팅조성과 공정조건에 영향을 받았다.
