광경화에 의한 PVC 바닥상재 코팅은 PVC 바닥상재의 질을 향상시키기 위하여 관련 산업체에서 널리 사용되고 있는 기술이다. 본 연구에 사용한 폴리우레탄 아크릴레이트 수지는 반응성 모노머, 광개시제, 기타 첨가제를 배합하여 제조하였으며, 올리고머는 상용화된 지방족 우레탄 아크릴레이트를 사용하였다.
PVC 바닥상재용으로 사용되는 내마모성이 없는 우레탄 아크릴레이트 수지에 내마모성을 갖는 3가지 종류의 Al₂O₃(Al-160SG-3), Al(OH)₃(SH-8W) 및 SiO₂(KS-5000) 파우더를 수지의 양 대비 10~30 wt.%로 증가시키며 첨가하였다. 내마모성을 갖는 파우더가 첨가된 우레탄 아크릴레이트 수지를 링밀(Ring Mill)로 혼합하여 수지의 내마모성을 향상시킨 하드 코팅액을 제조하였다.
제조한 하드 코팅액은 코팅층의 두께조절이 가능한 바코팅(Bar-coating)방법으로 PVC 바닥상재에 코팅한 후 내마모성, 연필경도, 부착력, 코팅두께 등의 코팅층에 대한 표면물성을 평가하였다.
연구결과, 우레탄 아크릴레이트 수지에 Al₂O₃파우더 30 wt.%를 배합하여 제조한 하드 코팅액이 내마모성 1등급, 연필경도 H, 부착력 5B로 가장 좋은 물성을 보였으며, 전반적으로 입자크기가 작고, 파우더 함량이 많아지고, 코팅두께가 두꺼울수록 경도 및 내마모성이 우수한 것으로 나타났다.

The purpose of this study was to make a formulation of UV-curable polyurethane acrylate coating for poly(vinyl chloride) (PVC) floor tiles. UV-curable coating resins basically included polyurethane acrylate oligomers, acrylate monomers, photoinitiators and other additives. The used oligomers were commercial aliphatic polyurethane acrylates. The investigation was conducted to achieve an optimal domain of composition and desired coating effect.
The design of experiment aimed to select a set of formulation components dependent on achieving good adhesion to PVC surface. Adhesion values were determined by conventional tape test method. In the study another important coating property we focused on was gloss. The dependence of gloss on the content of resins was investigated. The application performance of the coatings obtained is to aim for a balance of a good adhesion and required gloss. The coating resins were characterized by FTIR.
A series of non-glossy, half-glossy, and glossy coating resins were formed that included different mixing ratios. The adhesion of coatings all reached maximum value, 5B.
This study was on development of UV-cured hard coating compositions which have more improved abrasion resistance than UV-cured polyurethane acrylate resins, to prevent a surface of widely used PVC tile as a constructive material from being scratched.
To improve UV cured polyurethane acrylate coating for PVC tiles, silica, alumina and aluminium hydroxide particles with a few microns in size have been blended with polyurethane acrylate coating resins. We added powder substances of different abrasion resistance level, Al₂O₃(Al-160SG-3), Al(OH)₃(SH-8W), SiO₂(KS-5000), etc., to the resin, changing their contents from 10% to 30% against quantities of resin, and mixed them using ring-mill. After coating on PVC tiles with hard coating solution using bar-coating method that can adjust a thickness, the resulted coating properties were achieved including abrasion resistance, pencil hardness, adhesion between the coating and the substrate, thickness of coatings, and so on.
As a result, a hard coating added 30% Al₂O₃powder to the resin had the finest surface properties-the first grade in abrasion resistance, H in pencil hardness, 5B, in adhesive power. Therefore, a hard coating which showed excellent solidity and abrasion resistance has smaller particle size, higher powder content, and thicker coating thickness. In the case of UV-curable hard coating, the powders added into the coating resins had no influence on the adhesion between the coating and the substrate.
