Abstract
Two functional urethane acrylates were synthesized by using polycarprolactonediol (PCLD) and diisocyanate. The synthesized fuctional urethane acrylate was mixed with butyl acrylate(BA) or adhesion promoters, and their properties were investigated. To synthesize an excellent transparent urethane acrylate, isophorone diisocyanate(IPDI) was used. In addition, the effect of adding butyl acrylate for the improvement of shrinkage of urethane acrylate was studied. The results showed that the addition of butyl acrylate improved the shrinkage, and the optimum butyl acrylate content was 15 wt%. Both 2-ethyl hexyl acrylate (2-EHA) and ethyl acrylate(EA) were polymerized at $85^{\circ}C$ for 4 hrs to use as adhesion promoters, and the polymerized adhesion promoters were mixed to the UV-curing resin. The results showed that the adhesion properties increased with the increase of adhesion promoters content up to 15 wt%.
