光固化漆酚膜的性能研究

Polyurushiol films have been successfully prepared under UV irradiation in the presence of air, which is a new method for fast dry of lacquer. The films have been characterized by pencil hardness method, Fourier transform infrared spectroscopy (FT-IR), Electron spin resonance (ESR), elementary analysis and TG. The results suggested that UV cuing of urushiol was different in mechanism from lacquer polymerized by laccase-catalyzed oxidation. It isn’t an aerobic oxidative polymerization, but initiated by radicals under UV irradiation. And the films had excellent physico-mechanical propertise, resistance against chemical media and thermo-stability.
