摘　　要：用多羟基丙烯酸树脂(MPA)对漆酚缩甲醛 (UFP)涂料进行改性,制备了兼具耐热和抗紫外性能的UFP/MPA互穿聚合物网络涂料,用IR、TG -DSC、DMTA等进行了结构表征和性能测试。结果表明,当m(UFP)∶m(MPA) =5∶2时,UFP与MPA相互交联、缠结;其涂膜既耐热又抗有机溶剂,光照 7d后仍兼具有UFP和聚丙烯酸酯的优良性能:硬度为 6H、柔韧性为 1mm、附着力为 1级。The urushiol-formaldehyde polymer(UFP) coating was modified with multihydroxyl polyacrylate(MPA) to prepare the interpenetrating polymer network(IPN) of UFP/MP A. The structure and mechanical property of the IPNs were examined by IR, TG/DSC and DMTA. The results show that the IPN was formed by the cross-linking and en tanglement of UFP and MPA at m(UFP)∶m(MPA)=5∶2 and e xhibited the charac-teristic of both UFP and MPA coatings , i.e., heat resistance and solvent resistance with pencil hardness of 6H , adhesion of 1 gr ade and flexibility(1 mm) after irradiation with ultraviolet light for 7 days.
