摘　　要：研究了固化温度、固化促进剂、聚酯树脂表面张力及流平剂对低温固化消光粉末涂料消光性能的影响,并对低温固化消光粉末涂料的固化程度进行了表征。结果表明:提高固化温度、加大聚酯树脂表面张力差及使用适量的流平剂均有利于改善异氰尿酸三缩水甘油酯(TGIC)体系低温固化消光粉末涂料的消光性能,过量添加固化促进剂则会起到负面作用;要提高低温固化消光粉末涂层的固化程度,有赖于研发适用于低温固化的消光剂。The effects of curing temperature,curing accelerator,surface tension of polyester resin and flatting agent on the extinction property of low temperature curing matting powder coatings were studied,and the curing degree of low temperature curing matting powder coatings was characterized.The results show that increasing the curing temperature,increasing the surface tension difference of polyester resin and using a proper amount of flatting agent can improve the extinction property of low-temperature curing matting powder coatings based on TGIC,while excessive addition of curing accelerator will have a negative effect.To improve the curing degree of low temperature curing matting powder coatings,it is necessary to develop a matting agent suitable for low temperature curing.
