摘　　要：本文采用SPI法测量加入不同含量低收缩添加剂 (LPA)的不饱和聚酯树脂的固化放热曲线 ,研究了低收缩添加剂的用量 ,以及中低温固化体系对不饱和聚酯树脂的凝胶时间、固化时间、放热峰温度。In this paper SPI method is used to measure the exothermic curve of unsaturated polyester resin with different content of low profile additives(LPA) during cure. The effects of low profile additive content and middle low temperature curing system on the peak temperature of exothermic reaction, curing time and gel time are investigated.
