邻苯二甲酸型不饱和聚酯树脂与双环戊二烯型不饱和聚酯树脂性能比较研究

摘要

We do comparative study on comprehensive performance of phthalic acid type (O-type) Unsaturated Polyester Resin (UPR) and dicyclopentadiene type (DCPD-type) Unsatu-Rated Polyester Resin(UPR) by testing the statistics of curing gel time, the exothermic peak temperature, the air drying property, Barcol hardness, tensile properties, and bending performance. The results found: (1) The mechanical properties of O-type UPR is superior to the mechanical properties of DCPD-type UPR. (2) The curing properties of O-type UPR is superior to the curing properties of DCPD-type UPR. (3) The air drying property of DCPD-type UPR is superior to the air drying property of O-type UPR.%　　通过测试邻苯二甲酸型(邻苯型)不饱和聚酯树脂(UPR)和双环戊二烯型(DCPD 型)不饱和聚酯树脂(UPR)的固化胶凝时间、放热峰温度、气干性能、巴氏硬度、拉伸性能、弯曲性能数据，对两种树脂的综合性能做了比较研究.结果发现：1)邻苯型 UPR 的力学性能(如巴氏硬度、拉伸性能、弯曲性能)优于 DCPD 型 UPR.2)邻苯型 UPR 的固化性能(固化胶凝时间、放热峰温度)优于 DCPD 型 UPR.3)DCPD 型 UPR 的气干性能优于邻苯型 UPR.
