双酚A环氧树脂改性二氧化双环戊二烯体系固化动力学分析及其性能研究
Curing dynamics analysis and properties of acycloaliphatic modified by bisphenol A(E- 51) epoxy resin
摘要
Abstract
Acycloaliphatic(CDR -0122) epoxy resin has good heat-resistance, but it is characterized by being brittle. CDR -0122 modified with different mass fraction of epoxy ( E -51) were studied. First, DSC analysis was carried out to determine the activation energy, reaction order and the best curing procedure of the modified resin. Then mechanical property and heat-resistance property of the cured modified resin were tested. The results showed that, compared with the unmodified CDR -0122, the activation energy of the modified resin system decreased slightly, and its tensile strength and flexural strength increased by 52. 38% and 54. 77% , respectively, but the glass transition temperature decreased slightly. Considering all aspects of performance, the system of CDR -0122 modified with 30 wt% E -51 is the best one.关键词
