耐高温不饱和聚酯树脂的制备与固化
Preparation and Curing of High Temperature Resistant Unsaturated Polyester Resin
摘要
Abstract
3,6-Endomethylene-1,2,3,6-tetrahydro phthalic anhydride(NA) was synthesized from cyclopentadiene and maleic anhydride,and then high temperature resistant unsaturated polyester resin was prepared from polyhydric alcohol and NA that could partially replace phthalic anhydride.The kinetics for the unsaturated polyester resin curing was studied by means of DSC.Based on T-β extrapolation,the initial temperature,peak temperature and finish temperature of the curing process were determined as 130,145 and 185℃,respectively.The activation energy,frequency index and reaction order of the curing reaction were determined by Kissinger-Ozawa method and Crane equation as 12.93 kJ/mol,4.24×103 and 0.878,respectively.The decomposition temperature of the resin is 182℃ calculated by statistical method,which is higher than that of unsaturated dicyclopentadiene modified polyester resin obtained by half-esterifying.关键词
