摘　　要：松香与马来酸酐进行Diels-Alder反应合成马来海松酸酐(MPA),与环氧氯丙烷进一步反应生成松香基环氧树脂,以马来海松酸酐(MPA)做固化剂固化松香环氧树脂,利用差示扫描量热仪、动态力学谱仪、热重分析仪等分析手段,对该体系固化产物进行固化动力学和热降解动力学研究。结果表明,质量比为5∶5的环氧树脂/马来海松酸酐体系固化后玻璃化转变温度达53.2℃,平均固化反应活化能为52.29kJ/mol;固化物在10℃/min时初始分解温度为211.9℃,最大分解温度为347.7℃,最终分解温度为639.0℃。Maleopimarate(MPA)was synthesized from rosin and maleic anhydride by Diels-Alder reaction,which was used reaction with epichlorohydrin to synthesize rosin-based epoxy resin(MPAER). The dynamic mechanical property,cure kinetics,and thermal stability were characterized by DMA,DSC and TG.It showed that the glass transition temperature of cured MPAER was 53.2 ℃ when the mass ratio of MPAER with MPA was 5∶5,and the average curing activation energy(Eca)was 52.29kJ/mol.When the heating rate was 10 ℃/min,the initial degradation temperature(Tid),was 211.9 ℃,the fast thermal degradation temperature was 347.7 ℃,and the final degradation temperature was 639 ℃。
