摘　　要：以腰果酚替代苯酚制备新型环氧树脂固化剂,并对制备工艺进行考察。结果表明:以腰果二酚和二乙烯三胺为原料、腰果二酚和多聚甲醛摩尔比为1∶1.2、HCl为催化剂、反应时间为1 h、反应温度为90~100℃时得到的改性环氧树脂固化剂性能最佳。此条件下得到的固化剂与E-44环氧树脂进行固化反应,表干时间为1 h,实干时间为2 h。Cardanol was used to replace phenol to prepare a new curing agent for epoxy resin,and then the preparation process was studied. The results showed that the curing agent with cardanol and diethylenetriamine as raw materials,the molar ratio of cardanol and paraformaldehyde as 1∶1. 2,HCl as catalyst,reaction time as 1 h and reaction temperature as 90 ~ 100 ℃ had best performance. The curing time of the curing agent and E-44 epoxy resin was 1 h for surface drying and 2 h for real drying.
