【摘要】 用二氨基二苯基砜为固化剂,在一定条件下固化酚醛环氧—环硫树脂。并用红外分析的方法对固化机理进行了研究。通过凝胶化时间分别计算出酚醛环氧树脂/二氨基二苯基砜和酚醛环氧—环硫树脂/二氨基二苯基砜的固化反应的活化能。并且根据不同升温速率下的DSC数值推算出该反应的固化工艺。更多还原

【Abstract】 Using4,4-diaminobisphenol sulfone(DDS)as the hardener,the curing behavior and the reaction mechanism of novalac epoxy-episulfide resin are studied under a cured condition by FI-IR.According to the results of gel time,the activation energy is calculated.Meanwhile,the curing process of novalac epoxy-episulfide resin/DDS is studied according to non-isothermal DSC.更多还原
