摘要(Abstract)：

将玉米秸秆酶解木质素与双酚A环氧树脂混合,在不同温度下预处理一定时间,用以改性环氧树脂。通过改性后树脂黏度、固化反应过程、固化后树脂的玻璃化转变温度、凝胶含量以及老化不同时间后树脂力学性能的测试,研究了处理温度对酶解木质素改性环氧树脂性能的影响。结果表明,改性后环氧树脂的黏度随处理温度的提高而增加,改性树脂/聚酰胺混合体系的固化峰值温度随处理温度的提高而降低;玻璃化转变温度和凝胶含量随处理温度的提高而增大;高温预处理的改性树脂固化物的弯曲强度均有不同程度的提高,老化后,材料的弯曲强度先升高,后降低,冲击强度则随老化时间的延长呈现持续降低的趋势。

关键词(KeyWords)： 酶解木质素;环氧树脂;处理温度;性能
