【摘要】 本文用环氧树脂、瑞羟基聚二甲基硅氧烷等为原料，合成了增容剂，其可使聚二甲基硅氧烷有效地分散在环氧体系中而使环氧增韧。通过红外光谱测定、扫描电子显微镜观察，热失重分析及其他力学性能测试，对该体系的增容和增韧效果进行了研究。更多还原

【Abstract】 In this paper, compatibilizers were synthesized via epoxy resin, ND-42 and hydroxy terminated polydimethylsiloxane (PDMS) by the polymeric method. In the way of using compatibilizer,PDMS was dispersed in the epoxy matrix and toughened the resin efficiently.The effects of these compatibilizers on the compatibility and the toughness of the epoxy were investigated by thd FT-IR,SEM,TGA and other mechanical property test.更多还原
