| 摘 要： | 为改善EP的表面性能,利用合成的星型端硅氧烷低聚物(TPSi)对环氧树脂(EP)改性,通过溶胶-凝胶技术固化复合体系.研究了复合体系的固化机理及表面性能.结果表明:TPSi改性EP的复合体系中,存在着3种固化机理.当TPSi含量不超过30%时,3种不同机理固化反应的发生导致体系的相容性增加.与EP-胺固化样相比,改性后试样的临界表面张力增加.偶联剂(KBE-9103)的加入,TPSi改性固化体系表面张力增大.

| Abstract: | （Epoxy resin） EP was modified with star siloxane-terminated oligomers（TPSi） in order to improve surface properties of epoxy resin.The modified systems were cured with amino curing agent via amino-glycidyl reaction and sol-gel technology.The surface properties and curing mechanism of composite systems with new star siloxane-terminated oligomers were investigated in this passage.It was showed that the composite systems had three different curing mechanisms.The compatibilities of composite systems increased when TPSi was less than 30% in the composite systems.The critical surface intension of composite systems was increased compared with EP-amino curing sample.The critical surface intension of composite systems were improved when KBE-9103 were added in the samples. |
