摘要

采用原位溶胶-凝胶反应制备乙丙橡胶/ SiO2纳米复合材料。分别以乙丙橡胶（EPDM）和γ-甲基丙烯酰氧丙基三甲氧基硅烷（KH570）接枝改性的乙丙橡胶（EPDM-g-KH570）在前驱体四乙氧基硅烷（TEOS）中溶胀，再浸入含有正丁胺的催化剂溶液中催化前驱体的原位溶胶-凝胶反应。考察了不同溶剂以及催化剂含量对TEOS转化率和原位生成的SiO2粒径的影响。采用FT-IR、SEM等测试手段对纳米复合材料进行了表征。结果表明，接枝KH570后，TEOS转化率明显提高，SiO2粒径明显减小，在材料中的分散性很好。

Abstract

Ethylene-propylene diene monomer rubber-g-γ-methacryloxypropyltrimethoxysilane (EPDM-g-KH570)/SiO2 nanocomposites were prepared with the in-situ sol-gel method.Firstly

the EPDM-g-KH570 was prepared by co-irradiation.Then the graft product was soaked into tetraethylorthosilicate (TEOS).Finally

the swollen material was put into butylamine solution to catalyze the sol-gel reaction of the precursor TEOS.The influences of different solvents and concentrations of butylamine on sol-gel reaction of TEOS and the particle size of the silica obtained were studied.The morphology and microstructures of EPDM-g-KH570/SiO2 hybrid were characterized by FT-IR and SEM.The results showed that the swelling of TEOS and the equilibrium conversion of TEOS were improved significantly by grafted KH570. Compared to the ungrafted EPDM

SiO2 average diameters were smaller and had a good dispersion in the grafted EPDM.
