In order to find a compatibilizer for epoxy resin/silicone rubber systems, interfacial tension of epoxy resin mixed with modified silicone oils which had the compatible groups to epoxy resin was measured against RTV silicone rubber and silicone oil. From the results, it was found that one of polyether modified silicone oils (EtMPS) had strong interfacial activity. Then using the EtMPS as the compatibilizer, RTV silicone rubber or silicone diamine was filled in epoxy resin. The effects of silicone content of these materials on impact fracture energy and on peel strength were investigated. The impact fracture energy of epoxy resin was increased by the addition of RTV silicone rubber up to two times that of unmodified resin while silicone diamine had almost no effect which might be due to the small molecular weight. T-peel strengths of aluminium plates bonded by epoxy resin filled with RTV silicone rubber and with silicone diamine effectively increased with the increasing of silicone content showing the maximum at 10 ~ 20 phr. The fracture surfaces after the mechanical tests of these materials were observed by a scanning electron microscope. Many particles of silicone rubber in the size of 1 ~ 20 μ were observed over the fracture surface. 相似文献

配制了含裂解硅油的有机硅密封胶和含二甲基硅油的有机硅密封胶,分别测定其力学性能、热性能;并用四氢呋喃浸泡有机硅密封胶,过滤后将滤液进行凝胶渗透色谱(GPC)和硅核磁共振(^29Si NMR)分析。结果显示,与含二甲基硅油的有机硅密封胶相比,含裂解硅油的有机硅密封胶经水紫外、高温老化后的拉伸强度和拉断伸长率下降幅度更大,热分解温度更低;其浸出液的摩尔质量分布更宽,有4个峰存在,且29Si NMR谱图中存在M、D、T链节的特征吸收峰。通过力学性能、热性能测试,再经^29Si NMR和GPC分析,可定性检测有机硅密封胶是否含裂解硅油。 相似文献
