| 摘 要： | 介绍了一种研制的室温固化、耐高温、耐低温环氧有机硅胶黏剂.通过对胶黏剂的剪切强度分析,探讨了原料配比,偶联剂等因素对环氧有机硅胶黏剂力学性能的影响.研究表明:增韧剂在胶黏剂中含量适当时(质量比25%),能与固化剂充分反应,有机硅与环氧树脂也能获得较好的相溶性,制备的环氧有机硅胶黏剂的综合性能较优;硅烷偶联剂能改善胶膜界面层的胶接强度,提高环氧有机硅胶黏剂的剪切强度.

| Abstract: | In this paper,the high-and low-temperature resistant epoxy silicone adhesive cured at room temperature was introduced.The influence of raw material ratio,coupling agent and other factors were discussed by researching shear strength of the adhesive.The results indicated: the properties of epoxy silicone adhesive reach to top as the toughener approaches 25%,the toughener reacted with the curing agent perfectly,and the epoxy had a good compatibility with silicone.The strength of interfacial layer is intensified by the coupling agent which improves mechanical property of the epoxy silicone adhesive. |
