摘　　要：使用硅烷偶联剂KH-550对钛合金表面进行预处理,研究了硅烷偶联剂预处理液浓度、钛合金热处理方式、橡胶硫化工艺对钛合金和丁腈橡胶粘接强度的影响。结果表明,使用硅烷偶联剂处理钛合金可以有效提高钛合金与丁腈橡胶的粘接强度。将钛合金在浓度为10%的硅烷预处理液中浸泡之后,于130℃下热处理1h,再与丁腈橡胶粘接,效果最好。The silane coupling agent KH-550 was used to pretreat the surface of titanium(Ti)alloy.The influence of the the concentration of silane coupling agent pretreatment solution,the heat treatment of Ti alloy and the rubber vulcanization process on the bonding performance of Ti alloy and NBR was studied.The experimental results shown that the bonding strength of Ti alloy and NBR can be effectively improved by treating titanium alloy with silane coupling agent.When theTi alloy was immersed in silane pretreatment solution with a concentration of 10%and followed with 130℃heat treatment for 1 h,the bonding strength of Ti alloy and NBR can achieve the best results.
