摘　　要：为了使水性硅橡胶具有实用价值,本文采用定性测试的方法,较系统地对有机锡催化体系室温硫化(RTV)水性硅橡胶粘接性进行了研究。结果表明,水性硅橡胶的粘接性随体系pH值的升高而提高;在一定范围内,水性硅橡胶的粘接性随催化剂用量或交联剂用量的减少而得到改善;加入适当的增黏剂、羟基稳定剂、或使用潜伏性活性基团的底涂剂都有助于改善水性硅橡胶的粘接性。Adhesion to different substrates of RTV water-based silicone rubber prepared with organotin as catalyst was investigated systematically by qualitative test.The results showed that the adhesion to substrates of water-based silicone rubber can be improved as the increase of pH value of silicone latex,or as the decrease of catalyst dosage or crosslinker dosage within certain range.In addition, the addition of proper adhesion promoter, hydroxyl-containing stabilizer,or the use of primer containing latently active group can all improve the adhesion to substrates of water-based silicone rubber.
