摘 要:以甲基乙烯基硅橡胶、苯基硅橡胶为原材料制备了高阻尼硅橡胶,研究了硫化工艺、胶粘剂以及偶联剂类型对胶料性能的影响。结果表明,最佳的一段硫化工艺为170℃×T_(c90),二段硫化工艺为220℃×4h;最佳的胶粘剂类型为胶粘剂Primer No.34T,剥离强度达到3MPa以上;最佳的偶联剂类型为γ-氨丙基三乙氧基硅烷,剥离强度达到4.5MPa以上,且破坏发生在橡胶基体内部。The high damping silicone rubber was prepared with methyl vinyl silicone rubber and phenyl silicone rubber,and the influences of vulcanization process,types of adhesives and coupling agents on properties of rubber were studied.The results showed that the comprehensive performance were optimum when the molding process was 170℃×tc90,the post vulcanization process was 220℃×4 h.The peel strength was above 3 MPa when the adhesive was Primer No.34 T.In addition,the peel strength was above 4.5 MPa and adhesion failure occurs inside the rubber matrix when the coupling agent was 3-aminopropyltriethoxysilane.
