摘要
以端羧基聚醚复合环氧树脂 (CEF)为增韧改性剂 ,配合稀释剂、潜伏性固化剂、固化促进剂、填料等组分制得单组分环氧型车用折边胶CA - 8。组分含CEF 5 %～ 10 %、双氰胺 (Dicy) 5 %～ 7%、促进剂 0 .3%～1.5 %、填料 10 %～ 30 % ,制得的胶粘剂剪切强度 2 5MPa,剥离强度 5 5N·(2 5mm) -1,触变性。
The title one-component epoxy paste hemmed adhesive was prepared by flexible modifier CEF which was the adduct from CTPE and epoxy resin, diluents, latent curing agent, curing accelerator and fillers. The adhesive consists of 5%～10% CEF, 5%～7% Dicy, 0.3%～1.5% accelerator and 10%～30% fillers and has good thixotropy and storage stability,and its shear and peel strength are 25 MPa and 55 N·(25mm) -1 respectively.
