Two ways of using 3-glycidoxy propyltrimethoxycilane and 3-aminopropyltriethoxysilane promoters for improving adhesion between epoxy adhesive compositions cured using anhydride and amine hardeners and D16AT aluminum alloy are considered. The work of adhesion and free surface energy of epoxy adhesive compositions with promoters are determined. The possible reactions of the promoters to the components of the adhesive compositions and a metal surface are studied. A probable mechanism of bonding epoxy adhesives and a substrate is proposed. It is shown that preliminary treatment of the aluminum alloy surface with an aqueous alcohol solution of a promoter is the most effective way to increase adhesive shear strength.

使用环氧-和氨基-烷氧基硅烷促进剂提高环氧粘合剂组合物与铝之间的粘合力

考虑了使用 3-环氧丙氧基丙基三甲氧基硅烷和 3-氨基丙基三乙氧基硅烷促进剂改善使用酸酐和胺固化剂固化的环氧粘合剂组合物与 D16AT 铝合金之间的粘合性的两种方法。测定具有促进剂的环氧粘合剂组合物的粘合功和自由表面能。研究了促进剂对粘合剂组合物的组分和金属表面的可能反应。提出了环氧树脂粘合剂和基材粘合的可能机制。结果表明，用促进剂的醇水溶液对铝合金表面进行预处理是提高粘接剪切强度最有效的方法。
