摘　　要：通过对自制环氧黏结剂不同配合比及不同温度下容留时间的研究,确定了最佳的促进剂配方;研究了自制环氧黏结剂在不同温度下养护不同时间的拉剪强度变化规律,确定了该材料满足钢桥面坑槽修补的技术要求和其在不同养护温度下强度变化的回归方程。Through research of shelter time under different mix ratio and different temperature, the paper determines the best accelerator polyesters. The rule of shear strength changing for this epoxy adhesive with different maintaining time under different temperature is studied, and in this paper the technical requirements of materials for repairing pothole of the steel deck and its regression equation of strength changing under different maintaining temperature are determined.

关 键 词：环氧黏结剂 配合比 拉剪强度 坑槽修补 回归方程
