摘　　要：对比讨论了在环氧胶粘剂中添加活性硅微粉和非活性硅微粉,对环氧胶粘剂在6种不同粘接界面(砂轮机打磨、砂纸打磨、喷砂机打磨、有机溶剂处理、高温灼烧和空白处理)及两种不同粘接环境(空气中和水下环境)的粘结强度的影响规律。综合讨论了硅微粉性质、粘接界面处理方式和粘接环境对环氧胶粘剂粘结强度的影响。结果表明,空气中固化的环氧结构胶实验中,油膜是影响环氧固化物钢-钢拉伸抗剪强度的主要因素;水下环境固化的环氧结构胶实验中,沟槽深度是影响其环氧固化物钢-钢拉伸抗剪强度的重要因素。The effects of the addition of active and inactive micro silicon powders to epoxy adhesives on the bonding strength of epoxy adhesives at six different bonding interfaces(grinded by grinding machine, grinded by sandpaper, grinded by sand blasting machine, treated with organic sol-vent, burned at high temperature and blank team) and in two different bonding environments(air or underwater) are compared. The effects of micro silicon powders’ properties, the treatment for bonding interface and the bonding environment on the bonding strength of epoxy adhesive are discussed.The results show that in the epoxy structural adhesive experiment in air, the oil film is the main factor which affects the tensile shear strength of steel-steel cured epoxy product. In the epoxy structural adhesive experiment in the underwater environment, the groove depth is an important factor which affects the tensile shear strength of steel-steel cured epoxy product.
