摘要： 以断裂力学方法研究了环氧树脂与玻璃的粘合及添加偶联剂的影响.测定了该粘合在80℃水中不同浸泡时间、不同偶联剂、不同偶联剂浓度和不同pH值的断裂能.利用Andrews普适断裂力学理论求得了破坏单位截面积界面上原子键合的界面能θo及水对θo的影响符合一级反应规律.比较了θo值与界面范得华相互作用能.推算出环氧树脂-玻璃粘合中至少有部分是主价键合.

Abstract: Adhesion of an epoxy resin to glass has been investigated by fracture mechanics test.Specimens were tested after various times of immersion in water at 80℃, and the adhesive failure energy 6 determined as a function of crack velocity. The effects of adding silane coupling agents to the epoxy resin, and the influence pH of water were studied.Using the generalized fracture mechanics theory, an intrinsic adhesive failure energy θ0 which is defined as the energy required to break interatomic bonds across unit area of the interface were separated from 9, The θ0 value of dry sample, 7.25Jm-2, is approximately 24 times the expected Van der waals interaction energy and this suggests that at least some of the bonds between epoxy resin and glass are primary.
