摘　　要：采用激活剂A和改性剂M ,制备了糠醛丙酮改性环氧胶粘剂 ,研究了它们对胶粘剂固化的影响及其对固结体压缩强度、应力 -应变关系的影响。制备的双组分GIC系列改性环氧树脂胶粘剂具有压缩强度高、良好的应力 -应变关系和弹性韧性。GIC胶粘剂起始粘度低 ,粘接力大 ,收缩率小于 2 % 。In this work a furfuralacetone modified epoxy adhesive was prepared by adding the activated agent A and modifier M, and the effects of them on the solidification,compressive strength and the stress-strain relationship of the adhesives were studied The serial GIC adhesives supplied with two components had high strength,good stress-strain relationship and elasticity,and they also had low initial viscosity,good adhesion force and the shrinkage ratio were less than 2 percent
