室温快速固化高性能环氧树脂胶粘剂研究

摘要

为了提高胶粘剂在室温条件下的固化速度,并改善其力学性能,研究了固化剂含量、填料含量对环氧树脂胶粘剂固化速度和力学性能的影响.结果表明,当固化剂含量为95～100 phr,填料含量为60～ 80 phr时,胶粘剂的综合性能最好；该新型胶粘剂在室温12 min即可快速固化,剪切强度可达13.8 MPa,拉伸强度和弯曲强度分别达到了43.1MPa和83.2 MPa.%In order to improve the curing speed and mechanical property, the effect of curing and filler agent content on the mechanical property of the epoxy adhesive is investigated in this paper. The results show that when the curing agenl content is in the range of 95-100phr and the filler agent content is in the range of 60 - 80phr, the epoxy adhesive exhibits excellent synthetic properly. This new epoxy adhesive can be rapidly cured at the room temperature within 12 minutes. The values of its maximum shear strength, tensile strength and bending strength of the new epoxy adhesive are 13.8MPa, 43. IMPa and 83.2MPa respectively.
