摘要

用底咬-主体胶胶粘刘体系胶接铝合金时底胶厚度对胶接强度特别是低温剥离强度有明显的影响。一般是底胶厚度超过一定值时,低温剥离强度明显下降.这种影响反映了底胶与主体胶的相容性.本文研究了底胶成分及其预固化程度和主体胶成分及其力学性能对底胶与主体胶相容性的衫响,并据此探讨了影响胶接性能对底胶厚度的敏感性的因素和降低体系的底胶厚度敏感性的途径.

Abstract

When primer adhesive system is used to bond aluminium alloys,primer thickness has obvious effects on the bonding strength,especially on low temperature peel strength.Generally,when primer thickness exceeds certain value,the low temperature peel strencth will decrease obviously.These effects reflect the compatibility of the primer and the adhesive.In this paper, the effccts of the chemical composition and degree of pre-curing of the primer and the composition and mechanical properties of the adhesive on the compatibility of the primer and the adhesive are studied and thereby the factors influencing the susceptibility of bonding strength on primer thickness and the wav of reducing the susceptibility of bonding strength on primer thickness are discussed
