Using 3-（trimethoxysilyl）propyl methacrylate（KH570）and 2-hydroxypropyl methacrylate as raw materials and triethylamine as catalysts，we synthesized two modified polythiol curing agents P（SH）₃-Si and P（SH）₃-OH containing organic silicon units and hydroxypropyl ester units by click reaction，respectively. A series of high performance room temperature fast curingepoxy adhesives were prepared by using epoxy resin E51 as the main resin，2，4，6-tris（dimethylaminomethyl）phenol（DMP-30）as the promoter，and modified polythiol curing agents P（SH）₃-Si and P（SH）₃-OH as curing agent. The effects of addition of P（SH）₃-Si on the properties of adhesive gel time，viscosity，hardness，tensile strength，shear tensile strength，and water absorption were studied. The results showed that when the fraction of P（SH）₃-Si was 10%，the adhesive indicated excellent mechanical properties and good water resistance.
