摘　　要：以含环氧基酚基树脂(X)作为通用EP(环氧树脂)胶粘剂的改性剂,制备了低温抗结晶型EP粘钢胶,并着重探讨了X对粘钢胶的基本力学性能、耐温变性能、抗结晶性能和综合性能等影响。结果表明:X改性粘钢胶的基本力学性能随温度或龄期的增加而不断增大;当w(X)=20%或30%时,X改性粘钢胶具有良好的抗结晶性能和力学性能;通过调整配方,可配制出满足GB50367—2006标准(A级)的抗低温结晶型粘钢胶。With X（a resin with epoxy group and phenolic group） as modifier of universal EP（epoxy resin） adhesive,a low temperature crystallization resistance EP adhesive for steel was prepared,and the influences of X were emphatically investigated on basic mecllanics properties,temperature change resistance,crystallization resistance and combination property of adhesives for steel. The results showed that the basic mechanics properties of X modified adhesives for steel were increased with increasing temperature or euring age. The X modified adhesives for steel had good crystallization resistance and mechanics properties when mass fractions of X were 20% or 30%. A low temperature crystallization resistance EP adhesive tot steel was confected by adjusting formula,which could meet standard of GB 50367--2006（grade A）.
