摘　　要：用溶液法合成了一种具有独特结构的单组分PU胶粘剂,考察了扩链剂、表面处理剂、固化剂及PU胶粘剂的分子量等对粘接性能的影响。结果表明,上述因素对胶粘剂的性能改善较大。The effects of factors such as chain lengthening agent,surface-treating agent and hardener on polyurethane adhesive properties were studied. The results showed that the initial bonding strength and the physics properties of polyurethane adhesives were improved obviously.
