提高鞋用聚氨酯胶粘剂剥离强度的几种途径

Several methods of improving peeling strength of polyurethane adhesive for shoes

论述了提高聚氨酯胶粘剂剥离强度的几种途径。包括选择具有结晶度高、结晶速度快的原材料合成聚氨酯胶粘剂,通过改性或添加增粘树脂提高聚氨酯胶粘剂的结晶度和结晶速度。选择合适溶剂、表面处理剂和配合异氰酸酯固化剂使用等,来提高聚氨酯胶粘剂对材质的剥离强度。

This paper presented several methods of improving peeling strength of polyurethane adhesive. They included selecting the raw materials with highly crystallinity and fast speed of crystallization,increasing the speed of crystallization and crystallinity by blend modification and adding tackifying resins and using suitable solvents, surface treating agents and curing agents.
