Development of the Ahesive for Bonding PVC Decorating Film to Metal Sheets

叙述了一种单组份溶剂型聚氨酯胶粘剂的合成。选用高结晶度的聚酯、异氰酸酯、扩链剂等为原料，同时采用氯醋树脂增粘，应用于PVC彩色钢板生产流水线取得了满意的效果。

This paper discuss the synthesis of a one - component solution adhesive based on polyUrethane High crystallinity poyester, isocyanate and chain extender are selected to be as row material, and vinyl chiorideacetate copolymer is taken to increase viscosity. It is satisfactory to be applied to the prodution Line forPVC Laminating steel sheet.Keywoeds: Polyurethane adhesive Vinyl chloride - acetate copolymer PVC laminating steel sheet
