【摘要】 试验了三乙醇胺对聚氨酯涂料在聚酯烘烤涂层表面上的层间附着力的增强作用，并考查了其对涂层性能的影响。结果表明，加入三乙醇胺的烘烤型聚酯中涂层表面，未经打磨就喷涂聚氨酯面漆，层间附着力完全达到要求，不会明显影响聚酯中涂层的物理机械性能更多还原

【Abstract】 The adhesive promotion of triethanolamine to polyurethane coatings on polyester baking coating surface, and its influences on the film performance were investigated It has shown that the polyurethane top coat can be sprayed on the baked polyester coatings containing triethanolamine without abrading, and has a good interlayer adhesions without compromi sing the physical properties of polyester intermediate coat obviously更多还原
