摘　　要：通过试验分析了底漆干燥条件、腻子层厚度以及底漆层与腻子层的配套性对水性环氧底漆与不饱和聚酯腻子涂装体系层间附着力的影响。试验证明:当水性环氧底漆干膜厚度为55～65μm时,根据体系配套性恒温60℃烘干2～4h,自然干燥20～22 h,刮涂390～450μm腻子层,能够达到良好的层间附着力。The influence of drying condition of primer, thickness of putty layer and the compatibility of primer and putty layer on the adhesion between unsaturated polyester putty and waterborne epoxy primer was analyzed by experiments. The experimental results show that the coating system with a waterborne epoxy primer thickness of 55-65 μm and putty thickness of 390-450 μm will have an excellent adhesion by drying 2-4 h at 60℃ and natural drying for 20-22 h after painting the primer.
