摘　　要：论证了不同材料对水性涂料耐盐雾性能有着很大影响,如丙烯酸乳胶、聚氨酯乳液、有机硅树脂、云母粉及耐盐雾助剂的使用,均可以提高产品耐盐雾性。主要研究水性涂膜在盐雾箱中1080 h的表现,确认不同材料对耐盐雾性能的提升有如何影响,在此基础来改善汽车钢板或者电泳板材料耐腐蚀性能,并在常温固化的情况下满足产品其他所需性能。The experiment demonstrates that different materials have a great impact on the salt spray resistance,such as the use of acrylic latex,polyurethane emulsion,silicone resin,mica powder and salt spray resistance additives,which can improve the salt spray resistance of products.This paper mainly studies the 1080 h performance in a salt spray box and confirms how different materials influence the improvement of salt spray performance,and based on this,improve the corrosion resistance of automotive steel plates or electrophoretic plate materials,and meet other performance requirements of the product when cured at room temperature.
