摘　　要：通过对基料树脂种类、交联树脂种类、颜基比和催化剂种类的实验,研究各因素对棕色面漆的冲击性能的影响。实验结果表明,当基料树脂为C-19聚酯树脂、交联树脂为高甲醚化三聚氰胺树脂(Cymel303)、颜基比控制在(0.2~0.3)∶1、催化剂为封闭型酸催化剂A时,棕色面漆耐冲击性能达到最佳且综合性能不受影响。The effects of different base resin,curing agent,P/B ratio and catalyst on the impact performance of brown topcoat are investigated.The results show that the comprehensive performance of the Chocolate Brown(RAL8017)coil finish is not affected and the impact resistance was the best when the C-19 polyester resin is used as the base resin,the fully methyl etherified melamine resin(Cymel 303)is used as the curing agent,the P/B ratio is(0.2~0.3):1,and the block acidic catalyst A is used as the catalyst.
