摘　　要：介绍了一种家电板用底面合一面漆的制备过程,分析了底面合一面漆及其涂装的优缺点,并对影响底面合一面漆漆膜物理机械性能和耐腐蚀性能的因素进行了探讨。通过各种条件试验,对配方进行优化,研究了基料树脂、固化剂、防锈填料、酸催化剂对底面合一面漆综合性能的影响。通过各项性能测试发现,主体树脂中聚酯和交联氨基树脂的比例以及催化剂的用量较大程度地影响了底面合一涂料的物性;当选用Tg为19℃、相对分子质量为8000、羟值为18~24的聚酯树脂作为基料树脂,并以Cymel 303为固化剂、钙离子交换型换二氧化硅CS311为环保型防锈填料、DNNSA为酸催化剂时,该底面合一面漆综合性能较好,可达到客户实际使用要求。The preparation,the advantages and disadvantages of the primer-topcoat integrated coatings for household appliance board are described.The factors affecting the physical-mechanical and corrosion resistance properties,such as the binder,cross-linker,anti-rust filler and acid catalyst,are discussed.The results show that the amino ratio and the amount of acid catalyst have more influence on the physical properties of the coatings.The comprehensive properties of the primer-topcoat integrated coatings are excellent and can meet the actual usage requirements of customers when the binder is polyester with its Tg 19℃,relative molecular weight 8000 and hydroxyl value from 18 to 24,meanwhile,Cymel-303 is used as curing agent and DNNSA is used as acid catalyst,and the calcium ion exchange type silica CS311 is used as anti-rust pigment.
