A coating composition used for coating of a steel material and/or aluminum material comprises a corrosion inhibitor, a base resin and a curing agent. The corrosion inhibitor may be selected from cerium compounds, lanthanum compounds, molybdate salt compounds, gluconic acid derivative salts, porous base materials, triazole compounds, thiazole compounds, tetracyclines, and metal phosphate salt compounds of ascorbic acid. The base resin may include a xylene-formaldehyde-resin-modified amino-containing epoxy resins obtained by reacting an epoxy resin having an epoxy equivalent of from 180 to 2500 with a xylene formaldehyde resin and an amino-containing compound. The curing agent may be a blocked polyisocyanate compound obtained by blocking an isocyanate group of a polyisocyanate compound with a blocking agent.
用于涂覆钢材和/或铝材的涂料组合物包括一种防腐剂、一种基础树脂和一种固化剂。防腐剂可以选择自铈化合物、镧化合物、钼酸盐化合物、葡萄糖酸衍生盐、多孔基材料、三唑化合物、噻唑化合物、四环素和抗坏血酸金属磷酸盐化合物。基础树脂可以包括通过将具有180至2500环氧当量的环氧树脂与二甲苯甲醛树脂和含氨化合物反应而获得的二甲苯甲醛树脂改性的含氨基环氧树脂。固化剂可以是通过用阻滞剂阻滞聚异氰酸酯化合物的异氰酸酯基团而获得的阻滞聚异氰酸酯化合物。
