摘要
选取水性饱和聚酯、水性交联剂以及无铬无铅颜填料,研制出具有一定防腐性能的环境友好型卷材涂料,并分析了前处理、防腐颜料、固化剂、助剂等因素对涂层性能的影响。所得底漆膜厚6～9μm,具有良好的机械性能,配合10～15μm面漆后的耐盐雾时间达360h。
An environment-friendly coil coating with certain anticorrosion performance was developed by using waterborne saturated polyester, waterborne crosslinking agent and Cr-and Pb-free pigments. The effects of pretreatment, anti-corrosive pigments, curing agent and additives on coating properties were discussed. The dried primer coating with a thickness of 6～9 μm has good mechanical properties and a salt spray resistance up to 360 h in conjunction with a 10～ 15 μm thick top coat.
