以水溶性丙烯酸改性环氧树脂为成膜物质,通过添加有机改性铝钼正磷酸锌、防闪锈疏水化合物和其他助剂,制备出了水性铁红车间底漆。探讨了防锈颜料、p H调节剂、防闪锈剂和其他功能助剂的选用对漆膜性能的影响。结果表明:采用水溶性丙烯酸改性环氧树脂为成膜物质,以有机改性铝钼正磷酸锌和防闪锈疏水化合物复配使用为防锈体系,添加p H调节剂和其他功能助剂,可制备出综合性能优异、早期耐水性好、干燥速度快的水性铁红车间底漆,可满足铁路货车的使用要求。
Water-soluble acrylic modified epoxy resin as a film-forming material, by adding organic modified aluminum molybdenum orthophosphate, anti-rust rust hydrophobic compounds and other additives to prepare the water-based iron red shop primer. The effects of anti-rust pigment, p H regulator, anti-rust agent and other functional additives on the performance of the film were discussed. The results showed that water-soluble acrylic modified epoxy resin was used as the film-forming material, and the organic modified aluminum molybdate orthophosphate and the anti-rust rust hydrophobic compound were used as a rust-proofing system, pH regulator and other functional additives , Can be prepared with excellent overall performance, good early water resistance, fast drying water-based iron red shop primer to meet the requirements of the use of railway wagons.
