Low-temperature-resistant protective paint formula for castings for high-speed train

The invention discloses a low-temperature-resistant protective paint formula for castings for a high-speed train. The low-temperature-resistant protective paint formula is prepared from emulsion, ironoxide red, methyl isobutyl ketone, triethanolamine, aluminum dihydrogen phosphate, lignosulfonate, alkyl modified organosiloxane, acrylic resin urethane copolymer resin and polyacrylamide. The low-temperature-resistant protective paint formula can effectively protect high-speed train castings and effectively prolong the service lives of the castings, and is high in low-temperature resistance. 本发明公开了种高铁用铸件耐低温防护漆配方，包括乳液、氧化铁红、甲基异丁基甲酮、三乙醇胺、三聚磷酸二氢铝、木质素磺酸盐、烷基改性有机硅氧烷、丙烯酸树脂聚氨酯共聚树脂和聚丙烯酰胺。本发明能够有效的保护高铁铸件，有效的延长铸件的使用寿命,耐低温性能好。
