摘　　要：选用磷酸和氧化锌为主要原料,添加硝酸钠、柠檬酸、钼酸铵、亚硝酸钠和硫酸镍作为助剂改善防锈膜的成膜性能,研制了一种应用于铸铁烘缸的无机防锈液,通过正交实验得到防锈液最佳配方为:7 g·L-1氧化锌、24 ml·L-1磷酸、2 g·L-1硝酸钠、0.5 g·L-1柠檬酸、3.5 g·L-1钼酸铵、0.4 g·L-1亚硝酸钠、1.0 g·L-1硫酸镍。该防锈膜膜厚7.2μm,硫酸铜点滴时间大于44 s,在3%的氯化钠溶液中浸泡超过24 h后无锈点。Phosphoric acid and zinc oxide are used as the main material to improve properties of the anti-rust film. Sodium nitrate, citric acid, ammonium molybdate, sodium nitrate, nickel sulfate are added as additives. The inorganic anti-rust liquid is developed for the cast iron dryer. Through orthogonal experiments, the best formula of anti-rust liquid are as follows： 7 g·L^-1 of zinc oxide, 24 ml·L^- 1 of phosphate, 2 g·L^-1 of sodium nitrate, 0.5 g·L^-1 of citric acid, 3.5 g·L^-1 of ammonium molybdate, 0.4 g·L^-1 of sodium nitrite, and 1.0 g·L^-1 of nickel sulfate.The thickness of anti-rust film is 7.2 μm. Copper sulfate drop time is over 44 s, and the stainless dipping time in 3% NaCl solution is 24 hours.
