钢铁水基防锈剂的研制及其性能

为了研制一种环保、性能稳定、常温使用的钢铁水基防锈剂,以硅酸钠、丙烯基硫脲、三乙醇胺、聚马来酸酐、苯甲酸钠、甲基硅醇为原料,通过正交试验优化配方,并将优化配方的防锈剂对钢铁的防锈效果与市售403防锈剂和433防油剂进行比较.结果表明:优化的防锈剂配方及处理工艺为50.0g/L硅酸钠,l2.0g/L丙烯基硫脲,24.0g...

Preparation and Performance Evaluation of Water-Based Rust Inhibitor for Iron and Steel

Sodium silicate,allyl thiourea,triethanolamine,polymaleic anhydride,sodium benzoate and methyl silanol were used as the main raw materials to develop a kind of water-based rust inhibitor based on formulation optimization via orthogonal test.The rust-inhibition performance of resultant rust inhibitor for iron and steel was comparatively evaluated in relation to commercial rust-proof agent 403 and oil-proof agent 433.It was found that the optimum formulation of as-developed rust inhibitor was 50.0 g/L sodium silicate,12.0 g/L allyl thiourea,24.0 g/L sodium benzoate,10.0 mL/L polymaleic anhydride,40.0 mL/L triethanolamine and 300.0 mL/L methyl ailanol.The optimized processing conditions were suggested as pH value of 10,room temperature and filmformation time of 10 min.As-developed rust inhibitor possessed better performance than similar products in the markets.
