The invention discloses a
rust transfer agent. The
rust transfer agent is prepared from the following raw materials in percentage by weight: 10-20% of RC-50, 0.1-0.5% of gaseous SiO2, 20-30% of precipitated
barium sulphate, 40-60% of H2O2 (S), 0.01-0.03% of waterborne defoaming agent and 5-15% of deionized water, or 8-18% of RC-50, 0.3-1% of gaseous SiO2, 20-30% of precipitated
barium sulphate, 40-50% of H2O2, 0.01-0.03% of waterborne defoaming agent and 15-25% of deionized water. The preparation method comprises the following steps of firstly, adding the metered deionized water, RC-50 and H2O2 (S) into a vessel, and uniformly stirring by using a high-speed dispersion
machine; adding the waterborne defoaming agent, and uniformly stirring; and adding gaseous SiO2 and precipitated
barium sulphate, and uniformly stirring to obtain the waterborne
rust transfer agent. The rust transfer agent is favorable in rust removal and prevention performances, good in film forming property, environment-friendly, simple in construction process and low in cost; and in addition, the rust transfer agent can be formed into an
inert metal complex together with
metal oxide and can form a protective layer on the surface of
metal, so that the salt spray resistance property of a product is greatly improved. The rust transfer agent can be used for replacing
pickling,
sand blasting and a manual method to remove rust and is environment-friendly, nontoxic, harmless, free of
pollution and convenient to use.
