Steel surface treating agent and preparation method thereof
The invention discloses a steel surface treating agent and a preparation method thereof. The preparation method comprises the following steps: adding a rust remover, potassium chlorate, sodium chlorate, a corrosion inhibitor, a surfactant, zinc nitrate and peregal in deionized water, adding zinc oxide after mixing uniformly, and mixing uniformly again for standby application, wherein the raw materials in the steps in percentage by weight are as follows: 0.1-0.5% of zinc oxide, 0.1-1% of potassium chlorate, 10-40% of a rust remover, 1-5% of peregal, 0.1-2% of zinc nitrate, 0.5-10% of a corrosion inhibitor, 0.1-1% of sodium chlorate and 1-6% of a surfactant; the deionized water is added to 100%. The steel surface treating agent integrates the functions of oil removal, rust removal, oxide layer removal and phosphorization, is particularly suitable for the metals obtained after hot rolling process, and is simple in treating process, low in labor intensity, low in treating cost, remarkable in rust removal effect, long in holding time and pollution-free to environment.
