Abstract
The invention discloses a preparation method for a steel surface treatment agent and belongs to the field of metal surface treatment. The method includes the steps that firstly, polysiloxane, sodium pyrophosphate, potassium sorbate and sodium dodecyl sulfate are acquired to be mixed, deionized water is added to a mixture, the mixture is stirred evenly and heated to be at the temperature of 50 DEG C under the stirring condition, and the temperature is kept for 20 min; secondly, a solution acquired in the first step is cooled to be at the temperature of 25 DEG C and polyurethane and aluminum oxide are added and stirred for 10 min; and thirdly, caffeic acid and zinc nitrate are added to a solution acquired in the second step and evenly stirred so that the steel surface treatment agent can be acquired. The steel surface treatment agent is used for treating the surface of steel, a dense protective film can be formed on the surface of the steel, the surface of the steel is effectively prevented from being corroded by the external environment, the anti-oxidation capacity and the anti-corrosion capacity of the steel are enhanced, the luster of the surface of the steel can still be maintained after the steel is placed in air for a long time, and the treatment agent is free of pollution to the environment, degradable, low in cost, safe in use and beneficial to utilization and popularization.
Description
Technical field
