Abstract

The invention provides a preparation method of a water-based polyurethane anti-corrosive paint. The water-based polyurethane anti-corrosive paint is prepared from the following raw materials: water-based epoxy resin, polyurethane, dispersant, stabilizer, bactericide, defoaming agent, carbon black, zinc phosphate, barium sulfate, corrosion inhibitor, leveling agent, drying agent and thickening agent. The preparation method comprises the following steps: evenly stirring related raw materials according to the formula, and grinding with a sand mill until the fineness is 30-60 mu m; and while stirring, adding the residual polyurethane, stabilizer, binder, bactericide, leveling agent, drying agent and thickening agent, homogenizing, and filtering.

Description

technical field [0001] The present invention relates to the preparation method of anticorrosion paint, more specifically a kind of preparation method of waterborne polyurethane anticorrosion paint. Background technique [0002] The production of anti-corrosion paint is generally inseparable from organic solvents, which are easy to pollute the environment and have a certain impact on the human body. The smell of paint lasts for a long time. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a new preparation method for water-based polyurethane anti-corrosion paint. The anti-corrosion paint produced by this method has good storage stability, can be dried at room temperature or dried, and is convenient for construction , using water as a solvent, has little environmental pollution, high hardness of the paint film, scratch resistance, good three-proof performance, good salt spray resistance, exce...
