Abstract

The invention discloses one-component salt fog resistant water paint and a preparation method thereof. The water paint includes the following raw materials in parts by weight: 20-46 parts of EPMC, 5-18 parts of special EPMC, 20-40 parts of anti-rust pigment, 13-30 parts of deionized water, 2-10 parts of an environment-friendly additive. The product is excellent in performance: the hardness is greater than or equal to H, the adhesive force is of 0-1 level, and the salt fog resistant duration is longer than 800 hours; the paint is environment-friendly and wide in application range.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a single-component salt spray-resistant water-based paint and a preparation method thereof. Background technique [0002] When the metal is exposed to the humid atmosphere, due to the activity of its surface, it has an adsorption effect on the polar moisture in the atmosphere, forming a layer of water film. When the water film layer reaches a certain thickness, it forms the necessary chemical corrosion a. Whether it is oxygen absorption corrosion or hydrogen evolution corrosion, because the anode area and the cathode area are in contact with each other, electrons move from the anode to the cathode under the action of the corrosion electric field force, and are absorbed by the nearby reducible medium, completing the electrochemical corrosion. . And because depolarizers such as oxygen and water are relatively abundant under atmospheric conditions, metal corrosion phenomena con...
