Abstract

The invention discloses waterborne hydrophobic oleophobic metal paint and a preparation method thereof, and belongs to the technical field of coatings. The waterborne hydrophobic oleophobic metal paint comprises 70-90 parts of base varnish, 3-6 parts of metal pigment, 2-5 parts of a cosolvent and 10-20 parts of waterborne self-made resin color paste. Through adjustment of the formula and use amount of the metal paint, the stability of the metal paint can be maintained when ordinary metal powder is adopted by the metal paint, and meanwhile the metal paint has the advantages of hydrophobicity and oleophobicity, removal of VOC and purification of the air.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based hydrophobic and oleophobic metallic paint and a preparation method thereof. Background technique [0002] Metallic paint, also known as metallic flash paint, has fine metal powder (such as aluminum powder, copper powder, pearl powder, etc.) added to its paint base. After the light hits the metal powder, it is reflected through the paint film. . Therefore, it looks as if the metal is shining. The main characteristics of metallic paint are: tough paint film, strong adhesion, strong anti-ultraviolet, corrosion resistance and high fullness, which can comprehensively improve the service life and self-cleaning property of the coating. The main application areas of metallic paint are the automobile industry, bicycle tricycle industry, various electromechanical casings, and household appliance casings. The surface sprayed with metallic paint can not only make the appearance look s...
