Problems solved by technology

serious pollution to the environment
[0004] At present, in many fields, especially the automotive field, the demand for metallic paint is increasing, and the existing metallic paints contain harmful solvents, which cause great damage to the body of the workshop staff.
In addition, the existing metallic paints are not flexible enough, so that the force of a slight scratch or bump is enough to damage the paint surface, making it extra delicate.

Abstract

The invention relates to water-based paint coated on a metal surface. The water-based paint is prepared from, by weight, 15-60 parts of water-based resin, 0.1-5 parts of neutralizing agent, 0.1-10 parts of dispersing agent, 0.01-5 parts of anti-foaming agent, 10-30 parts of extender pigment, 1-10 parts of coloring pigment, 1-10 parts of anti-rust pigment, 0.1-5 parts of thickening agent, 0.1-5 parts of base material wetting agent, 25-40 parts of deionized water solvent, 5-8 parts of ethylene bis-stearamide, 10-12 parts of bauxite, 5-8 parts of silicone acrylic emulsion, 2-4 parts of surface control agent, 0-2 parts of ph controlling agent and 0.1-5 parts of other auxiliaries, wherein the water-based resin adopts water-based alkyd resin or water-based epoxy ester resin or water-based acrylic resin or water-based phosphate ester resin. The water-based paint does not contain organic solvent and is resistant to corrosion, excellent in impact resistance and friendly to environment.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a water-based paint coated on a metal surface. Background technique [0002] Existing coatings (or paints) refer to a class of film-forming substances that can dry and form a film when applied to the surface of an object, making the object beautiful and protected, or forming a film with special functions on the surface of the object. [0003] There are many kinds of coatings produced in my country, especially the oily coatings that use organic solvents such as xylene as solvents for coating metal surfaces, which are generally called paints. During the production and use of paints, air pollution is very serious. The use of one ton of paint emits about 400-700 kilograms of solvent into the atmosphere, or even more. Great pollution to the environment. [0004] At present, in many fields, especially the automotive field, the demand for metallic paint is increasing, and the existing ...
