Abstract

The invention discloses a spray lacquer. The spray lacquer is obtained by combining paint, an aerosol can, an aerosol valve, a propellant and stirring beads. The paint is prepared from, by weight, 22.0-35.0 parts of thermoplastic resin, 4.0-9.0 parts of metal powder, 0-2.0 parts of color paste, 2.0-9.0 parts of an adhesion promoter, 0.2-1.0 part of an anti-scratch flatting agent, 1.5-5.0 parts of an anti-scratch agent and 53.0-68.0 parts of a solvent. By the adoption of the technical scheme, the spray lacquer has the advantages that the spray lacquer is strong in electroplating effect, rich in color, good in corrosion resistance and capable of being covered with gloss oil, and the weather resistance and decorativeness of a lacquer film can be easily improved; the spray lacquer has good adhesion to a nonpolar substrate, and the lacquer film has excellent overall properties such as high hardness and good scratch resistance; the spray lacquer is high in solid content and does contain benzene solvents. The invention further discloses a preparation method of the spray lacquer.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a spray paint and a preparation method thereof. [0002] technical background [0003] Aerosol paint (also known as spray paint) usually consists of an aerosol can, an aerosol valve, content (paint) and a propellant, in addition to a stirring ball (glass bead) that is loaded into the aerosol can to help stir. As the main product in the aerosol industry, aerosol paint products have the advantages of flexible construction, flexible and convenient operation, rich and bright colors, excellent decorative effects, and excellent protection functions. They are widely used in metal, wood, glass, ABS plastics, etc. Coating of various substrates. [0004] Spray paint generally has the defects of low solid content and high VOC content. With the country's increasing emphasis on environmental protection and the collection of paint consumption tax, the solvent-based spray paint industry is facing a sev...
