Problems solved by technology

However, conventional metallic paints have poor adhesion to plastic surfaces, and the surface needs to be pretreated to improve the adhesion strength of metallic paints. In addition, conventional metallic paints have poor scratch resistance and are easily damaged when used on the surface of outdoor equipment. Oxidation corrosion, causing the paint film to fall off, if not maintained regularly, the service life of the paint film is short

Abstract

The invention relates to the technical field of higher molecular coatings and particularly relates to metallic paint for protecting a plastic shell of electric equipment. The metallic paint contains the following components: acrylic acid and copolymer emulsion, chlorinated polyolefine, an emulsion, water, modified zinc chelate, nano-titanium dioxide, asilane coupling agent, pearlescent pigments, acuring modifying agent, a wetting dispersion aid, a light stabilizer, an ultraviolet light absorber, a defoaming agent and a film forming aid, wherein the curing modifying agent is cellulose acetatebutyrate or aliphatic hexamethylene diisocyanate; the pearlescent pigments are formed by mica particles coated with a titanium dioxide layer, and the particle sizes of the pearlescent pigments are 10-15 microns; and the film forming aid is propanediol butyl ether or propylene glycol methyl ether acetate. The metallic paint has strong adhesion force to the surface of plastic, is unlikely to fall, has good scratch resistance, corrosion resistance and aging resistance and is suitable for protecting the plastic shell of outdoor electric equipment.

Description

technical field [0001] The invention relates to the technical field of polymer coatings, in particular to a metallic paint used for the protection of plastic shells of electric equipment. Background technique [0002] Metallic paint is a kind of high-grade paint prepared with metal powder, such as copper powder, aluminum powder, etc. After reaching the aluminum particles, it is reflected by the aluminum particles through the paint film, which looks like the metal is shining, so it is called metallic paint. Metallic paint is suitable for the overlay protection of metal, wood, plastic, and building exterior walls, and can also be used for the overlay protection and decoration of epoxy, polyurethane, acrylic series and other paints. The paint film of metallic paint is tough, with strong UV resistance, corrosion resistance and high fullness, which can comprehensively improve the service life and self-cleaning property of the coating. [0003] Many electrical equipments are pro...
