Abstract

The invention discloses high-stability solvent type plastic paint. The high-stability solvent type plastic paint is prepared from, by mass, 10-20% of acrylic resin, 55-60% of phenolic epoxy acrylic resin, 20-30% of organic solvent, 2-5% of polyurethane thickener, 2-5% of organobentonite, 5-10% of dispersant, 10-15% of stabilizer and 10-15% of vinisol cooh; the stabilizer comprises diglycidyl ether, calcium ricinoleate, barium oleate, phenyl triethyl phosphate, 2-hydroxy-4-methoxy-diphenyl ketone and a color retaining agent. A series of other additives high in stability are added and combined with the stabilizer mainly having the stabilizing effect to comprehensively improve the stability of the paint from the respects of light resistance, high temperature resistance, chemical corrosion resistance, sedimentary stability and anti-volatilization performance, it is ensured that the paint is high in flowability and adhesion property, and a film formed by the paint is high in strength, uniform in color and long in service life.

Description

technical field [0001] The invention relates to a plastic coating, in particular to a high-stability solvent-based plastic coating. Background technique [0002] Engineering plastics have developed rapidly in recent years, providing various industries with a wider range of choices for plastic substrates, and at the same time putting forward stricter requirements for plastic coatings. Traditional plastic coatings have a relatively narrow application area, are limited to one or two substrates, and have poor comprehensive performance. [0003] PVC, PE, PP, PS, ABS and other plastics will change color and reduce strength under the action of heat, light, oxygen and other factors. Unless the structure of the polymer itself is changed, this aging phenomenon cannot be prevented. Therefore, After coating, the coating itself has the properties of heat resistance, light resistance, and oxidation resistance; various coatings are composed of film-forming substances (various resins), sol...
