AI Technical Summary

Technical Problem

Existing colored gold aerosol paint products have poor environmental performance, a noticeable pungent odor, uneven pigment dispersion, poor spraying performance, are prone to oxidation, and are prone to delamination during storage, affecting their decorative and protective effects.

Method used

A triple synergistic dispersion system is formed by star-shaped PEG polymer, alkyl bisphosphonate compound and macrocyclic oligopolyester. The star-shaped PEG polymer forms a three-dimensional spatial network inside the coating, the alkyl bisphosphonate compound forms chemical bonds with the metal surface, and the macrocyclic oligopolyester wraps the edges of the colored powder to improve dispersion uniformity and compatibility. Xylene and methyl ethyl ketone are selected as solvents to adjust the evaporation rate.

Benefits of technology

It improves the dispersion uniformity and compatibility of colored gold powder in resin, ensures the fluidity and storage stability of coating, achieves uniform atomization, enhances the metallic texture and brightness of coated objects, extends shelf life, and prevents oxidation and delamination.

Abstract

The invention relates to the technical field of paint spraying, and particularly discloses a mosaic gold aerosol paint and a preparation method thereof. The painted gold aerosol paint comprises the following raw materials in percentage by mass: 30-40% of acrylic resin, 20-30% of a solvent, 5-15% of painted gold powder, 0.5-1% of a dispersing agent, 30-40% of a propellant and 0.5-2% of other auxiliaries. The dispersing agent comprises a star-shaped PEG polymer, an alkyl diphosphonic acid compound and macrocyclic oligoester. The mosaic gold aerosol paint has the advantages of being capable of being stored for a long time and not prone to oxidation and layering, can present colorful metallic paint after being coated and has different metallic color effects at different angles, and the appearance aesthetic feeling of a coated object is remarkably improved.
