Water-based acrylic acid shining paint and preparation method thereof

Abstract

The invention relates to the technical field of water-based paint, in particular to water-based acrylic acid shining paint. The water-based acrylic acid shining paint is composed of, by weight, 90-95 parts of a component A and 5-10 parts of a component B; the component A comprises water-based hydroxy acrylic resin, BEK-760, water-based aluminium powder, an anti-settling agent, cosolvent, neutralizer, a CAB aqueous solution with the mass fraction being 30%, 2959 and the balance water; the component B comprises water dispersion type polyisocyanates. According to the water-based acrylic acid shining paint, a paint film is high in drying speed, metallic pigment is uniformly arranged, the paint film is uniform in color, and excellent adhesion is achieved. The photoinitiator 2959 is added to the paint, in the construction process, the paint is sprayed at the same time of being cured through illumination of an ultraviolet lamp, the paint film is high in drying speed, meanwhile, 2529 can further promote system volume shrinkage, arrangement of the aluminium powder is facilitated, thereby a good arrangement effect is achieved, and the paint film can be uniform in color.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based acrylic glitter paint and a preparation method thereof. Background technique [0002] Metal glitter paint is a kind of high decorative industrial paint. After construction, the paint film dries quickly, has good adhesion, bright colors, and presents a layered metallic glitter effect. It is widely used for coating various machinery, machine tools, precision instruments, medical devices, etc. However, traditional metallic glitter paints are all solvent-based paints, and the solvent content is greater than 650g / L, which causes great pollution to the environment during construction. Today, with the increasing calls for environmental protection and increasingly severe environmental laws and regulations, there is an urgent need to develop low-VOC, environmentally friendly water-based metallic glitter paints. [0003] The biggest advantage of water-based metall...

AI Technical Summary

Problems solved by technology

[0004] At present, the arrangement of metallic pigments or pearlescent pigments in water-based metallic glitter paint is poor. Due to the slow surface drying of water-based metallic paint, the arrangement of metallic pigments is easy to bloom, resulting in uneven color of the paint film.
