Aqueous metal paints preparation and paints therefrom

Abstract

A process for preparing metallic water paint includes such steps as proportionally mixing deionized water, acrylate, potassium salt of acrylic copolymer, hydroxyethyl carboxylate cellulose, nano SiO2, metallic water flashing powder, organic silica oil, ZH-10 and anti-mildew bactericiding agent, stirring, proportionally adding BCS, propanediol, thicking agent, alkoxide 12 and pH regulator, and stirring. Its advantages are rich colors, strong metallic feeling, high weatherability, durability and resistance to pollution and brush, and no environmental pollution.

Description

technical field

[0001] The invention relates to a preparation method of water-based metallic paint and the prepared water-based metallic paint, which is an environment-friendly wall paint. Background technique

[0002] At present, the wall paint used for exterior walls includes latex paint and solvent-based metal paint. The traditional latex paint for exterior walls is made of acrylate emulsion. This latex paint has the following disadvantages:

[0003] (1) The durability of weather resistance is poor, about 5-8 years;

[0004] (2) The stain resistance is poor. After one year of painting on the exterior wall, the surface of the paint film is covered with dust, and after being washed by rainwater, there are many streaks on the surface. Even if it is washed manually, there are 20% The traces left behind are difficult to remove, which affects the appearance of the exterior wall;

[0005] (3) No metallic luster, poor gloss retention.

[0006] The disadvantages of solvent-base...
