Abstract

The invention discloses a water-in-water multicolor coating as well as a preparation method of the coating. The water-in-water multicolor coating contains the following components in percentage by weight: 20%-22% of elastic polymer emulsion, 1%-2% of a protecting adhesive, 0.1%-0.5% of a crosslinking stabilizer, 0.1%-0.3% of a cationic crosslinking agent, 0.5%-1% of a film forming aid, 0.1%-0.8% of a thickening agent, 8%-10% of thermal insulation powder, 0.01%-0.1% of a wetting agent, 0.05%-0.2% of a dispersing agent, 1%-3% of infrared reflection pigment, 0.1%-0.5% of titanium dioxide, 1%-5% of kaolin, 0.3%-1.5% of other aids and the balance of deionized water. The water-in-water multicolor coating has the beneficial effects that a dispersoid is stable, and a coating layer has good weatherresistance, alkali resistance, durability and pollution tolerance and strong adhesive property and is colorful. According to the preparation method of the water-in-water multicolor coating, the stability of the prepared water-in-water multicolor coating can be effectively guaranteed.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-in-water multicolor coating and its preparation method and application. Background technique [0002] With the improvement of people's living standards, people's decorative effect of paint is getting higher and higher. At present, the decoration of building exterior walls is mainly based on real stone paint, ordinary colorful paint and exterior wall latex paint. The bold concept of colorful paint breaks the traditional single color, The decorative effect of flat coating creates a colorful and three-dimensional decorative surface, which is favored by consumers. The water-in-water multicolor coatings that are more popular in the market now have poor stability, that is, the colorful particles are fragile and tend to become smaller when the spraying pressure is high. And the shape of the particles changes, and there is also a short storage time. The particles will become smaller and b...
