Problems solved by technology

However, the hydrophilicity of the alkali-swellable thickener makes the surface of the coating easy to absorb water, and water enters the color particles through osmosis. Due to the different water absorption rates of each component, the refractive index of light is different, resulting in the surface of the coating and the color particles. Particles will appear white
However, if two or more thickeners are used in combination, the negative effects of the thickeners will often be superimposed.

Abstract

The invention provides water-based colorful paint and a preparation method thereof. The water-based colorful paint is prepared from a dispersing phase, a protection glue solution and a continuous phase, wherein the continuous phase comprises a continuous phase A and a continuous phase B; the continuous phase A comprises an emulsion A with the reaction activity with the protection glue solution; the continuous phase B comprises an emulsion B without reaction activity with the protection glue solution; the mass ratio of the continuous phase A and the continuous phase B is 1:1-1:8. The water-based colorful paint has the advantages that the storage stability is high; the self thickening is realized; the viscosity is stable.

Description

technical field [0001] The invention belongs to the technical field of water-based multicolor paint, in particular to a water-based multicolor paint with self-thickening property and stable viscosity and a preparation method thereof. Background technique [0002] Water-based multi-color paint is a one-component paint for building exterior walls with two or more water-based color particles suspended in water-based media and produced by one spraying in a variety of colors imitating stone. Water-based colorful paint is composed of incompatible two-phase components, in which water-based color particles are the dispersed phase, the aqueous medium is a mixture of protective colloid solution and continuous phase, and the dispersed phase is usually a mixture of pigments, fillers, emulsions and gel systems, etc. It has certain strength, flexibility, contrast and anti-bleeding; the protective colloid aqueous solution is a homogeneous system formed by dissolving the protective colloid ...
