Water-in-water coating capable of being externally toned and application of water-in-water coating

Abstract

The invention relates to water-in-water coating capable of being externally toned and application of the water-in-water coating. The coating comprises basic paint, granulation liquid and a continuous phase; the basic paint comprises 56%-80% of water, 0.5%-1.2% of hydroxyethyl cellulose, 8%-20% of acrylate emulsion, 0.4%-20% of pigment filler, 0.24%-1.12% of magnesium lithium silicate-containing protective glue and 1.2%-8% of a first alkali swelling thickener; the granulation liquid comprises 90%-95% of water and 4.8%-10% of protective glue containing magnesium lithium silicate; and the continuous phase comprises 39.2%-69.2% of water, 30%-60% of an acrylate emulsion and 0.3%-0.8% of a second alkali swelling thickener. The preparation method of the coating comprises the following steps of: mixing the base paint and the granulation liquid according to a mass ratio of more than 2: 1 to prepare the colored particles with the particle size of less than 1mm; and mixing the colored particles and the continuous phase according to a mass ratio of (0.25-1.5): 1. The coating is proper in strength and can be externally toned.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-in-water coating capable of external coloring and application thereof. Background technique [0002] Water-in-water colorful paint, also known as liquid stone, is an all-water-based, one-time sprayed colorful granite paint, which produces vivid, durable and highly simulated colors. Compared with traditional real stone paint products, water-in-water colorful paint has the characteristics of low cost of ownership, low paint consumption during construction, easy transportation, and high raw material requirements. [0003] Although the water-in-water colorful paint has many excellent properties, its production is very troublesome. This is mainly because the water-insoluble flexible film on the surface of the color particles is difficult to control, so it can only color the basic paint and adjust the color of the color point in advance. , it is impossible to add additional color paste...

AI Technical Summary

Problems solved by technology

[0003] Although the water-in-water multi-color paint has many excellent properties, its production is very troublesome, mainly because the water-insoluble flexible film on the surface of the color particles is difficult to control, so it can only be mixed with the base paint, and the color of the color point is adjusted in advance. , it is impossible to add additional color paste to the finished product (external coloring), when the finished product is completed, there is no way to make any changes, so it is necessary to arrange a large number of coloring personnel to carefully operate, and the inventory pressure is high, and products of different colors need to be separated Packaging, batch colors, and color dot ratios vary greatly. Except for a few mainstream color numbers, they must be produced on-demand. The production efficiency is low and the production time span is long, which is not suitable for market requirements.
