Water-in-Water Paint and Its Application

Abstract

The invention relates to a water-in-water paint capable of external coloring and its application. The coating includes base paint, granulation liquid and continuous phase. The base paint includes: water 56%-80%, hydroxyethyl cellulose 0.5%-1.2%, acrylate emulsion 8%-20%, pigment and filler 0.4%- 20%, 0.24%-1.12% protective gel containing lithium magnesium silicate and 1.2%-8% of the first alkali swelling thickener; granulation liquid includes: water 90%-95% and protective gel containing lithium magnesium silicate 4.8%-10%; the continuous phase includes: water 39.2%-69.2%, acrylate emulsion 30%-60% and the second alkali-swellable thickener 0.3%-0.8%; the preparation method of the coating includes base paint and The granulation solution is mixed according to the mass ratio greater than 2:1 to prepare color particles with a particle size of less than 1mm, and the step of mixing the color particles and the continuous phase according to the mass ratio (0.25‑1.5):1. The coating has good strength and can be externally tinted.

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 its application. Background technique [0002] Water-in-water colorful paint, also known as liquid stone, is a fully water-based, one-time spraying colorful granite paint. The color produced is lifelike, durable and highly simulated. Compared with traditional real stone paint products, water-in-water multi-color paint has low cost of ownership, low paint consumption in construction, easy transportation, and high raw material requirements. [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 finishe...

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), and when the finished product is completed, there is no way to make any changes. Therefore, 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.
