Abstract

The invention relates to a modified solvent-free acrylate dispersion, a preparation method of the modified solvent-free acrylate dispersion, a water-based coating, a preparation method of the water-based coating and a preparation method of colored sand. The dispersion does not contain a solvent, is small in molecular weight and good in permeability and wettability, improves the dyeing effect, reduces color difference, and enables dyeing to be firmer and more uniform. The sand prepared by the invention is good in dyeing property, weather resistance, water resistance and chemical resistance.

Description

technical field [0001] The invention relates to a modified solvent-free acrylate dispersion, a water-based paint, a preparation method thereof and a preparation method of colored sand. Background technique [0002] As an important "decorative seasoning", colorful sand is widely used in building materials such as real stone paint, epoxy flooring, relief, glass fiber asphalt tiles, and the demand is increasing year by year. However, the disorderly mining of natural colored stone resources has caused damage to the ecological environment. With the strict requirements of environmental protection policies on mineral sources, the supply of natural colored sand is becoming more and more limited. At the same time, because natural colored sand is directly broken from nature, most of it has chaotic color, poor strength, easy pulverization, and large batch color difference, which brings difficulties to production and use. Some natural colored sands with bright colors are small in quant...
