Sand-in-sand multicolor paint and preparation method thereof

Abstract

The invention relates to a sand-in-sand type multicolor coating which is mainly prepared from protective glue, a color matching base material, a continuous phase, a pH regulator and a thickening agent, wherein the mass ratio of the protective glue to the color matching base material to the continuous phase is 10:(20-30):(60-70); the pH regulator accounts for 0.1% of the total mass of the protective glue, the toning base material and the continuous phase; and the thickening agent accounts for 0.3-0.5% of the total mass of the protective glue, the toning base material and the continuous phase. The color points prepared by the preparation method are high in toughness and strength, so that the color points are not greatly deformed during spraying due to mutual extrusion of muzzles, the sensitivity to spraying air pressure is reduced, and the color points can be directly sprayed under high air pressure; therefore, the spraying efficiency is improved, and moreover, the colored stone is not easy to break, the whole colored stone is clear, and the stone imitation effect is good.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a sand-in-sand type colorful coating and a preparation method thereof. Background technique [0002] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors, and it is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. The buildings decorated with real stone paint have natural and real natural color, which gives people elegant, harmonious and solemn aesthetic feeling. It is suitable for indoor and outdoor decoration of all kinds of buildings. Especially when it is decorated on curved buildings, it is vivid and lifelike, and has an effect of returning to nature. However, the color difference of its core raw material natural colored sand is serious, which affects the visual sensory effect of real stone paint, and real stone paint nee...

AI Technical Summary

Problems solved by technology

Water-in-sand multi-color paint can better imitate the color spots of various colors. The effect after spraying is uneven, which is closer to the surface effect of stone, but its spraying requires workers with rich experience, and the spraying air pressure must be strictly controlled during spraying. , if the air pressure is too small, the colored dots will not be easy to flatten, and the unevenness of the colored grains will increase, which will affect the imitation stone effect. At the same time, the consumption will increase. Difference

After water-in-sand spraying, there are generally fewer sand particles on the surface, and it has a stone texture, but there are still some differences in the imitation stone effect.
