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.

Abstract

The invention relates to a sand-in-sand type multi-color coating, which is mainly prepared from a protective glue, a toning base material, a continuous phase, a pH regulator and a thickener. The quality of the protective glue, toning base material and continuous phase The ratio is 10:20-30:60-70; the pH adjuster is 1‰ of the total mass of the protective glue, toner base and continuous phase; the thickener is the protective glue, toner base and 3‰‑5‰ of the sum of the mass of the continuous phase; the toughness and strength of the color dots prepared by the sand-in-sand-type colorful paint preparation method of the present invention are high, so that the color dots will not occur due to the mutual extrusion process of the muzzle during spraying. Larger deformation reduces the sensitivity to spraying air pressure, so it can be sprayed directly with larger air pressure, which not only improves the spraying efficiency and reduces consumption, but also the colored stone is not easy to be broken, the overall clarity, and the imitation stone effect is good.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a sand-packed multi-colored coating and a preparation method thereof. Background technique [0002] Real stone paint is a kind of paint with decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors, and is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. Buildings decorated with real stone paint have natural and real natural color, giving people a sense of elegance, harmony and solemnity, and are suitable for indoor and outdoor decoration of various buildings. Especially the decoration on curved buildings is vivid and realistic, and has a return to nature effect. However, its core raw material, natural colored sand, has a serious color difference, which affects the visual sensory effect of real stone paint, and real stone paint needs to be matched with different colored sa...
