AI Technical Summary

Problems solved by technology

[0003] Water-in-water multicolor paint manufacturers in my country use different raw materials and production methods. Because many paint manufacturers do not fully grasp the properties of water-in-water multicolor paint, there are still some problems in product quality, especially for each batch. There are many unstable phenomena such as large color error of colored particles, poor granulation uniformity and consistency, poor spray uniformity, etc.
In addition, the existing domestic water-in-water coatings for exterior wall decoration can only imitate simple patterns such as granite, and it is difficult to do so for natural marble coatings with complex patterns and lines.
In order to achieve such an effect, it can only be achieved by dry-hanging marble slabs, which is costly and difficult to construct. Moreover, due to the heavy weight of marble slabs, it is easy to damage the EPS outer wall insulation layer or fall off easily, causing safety accidents

Abstract

The invention aims to provide a water in water colorful paint for a building outer wall and a preparation method thereof. The water in water colorful paint is widely used. The raw materials of the water in water colorful paint is prepared from protective glue powder, vinyl chloride-vinylidene chloride copolymerized emulsion, acrylic ester quaternary copolymerized emulsion, water-based fluorocarbonemulsion and the like. The paint can be used in multiple outer wall decoration surfaces, has high simulation quality, can show the natural marble effect, is low-cost, protects environment and saves energy, is easy to use, and has a long service life. Further, the preparation method for the paint has the advantages of ensuring stable quality of batches of paint and causing small difference.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a water-in-water multicolor paint used for building exterior walls. Background technique [0002] The academic name of water-in-water colorful paint is liquid stone. The common name in the general industry is water-in-water colorful paint. Water-based colorful paint is actually a dispersed water phase of water-based latex paint, which is a multi-phase suspension of the continuous phase composed of protective colloid solution. Water-based colorful paint is mainly composed of continuous phase or dispersed phase. The continuous phase has a low concentration of continuous phase and low viscosity of continuous phase; the dispersed phase has high concentration and high viscosity. [0003] Water-in-water multicolor paint manufacturers in my country use different raw materials and production methods. Because many paint manufacturers do not fully grasp the properties of wat...
