Ultra-thin composite slice stone-like coating and preparation method and application thereof

Abstract

The invention relates to the technical field of coating for buildings, in particular to ultra-thin composite slice stone-like coating. The ultra-thin composite slice stone-like coating is prepared from the following components in parts by weight: 10-20 parts of ultra-thin composite slices, 20-30 parts of a pure acrylic emulsion, 15-25 parts of deionized water A, 15-22 parts of deionized water B, 15-25 parts of quartz sand, 0.1-0.3 part of a preservative, 0.5-2 parts of an antifreezing agent, 0.1-0.3 part of a defoamer, 0.5-2 parts of a coalescing agent, 0.08-1.0 part of an aluminum-magnesium silicate thixotropic lubricant, 0.05-0.1 part of multifunctional amine and 0.1-0.5 part of a thickener. The invention further provides a preparation method and application of the stone-like coating. The integration of the ultra-thin composite slices and the coating is improved, the problem of slice flying during construction of traditional slice stone-like coating is solved, construction is smooth,the fidelity of a coating film is improved, and the decoration effect is good.

Description

technical field [0001] The invention relates to the technical field of coatings for buildings, in particular to an ultra-thin composite rock flake real stone paint and its preparation method and application. Background technique [0002] Stone-like coatings are used to imitate the effect of exterior stone materials. Two or more water-based color particles are suspended in the water-based interlayer, and a single-component coating for the exterior walls of buildings can be produced in a variety of colors by one spraying. It is based on acrylic resin emulsion or elastic resin solution, and through the reasonable proportion and color matching of natural sand or artificial calcined colored sand, it is sprayed with a special spray gun to present a rich stone-like coating. [0003] The existing domestic imitation stone coatings are mainly real stone paint, water-in-water, water-in-sand and other products; water-in-water, water-in-sand and other products need to imitate each color ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, real stone paint mainly includes colored sand real stone paint and rock flake real stone paint; traditional rock flake real stone paint is to add hard rock flakes to the paint, and the hard rock flakes have good toughness and poor compatibility with paint, resulting in During the spraying construction, the specific gravity of the sand is different, so that the resistance to the rock flakes is large and flying flakes are easily produced; after the construction is completed, the rock flakes protrude from the surface of the coating, which has low fidelity, and the adhesion to the paint film is poor, and the firmness is low , resulting in rock flakes falling off from the paint film more easily, poor weather resistance and durability, and affecting the decorative effect
