Problems solved by technology

[0003] However, sand loss during spraying of real stone paint is an important factor limiting its development and application at present. This is mainly related to the thickness of aggregate particles and the consistency of paint. , and sand will fall during spraying, which will increase the cost; if the material particles are too fine, the paint surface will lack a concave-convex feeling, and the imitation stone effect will not be good, and the established effect will not be achieved

Abstract

The invention relates to the technical field of decoration materials for building exterior walls, in particular to a stone-like coating for an exterior wall. The stone-like coating comprises the following components in parts by weight: 25-50 parts of a silicone acrylic emulsion, 80-120 parts of aggregate, 15-20 parts of organic modified bentonite, 10-25 parts of hydroxyethyl cellulose, 0.5-1.5 parts of a wetting dispersant, 1-2 parts of anti-cracking resin, 1-4 parts of a coalescing agent, 0.5-0.8 part of a defoaming agent, 0.5-1.2 parts of a thickening agent, 0.5-1.5 parts of a mildew preventive, 0.5-3 parts of a pH regulator and a proper amount of water, wherein the aggregate is composed of natural colored sand and quartz sand according to a weight ratio of (1-3): (1-2), the particle size of the natural colored sand is 40-80 meshes, and the particle size of the quartz sand is 80-120 meshes. The invention also provides a preparation method of the stone-like coating. The stone-like coating prepared by the invention is smooth in spraying, clear in sand grains, high in hard drying speed, more layered in paint surface tone and better in stone-like effect, the weather resistance, acid and alkali resistance, color retention, water resistance and stain resistance of the exterior wall coating are enhanced, the comprehensive functionality of the exterior wall coating is improved, and the development and application of the exterior wall coating are facilitated.

Description

technical field [0001] The invention relates to the technical field of building exterior wall decoration materials, in particular to real stone paint for exterior walls and a preparation method thereof. Background technique [0002] Real stone paint is a kind of paint made of natural granite and other natural crushed stones through emulsion and adding various additives. The paint is water-soluble. Compared with traditional architectural coatings, real stone paint has wider environmental adaptability, can ensure good corrosion resistance of building exterior walls, can adapt to various harsh environments, and effectively prolongs the service life of buildings. Adhesion and freeze-thaw resistance make it widely used in exterior walls. Therefore, the analysis and research of real stone paint for exterior walls is of great significance. [0003] However, sand loss during spraying of real stone paint is an important factor limiting its development and application at present. Thi...
