Abstract

The invention belongs to the technical field of paint, and provides self-cleaning type stone-like paint. The self-cleaning type stone-like paint is prepared from the following components in parts by weight: 50-60 parts of natural colored sand, 50-60 parts of silicon-acrylic emulsions, 30-40 parts of deionized water, 20-25 parts of polyethylene glycol, 20-25 parts of diatomaceous earth, 10-15 partsof aminopropyl isobutylsilsesquioxane, 10-15 parts of calcium carbonate, 10-15 parts of polyvinylidene fluoride, 10-15 parts of zinc oxide, 5-10 parts of stearic acid, 3-5 parts of polymethyl methacrylate, 1-2 parts of adhesion aids, 1-2 parts of defoaming agents, 1-1.5 parts of coalescing agents and 0.7-1.3 parts of preservatives. A step-by-step mixing method is applied to preparation of the self-cleaning type stone-like paint. The self-cleaning type stone-like paint has the advantages that the technical problems of the paint in the prior art, such as proneness to peeling and cracking, longspray-drying time, low bonding strength and low durability, are solved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a self-cleaning stone imitation coating and a preparation method thereof. Background technique [0002] Architectural coatings have functions such as decoration and protection of buildings. Coating the surface of a substance can change its color, pattern, luster, texture, etc., improve the aesthetic value of the object, and protect the surface of the painted object from light, oxygen, and chemical substances from the outside. , solvents, etc., to improve the service life of the coated object. [0003] As a new type of paint, stone-like paint has been favored by people. Stone-like paint is widely used. Its decorative effect is comparable to stone, and it is more suitable for shaping various artistic shapes than stone. Stone-like coatings can be used as exterior walls, reliefs, beams and columns and other special-shaped wall decorations; it is also suitable for exterior wall painti...
