Abstract

The invention discloses an external wall coating which is prepared from the following raw materials in parts by weight: 8-15 parts of mica powder, 20-40 parts of marbles, 3-10 parts of polyvinyl alcohol, 3-8 parts of acrylic resin, 0.2-0.4 part of lignocellulose, 1-5 parts of fibrous silicon ash powder, 10-30 parts of weight-calcium carbonate, 7-15 parts of asbestos fibers, 0.1-0.8 part of titanium dioxide, 1-3 parts of an anti-freezing agent and 50-100 parts of water. All the raw materials adopted by the external wall coating are natural minerals, so that the external wall coating is high in bonding strength and high in dynamic cracking resistance; the external wall coating has the characteristics of low expansion rate, high elastic viscosity, resistance to irradiation of ultraviolet rays, difficulty in cracking and falling, high acid and alkali resistance and long service life.

Description

Technical field [0001] The invention relates to a building decoration material, in particular to an exterior wall paint. Background technique [0002] Coating is one of the indispensable materials in the construction field. Its main function is to protect the surface of the building to make it waterproof, stain-resistant, heat-insulating or anti-ultraviolet. The higher-level exterior wall paint also has self-cleaning properties and stains. It's off as soon as it is flushed Existing architectural coatings generally contain film-forming emulsions (base materials), pigments, fillers, film-forming aids, defoamers, and water, etc. The fillers are mostly inert substances such as talc, which have poor acid and alkali resistance and waterproof performance. , And the paint will often crack and peel off due to poor adhesion after the construction is completed, it is impossible to protect the exterior wall of the building, and it is not beautiful. [0003] Most of the heat in buildings come...
