Abstract

The invention relates to the technical field of building coatings, and discloses a water-resistant fireproof thermal insulation coating for a building outer wall and a production process of the water-resistant fireproof thermal insulation coating. The water-resistant fireproof heat-insulation coating for the building external wall is prepared from the following components: lignocellulose, calcium formate, ash calcium powder, heavy calcium carbonate powder, cellulose ether, phosphate, aluminum silicate fibers, a chemical additive, deionized water, spherical hollow ceramic microbeads, an amino crosslinking agent and chitosan slow-release particles. After the spherical hollow ceramic microbeads are added, the spherical hollow ceramic microbeads have excellent high-temperature resistance and can reflect ultraviolet rays to achieve a certain ultraviolet-proof effect, so that when the coating is used for an outer wall, the ultraviolet rays can be effectively reflected, the condition that the coating is aged and falls off due to direct ultraviolet rays is avoided, and the service life of the coating is prolonged. The service life of the coating is longer.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to a water-resistant, fire-proof and heat-retaining coating for building exterior walls and a production process thereof. Background technique [0002] Exterior wall paint is used to paint the exterior walls of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Since 2013, energy-saving and environmentally friendly liquid stone water-based coatings have attracted more and more attention. Some exterior wall coatings also require water resistance and self-cleaning properties. The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. Exterior wall paint can be used for interior wall painting because it also has water resistance; while interior wall paint does not have anti-sun function, so interior wall paint cannot be used as exterior wall paint. [000...
