Abstract
The invention discloses a weather-proof mould-proof moisture-proof exterior wall paint which consists of the following components in parts by weight: 20-30 parts of ethanol amine, 5-10 parts of XG-95, 200-250 parts of nano kaolin, 250-300 parts of lithopone, 10-20 parts of starch, 500-600 parts of vinyl acetate homopolymer emulsion, 50-80 parts of propylene glycol, 30-50 parts of isopropyl alcohol, 250-300 parts of sericite, 150-200 parts of GR composite titanium dioxide pigment, 20-30 parts of aids and 250-300 parts of purified water. The weather-proof mould-proof moisture-proof exterior wall paint can resist environmental ultraviolet rays, the problems of color fading and gloss loss of the paint are solved, and the service life of the paint is prolonged; and meanwhile, the weather-proof mould-proof moisture-proof exterior wall paint has good stain resistance, rub resistance, powder resistance, weather resistance, mould resistance and moisture resistance.
Description
technical field [0001] The invention relates to the technical field of paint materials for exterior walls, in particular to a paint material for exterior walls with weather resistance, mildew resistance, corrosion resistance and moisture resistance. Background technique [0002] Exterior wall paint is a kind of paint used to paint the exterior of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration; exterior wall paint also requires water resistance, and requires Self-cleaning, the paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. [0003] Existing exterior wall paints are generally formulated with landscapes, pigments, film-forming aids, dispersants, defoamers, thickeners, wetting agents, fillers, antifreezes, etc. poor. In summer, due to strong ultraviolet radiation, the paint film is very prone to aging, loss of light, fading, discoloration, cracking, and...
