Contamination-resisting nanometer coating material of exterior wall of building

Abstract

The invention belongs to the technical field of building material decoration and specifically relates to a contamination-resisting nanometer coating material of an exterior wall of a building. The contamination-resisting nanometer coating material of the exterior wall of the building is prepared from the following raw materials in parts by weight: 1-10 parts of vinyl acetate-crylic acid copolymer emulsion, 30-50 parts of ethylene glycol, 10-20 parts of sodium pyrophosphate, 1-5 parts of hydroxyethyl cellulose, 200-300 parts of nanometer titanium dioxide, 100-300 parts of nanometer aluminum oxide, 5-10 parts of bactericide, 4-8 parts of dispersing agent, 3-5 parts of mildew preventives, 12-22 parts of PH value modifier, 120-150 parts of light calcium carbonate, 100-120 parts of talcum powder, 300-400 parts of water, 15-35 parts of sodium silicate and 10-30 parts of antioxidant.

Description

technical field [0001] The invention belongs to the technical field of building material decoration, and more specifically relates to a stain-resistant nanometer building exterior wall paint. Background technique [0002] With the improvement of people's living standards, people's pursuit of quality of life is also increasing, real estate developers are also paying more and more attention to the quality of real estate, and the requirements for building exterior wall decoration materials are also getting higher and higher, which has led to many new types The rise of building exterior wall decoration materials. At present, the building exterior wall decoration materials on the market mainly include: exterior wall coatings, exterior wall bricks, stone materials, aluminum panels, glass curtain walls, etc. Among them, exterior wall coatings and exterior wall bricks are more common in residential real estate. However, the cost of exterior wall bricks and the initial investment in...

Problems solved by technology

The exterior wall coating is exposed to the natural environment for a long time, and it has to withstand the effects of wind, sun, salt spray corrosion, rain, cold and heat changes, etc. Under the long-term repeated action of these external natural environments, the coating is prone to cracking, powder At the same time, due to the large amount of dust and other suspended substances in the atmosphere, the easily stained coating will lose its original decorative effect, thus affecting the appearance of the building. , and is often washed by rainwater

Therefore, exterior wall coatings are required to have good weather resistance, stain resistance, water resistance, etc., and at the same time, they must be safe, environmentally friendly, and durable, but the exterior wall coatings currently on the market cannot meet this requirement
