Waterborne wall surface antifouling paint

Abstract

The invention relates to waterborne wall surface antifouling paint. The paint is prepared from the following components in parentage by weight: 15 to 30 percent of a silver ion copolymer and polyurethane complex compound, 10 to 20 percent of a surfactant, 10 to 15 percent of titanium dioxide, 5 to 10 percent of a film-forming auxiliary agent, 2 to 5 percent of a thickening agent, 3 to 6 percent ofa de-foaming agent and the balance of water. The adopted silver ion copolymer and polyurethane complex compound has antibacterial and mildew-proof functions; the problem that an outer wall of a building has stains and spots can be solved to keep the outer wall of the building clean; the adopted surfactant has the effects of disinfecting and sterilizing; the adopted titanium dioxide can be used for improving the anti-ageing performance of a coating film, reflecting sunlight and keeping a wall surface bright for a long time; the adopted polyurethane thickening agent can be used for improving the stability, constructability and water resistance of a product; the adopted de-foaming agent can be used for improving the hydrophobicity, compactness, adhesion force and construction recoating performance of a product paint film.

Description

【Technical field】 [0001] The invention relates to the technical field of coatings, in particular to a water-based antifouling coating for walls. 【Background technique】 [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value rate. It not only has the function of preventing the surface of buildings, ships, machinery, etc. Strong fine chemical product. [0003] The exterior wall of the building is exposed to the outside for a long time, and it is easy to be eroded by nature and form stains. The traditional external wall cleaning method requires cleaners to clean at high altitude through the protective belt on the roof. Not only is the safety low and the cleaning cost is high, but also the use of cleaning tools such as brushes to scrub the wall surface will scratch the high-grade wall surface. The surface becomes rough and uneven; localized bright spots occur, and the paint film surface is inconsistent. [0...

AI Technical Summary

Problems solved by technology

The traditional external wall cleaning method requires cleaners to clean at high altitude through the protective belt on the roof. Not only is the safety low and the cleaning cost is high, but also the use of cleaning tools such as brushes to scrub the wall surface will scratch the high-grade wall surface. The surface becomes rough and uneven; localized bright spots occur, and the paint film surface is inconsistent

[0004] Anti-fouling has always been the main demand (or selling point) of interior wall coatings, but the anti-fouling and anti-erosion capabilities of general interior wall products are not very strong. Many stains are not easy to wipe off, and usually the paint film is wiped off powder or It is the paint film that is wiped bright and bright, and it is easy to find that it has been scrubbed

This is mainly because the paint film of general interior wall products is not dense enough, which makes the paint film easy to be stained and infiltrated and difficult to clean and wipe off. In addition, the hardness of the paint film of interior wall products is not high, and the product formula PVC (pigment volume concentration) is too high Due to the matte effect required by the paint film
