Problems solved by technology

The paint used on the exterior wall of the building is exposed to the air with the wind, sun and rain, and the dust is easy to adhere to the surface of the paint. After one or two years, the brand-new exterior wall paint will become dirty and inconvenient to clean. Beautiful can only be repainted, resulting in a great waste of resources
[0003] The anti-fouling effect of stain-resistant exterior wall coatings on the market is not very ideal. There is a fluorine-containing styrene-acrylic emulsion, which can improve the hydrophobicity, oleophobicity and compactness of the coating film, so that the coating film of the coating will not be stained during the drying process. It will be absorbed into the coating film with water, even if the coating film is stained, it is easy to remove the stain when washing, so that the coating film has high leveling and stain resistance; but due to the relatively high price of fluorine-containing monomers , and there are relatively few types, resulting in higher cost of fluorine-containing styrene-acrylic emulsion

Abstract

The invention discloses an architectural water-impermeable pollution-resistant paint and a preparation method thereof. The architectural brick is prepared from the following raw materials in parts by weight: 45-55 parts of ethylene-propylene emulsion, 10-20 parts of 107 glue, 6-12 parts of white cement, 1-3 parts of bentonite, 8-14 parts of titanium white, 10-14 parts of ground calcium carbonate, 1-3 parts of talcum powder, 1-3 parts of emulsifier, 2-4 parts of SN aid, 0.5-1.5 parts of defoaming agent, 2-4 parts of hydroxypropyl methacrylate and tritolyl phosphate in a weight ratio of (1-3):1, and 10-14 parts of water. The architectural water-impermeable pollution-resistant paint has the advantages of excellent water impermeability, excellent pollution resistance, low water absorptivity and low oil stain adhesive force. The external wall coated by the paint can not have the phenomenon of water permeation, and can not be easily polluted by oil stains, and the oil stains can be easily wiped off. Compared with the prior art, the architectural water-impermeable pollution-resistant paint disclosed by the invention has outstanding substantive characteristics and obvious progress.

Description

technical field [0001] The invention belongs to the field of construction, and relates to architectural coatings, in particular to a building anti-seepage and stain-resistant coating and a preparation method thereof. Background technique [0002] The development of new products of architectural coatings has always been a research hotspot for paint workers, and many scientific research units and enterprises are committed to the development of new functional architectural coatings. The paint used on the exterior wall of the building is exposed to the air with the wind, sun and rain, and the dust is easy to adhere to the surface of the paint. After one or two years, the brand-new exterior wall paint will become dirty and inconvenient to clean. Beautiful can only be repainted, resulting in a great waste of resources. [0003] The anti-fouling effect of stain-resistant exterior wall coatings on the market is not very ideal. There is a fluorine-containing styrene-acrylic emulsion...
