Problems solved by technology

[0005] In the dry powder coating of the pure rubber powder system, the performance of the coating depends largely on the rubber powder, but the difference in film formation between the redispersible rubber powder and the emulsion leads to the difference in the performance of the coating film, which is mainly manifested in the scrub resistance, aging resistance, etc., therefore, this type of coating has not been applied on a large scale

Abstract

The invention discloses a novel colorful dry powder coating. The novel colorful dry powder coating is prepared from, by weight, 400-500 parts of ordinary Portland cement, 200-300 parts of heavy calcium carbonate, 50-100 parts of talcum powder, 10-20 parts of titanium dioxide powder, 20-50 parts of iron oxide pigment, 2-3 parts of hydroxypropyl cellulose ether, 20-30 parts of modified redispersible polymer resin latex powder, 2-3 parts of sodium bentonite and 2-3 parts of ferrous sulfate. The colorful dry powder coating can be hardened under the condition of high humidity and rainfall, the adhesive power and washing resistant performance of a coating film are very excellent, the weatherability is good, and the novel colorful dry powder coating can be used for coating of internal and external wall veneers of new and old buildings.

Description

technical field [0001] The invention relates to a novel colored dry powder paint. Background technique [0002] Architectural coatings mainly refer to coatings used for building exterior walls, interior walls, ceilings, floors, etc., which have decorative, protective and residential performance improvement functions. At present, architectural coatings are mainly water-based coatings, and water-based coatings are coatings with water as the dispersion medium, including water emulsion and aqueous solution coatings. However, the composition of water-based paints includes up to 35% to 55% of water, which requires a lot of manpower, material and financial resources for the packaging and transportation of water-based paints; the shelf life and storage period of water-based paints are short. Resilience, that is, no stratification, thickening, etc. during storage, also requires high cost and specialized technology. [0003] Germany Wacker Chemical Company (WackerChemieAG) has devel...
