High-wear-resistant and high-weatherproof dry powder latex paint and preparation method thereof

Abstract

The invention belongs to the technical field of decorative materials, in particular, relates to a high-wear-resistant and high-weatherproof dry powder latex paint and a preparation method thereof, andsolves the problems of many bubbles, poor leveling property, difficult dispersion, poor wear resistance and poor weather resistance of a dry powder latex paint in the prior art. The high-wear-resistant and high-weatherproof dry powder latex paint includes the following raw materials: white cement, calcium carbonate, ash calcium powder, redispersible latex powder, sodium silicate, modified boron carbide, titanium dioxide, far infrared ceramic powder, wood fibers, aluminum dihydrogen phosphate, a bactericide, a silane coupling agent, and a defoamer. The prepared dry powder latex paint has the advantages of safety, environmental protection, zero VOC, stable and uniform performance, strong cohesiveness, high strength after a coating layer is formed, good leveling property, excellent wear resistance, aging resistance and corrosion resistance, fire prevention, flame retardancy, mildew prevention and bacterial resistance, is not easily discolored, has long service life, and can be widely applied in indoor and outdoor wall decoration.

Description

technical field

[0001] The invention relates to the technical field of decorative materials, in particular to a dry powder latex paint with high wear resistance and high weather resistance and a preparation method thereof. Background technique

[0002] Latex paint, also known as latex paint, is a kind of organic paint, which is prepared by adding pigments, fillers and various additives with synthetic resin as the base material. In recent years, my country's architectural coatings have developed rapidly, and product research and development are also developing in the direction of water-based, high solid content, and low VOC. As an important water-based paint variety, latex paint occupies an absolute share in the paint market, especially the home improvement market, due to its convenient use, easy color matching, and good water resistance. However, because it is a water-based dispersion system with a moisture content of more than 30%, it is not convenient for packaging, trans...
