AI Technical Summary

Problems solved by technology

However, the effect of inorganic antifungal agents is poor, and many additives need to be added, and the processing cost is high; organic antifungal agents will age and decompose, resulting in a decline in the antifungal effect and affecting the film-forming properties of the coating.

Abstract

The invention discloses mildew proof water-based paint. The mildew proof water-based paint is composed of, by weight, 30-35% of silicone acrylic emulsion, 10-13% of composite filler, 6-8% of a mildew proof agent and the balance water in a mixing mode. According to the mildew proof water-based paint, the used raw materials enables the paint to have excellent adhesion performance and fire resistance performance and also can improve the mildew proof performance of a system, the ratio of all components is reasonable, compatibility is strong, and the obtained paint has long storage period, and is environmentally friendly and capable of being used in the fields like building decoration.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a mold-proof water-based coating. Background technique [0002] Coatings are a mixture of polymer substances and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that adheres firmly and continuously. [0003] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. The biggest difference between water-based coatings and solvent-based coatings is that most of the organic solvents in the coatings are replaced by water, which is composed of water, organic matter, fillers, etc. Water-based coatings are the development trend of the architectural decoration industry. They have the following characteristics: use water as a solvent, save resources, reduce the risk of fire during construction, and reduce air pollution; Good adaptability; spraying tools can be cleaned with water; simple const...
