Problems solved by technology

This patent uses modified fluorocarbon emulsion and pure acrylic emulsion as film-formers, which belong to organic coatings and have the self-cleaning and antifouling properties of organic coatings, but do not have the anti-cracking, super-adhesive, and non-easy properties of inorganic coatings. Powdering, not easy to generate static electricity, long service life and other excellent characteristics; in addition, the patent uses antibacterial additives and antifungal agents to make the coating antifungal, and does not take slow release measures

Abstract

The invention relates to the technical field of coatings, in particular to an organic-inorganic antibacterial antifouling interior wall coating and a preparation method thereof. The coating is prepared from an inorganic hybrid perfluorocarbon modified acrylate self-emulsifying emulsion, zeolite-loaded silver, silica gel-loaded silver, a functional filler, calcined kaolin, wollastonite powder, ash calcium powder, a Taieasy HD-20 dispersing agent, a Taieasy inorganic powder DS-195 dispersing agent, 2, 4, 7, 9-tetramethyl-5-decyne-4, 7-diol and deionized water. The inorganic hybrid perfluorocarbon modified acrylate self-emulsifying emulsion is used as a base material, and zeolite-loaded silver and silica gel-loaded silver are used as a composite inorganic mildew preventive, so that the coating has the characteristics of chemical corrosion resistance, flame retardance, fire prevention and environmental protection of an inorganic coating and the advantages of strong adhesive force and good scrubbing resistance of an organic coating; the coating is safe and non-toxic, excellent in mildew-proof performance and long in mildew-proof validity period.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an organic-inorganic antibacterial and antifouling interior wall coating and a preparation method thereof. Background technique [0002] In recent years, with the high-level development of my country's economy, people's quality of life has improved significantly, and people have paid more and more attention to a safe, healthy and comfortable indoor environment. Interior wall coatings have been recognized by the public due to their advantages such as convenient construction and environmental friendliness. With the refinement of coating functions, more and more people have higher requirements for interior wall coatings: [0003] One is environmental friendliness. At the present stage, my country has entered a critical period of providing more high-quality ecological products to meet the people's growing needs for a beautiful ecological environment. It is imperative to develop an...
