Environmentally-friendly and antibacterial mildew-proof nanometer coating

Abstract

The invention discloses an environmentally-friendly and antibacterial mildew-proof nanometer coating and a preparation method thereof. The environmentally-friendly and antibacterial mildew-proof nanometer coating provided by the invention comprises the following raw materials in parts by weight: 40-50 parts of an organic film-forming base material, 5-10 parts of a composite filling material, 1-3 parts of color masterbatch, 5-10 parts of a composite modified antibacterial agent, 1-3 parts of an antifoaming agent, 3-5 parts of a film-forming agent, 1-3 parts of a leveling agent, 3-5 parts of anorganic solvent and 1-3 parts of a pH regulator, with the balance being deionized water, wherein the composite modified antibacterial agent is composed of 60-70% of an organic antibacterial agent and30-40% of an inorganic antibacterial agent. The invention relates to the technical field of coatings. The environmentally-friendly and antibacterial mildew-proof nanometer coating provided by the invention has the following advantages: by adoption of the composite antibacterial agent, the composite antibacterial agent is dispersed into the coating base material in a nanometer manner, so the antibacterial effect of the coating is significantly improved; and through combined application of the inorganic antibacterial agent and the organic antibacterial agent, the purpose of strong antibacterialproperties, strong heat resistance and strong long-acting properties of the coating are achieved, so the antibacterial effect of the coating is further improved, and the coating is beneficial to use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly, antibacterial anti-mildew nano coating. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Auxiliary, a viscous liquid prepared with organic solvents or water. Coating is a material that can be coated on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. The organic components in paints such as latex paint, water-based paint and oil-based resin topcoat provide a rich material basis for the growth and reproduction of microorganisms. Microorganisms use these nutrients to undergo biodegradation, biochemical synthesis, metabolism in th...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an environmentally friendly, antibacterial and mildew-proof nano coating, which solves the problem that the antibacterial effect of the existing antibacterial coating is still poor. Although the use of organic antibacterial agents has a good bactericidal effect, it is heat-resistant Poor performance and long-term effect, and the antibacterial effect of inorganic antibacterial agents is not enough, it cannot be realized that the antibacterial effect of coatings can be significantly improved by using composite antibacterial agents and nano-dispersing the composite antibacterial agents in the coating base material. To achieve the problem of making the coating have strong antibacterial, strong heat resistance and strong long-term effect through the combined use of inorganic antibacterial agents and organic antibacterial agents
