Abstract

The invention provides a mould-proof antibacterial coating and a preparation method thereof, and belongs to the technical field of the coating preparation. The coating is prepared from the following raw materials in parts by weight: 100-150 parts of vinyl acetate emulsion, 50-100 parts of glycerol-phthalic resin, 6-10 parts of wetting dispersant, 20-40 parts of pigment, 20-30 parts of zeolite powder, 40-50 parts of diatomite, 20-30 parts of sepiolite powder, 4-6 parts of polyacrylamide, 5-10 parts of coalescing agent, 15-20 parts of microcapsule bactericide, and 2-4 parts of defoaming agent, wherein the microcapsule bactericide is prepared by taking organic modified bentonite as the capsule wall material, and the bactericidal activity ingredients Sichuan pepper essence oil and folium perillae essence oil as the core material. The microcapsule bactericide is added in the vinyl acetate emulsion system, the organic modified bentonite is used as the capsule wall material, and the slow release of the Sichuan pepper essence oil and the folium perillae essence oil is controlled so that the antibacterial effect is better and more durable.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of paint preparation, in particular to an anti-mildew and antibacterial paint and a preparation method thereof. [0003] 【Background technique】 [0004] Coating is a general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) on the surface of an object, including oil (based) paint, water-based paint, powder coating . Coatings are widely used in home improvement, shipbuilding, construction and many military industries and equipment, and are one of the necessary preparations / auxiliaries for the development of modern industry and agriculture. The anti-mildew and antibacterial properties of coatings are the key performances of coatings, which are directly related to the service life of coatings and coated objects. Once mildew occurs in coatings, it will make it difficult for ...
