Water-based anti-bacterial mould-proof paint

Abstract

The invention discloses a water-based anti-bacterial mould-proof paint. The water-based anti-bacterial mould-proof paint is prepared from the following components in parts by weight: 25-35 parts of water, 4-5 parts of acrylic resin, 1-5 parts of propylene glycol, 3-8 parts of ethylene glycol, 5-15 parts of coloring material, 5-7 parts of heavy calcium carbonate, 8-10 parts of silicon dioxide, 3-4 parts of calcined kaolin, 8-15 parts of rutile type titanium dioxide, 1-3 parts of mould-proof bactericide, 2-4 parts of amine salt dispersant, 1-3 parts of polyether type antifoaming agent, 2-6 parts of silicon solvent and 28-34 parts of emulsion. Nano TiO2 and / or nano ZnO are / is added and a long-acting anti-bacterial function is achieved by using inorganic compounds; the surface of an article or a building coated with the paint cannot be eroded by microorganisms such as moulds and the like, so that the articles or the buildings are beautiful and durable for a long time; the product is non-poisonous, environment-friendly and low in production cost and facilitates industrialization; the raw materials are easily available, the paint has strong sterilization and mould-proof effects and strong waterproofness; and the paint cannot be peeled off no matter in dry air or moist air when coated on the surface.

Description

technical field [0001] The invention relates to an antibacterial and antimildew coating, which belongs to the technical field of coatings. Background technique [0002] Architectural latex coatings are widely used for their excellent film-forming properties and environmental friendliness, and are developing rapidly. Since the coating film of architectural latex coatings is not as dense as that of solvent-based architectural coatings, it is easily corroded by bacteria and microorganisms and mildew spots appear, which affects the appearance of buildings. [0003] The most effective way to improve the antibacterial and antifungal properties of architectural latex coatings is to add substances that have antibacterial and antifungal functions and can exist stably in the coating film to exert antibacterial effects. Traditional antibacterial and antifungal agents, such as formaldehyde, heavy metal salts, phenol, sodium pentachlorophenate, etc., have been banned due to their toxici...

Problems solved by technology

Silver-based antibacterial agents have good antibacterial effect and durability, but due to the problem of particle size and the high price of silver ion antibacterial agents, their application in coatings is limited

[0004] Anti-mold technology has been widely used in pharmaceutical factories, breweries, food processing workshops and other places, but it cannot meet the current requirements for anti-mold effect, and it cannot take into account the two functions of waterproof box and anti-mold. The existing anti-mold coating has a low service life. , high cost, low overall performance
