Embodiment 3

[0016] 9 parts of ethyl acrylate, 6 parts of heavy calcium carbonate, 10 parts of silicon dioxide, 11 parts of glycidyl butyl ether, 7 parts of dibutyl phthalate, 5 parts of terephthalic acid, 5 parts of acrylic resin, water 15 parts, calcined kaolin 3 parts, silane coupling agent 6 parts, 40-45nm ZnO 5 parts.

[0017] The application of the nano antibacterial and mildew-proof coating that the present invention proposes is: evenly coating the nano-antibacterial and mildew-proof coating on medical equipment, medical furniture, and the hospital indoor wall, so that the surfaces of these articles are covered by the coating, such as hospital beds and bedside tables , carts, desks, chairs, etc. When harmful microorganisms in the air or on human hands and other parts come into contact with these items, the harmful microorganisms remaining on these items will be captured and killed by the positively charged metal ions in the nano antibacterial and antifungal coating. Thus protecting...

Abstract

The invention discloses an antibacterial and mildew-resisting coating. The antibacterial and mildew-resisting coating is composed of the following materials in parts by mass: 9-10 parts of ethyl acrylate, 5-7 parts of ground calcium carbonate, 8-10 parts of silicon dioxide, 10-14 parts of butyl glycidyl ether, 6-8 parts of dibutyl phthalate, 4-6 parts of terephthalic acid, 4-5 parts of acrylic resin, 10-20 parts of water, 3-4 parts of roasted kaolin, 4-8 parts of a silane coupling agent and 3-7 parts of nano TiO2 and / or nano ZnO. According to the antibacterial and mildew-resisting coating, the nano TiO2 and / or nano ZnO are / is added and inorganic matters are used for realizing a long-time antibacterial function; the antibacterial and mildew-resisting coating is non-toxic and environmental friendly, is low in cost and is good for industrialization. The raw materials of the antibacterial and mildew-resisting coating are easily available and the antibacterial and mildew-resisting coating has very strong sterilization and mildew-resisting effect and has very strong waterproof performance. Whether a coated surface meets dried air or moist air, the antibacterial and mildew-resisting coating is not easy to strip off.

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...
