Novel nano antibacterial paint

Abstract

The invention discloses a novel nano antibacterial paint which comprises the following components in parts by weight: 25-35 parts of acrylic resin, 15-25 parts of polyurethane resin emulsion, 5-15 parts of titanium white, 2-8 parts of nano titanium dioxide, 3-9 parts of lauric acid, 4-12 parts of nano silver antimicrobial agent, 1-5 parts of curing agent, 3-8 parts of mildew preventive, 2-7 parts of leveling agent, 1-10 parts of film-forming assistant and 30-40 parts of solvent. The novel nano antibacterial paint has the advantages of excellent antibacterial property, high bacterial killing rate (up to 95% above), long acting time and long bactericidal effect. The novel nano antibacterial paint is free of formaldehyde, mercury and other heavy metals, has the advantages of no toxicity, no pollution, favorable water resistance, favorable weather resistance and high adhesive force, and is suitable for the field of decoration of external walls of hospitals, dwelling houses, schools and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel nano antibacterial coating. Background technique [0002] In the field of construction, the phenomenon that the surface of the exterior wall of the building is easy to be polluted and moldy and the surface of the wall is hydrolyzed and powdered is a new public relations task in the field of construction. Looking at the entire domestic coatings market, there are many varieties of exterior wall coatings, but most of them have protective and decorative functions. Antibacterial coating refers to the addition of antibacterial agents to the coating to make the coating have antibacterial properties. Natural antibacterial agents such as chitin, wasabi, etc. are easy to use, but their antibacterial effects are limited and cannot be broad-spectrum and long-lasting. Inorganic metal antibacterial agent, slowly released from the carrier, can effectively kill harmful bacteria attached to its ...

AI Technical Summary

Problems solved by technology

[0003] However, although the existing inorganic metal antibacterial coatings have antibacterial properties, the antibacterial time is short, and it is easy to be contaminated with dust, easy to absorb water and deteriorate, has low hardness and is easy to be damaged, easy to fall off, and has poor environmental performance.
