Problems solved by technology

Natural antibacterial agents are mainly chitosan, which has few varieties and poor durability. Organic antibacterial agents mainly include isothiazolinones, benzisothiazolinones, and organic amines. They have good antibacterial effects, but are harmful to the environment. Antibacterial agents are mainly silver-based antibacterial agents and substances with photocatalysis. Silver-based antibacterial agents have good antibacterial effects and durability, but their use is limited due to particle problems and the high price of silver ion antibacterial agents.

Abstract

The invention provides composite environmentally-friendly antibacterial paint and a preparation method thereof. The composite environmentally-friendly antibacterial paint comprises polyester modifiedorganosilicone resin, polypropylene grafted glycidyl acrylate, polyester modified acrylic resin, zirconium-containing composite silicate powder, cellulose acetate, nanometer zinc oxide powder, bamboofiber ultrafine powder, dibutyltin dilaurate, boiled tung oil, limonene, phthalic anhydride, a titanium dioxide suspension, methoxypropyl acetate, polyethylene wax, palm wax, nickel slag powder, pearlpowder, a leveling agent, a toughening agent, a defoaming agent, a coupling agent and a solvent. The composite environmentally-friendly antibacterial paint has the advantages of wide raw material source, low cost, low VOC content in paint construction and use, environmental friendliness, strong adhesion, weather resistance, pollution resistance, antibacterial property, low surface friction coefficient, scratch resistance, scrub resistance, long service life, and no problems such as foaming, cracking, whitening or even delamination after long-term use.

Description

Technical field [0001] The invention belongs to the field of paint, and specifically relates to a composite environmentally friendly antibacterial paint and a preparation method thereof. Background technique [0002] Paint is usually used to beautify and protect the substrate. The simplest paints are made of polymers in solvents, which are often referred to as paints. Paint can modify the appearance of the substrate by adding color, gloss or texture, and by harmonizing or distinguishing with the surrounding environment. [0003] In the coating process, traditional paints release a large amount of volatile organic compounds and have become one of the main sources of air pollution. On the one hand, it is the core element that causes smog. On the other hand, its own formaldehyde, benzene, heavy metals and other substances endanger the health of painters and product users. The paint sprayed on the surfaces of internal and external walls, wooden furniture, and metal appliances is in ...
