Abstract

The invention relates to a long-acting antimicrobial water-based environment-friendly paint and a preparation method thereof. A resin emulsion containing antimicrobial group is used as the main component of the base material of the paint, and the paint can have long-acting antimicrobial property without adding any other antimicrobial agent. The long-acting antimicrobial water-based environment-friendly paint is prepared from 25-40% of resin emulsion containing antimicrobial group, 5-35% of pigment or colorant, 15-30% of filler, 0.5-5% of wetting dispersant, 0.2-1.0% of neutralizer, 0.2-0.5% of defoaming agent, 0.2-0.5% of thickening rheological agent, 2-8% of film-forming assistant, 0-5% of antifreezing agent, 0-10% of functional assistant and 10-25% of deionized water. The long-acting antimicrobial water-based environment-friendly paint has a long-acting antimicrobial action, and also has the advantages of excellent water resistance, weather resistance, fouling resistance, scratch resistance, solvent resistance and high storage stability.

Description

technical field [0001] The invention relates to a durable antibacterial water-based environmental protection paint, which uses a resin emulsion containing antibacterial groups as the main component of the paint base material, and can make the paint have durable antibacterial properties without adding other antibacterial agents. Background technique [0002] Antibacterial coatings refer to a class of coatings that add antibacterial agents to make them have antibacterial properties. Because they can kill molds and bacteria such as Escherichia coli and Staphylococcus, they can improve the indoor environment and protect people's health. Its research and Apps get a lot of attention. Antibacterial agents can be divided into three categories: natural, organic, and inorganic: natural antibacterial agents include extracts such as chitosan and natural extracts. Natural antibacterial agents are mainly some extracts of natural plants. At the same time, natural antibacterial agents have...
