Abstract

The invention discloses an antibacterial modified back paint, and belongs to the field of paints. The antibacterial modified back paint comprises 10-30 parts of polyester resin, 6-20 parts of a solvent, 0.1-1 part of a dispersant, 0.1-1 part of an anti-settling agent, 10-35 parts of rutile titanium dioxide, 2-10 parts of precipitated barium sulfate, 15-40 parts of an epoxy solution, 5-20 parts of semi-etherified amino resin, 1-5 parts of urea-formaldehyde resin, 1-5 parts of an adhesion promoter, 0.1-1.5 parts of an acid catalyst, 20-30 parts of common bluebeard herb, 10-20 parts of Japanese ardisia and 15-30 parts of Herb of Hairystalk Loosestrife. A paint film produced by using the antibacterial modified back paint has a hardness reaching 4-5H, good flexibility, T bending of 2-3T, and back flush of 9J. Extract products of common bluebeard herb, Japanese ardisia and Herb of Hairystalk Loosestrife can inhibit or kill most bacteria or viruses as antibacterial components, and have the advantages of good antibacterial effect and non-toxicity.

Description

technical field [0001] The invention relates to the field of paints, in particular to an antibacterial modified back paint. Background technique [0002] In various fields, paints are widely used, and as people pay more attention to health, the functionalization and environmental protection of paints are gradually accepted by the market. [0003] There are a large number of bacteria and virus microorganisms in the environment, which will not only affect human health, but also have a greater impact on the quality of the coating film formed by the paint. [0004] The existing commercially available antibacterial modified back paint uses antibacterial metal ions (silver ions, copper ions, etc.) Slowly permeate out of the medium, so that the entire surface is covered with positively charged metal ions. When the bacteria touch the surface, the negatively charged bacterial cells will attract the metal ions into the cell body, and closely combine with the negatively charged chemic...
