Waterborne antibacterial wood paint as well as preparation method and application thereof

Abstract

The invention discloses waterborne antibacterial wood paint as well as a preparation method and application thereof. The wood paint is prepared from the following components in parts by weight: 35 to50 parts of waterborne polyurethane dispersion resin emulsion, 5 to 10 parts of waterborne o-cresol formaldehyde epoxy resin emulsion, 0.5 to 2 parts of nanometer zinc oxide, 0.2 to 1 part of nanometer silver powder, 1 to 3 parts of isothiazolinone, 1 to 3 parts of nanometer silicon dioxide powder, 1 to 3 parts of a defoamer, 2 to 5 parts of a dispersing agent, 1 to 2 parts of a thickener, 0.5 to1.5 parts of a coalescing agent, 3 to 8 parts of an antifreezing agent, 2 to 4 parts of a preservative, and the balance of water. The waterborne antibacterial wood paint obtained with the preparationmethod not only solves the problem of poor abrasive resistance of waterborne wood paint, but also obviously enhances the shock resistance, water resistance and antibacterial performance, enhances thequality of the waterborne wood paint, and further has the advantage that the wood paint is poisonless, tasteless, pollution-free and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based antibacterial wood varnish and a preparation method and application thereof. Background technique [0002] At present, most of the wood paints on the market are oil-based paints, and the pollution problem of oil-based paints cannot be solved in the current society where environmental protection is the core. However, compared with oil-based wood paints, water-based wood paints not only have In addition to its role, it also has the characteristics of non-toxic, tasteless, and pollution-free. Therefore, today, when environmental protection issues are receiving much attention, water-based wood lacquers are more and more popular among people today. [0003] The performance of the emulsion has the greatest impact on the paint film of water-based wood paint. Since the film-forming mechanism of the water-based emulsion is very different from that of oil-based paint, the fi...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned problems, the present invention proposes a water-based antibacterial wood varnish and its preparation method and application, which can effectively make up for the shortcomings of the water-based wood lacquer's own poor wear resistance, and can not only significantly improve its impact resistance, water resistance, etc., It can also improve its antibacterial effect. The wood paint also has the advantages of non-toxic, tasteless, and pollution-free.
