Antimicrobial water-based wood paint and preparation method thereof

Abstract

The invention discloses an antimicrobial water-based wood paint and a preparation method thereof. The antimicrobial water-based wood paint comprises the following components in parts by weight: 20-30 parts of epoxy acrylate resin, 10-20 parts of polyurethane resin emulsion, 5-15 parts of dimethylolpropionic acid, 2-8 parts of mercapto ethylene glycol, 3-9 parts of nano alumina, 6-12 parts of nano silver antimicrobial agent, 1-10 parts of nano filler, 2-7 parts of dispersing agent, 4-9 parts of defoaming agent, 1-5 parts of thickener and 30-40 parts of deionized water. The prepared antimicrobial water-based wood paint does not use any organic solvent, has the advantages of no toxicity and no pollution, and is nontoxic and harmless to the environment and human body. The antimicrobial water-based wood paint has favorable protein adsorption resistance and microbe adsorption resistance. The coating has the advantages of favorable adhesive force, favorable mechanical properties and favorable mold resistance. The antimicrobial water-based wood paint is suitable for the field of application of wood furniture, wood doors/windows and artificial boards.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to an antibacterial waterborne wood coating and a preparation method thereof. Background technique [0002] In our living environment, bacteria are always present and ubiquitous. The degree of harm to the human body by the presence of bacteria has been plagued and threatened everyone’s physical and mental health, such as Escherichia coli, Staphylococcus aureus, Candida albicans, and subtilis. Spores, etc., can cause bacterial infection to spread disease. [0003] Antibacterial wood coatings refer to the coatings used on wood products, including solid wood and wood-based panels. Antibacterial wood coatings are mainly furniture coatings, which not only give the wood and wood-based materials the desired aesthetic characteristics such as color and luster, but also protect the wood from damage caused by bacterial growth and biodegradation. [0004] However, the current domestic antibacterial wood coatin...

AI Technical Summary

Problems solved by technology

[0004] However, at present, domestic antibacterial wood coatings are basically solvent-based coatings, which have poor antibacterial persistence and are prone to drug resistance by microorganisms, are easy to degrade and are toxic, do not meet environmental protection requirements, and are highly toxic to the environment and the human body. Water-based wood coatings with strong antibacterial ability have very important practical significance
