Abstract

The invention discloses high fire resistant waterborne polyurethane wood varnish, which is prepared from the following raw material components in parts by weight: 100 parts of waterborne polyurethane emulsion, 3 to 6 parts of N-methyl pyrrolidone, 5 to 12 parts of ethylene glycol butyl ether, 25 to 35 parts of deionized water, 1 to 5 parts of nano-silver, 2 to 5 parts of bamboo charcoal powder, 0.1 to 0.5 part of defoamer, 0.1 to 0.5 part of wetting agent, 0.5 to 2 parts of thickener, 5 to 13 parts of modified antimonous oxide, 2 to 5 parts of dipropyl aluminum hypophosphite, 1 to 5 parts of aluminum polyacrylate, 1 to 2.5 parts of 1,3-dihydroxyacetone and 2 to 5 parts of adipic acid dihydrazide. The high fire retardant waterborne polyurethane wood varnish provided by the invention is good in fire retardancy, strong in adhesive force, has excellent antibacterial property and can meet the operating requirement of the wood varnish.

Description

Technical field [0001] The invention relates to the technical field of wood paint, in particular to a high flame retardant waterborne polyurethane wood paint. Background technique [0002] Water-based wood paint is favored by people because it does not contain organic solvents, is safe, environmentally friendly, and healthy. It has been successfully developed and released to the market in large numbers to meet people's decoration and decoration needs. Among them, polyurethane waterborne wood paint has better corrosion resistance and aging resistance, and has been successfully used in coatings, textiles, clothing and other fields. However, because polyurethane paint film has the defects of fast burning speed and toxic gas generated during the combustion process, this has caused most of the existing polyurethane wood paints to have poor flame retardant performance during use, which limits the polyurethane water-based woodware. Application of lacquer. Summary of the invention [00...
