Self-crosslinking water-borne wood paint emulsion and synthetic method thereof

Abstract

The invention provides a self-crosslinking water-borne wood paint emulsion and a synthetic method thereof, relating to the technical field of coatings. The self-crosslinking water-borne wood paint emulsion contains the following raw materials in percentage by weight: 25%-60% of an acrylic emulsion, 2%-6% of isophorone diisocyanate, 2%-7% of glyceryl triacetate, 10%-45% of acrylic monomers, 20%-50%of a waterborne polyurethane resin emulsion, 0.2%-2% of an emulsifying agent, 3%-6% of nano-crystalline cellulose, 0.2%-1.5% of a defoaming agent and the balance of deionized water. By taking the self-crosslinking acrylic emulsion as a main raw material and utilizing the self-crosslinking acrylic monomers, isophorone diisocyanate, the waterborne polyurethane resin emulsion, glyceryl triacetate and nano-crystalline cellulose and other raw materials, the prepared self-crosslinking water-borne wood paint emulsion has relatively high crosslinking density, the hardness, boiling water resistance, solvent resistance, light remaining property, color remaining property and impact resistance of a coating film are relatively excellent, and the content of volatile organic compounds is low, so that the environmental pollution is avoided, and the human healthy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-crosslinking water-based wood paint emulsion and a synthesis method thereof. Background technique [0002] Wood coatings are an important part of the coatings industry. They refer to coatings used for equipment prepared from raw materials such as solid wood panels, wood grain panels, bakelite boards, and fiberboards. They are mainly suitable for furniture, floors, stationery, musical instruments, and building decoration materials. . At present, water-based polyurethane coatings that combine high performance and low VOC content can effectively control the composition and structure of coatings due to the cutting properties of polyurethane molecules, combined with new synthesis and cross-linking technologies, so that they have good low-temperature film-forming properties , high temperature resistance, high strength, wear resistance, environmental protection, etc., so it has...

AI Technical Summary

Problems solved by technology

The water-based wood coatings developed by these single water-based resins cannot meet people's requirements for high quality

[0004] Therefore, compared with the traditional solvent-based polyurethane coatings, a large amount of organic solvents are required in the synthesis process, resulting in high content of volatile organic compounds (VOC) in the product, which is easy to cause environmental pollution and endanger human health. can cause a fire hazard
