Novel high performance acrylic modified polyurethane water-borne wood paint

Abstract

The invention relates to the field of wood paint and in particular relates to novel high performance acrylic modified polyurethane water-borne wood paint. The wood paint is prepared from the following raw materials in parts by weight: 60-80 parts of Novel high performance acrylic modified polyurethane water-borne wood paint polyether waterborne polyurethane, 10-20 parts of a hexamethylene diisocyanate tripolymer, 10-30 parts of trihydroxyl methyl propane, 1-10 parts of n-butyltin dilaurate, 0.5-2.0 parts of sodium dodecyl sulfate, 1-5 parts of propylene glycol phenylate, 0.1-1.5 parts of polydimethylsiloxane, 0.3-1.6 parts of fluoro modified acrylate, 0.1-0.6 part of sodium hexametaphosphate, 0.1-0.3 part of a preservative, 0.2-0.8 part of an anti-ageing agent, 20-30 parts of water and a proper amount of a PH regulator. Besides excellent environmental protection and safety properties, the water-borne wood paint prepared by the method provided by the invention also has the advantages of moderate price, high adhesive force, relatively high coating hardness, corrosion resistance, solvent resistance, water resistance, capability of being quickly dried and good glossiness, and meets the market demand.

Description

technical field [0001] The invention relates to the field of wood lacquer, in particular to a novel high-performance acrylic modified polyurethane water-based wood varnish. Background technique [0002] Wood lacquer is a functional chemical product that is most closely related to people's daily life. With the continuous improvement of material living standards, people's requirements for lacquer are no longer limited to its beauty and protection for furniture, but also pay more attention to its impact on the living environment. and health effects. [0003] Compared with water-based paints, traditional oil-based paints have advantages in many aspects, such as fast drying of the coating and good film hardness, etc. However, as a product that uses organic solvents as dispersion media or diluents, from production to application, construction, There are great safety and environmental protection risks in storage. In the production process of paint, a large amount of low-boiling v...

AI Technical Summary

Problems solved by technology

[0004] At present, the water-based paints on the market are generally divided into three categories. One is acrylic acid as the main component. The polyurethane water-based paint has several times the wear resistance of oil-based paint. It is a high-end product in water-based paint, but the production process is difficult and the price is too expensive, which is difficult for ordinary consumers to accept.
