Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-insulating polyurethane wood varnish and a preparation method thereof. Background technique [0002] Wood paint refers to a type of resin paint used on wood products, including polyester and polyurethane paint, which can be divided into water-based and oil-based, and can be divided into high-gloss, semi-matte and matte according to gloss, and can be divided into furniture according to use. Lacquer and floor paint, etc. Natural wood lacquer is commonly known as lacquer, and it is also known as "national lacquer". The juice cut from the lacquer tree is called raw lacquer or original barrel lacquer, and the white cloth to filter out impurities is called raw lacquer. [0003] Polyurethane paint is polyurethane paint. It has strong paint film, full luster, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-grade wood furnitur...
