Abstract

The invention relates to high-adhesive force hydrophobic flame-retardant odor-removal PE piano wood lacquer. The PE piano wood lacquer is characterized by being prepared from hydrophobic organic fluorine boron with good adhesive force and excellent flame-retardant effect and epoxy modified unsaturated polyester resin, unsaturated polyester is synthesized by the steps of preparing by virtue of a solvent method and carrying out vacuumizing and recycling, the molecular weight and performance of resin are relatively uniform, and the theoretical solid content of the resin is 100%; and the wood lacquer is not added with an organic solvent which does not participate in curing reaction and has an odor removal effect.

Description

technical field [0001] The invention relates to a wood varnish, in particular to a high-adhesion hydrophobic, flame-retardant and odor-free PE piano wood varnish, which belongs to the technical field of coatings. technical background [0002] my country is the world's largest producer of wood and wood products, and is currently the largest exporter of furniture (mainly wooden furniture) in the world. It consumes a large amount of furniture coatings every year (among them, wooden furniture coatings are often called "wooden coatings") or "wood finish"). At present, the most widely used furniture coatings in China are mainly polyurethane paints, nitro paints, alkyd paints, and unsaturated polyester paints. [0003] Unsaturated polyester resin is the most commonly used type of thermosetting resin. It is a linear polymer formed by polycondensation of saturated dibasic acid, unsaturated dibasic acid and dibasic alcohol. It is formed by diluting cross-linking monomers or active sol...
