Abstract

The invention relates to wood lacquer, and particularly relates to environment-friendly wood lacquer and a preparation method thereof. The environment-friendly wood lacquer comprises a primer and a finish paint, wherein the finish paint is prepared from the following raw materials: acrylic resin, an active monomer, a photoinitiator, a dispersing agent, a defoaming agent, a flatting agent and matting powder; and the primer is prepared from the following raw materials: acrylic resin, an active monomer, a photoinitiator, a dispersing agent, a defoaming agent, a flatting agent and pigment filler. The wood lacquer disclosed by the invention has good hardness and adhesive force, and the lacquer surface after coating construction has good appearance.

Description

technical field [0001] The invention relates to a wood varnish, in particular to an environment-friendly wood varnish and a preparation method thereof. Background technique [0002] With the development and progress of society, people's awareness of environmental protection has gradually increased. Countries have formulated some environmental protection regulations to limit the harmful compounds (VOC) in coatings, such as the national standard GB1851-2009 "Interior decorative materials, solvent-based wood Limits of Hazardous Substances in Coatings” puts forward clear requirements for the limit of VOC in wood coatings. Compared with solvent-based wood coatings, water-based wood coatings have lower VOCs. [0003] UV paint is ultraviolet photocurable paint, also known as photoinitiated paint and photocured paint. It is automatically rolled and showered onto the surface of the furniture board by machinery and equipment. Under the irradiation of ultraviolet light, the initiator ...
