[0002] At present, in the wood processing industry, mass-produced boards are loose in material, low in density, and poor in mechanical strength, and cannot be directly used as materials for furniture, interior decoration, etc.
Existing boards absorb water and easily swell, resulting in deformation and blistering of the boards. At the same time, there are problems such as poor water resistance, moisture resistance, corrosion resistance and fire resistance.
In addition, a large amount of formaldehyde-based adhesives need to be added in the production process of particleboard, so it is harmful to the environment and the human body, and the board made of wood is also prone to fire, and there are always hidden dangers in people's living environment.

Abstract
The invention relates to a lignin phenolic resin environment-friendly plate and belongs to the technical field of building materials. The environment-friendly plate comprises an upper coating, an upper plate, a middle coating, a lower plate and a lower coating sequentially arranged from top to bottom. The lignin phenolic resin environment-friendly plate is high in surface layer density, high in strength, less prone to deformation, simple in production process, high in production efficiency, definite in process parameter, high in operability and capable of directly serving as a material for furniture and indoor decoration, has the advantages of high anti-seismic performance, flame retardance, low smoke, nontoxicity, water resistance, moisture resistance, corrosion resistance, resistance to high temperature, insulativity, light weight, quickness in mounting, antiaging resistance and wear resistance and is pollution-free, safe, environment-friendly and long in service life, and artificial forest soft wood does not need to be treated in a sealed container.
