[0002] At present, the main materials of furniture on the market are density board, particle board, solid wood composite and the like, and the surface is generally treated by paint, baking paint and the like. Although there is a certain price advantage, many shortcomings are hidden, mainly as follows.

[0003] 1. Short service life. Most of the solid wood boards claimed on the market are multi-layer composite boards. Some merchants even use sawdust filling in the core and surface veneer in order to save cost. The quality of the materials cannot be truly distinguished by consumers, and the durability of the furniture cannot be guaranteed.

[0004] 2. Unqualified environmental protection. The materials used in the processes such as baking paint and transfer printing on the surface of traditional furniture materials are mostly chemical raw materials, and the content of formaldehyde, benzene and the like is difficult to meet the standard. Many raw material manufacturers even have no detection standard, and it is difficult to meet the standard in terms of health and environmental protection.
