Background

In the field of furniture or wood doors, wood core materials are indispensable manufacturing materials in the field, and the most common wood core materials in the prior art are core materials mainly made of wood particle boards or shaving board materials and wood core materials made of laminated veneer lumber. In addition, the wood core material made of wood raw material is less and less, the reason is that the country limits the felling of forest resource, so that the wood raw material is less and less, the cost of the wood raw material product is high, and on the other hand, the production period is delayed due to the limited purchasing channel.

The core material made of wood particle board or particle board material has the disadvantages that the density of the core material made of the wood particle board or particle board material is low and far inferior to that of the wood core material made of wood raw material, and a large amount of chemical binder is adopted in the manufacturing process, so that the core material is not environment-friendly and is easy to deform.

The core material made of wood raw material has a disadvantage that the production area, growing environment, age of the log, etc. are uncontrollable, so that the passage of the core material made of wood raw material may cause mass quality defects in that the growing environment of the log, the log is affected by sunshine, and the length of the sunshine time of the log is determined by the density of the log. Since the density of the log is determined by the soil, the temperature, and the age of the log, the quality of the log cannot be controlled, and the log is distorted when applied to a material for manufacturing furniture or a wooden door.

With the continuous development of the technology in the field, in recent years, composite core materials mainly comprising engineering plastics, laminated veneer lumber and metal materials which are combined through chemical bonding agents appear on the market, and the composite core materials have the disadvantage that the chemical bonding agents can bond and combine the composite core materials due to different materials, but the component effect of the chemical bonding agents is reduced along with the time, so that the composite core materials are delaminated and separated, the composite core materials are distorted, deformed and curled, and furniture or wood doors are deformed. In addition, the secondary utilization rate of the composite material is low, and great expense is needed for classifying engineering plastics, laminated veneers and metals in the composite material.
