Solid wood composite plate of fiber reinforced structure and preparation method of solid wood composite plate

Abstract

The invention discloses a solid wood composite plate of a fiber reinforced structure and a preparation method of the solid wood composite plate. The solid wood composite plate comprises a face plate (1) and a bottom plate (2) which are overlaid up and down. A reinforcing layer (3) is arranged between the face plate (1) and the bottom plate (2). The face plate (1), the bottom plate (2) and the reinforcing layer (3) are adhesively connected through PUR glue. The preparation method comprises the first step of face plate material preparation, the second step of bottom plate preparation and the third step of pressing. Compared with the prior art, the formaldehyde-free production technology is adopted, the technology is simple, the rate of finished products is high, the solid wood composite plate is environmentally friendly and free of pollution, meets the requirement for healthy life and accords with the concept of environmental protection, the reinforcing structure is adopted, the plate performance is stable, the deformation coefficient is low, the composite plate with the large width size can be manufactured, and the solid wood composite plate can be used as a furniture material and a decoration material.

Description

technical field [0001] The invention belongs to the technical field of composite board production and processing, and in particular relates to a fiber-reinforced solid wood composite board and a preparation method thereof. Background technique [0002] The traditional solid wood composite panel manufacturing industry almost all adopts hot-pressing production process. In the production process, it not only consumes a lot of fossil fuels, but also produces a lot of carbon dioxide and PM2.5, which pollutes the environment and consumes a lot of energy. [0003] In the traditional composite panel manufacturing industry, whether it is a hot-pressing production process or a cold-pressing production process, the glue used contains more than 40% water. It is difficult to control the water absorption deformation of the material during the production process, resulting in poor product quality. Stable, poor yield. [0004] Traditional two-layer solid wood composite panels have defects ...

AI Technical Summary

Problems solved by technology

[0005] The two-layer solid wood composite board has different materials on the upper and lower layers, so the coefficient of contraction and expansion is also different, so there will be quality problems such as panel cracking, adhesive surface opening, and serious deformation during use.
