Abstract

The invention provides a new type of wood material, which is formed by laminating a composite core board and a reinforcing board. The raw materials of the composite core board and the parts by weight of each raw material are: mixed wood powder: 22-34 parts; wood fiber powder: 16-29 parts; alkali-free chopped glass fiber: 11-19 parts; HDPE: 4-9 parts; polybenzobisoxazole fibers 9-16 parts; basalt fiber: 16-23 parts; mannitol : 17-21 parts; 7-15 parts of silane coupling agent; Described mixed wood powder is the powder that the leftovers when poplar, eucalyptus, elm are manufactured products are ground respectively, and according to m poplar powder: m eucalyptus Wood powder: m elm powder=1:2:2 mixed to obtain, the particle size is 100-150 microns; the particle size of the basalt fiber is 120-160 microns; the polybenzobisoxazole fiber is powder Granules, the particle size is 500‑750um. The invention can have high strength, simple structure and long service life.

Description

technical field [0001] The invention relates to the technical field of wood, in particular to a novel wood material. Background technique [0002] Wood-plastic composite materials are composite materials made of wood or other cellulose materials and thermoplastics with uniform temperature matching. Although they have many advantages, there are still certain limitations and defects in the application of wood-plastic products in China. Wood-plastic products have defects such as insufficient mechanical strength, poor heat resistance, and large thermal expansion coefficient during use. When used as floor boards and other materials, the tribological properties of the material are not ideal. In order to improve the above limitations and make up for the defects, and expand the advantages of replacing wood products, the research and development of high-filling plant fibers and high-performance wood-plastic composite products will be the leading direction of enterprises and markets. ...
