Bamboo-wood composite board with high-strength bamboo plywood coated on the surface and manufacturing method thereof

Abstract

The invention relates to the technical field of composite boards, and in particular to a secondary-shaped bamboo-wood composite board, comprising a veneer layer, a bamboo plywood layer, and a bamboo curtain layer. The bamboo-wood composite board is characterized in that: the veneer layer includes a vertical-texture eucalyptus wood veneer, a horizontal-texture eucalyptus wood veneer or a vertical fir wood sheet; the bamboo plywood layer includes a second bamboo plywood layer or a third bamboo plywood layer; and the bamboo curtain layer includes a vertical bamboo curtain, a horizontal bamboo curtain or a bamboo mat. Wood in our country and from around the world, such as various coniferous wood and broad-leaved wood in natural forests and planted forests as well as bamboo, a resource with the advantages of fast growth, short cycle, being selectively cut every year and long time of sustainable utilization, can be effectively used. By using the materials compositely based on scientific design and reasonable combination, the problem of hardwood shortage around the world can be solved, and qualified passenger car floors, container floors, truck fences and the like can be mass produced.

Description

technical field

[0001] The invention relates to the technical field of composite boards, in particular to bamboo-wood composite boards subjected to secondary molding. Background technique

[0002] Due to the short growth period of fast-growing wood, fast-growing plantation wood generally has small diameters, many knots, loose and uneven materials, low strength, and large shrinkage. Large and deep cracks lead to unstable product quality and fail to give full play to the value of the material. Bamboo resources are the woody plants with the fastest growth rate, the easiest reproduction and the shortest maturity period on the earth. It has the characteristics of one successful afforestation, which can be selectively cut every year and used sustainably without damaging the ecological environment. In particular, among the bamboo resources in the world, the moso bamboo forests have the highest industrial utilization value and the best performance, and the moso bamboo forests that ...
