Wood and bamboo composite shaving board and process

Abstract

The invention relates to a composite shaving board, which contains wood materials and bamboo skin materials and comprises a surface layer, an inner layer and an intermediate layer. The surface layer is made of long wood single plates, a shaving layer is laid in the intermediate layer, the long wood single plates of the surface layer are longitudinally arrayed in the grain direction, short bamboo skin layers or short wood single plate layers which are transversely arrayed are arranged on inner sides of the long wood single plates, namely the inner layer, and longitudinally arrayed long bamboo skin layers are laid on inner sides of the transversely arrayed short wood single plate layers. Manufacturing process of the wood and bamboo composite shaving board includes that the long wood single plates can be spliced or longitudinally arrayed along the grain direction; the short wood single plates or bamboo curtains are transversely arrayed by the aid of gluing; and then long bamboo curtains or bamboo mats are longitudinally arrayed on the short wood single plates or bamboo curtains along the grain direction. A wood and bamboo composite board with a three-layered structure is assembled, and the shaving board layer is manufactured, the wood and bamboo composite board is provided with the transversely arrayed short bamboo skin layers or wood single plate layers, transverse strength of the composite shaving board can be improved, transverse cracking of the board is prevented, transverse nail holding force is increased, and longitudinal static bending intensity of the board is enhanced.

Description

technical field [0001] The invention relates to the technical field of artificial boards, in particular to a composite particle board containing wood and bamboo strip materials and its technology. Background technique [0002] Today, in addition to steel, the world's load-bearing components in the construction and packaging industries still use the original original wood planks. With the rapid development of modernization, the demand for large-diameter timber has become increasingly prominent. The shortage of timber resources and the deterioration of the ecological environment have led to strict control of timber harvesting in various countries. Therefore seek a kind of new method, manufacture a kind of new product that can replace the wood that is in short supply day by day, promptly the research and development of wood composite particle board has very great significance undoubtedly. [0003] In the traditional production of particleboard, the branch wood of logs is gener...

AI Technical Summary

Problems solved by technology

Even OSB that can be used for packaging materials is difficult to meet the requirements of wood properties and cannot be used as a load-bearing component. Moreover, OSB has high material requirements, complex production process, and high manufacturing cost, so it is difficult to open up the market in China.

[0004] At present, most of the particleboards on the domestic market are made of wood scraps (or shavings), which are crushed, dried, glued, paved and pressed. These particle boards have low static bending strength and poor nail holding power. The length and strength of the particle boards cannot be used for large-scale outer packaging and construction projects with high requirements for weeks.
