Abstract

The invention belongs to the field of manufacturing processes of composite artificial boards, and particularly relates to a production method for a whole bamboo or bamboo-wood composite veneer and a floor laminated board. The composite veneer and the floor laminated board comprise full bamboo, large bamboo sheets used for bamboo-wood composition and large wood sheets, and the large wood sheets are doped in the large bamboo sheets, drying is carried out after glue is applied, and a novel whole bamboo or bamboo-wood composite oriented strand board is pressed; then bonding and transverse saw changing are carried out to form the whole bamboo or bamboo-wood composite veneer and the floor laminated board. The whole bamboo or bamboo-wood composite veneer and the floor laminated board are not a simple LV1 board, and the LV1 board is changed into a novel product in a sawn manner in the longitudinal direction; the appearance is attractive in line, and the grade is higher; the adaptability to different parts made of bamboo species, wood, bamboo culms and wood culms is higher, the quality is stable, the strength is even, and the material variability is small; and the composite veneer and the floor laminated board are most ideal structure materials for replacing raw wood and bamboos, and have the beneficial effects of being high in raw material using rate and flat in board face.

Description

technical field [0001] The patent of the invention belongs to the field of composite wood-based panel manufacturing technology, in particular to a production method of all-bamboo or bamboo-wood composite veneer and floor veneer. Background technique [0002] Bamboo belongs to the Bamboo subfamily of Gramineae. China is very rich in bamboo resources. According to preliminary statistics, there are more than 400 species of 30 genera, which mainly grow in the provinces south of the Yangtze River Basin. The biggest feature of bamboo growth is that once afforestation is successful, bamboo shoots can be whipped out, cut down every year, and used sustainably without damaging the ecological environment, which is in line with the country's strategic thinking of replacing wood with bamboo. [0003] Many manufacturers at home and abroad choose bamboo to replace wood and develop bamboo oriented structural panels for various purposes. But most of existing bamboo oriented structure board...
