Problems solved by technology

However, the raw material utilization rate of wood rotary-cut veneer and bamboo curtain and bamboo mat is very low. The yield of wood rotary-cut veneer is only about 60%, and the yield of bamboo curtain and bamboo mat plywood is even lower than 50%.
Regardless of whether it is unit processing or plate making, the processing technology is relatively complicated, labor-intensive, and the quality controllability is not high

Abstract

The invention relates to a composite structure plate of recombination bamboo wood and a medium-density fiberboard and a manufacture method thereof. The composite structure plate is composed of at least one layer of recombination bamboo wood and at least one layer of medium density fiberboard, and the thickness of the composite structure plate is 7-90 mm. The manufacture method includes the following steps: coating weather resistance glue on the recombination bamboo wood and the medium-density fiberboard, and coating the weather resistant glue on a contact face or coating the weather resistance glue on one lateral surface of the contact face; assembling the recombination bamboo wood and the medium-density fiberboard with the weather resistance glue to obtain a plate blank; and cold pressing, maintaining pressure, relieving pressure and preserving the plate blank to obtain the composite structure plate of the recombination bamboo wood and the medium-density fiberboard. The composite structure plate has good structure performance and is capable of conducting continuous production, simple in process, high in production efficiency, stable and reliable in product performance, remarkable in cost advantage, energy-saving, environment-friendly and suitable for various use purposes.

Description

technical field [0001] The invention relates to a novel composite structural panel for structure and a manufacturing method thereof, in particular to a composite structural panel of recombined bamboo and medium-density fiberboard and a manufacturing method thereof, belonging to the technical field of wood-based panel manufacturing in the wood / bamboo industry. Background technique [0002] As a characteristic and advantageous resource in my country, bamboo has the characteristics of high strength and good toughness. It has always been considered as an ideal structural material and has been widely used, such as bamboo plywood for car floor and building formwork. However, due to the lack of dedicated automatic mechanical processing equipment, most of the processes (such as breaking bamboo strips, weaving curtains and mats, etc.) still remain in the manual production stage for a long time, and cannot form large-scale continuous production. The development of recombined bamboo pr...
