Abstract

The invention discloses a manufacturing method for a two-step-formed bamboo-based composite plate. The manufacturing method comprises the following steps: taking bamboo processing wastes or remainders as raw materials, processing the raw materials into bamboo shavings at first, and preparing a bamboo shaving plate blank with a certain strength from the bamboo shavings on the premise of ensuring no curing of an adhesive through drying, gluing, prepressing and other working procedures; and forming a composite plate blank by the bamboo shaving plate blank and one or more of a wood veneer, a bamboo skin, a plastic film (sheet), sticky membrane paper and other materials in a certain manner, and carrying out hot-pressing forming on the composite plate blank to obtain the two-step-formed bamboo-based composite artificial plate disclosed by the invention. According to the manufacturing method disclosed by the invention, the advantages of bamboo, wood, plastic, sticky membrane paper and other materials are adequately utilized, and a series of products with different applications can be obtained according to the different types of the used adhesives and materials, so as to meet many use requirements; and meanwhile, lots of bamboo processing wastes and remainders are adequately utilized, and good economic, social and ecological benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of composite wood-based board materials, in particular to a manufacturing method of secondary molding bamboo-based composite boards. Background technique [0002] my country is a country with relatively poor forest resources. Regardless of per capita forest area or timber stock volume, it is far below the world average level. However, my country is rich in bamboo resources. In terms of industrial utilization of bamboo, my country is at the advanced level in the world. At present, due to the tense contradiction between the supply and demand of wood, the development of the domestic bamboo industry is showing a rapid growth trend. There are more and more products using bamboo instead of wood, and the application fields are becoming wider and wider. With the rapid development of the bamboo industry, a large amount of waste and residues generated during the processing have become a serious ecological and environm...
