Problems solved by technology

However, due to the lack of special automatic mechanical processing equipment, most of the processes (such as breaking bamboo strips, weaving curtains and mats, etc.) are still in the manual production stage for a long time, and cannot form large-scale continuous production.

Abstract

The invention discloses a high-strength bamboo and oriented strand board composite board. The composite board is sequentially provided with an upper surface layer, an upper core layer, a middle core layer, a lower core layer and a lower surface layer from top to bottom, wherein the upper surface layer and the lower surface layer are made of bamboo chip shavings, the upper core layer and the lowercore layer are made of waste eucalyptus veneer shavings and the bamboo chip shavings, and the middle core layer is made of the waste eucalyptus veneer shavings; and the invention further provides a preparation method of the composite board, the preparation method comprises the following steps of raw material preparing, raw material drying, raw material screening, glue applying, laying, pressing and the like. According to the composite board, the bamboo and the waste eucalyptus veneers are adopted as the raw materials, so that wood resources are saved, the utilization path of the bamboo and thewood resources can be expanded, the composite board is high in strength, not prone to be deformed, safe and environment-friendly, and all performances of the composite board are superior to the performances of national standards; the composite board has excellent heat resistance, and has no obvious cracking condition under high-temperature, high-strength ultraviolet irradiation or long-time ultraviolet irradiation, so that the economic loss is reduced, and the composite board has a good application prospect.

Description

technical field [0001] The invention relates to the field of panels, in particular to a high-strength bamboo and oriented strand board composite panel and a preparation method thereof. Background technique [0002] OSB (Oriented Strandboard) board, also known as oriented strand board, has gradually replaced plywood and blockboard due to its good physical and mechanical properties and processing properties, and has become the main material for building decoration materials. At present, more and more buildings are decorated with oriented strand boards, and the proportion of construction is increasing. Not only home decoration ceilings, floors, wall decorations, wall kitchens, partition walls, etc. are made of oriented strand board materials, but even some high-end hotels, villas, Oriented strand board materials are also widely used in shops and other projects. With the improvement of urbanization and people's desire to improve living conditions, the application of oriented st...
