Bamboo-wood composite board using low amount of adhesive and preparation process thereof

Abstract

The invention discloses a bamboo-wood composite board using a low amount of adhesive, the bamboo-wood composite board sequentially comprises an upper surface layer board, an upper reinforcing layer board, a composite core layer board, a lower reinforcing layer board and a lower surface layer board from top to bottom, the upper surface layer board and the upper reinforcing layer board are bonded through the adhesive, and the lower reinforcing layer board and the lower surface layer board are bonded through the adhesive. The composite core layer plate comprises the following raw materials in parts by weight: 30-40 parts of bamboo chips, 30-40 parts of wood chips, 20-30 parts of thermoplastic plastic and 5-10 parts of light calcium powder. The invention discloses a preparation process of the composite core layer plate. The invention relates to the technical field of bamboo-wood processing, and particularly provides a bamboo-wood composite board using a low amount of adhesive and a preparation process thereof. The bamboo-wood composite board uses less adhesive and has high connection stability among multiple layers of composite boards.

Description

technical field

[0001] The invention relates to the technical field of bamboo and wood processing, in particular to a bamboo and wood composite board using a low amount of adhesive and a preparation process thereof. Background technique

[0002] Bamboo grows fast and can effectively replace solid wood. It has a significant effect on reducing the price of consumer goods and protecting the environment. Bamboo-wood composite boards are widely used in daily life, such as chopping boards, furniture, floors, etc. Bamboo-wood composite boards are used in manufacturing The process requires a large amount of adhesive bonding, including the surface board and the wood core board. The surface board of the existing bamboo-wood composite board is generally made of bamboo strips glued and hot-pressed; the wood core board is generally made of a mixed blank mixed with wood chips and adhesives. Formation by hot pressing; both require the use of a large amount of adhesive, and the adhesive con...
