Abstract

The invention provides a wood-plastic wall panel and a production method thereof. By adding bamboo fiber or bamboo powder and oxidized starch, a network structure is formed under the curing and crosslinking action of sodium hydroxycellulose. On the one hand, the network structure can be Effectively buffer the external impact and reduce the brittleness of the board; secondly, the bamboo fiber or bamboo powder particles can be filled in the gaps of the PCV resin particles, so that the strength of the board is greatly improved, and as time goes by, the strength of the board will become stronger. Higher, acid and alkali, light and rain corrosion, not easy to age, prevent mold or insects; third, can greatly reduce the amount of calcium carbonate and wood powder, reduce the water absorption of the board.

Description

technical field [0001] The invention relates to the technical field of building panels, in particular to a wood-plastic wall panel and a production method thereof. Background technique [0002] Wood-plastic wall panel, wood-plastic, that is, wood-plastic composite material, is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, with more than 35% -More than 70% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce plates or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. [0003] The ...
