Wood-plastic composite board and preparation technology and equipment thereof

Abstract

The invention discloses a wood-plastic composite board and a preparation technology and equipment thereof. The wood-plastic composite board is made of core layer materials and surface protective film materials, wherein the core layer materials comprise wood meal, thermoplastic materials and auxiliaries; the surface protective film materials comprise a protective film resin and modifying agents. According to the wood-plastic composite board, a conventional wood-plastic secondary laminating is not carried out to the wood-plastic board, a multi-layer co-extrusion method is adopted to form the wood-plastic board in one step, the production efficiency is high, the combination of the surface layer and the core layer is firmer, and the performance of the composite board is more excellent.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a coated wood-plastic composite board with good environmental protection and high strength, a preparation process and equipment thereof. Background technique [0002] Wood-plastic composite panel is a kind of high-tech green environmental protection material, which is mainly made of fiber materials such as wood as basic materials, thermoplastic polymer materials and processing aids, etc., and then is heated and extruded by mold equipment. With the properties and characteristics of wood and plastic, it is a new type of composite material that can replace wood and plastic. With the gradual development of wood-plastic technology, the application of wood-plastic panels has become increasingly widespread, such as the furniture industry, interior decoration industry, packaging industry, vehicle and ship interior industry, and the future wooden housing construction industry, the f...

AI Technical Summary

Problems solved by technology

The board has high strength and wear resistance, but has the following disadvantages: 1) When processing, it is necessary to brush the glue first, and then paste the panel, which is complicated and inefficient; 2) The use of adhesive reduces the environmental protection of this composite board.

This technical solution provides a wood-plastic composite board that is mixed with various wood materials and has a small amount of additives, so that wood materials account for half of the total. However, due to the reduced amount of wood materials used in this wood-plastic board, only Made using lamination process
