Problems solved by technology

A kind of flame-retardant synthetic wood (CN200620057182.7), the board making process of this method is complicated, and industrial production is not used; the type of adhesive used is not specified, and the environmental protection of the board cannot be guaranteed; the pore diameter of the wood board layer is large (with a diameter of 3 to 20 mm Between) will affect the physical and mechanical properties of composite panels
[0003] There are also many reports on wood-plastic composite wood-based panels, but most of these wood-plastic composite panels are prepared by mixing and pressing plant fiber materials such as wood powder, sawdust, or crops and plastics. The board has high density, impact resistance, and nail-holding power. Poor, generally does not have flame retardant properties, not suitable for decoration and furniture materials, mainly because the materials are discarded after use and cannot be degraded, causing serious secondary environmental pollution

Abstract

The invention discloses environment-friendly flame-retardant degradable composite structure plywood and a manufacturing method thereof. The composite structure plywood is manufactured by taking fast-growing eucalyptus veneers as main raw materials and adopting nonwoven fabrics by prefabricated forming to replace adhesive. The nonwoven fabrics and the veneers can be manufactured into one piece, so that the environment-friendly flame-retardant degradable composite structure plywood is easy to realize industrial production, high in production efficiency, low in cost, capable of realizing true freeness of formaldehyde, good in flame-retardant performance, easy to degrade after being abandoned, and capable of realizing pollution freeness, low carbon and environment friendliness during plate pressing, processing, using and abandoning.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel production in wood science and engineering, and specifically relates to an environment-friendly flame-retardant degradable composite structure plywood and a preparation method thereof. Background technique [0002] At present, there are a large number of flame-retardant plywood made of adhesives at home and abroad. The products have different degrees of free formaldehyde. Although they have flame-retardant properties, they are not environmentally friendly. A kind of flame-retardant synthetic wood (CN200620057182.7), the board making process of this method is complicated, and industrial production is not used; the type of adhesive used is not specified, and the environmental protection of the board cannot be guaranteed; the pore diameter of the wood board layer is large (with a diameter of 3 to 20 mm Between) will affect the physical and mechanical properties of the composite plate.
