High-density environment-friendly regenerated fibre board and production method thereof

Abstract

The invention discloses a high-density environment-friendly regenerated fiber board. The high-density environment-friendly regenerated fiber board is characterized by comprising an upper wood pulp layer, a lower wood pulp layer, an upper bonding layer, a lower bonding layer and a waste wood pulp main layer which are compounded together, wherein the waste wood pulp main layer is arranged between the upper bonding layer and the lower bonding layer; the upper wood pulp layer is compounded on the exterior of the upper bonding layer, and the lower wood pulp layer is compounded on the exterior of the lower bonding layer. The high-density environment-friendly regenerated fibre board is a substitute product for resources and is produced by the utilization of large amount of waste plant fiber such as waste paper or straw paper pulp; the price is low, and a large amount of forest resource can be saved; the upper and lower wood pulp layers are made of pure wood pulp; according to the fiber board, an efficient, energy-saving, environment-friendly and recyclable novel manufacturing process is adopted, so that the fiber board product has good waterproof property, is bent resistant, bright and clean in surface, bright in color, good in toughness and can be completely comparable with a pure wood pulp fiber board. The high-density environment-friendly regenerated fibre board can be widely applicable to industries of automotive interior, shoe making, artistic packaging, electrical appliance and furniture, can replace wood boards, wood pulp fiber boards and plastic boards, and has large market capacity and broad prospect.

Description

technical field [0001] The invention relates to a resource substitution product, in particular to a high-density environment-friendly regenerated fiberboard and a production method thereof. Background technique [0002] Fiberboard is also known as density board. The existing fiberboard is a wood-based panel made of wood fiber or other vegetable fiber and applied with urea-formaldehyde resin or other suitable adhesives. Fiberboard is an ideal raw material for high-end gift packaging, automotive interior lining, electrical circuit trays, shoemaking, furniture and other high-end products. It has high density, good water resistance, folding resistance, smooth surface, bright color and good toughness; but currently Some fiberboards are mainly made of raw wood, which are extremely expensive and have low utilization rates. It takes about 2.5-3 cubic meters of wood to manufacture 1 cubic meter of fiberboard, which seriously damages the ecological balance and has a great impact on t...
