Problems solved by technology

[0003] Ordinary wood fiberboard is easy to absorb moisture in the environment, causing defects such as deformation of the board and decline in mechanical properties, which affects the service life
In addition, because ordinary fiberboard is prone to mildew, it cannot be used in a warm and humid environment, which greatly limits the application field of fiberboard.

Abstract

The invention provides a production technology of a graphene fiber board. The production technology comprises the steps: peeling and slicing raw wood; cleaning the wood chips; performing cooking; performing hot grinding to obtain wood chip fibers; putting the dried wood chip fibers into a glue applying device, and applying glue, wherein the glue comprises a graphene-based additive; drying the glued wood chip fibers; pre-pressing to obtain a formed fiber board blank; feeding the formed fiber board blank into a hot press for hot press molding; coating the upper surface and the lower surface of the fiber board blank with graphene anti-corrosion layers; enabling a flame-retardant fiber layer to be attached to the graphene anti-corrosion layer and located on the upper surface of the fiber board blank, and forming the flame-retardant fiber layer by compounding wood fibers, a flame retardant and an adhesive; attaching a nano graphene layer to the flame-retardant fiber layer, wherein the nano graphene layer is a single-layer nano graphene layer; performing cutting; and stacking and curing. The fiber board is simple in production process and high in efficiency, and has anti-corrosion and waterproof functions.

Description

technical field [0001] The invention relates to the technical field of production of fiberboards, in particular to a production process of graphene fiberboards. Background technique [0002] As an emerging nanomaterial, graphene has good barrier and shielding properties, as well as high conductivity and high strength. Combining graphene materials with traditional anti-corrosion coatings, graphene-modified anti-corrosion coatings have good anti-corrosion effects , low coating thickness, high adhesion, light paint film, excellent salt spray resistance and other advantages, it is a good upgrade alternative to traditional anti-corrosion coatings; graphene has a good physical barrier to small molecules; Diffusion path: The diffusion path of the corrosive medium is extended, and the service life of the substrate is increased; at the same time, the cost increase after adding graphene is far lower than the anti-corrosion benefit brought by it, so graphene is expected to become a goo...
