Problems solved by technology

[0007] There are also some other patents on nanomaterial preparation methods, such as application numbers 01124193.4 and 01120284.X, which are consistent with the patents applied by Qi Zongneng on this point. They do not involve the content of natural plant fibers, and the existing technologies must be first Through the organic intercalation treatment of layered silicate in liquid solvent, after that, it can be melted with polymer to prepare nanocomposite after filtering, drying, grinding and sieving

Abstract

A nano-class composite wooden material for plate, tube, or section is proportionally prepared from laminar silicate, high-molecular resin, natural plant fibers, inorganic filler, and chemical assistant through proportional mixing, and extruding out or injection moudling. It is possible to granulate before it is shaped.

Description

technical field [0001] The nanocomposite wood material and preparation method of the present invention relate to the technical field of building materials; in particular to the technical field of building material materials and methods; in particular to the technical field of nanocomposite wood building materials and methods; in particular to the technical field of nanocomposite wood materials and preparation methods. Background technique [0002] At present, wood generally has the defect of swelling when wet and shrinking when dry, and its size and shape are greatly affected by environmental changes. Taking the existing wood-based panels on the market as an example, the density of general particleboard, fiberboard, OSB, MDF and other products is less than 1.0g / cm 3 , It contains many adhesives such as phenolic formaldehyde and urea formaldehyde, and the residual formaldehyde is slowly released, which stimulates the respiratory tract, and stimulates the eyes to cause tears, ...
