Abstract

The invention discloses an anti-radiation carbon fiber wooden composite fiber board. The anti-radiation carbon fiber wooden composite fiber board is manufactured by using the following raw materials in parts by weight: 100-110 parts of wood fibers, 10-11 parts of urea-formaldehyde resin adhesive, 10-11 parts of nanometer nickel, a right amount of absolute ethyl alcohol, 33-35 parts of 5-8mm short-chopped carbon fibers, 1.7-1.9 parts of acetone, 3.3-3.5 parts of isocyanic acid resin adhesive, 5.6-5.9 parts of ammonium chloride, 2.5-3 parts of nanometer titanium dioxide, 1.8-2.1 parts of Co3O4 nanowires, 2.2-2.5 parts of bentonite, 1.5-1.7 parts of polyethyleneimine and 8-10 parts of deionized water. The anti-radiation carbon fiber wooden composite fiber board has the beneficial effects that the Co3O4 nanowires are adsorbed in the bentonite by dispersing and mixing the Co3O4 nanowires and the bentonite, and then are coated with the polyethyleneimine, so that the affinity of the carbon fibers for the wood fibers is improved, and the Co3O4 nanowires can permeate the interiors of the wood fibers, thereby improving the toughness and compression resistance of the wood fibers.

Description

technical field [0001] The invention relates to the technical field of fiber boards, in particular to a radiation-proof carbon fiber wood composite fiber board and a preparation method thereof. Background technique [0002] With the rapid development of material science, functional composite materials have attracted more and more attention from scholars from all over the world. Among them, wood composite materials with high performance and high added value have gradually become a research hotspot in this field. In order to meet people's various performance requirements for wood materials, carbon fiber wood composites came into being. The most notable feature of composite materials is the designability of their microstructure, and the microstructure of materials will determine their macroscopic properties. However, due to the light weight and smooth surface of the carbon fiber during the processing of the board, it is difficult to mix evenly with the wood fiber and glue, an...
