Abstract

The invention discloses a carbon fiber wooden composite fiberboard modified by zinc borate. The carbon fiber wooden composite fiberboard is prepared from, by weight, 100-110 parts of wood fiber, 10-11 parts of urea-formaldehyde resin adhesive, 10-11 parts of nano nickel, an appropriate amount of absolute ethyl alcohol, 33-35 parts of 5-8 mm chopped carbon fiber, 1.7-1.9 parts of acetone, 3.3-3.5 parts of isocyanate resin adhesive, 5.6-5.9 parts of ammonium chloride, 2.5-3 parts of nanometer titania, 2.5-3 parts of mesoporous cobalt aluminate, 2.2-2.5 parts of mesoporous molecular sieves and 2-2.3 parts of zinc borate. Mesoporous cobalt aluminate, mesoporous molecular sieves and zinc borate are used and permeate into wooden fiber, so that the strength of wooden fiber is improved, bending strength, bending modulus and impacting strength of a plate are improved, harmful substances can be adsorbed, and the flame retardation can be improved.

Description

technical field [0001] The invention relates to the technical field of fiberboards, in particular to a zinc borate modified carbon fiber wood composite fiberboard 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,...
