Abstract

The present invention discloses a kind of flame-retarding wave-absorbing type carbon fiber composite wood board, for the layer structure body of Split type structure, by by common plank I, hardwood plate and common plank II submerge pretreatment using alkali lye, fire retardant is handled and dried, the common plank I is connected by the first wood glue layer with polyimide layer pressing in order, the polyimide layer is connected by the gluing oxidant layer of the first flame-retarding wave-absorbing with carbon fiber layer pressing, the carbon fiber layer is formed by connecting by the gluing oxidant layer of the second flame-retarding wave-absorbing with hardwood plate pressing, the hardwood plate is connected by the second wood glue layer with the common pressing of plank II.The composite wood board flame-retarding wave-absorbing of the present invention, oxygen index (OI) reaches 42~48, parallel-to-grain compressive strength>100MPa, bending strength>200MPa, compares lead equivalent>0.012Pb/mm, can effectively absorb the electromagnetic waves such as infrared, X, α, β ray, and shielding property is high.The invention also discloses a kind of manufacture method of flame-retarding wave-absorbing type carbon fiber composite wood board.

Description

A kind of flame-retarding wave-absorbing type carbon fiber composite wood board and its manufacture method
Technical field
The present invention relates to a kind of composite wood board, a kind of flame-retarding wave-absorbing type carbon fiber composite wood board and its manufacture are specifically related to Method.
Background technology
Timber is graded by 90% cellulose, hemicellulose, lignin, water and 10% extract and ash to be constituted, main Want molecular structure, property and the mutual relation of chemical composition to be not only the material base of the various properties of timber, be also timber Basis that is modified and fire-retardant, inhaling ripple processing.
With the development of science and technology, absorbing material has special purposes, especially in military field, play the role of it is important, Secondly, people are needed to touch increasing electrical equipment in work and daily life, and these electrical equipment can all be produced more or less Electromagnetic radiation, so as to produce harm to health, absorbing material can effectively absorb various harmful rays. As the timber of one of four big main materials, had a wide range of applications in paint industry, convert it to inhale ripple material with reference to some techniques Material (increase polyimides, carbon fiber and suction ripple adhesive, three is absorbing material), while changing the inflammable and mechanics of timber The shortcoming of poor performance, therefore, the strong high resistant of research mechanical property burn and suck wave mode timber and had great significance.
A kind of intelligent absorbing materials of patent CN201610730593.6 and preparation method thereof, describe a kind of intelligent suction Wave material and preparation method thereof, the intelligent absorbing material inhales ripple layer, low frequency comprising high frequency successively from top to bottom and inhales ripple layer and base Bottom.High frequency inhales ripple layer to absorb the absorbing material of 2GHz-18GHz frequency ranges, comprising top layer high frequency absorbing material and being embedded at table Intermediate layer high frequency absorbing material in floor height frequency absorbing material, the additive that the high frequency inhales ripple layer uses carbonyl iron particles.Low frequency Ripple layer is inhaled to absorb the absorbing material of 1GHz-2GHz frequency ranges, and the absorbing material additive uses FeSi particles.Basalis includes gold Category substrate and the DM being embedded in metal substrate.Patent CN201010148080.7 membrane structure Ku band radars are inhaled Wave material, describes a kind of waves-absorbing material for Ku waveband radar with film structure, main to include six layers of absorbing material layer and five plastics Film, every two layers of absorbing material interlayer of six layers of absorbing material layer is equipped with plastic sheeting, and the first layer absorbing material layer is 1.50 parts of coupling agent, 50 parts of diluent, 150 parts of ferrite, the mixture of 53.67 parts of 60% epoxy resin；The second layer is inhaled Wave material layer is 1.50 parts of coupling agent, 50 parts of diluent, 150 parts of carbonyl iron absorbent, 39.83 parts of 60% epoxy resin, solidification The mixture that 12.93 parts of agent；The third layer absorbing material layer is 1.50 parts of coupling agent, 50 parts of diluent, carbonyl iron absorbent 150 parts, 109.02 parts of 60% epoxy resin, the mixture of 33.10 parts of curing agent；Described fourth, fifth, six layers of absorbing material layer are 1.50 parts of coupling agent, 50 parts of diluent, 150 parts of carbonyl iron absorbent, 39.83 parts of 60% epoxy resin, 12.93 parts of curing agent Mixture.A kind of heat-conducting type absorbing materials of patent CN201610471044.1 and preparation method thereof describe a kind of heat-conducting type and inhale ripple Material and preparation method thereof.Heat-conducting type absorbing material, including following components：Absorbing material binding agent, absorbing material and auxiliary agent；Press Mass percent meter, absorbing material binding agent is 99.2%-99.7%, and absorbing material is 0.2%-0.5%, and auxiliary agent is 0.1%- 0.3%；The absorbing material is graphite alkenes material.Above patent is all directly to prepare absorbing material, is Fe basis suction wave material, Inhale intensity of wave poor, complex manufacturing technology, cost is high, it is impossible to combined with timber.
The content of the invention
The invention aims to overcome that above-mentioned timber is inflammable and poor mechanical property and the shortcoming and defect of ripple can not be inhaled, A kind of flame-retarding wave-absorbing type carbon fiber composite wood board and its manufacture method are provided.
Patent of the present invention is by the way that absorbing material addition on wood glue, to be formed to the suction new wood glue of ripple, then glued polyamides Asia Amine and absorbing carbon fiber wave material, material mechanical performance and fire resistance (polyimides and carbon fiber can also be improved while inhaling ripple Material, which has, preferably inhales ripple and fire resistance, expansible to apply in wide range of areas such as textile, plastics and metal composites).
