Description
Technical field
The present invention relates to a kind of means of defences of continuous carbon fibre oxygen chemoprevention water suction.
Background technique
Carbon fiber is a kind of fibrous carbon material, its intensity is bigger than steel, density ratio aluminium is small, under vacuum conditions than heat-resisting
Steel also high temperature resistant, with the fiber with electric conductivity similar in copper, be all unique in terms of electricity, calorifics and mechanical property
The new material of energy.
Due to the good mechanical, electricity of carbon fiber itself and chemical property, carbon fiber all has in many fields is potentially answered
Use prospect.Single Zhi Zucheng of carbon fiber includes two kinds of diameters: 7 microns and 9 microns.Usually used carbon fiber is usually multiple lists
The aggregate of branch carbon fiber is combined with each other by multiple carbon fibers.Carbon fiber is substantially a kind of high performance carbon-based material,
Substantially still with carbon characteristic, such as be easy in air at high temperature aoxidize, burning, be easy to absorb water, and once water suction or
Person's oxidation, mechanical performance and electric property all can degradations.So in practical applications carbon fiber be usually with resin or
Person's metal is made into polymer matrix composites or metal-base composites, after structure optimization, meets mechanical or electric power and answers
Needs.Master's thesis " the preparation and its property of phenol-formaldehyde resin modified carbon fibre composite of Changchun Polytechnic Univ. Li Honglong
Can research " preparation and performance that just report modified phenolic carbon fibre composite, 2~3% are added in phenolic resin
Carbon fiber can both improve the electric conductivity (in June, 2017, Changchun Polytechnic Univ.'s Master's thesis) of phenolic resin.
Although carbon fiber has certain electric conductivity, its electric conductivity still will be weaker than the metal materials such as copper in practical application
Material, in order to improve the electric conductivity of carbon fiber, China Civil Aviation flight engineering college has studied improvement of the Copper Plating of Carbon Fiber to its performance,
The result shows that electric conductivity greatly improves after carbon fiber shows copper facing, can be used for aircraft it is anti-lightning strike (Liang Ke, Zhang Huadong,
The preparation of Qin Wenfeng carbon fibre composite metal copper coating and its electric conductivity research [J] glass reinforced plastic/composite material, 2016
(05):61-64).Yang Zhong etc. has studied the electric conductivity of different carbon-fibre reinforced epoxy resin composite materials, it was demonstrated that works as fiber cloth
Its electric conductivity also gradually increases that (Yang Zhong, Xue Haopeng difference carbon-fibre reinforced epoxy resin composite material are led when overlapping area increases
Electrical property studies the Tianjin [J] science and technology, 2017,44 (07): 63-64+67).University Of Tianjin Wang Rui has studied carbon fiber surface progress
Metallization is applied to the technology of battery shielding, the results showed that after carbon fiber surface serialization nickel plating, which meets
Needs (Wang Rui surface Metalliztion of Continuous Carbon Fiber and its composite material electromagnetic shielding performance research [D] days of electromagnetic shielding
Saliva university, 2012.)
Carbon fiber has preferable electric conductivity, therefore hot property and electrical property are always the emphasis that everybody pays close attention to, Tang Mingjing
Etc. the hot property and electrical property of polyether-ether-ketone/carbon fiber (PEEK/CF) composite material for having studied melt-blending process preparation, as a result
Show to increase to 10% with carbon fiber mass fraction, conductivity of composite material, which can show, exceedes infiltration effect, but excess effusion value compared with
Height, after Overheating Treatment, ascendant trend is presented in the higher composite material resistance rate of carbon fiber content, and (Tang Mingjing, Deng Jianguo are congratulated
Research [J] plastics industry of Jiang Ping, Luo Shikai polyether-ether-ketone/carbon fibre composite hot property and electrical property, 2009,37
(04):53-56.).National University of Defense technology's fourth beach has studied carbon fiber electric heating composite material in wind power generation blade anti-ice and height
Cold area weaponry deicing keeps the temperature demand, it was demonstrated that carbon fiber has preferable performance (Ding Haibin carbon fiber in the composite
Composite electrothermal material preparation and performance study [D] the National University of Defense Technology, 2014.).Beijing University of Chemical Technology Chen Tong has studied
The processing technology of thermoplastic conductive composite material, it is indicated that the technological parameters pair such as screw in injection molding machine revolving speed, injection pressure, dwell pressure
The composite material volume resistivity all have an impact (research [D] the Beijing University of Chemical Technology of Chen Tong conductive thermoplastic composite material,
2015.)。
Existing result of study shows that carbon fiber can prepare thermoplasticity and same with thermosetting compound material is used for heating device,
In these materials carbon fiber as filler perhaps reinforcing material typically using chopped strand or fibrofelt carry out using.
If carbon fiber as continuity fiber is changed to chopped strand or fibrofelt is carried out using carrying out the processing that is chopped, which increase
Difficulty of processing and process complexity, if it is possible to which process complexity will be substantially reduced by directly carrying out heating using continuous fiber, be subtracted
Low difficulty of processing, while the continuity of carbon fiber is also maintained, be conducive to the intensity and toughness that improve device.But continuous carbon fiber
Dimension is in use if in use, being susceptible to aoxidize or adsorb air under the conditions of air or other oxidizing atmospheres
In moisture, substantially reduced so as to cause the performance of carbon fiber, while also reducing the service life of carbon fiber.How carbon fiber is prevented
By the corrosion of other pollutants such as oxidizing atmosphere and water, guarantee good mechanically and electrically performance and chemical stabilization
Property, just become a great problem for needing to overcome in carbon fiber application.
This patent using middle this faced technical problem, develops a kind of continuous carbon fibre for continuous carbon fibre
Anti-oxidant, waterproof protective technology, by coating one layer or several layers of flexible thermoplastic resins on continuous carbon fibre surface, in the company of holding
While continuous carbon fiber flexible, the suction that avoids the corrosion by oxygen and other oxidizing atmospheres in air and prevent moisture etc.
It is attached.
