Description

Method for preparing color carbon fiber material based on electropolymerization technology
Technical Field
The invention relates to the technical field of carbon fiber materials, in particular to a method for preparing a color carbon fiber material based on an electropolymerization technology.
Background
The carbon fiber is a high-strength and high-modulus fiber which is obtained by carbonizing and graphitizing organic fibers such as flake graphite microcrystals and has a carbon content of 95% or more. The fiber has many excellent properties, high axial strength and modulus, low density, high specific performance, no creep deformation, super high temperature resistance in non-oxidation environment, good fatigue resistance, specific heat and conductivity between nonmetal and metal, small thermal expansion coefficient, anisotropy, good corrosion resistance, good X-ray permeability, good electric and heat conductivity, good electromagnetic shielding property and the like, is a new generation of reinforced fiber, and is an important material in national defense, military industry and civil use.
The carbon fiber is graphitized fiber and has inherent characteristics of a carbon material, for example, the carbon fiber only presents single black color, if a carbon fiber product with other colors is obtained, only painting covering treatment can be carried out on the surface of the carbon fiber composite material, and the service performance of the carbon fiber composite material can be influenced by the paint film in color covering, the adhesion of the paint film to the surface of the composite material, the mechanical property of the paint film and the like, so that the carbon fiber material is limited in civil use.
Since carbon fibers are almost materials composed of carbon, the surface energy is low, the interfacial bonding property with other materials is poor, and the diameter of carbon fibers is small, there are many problems in changing the color thereof by the surface coating method: the colored paint is difficult to fix on the surface, and the binding force is poor; the traditional coating method has thick paint film, changes the size of the carbon fiber and the performance of the fiber; uniform coating is difficult and the operation process is complicated … …. therefore, the carbon fiber surface modification technology is always in a blank state and the preparation of colored carbon fibers is also always in a blank state for various reasons.

(4) fiber electropolymerization post-treatment: and washing and drying the electropolymerized fiber.

Preferably, the vinyl ether monomer is one or more of propylene oxide benzyl ether, propylene oxide phenyl ether, propenyl glycidyl ether, ethylene glycol diglycidyl ether, 1, 4-butanediol diglycidyl ether and ethylene glycol divinyl ether.
Preferably, the epoxy resin is one or more of glycidyl ether epoxy resin, glycidyl ester epoxy resin, glycidyl amine epoxy resin, alicyclic epoxy resin, bisphenol a epoxy resin, hydrogenated bisphenol a epoxy resin, brominated epoxy resin, silicone-modified epoxy resin, organic phosphorus epoxy resin, polyurethane epoxy resin, bisphenol F epoxy resin, bisphenol S epoxy resin, and novolac epoxy resin.
Preferably, the toner is one or a mixture of organic dye, inorganic dye, organic pigment or inorganic pigment.
Preferably, the mass fraction of the toner is 1-20% of the whole.
Preferably, the cationic photoinitiator is: diphenyliodohexafluorophosphate, 4' -diphenyliodohexafluorophosphate, sulfonium triarylhexafluorophosphate, sulfonium triarylhexafluoroantimonate, potassium hexafluoroantimonate, sodium hexafluorophosphate, silver hexafluoroantimonate, 1-butyl-3-methylimidazolium tetrafluoroborate, 1-butyl-3-methylimidazolium hexafluorophosphate, tetraphenylphosphonium hexafluoroantimonate, 1-butyl-3-methylimidazolium hexafluoroantimonate, tris [4- (dibutylamino) phenyl ] ammonium hexafluoroantimonate, 4-octyloxybis (diphenyliodonium hexafluoroantimonate), bis (4-dodecylbenzene) iodonium hexafluoroantimonate, N-ethylpyridinium hexafluorophosphate, 1-butylpyridinium hexafluorophosphate, 1-ethylpyridinium hexafluorophosphate, 1-hexyl-3-methylpyridinium hexafluorophosphate, 1-ethyl-3-methylimidazoline trifluoro (trifluoromethyl) borate, 1-butyl-3-methylimidazoline dibutyl phosphate, 1-butylpyridinium tetrafluoroborate, 1-butyl-4-methylpyridinium hexafluorophosphate, 1-octyl-3-methylimidazolium hexafluorophosphate, 1-butylpyridinium hexafluorophosphate, trimethyloxonium hexachloroantimonate triphenyl carbon pentachloronitine stannic acid.
Preferably, the mass of the initiator added in the step (2) is 0.05-5% of the mass of the monomer.
Preferably, in the step (4), the electropolymerized product is washed with deionized water and ethanol and then dried.
The invention has the beneficial effects that:
(1) because the conductive base material is immersed in an electropolymerization system, after electrification, the initiator is initiated on the surface of the base material and decomposed into cations, so that the monomer or resin is initiated to polymerize, and the polymerization extends outwards from the surface of the base material, and the adhesion between the polymer and the base material is very good due to the growth mode. The reason is that the carbon fiber is not only a coated object, but also a conductor for providing electric conduction, electrons are conducted from the surface of the carbon fiber to an initiator which is in contact with the carbon fiber, namely the initiator on the surface of the carbon fiber, the initiator is decomposed on the surface of the carbon fiber to generate anions and cations, the cations can initiate the functional groups such as epoxy and the like adjacent to the carbon fiber on the surface of the carbon fiber to be polymerized and grown, the initiated cations and the epoxy polymerization growth process of the cations are always in a cationic state, and the cations in the initiation and growth processes are always adsorbed on the surface of the carbon fiber due to the principle that a large amount of electrons pass through the surface of the carbon fiber and the cations are attracted by positive and negative electricity.
In addition, the polymerization of monomers into macromolecules has a volume contraction due to the conversion of the van der waals radii between the molecules into chemical bonds, which if not supplemented in time by more monomers, would remain in the coating resulting in very large internal stresses and thus poor adhesion. For example, in photopolymerization, due to the directionality of illumination, polymerization starts from the upper layer solution, the bottom layer, i.e., the surface of the base material, is finally illuminated, and polymerization finally occurs, so that no external monomer is supplemented in the polymerization of the bottom layer, the volume shrinkage is obvious, the internal stress is large, and the adhesive force of the polymer coating film is greatly reduced. In the electropolymerization process of the carbon fiber surface, polymerization starts from the bottom layer, and the upper layer solution can be timely supplemented to the lower layer, so that volume shrinkage is timely supplemented by the solution, the solution is greatly reduced or eliminated, and finally generated polymers have good adhesive force with the carbon fiber surface. When the polymer film grows to a certain thickness (only a few microns), the polymer film becomes an insulating layer, so that the surface of the carbon fiber is not conductive any more, the polymerization is automatically terminated, the thickness of the polymer film layer is not increased any more, the thickness of the film layer can be automatically controlled, and the increase of the fiber size is limited.
(2) Under the action of current, the initiator ionizes anions and cations, and the cations can initiate polymerization of epoxy and vinyl ether monomers. Because electropolymerization starts to initiate the outward growth from the surface of the conductive base material, and in addition, oxygen atoms, hydroxyl groups and the like on the epoxy polymer have better binding force with the surface of the base material, the binding force between the coating and the base material is good.
(3) The carbon fiber has good conductivity, and can be used as a good base material for electropolymerization, so that the electropolymerization can be realized on the surface of the carbon fiber, and the performance of the surface of the carbon fiber is improved.
(4) If the toner is added into the polymerization system, the toner is solidified in the polymer film layer when the monomer is solidified, so that the surface of the carbon fiber is uniformly coated with a layer of color ink, and the surface of the carbon fiber can be changed into different colors by different color inks, thereby enabling the carbon fiber to have various colors.
The method utilizes an electric polymerization technology to carry out electric polymerization on the surface of the carbon fiber material, modify the surface performance of the carbon fiber, prepare the colored carbon fiber, improve the interface bonding force between the carbon fiber and a composite material matrix and widen the application field of the carbon fiber; the method has simple process flow and operation and remarkable effect.
