[Prior Art] Carbon fiber is a high-performance fiber that can be made into carbon fiber paper, carbon fiber felt, carbon fiber cloth, etc. It can also be used as a functional material such as shielding materials, heat-generating materials, conductive materials, chemical filter materials, etc. In the electronics industry, the battery industry, the chemical industry, as well as communications, defense and civil health. However, there is a problem in the processing of the above products, that is, how to make the carbon_beams in the base H or the dispersion of the solvent (10) finer carbon fiber bundles or single carbon fiber filaments, because each carbon fiber filament system will They are attracted to each other, so it is difficult for the carbon fiber system to fully exert its performance in the case of unprocessed separation, and the uniformity of dispersion will directly affect the performance in its work. The following are the methods used in the laboratory to separate carbon fiber bundles: (1) Dry dispersion method: mixing nanometer-sized powders (such as ultrafine Wei) with a diameter of about 0.01 to 〇1 μm with degummed carbon fiber microbeams. The nano-sized particles are dispersed on the surface of the carbon fiber monofilament to reduce the surface tension. The disadvantage of this method is that it is difficult to self-disperse the nano-sized powder material to the surface Φ of the miscellaneous filament, so that the effect is poor. (2) Wet Dispersion Method·· Disperse the dispersion into a general shape, add a carbon fiber bundle and continue to stir or ultrasonically vibrate and disperse to form a rhyme-shaped bundle to be dispersed into a carbon fiber bundle. Fine, the ship in the Qian Wei secret (4) placed in the (5) 3 201219621 solution in order to maintain the state of dispersion; the solution connection limits the available methods and scope 'so this method is not conducive to disperse into carbon fiber _ beam Use. Because of the disperse fresh addition, the wealth may have adverse effects on the strength of the composite material. At the same time, the age of the listening type cannot be prefabricated, stored and transported in large quantities, and it cannot be directly used in the process of many composite materials, which is not conducive to mass promotion. . (3) Surface treatment modification method: chemical and physical methods of carbon fiber surface oxidation (liquid phase, gas phase, electrochemical oxidation), plasma treatment, surface coating method, etc. The smooth carbon filament surface forms micropores and etched trenches, increasing the specific surface area, creating a surface morphology suitable for bonding, thereby reducing the surface tension of the carbon fibers and enhancing the physical interface bonding between the carbon fibers and other substrates. Introducing or grafting a functional group having a polar or reactive nature on the surface of the carbon fiber enhances the surface activity to increase the chemical bonding force of the carbon fiber and other substrates. Because the surface treatment modification method requires the use of high temperature heating, electropolymerization treatment, etc., or strong acid test, scaly (such as squaric acid, squaric acid, acid-filled diacid and hydrogen sulphate) Two money) and precious metal ion catalyst (silver platinum, ion) and other highly polluting or expensive chemical materials, not only cause environmental pollution, equipment cost and material cost are not conducive to mass production. SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a carbon fiber bundle dispersion method which can disperse carbon fiber bundles into carbon fiber bundles, which can be obtained by repeating the same carbon 201219621 fiber bundle by the present method.

The agent system forms a polymer film on each of the broken fiber bundles; the first drying step dries the carbon fiber bundles at a temperature higher than the curing temperature of the polymer film to polymerize the polymer The film hardening; the carbonization reaction step performs the gas phase oxidation reaction of the fine carbon fiber bundles to be dried at a temperature higher than the carbonization temperature of the polymer film, and the gas phase oxidation reaction of the polymer film is performed after the gas phase oxidation reaction Forming a plurality of carbon-based functional groups on the surface of the carbon fiber bundles; neutralizing the micro-acid step to immerse the fine-fiber bundles in a micro-invasive water-soluble 201219621 solution; washing away the alkali The material step immerses the fine fiber bundles in a neutral deionized water; the first drying step dries the fine fiber bundles at a temperature below 4 degrees Celsius and performs gas phase oxidation; The fine fiber bundles are dispersed. Through the above method steps, the originally aggregated carbon fiber bundle can be dispersed into a carbon fiber fine bundle 'and no other liquid is needed to assist the carbon fiber bundle to maintain the dispersed shape. Therefore, when blended into other substrates, the blending ratio is easier to control. And it is easier to evenly distribute the fine bundle of carbon fibers in the substrate. · Again, the same group of carbon fiber bundles are repeatedly subjected to the method of the gamma, which can be moved into a finer carbon fiber bundle until it is dispersed into carbon fiber. A variety of mixing 剌, 遂 is more convenient. In view of the above-mentioned advantages, in order to enable the reviewing committee to further understand the present invention, the present invention will be disclosed as follows. The embodiments of the present invention and the functions achieved by the present invention will be described in detail below with reference to the drawings and drawings.
