Abstract
The invention relates to the technical field of carbon fiber production, in particular to a surface treatment process for carbon fibers. The surface treatment process includes the steps that the carbon fibers are pretreated in the mode of being soaked in plasma water, the high hydrophobicity of the carbon fibers can be improved by the pretreatment, and the plasma oxidation effect in the later period is improved; the carbon fibers are bombarded with plasma so that the surfaces of the carbon fibers can be oxidized uniformly, oxidization is more uniform, and the surface activity is higher.
Description
Technical field
The present invention relates to carbon fiber production technical field, be specifically related to a kind of surface treatment of carbon fibers technique.
Background technology
Carbon fiber is by decomposition temperature lower than the fibre-forming polymer of melt temperature, by more than thousand degree solid phase pyrolysis.It not only has the intrinsic intrinsic property of material with carbon element, has again the soft machinability of textile fabric concurrently.It has, and specific strength is high, specific modulus is high, high temperature resistant, corrosion-resistant, a series of excellent properties such as endurance, creep resistant, in aviation, is widely used in the high-tech areas such as space flight.
But for the use of carbon fiber, undressed carbon fiber surface activity gene is few, surface inertness is large, poor with matrix compound tense cross section binding ability, there is more boundary defect, such as space, groove, impurity and crystallization etc.These problems limit the application to carbon fiber greatly.And solution to the problems described above mainly concentrates on carbon fiber surface treatment method, by processing its surface, making its surface have active group or improving its surface roughness, and then improving the adhesion strength between carbon fiber and matrix resin.
At present, general carbon fiber process is in acidic liquid, under the conditions such as certain temperature, electrolyte concentration, processing time, carry out surface oxidation treatment to carbon fiber.But electrochemical oxidation exists the uneven problem of oxidation processes, there is hidden danger in this safe handling for carbon fiber.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, provide a kind of and improve carbon fiber surface activity, oxidation evenly, can be enhanced productivity, and reduces the carbon fiber surface treatment method of production cost.
For achieving the above object, the technical solution used in the present invention is: its treatment step is:
1. will one end of surface-treated carbon fiber be needed to be fixed on guide pulley, due to the uppermost spray plasma water of guide pulley, rotate in the process of guide pulley, evenly soaked carbon fiber by plasma water and be progressively wrapped on guide pulley;
2. by carbon fiber, the one end be positioned at outside guide pulley is arranged on the side of ion conveyer belt, while rotating backward guide pulley, ion conveyer belt transmits from left to right, because the upper end of ion conveyer belt is provided with plasma emitter, be subject to the bombardment of beam-plasma in carbon fiber transport process, obtain the carbon fiber after surface treatment.
First carbon fiber is carried out the preliminary treatment that plasma water soaks by the present invention, and preliminary treatment can improve the strong hydrophobicity of carbon fiber, improves the effect of later stage plasma oxidation; By the method for carbon fiber being carried out to plasma bombardment, uniform alumina is carried out to carbon fiber surface, can oxidation be made evenly, surface-activity is stronger.
Beneficial effect of the present invention is: it can improve carbon fiber surface activity, and oxidation evenly, can be enhanced productivity, and reduces production cost.
Detailed description of the invention
The present invention is further illustrated below.
The technical scheme that this detailed description of the invention adopts is: its treatment step is:
1. will one end of surface-treated carbon fiber be needed to be fixed on guide pulley, due to the uppermost spray plasma water of guide pulley, rotate in the process of guide pulley, evenly soaked carbon fiber by plasma water and be progressively wrapped on guide pulley;
2. by carbon fiber, the one end be positioned at outside guide pulley is arranged on the side of ion conveyer belt, while rotating backward guide pulley, ion conveyer belt transmits from left to right, because the upper end of ion conveyer belt is provided with plasma emitter, be subject to the bombardment of beam-plasma in carbon fiber transport process, obtain the carbon fiber after surface treatment.
First carbon fiber is carried out the preliminary treatment that plasma water soaks by this detailed description of the invention, and preliminary treatment can improve the strong hydrophobicity of carbon fiber, improves the effect of later stage plasma oxidation; By the method for carbon fiber being carried out to plasma bombardment, uniform alumina is carried out to carbon fiber surface, can oxidation be made evenly, surface-activity is stronger.
The beneficial effect of this detailed description of the invention is: it can improve carbon fiber surface activity, and oxidation evenly, can be enhanced productivity, and reduces production cost.
The above, only unrestricted for illustration of technical scheme of the present invention, other amendment that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
