Novel process flow for carrying out surface treatment on carbon fiber

Abstract

The invention relates to a novel process flow for carrying out surface treatment on carbon fiber, aiming at realizing the purposes that burrs on the surface of produced carbon fiber are remarkably reduced, the mechanical property of the carbon fiber is enhanced and the energy source consumption is reduced. The technical scheme for realizing the purposes is as follows: the novel process flow for carrying out surface treatment on the carbon fiber comprises the following steps: surface electrolysis treatment; water washing; extrusion with a rubber roller; starching; drying; and rolling. The surface of the carbon fiber is treated by adopting a surface electrolysis treatment method; the treated carbon fiber is subjected to starching treatment to form a carbon fiber bundle; the starched carbon fiber bundle is subjected to drying treatment so as to size the carbon fiber bundle; and the dried carbon fiber is wounded into a bobbin shape by a fiber rolling machine and is then packaged for marketing and sales after rolling treatment. Compared with the carbon fiber produced by adopting the traditional surface treatment process, the carbon fiber produced by using the novel process flow disclosed by the invention has the advantages of short process flow, high production efficiency, remarkably-reduced burrs on the appearance, slightly-increased mechanical property index and reduced energy source consumption, and thereby the novel process flow for carrying out surface treatment on the carbon fiber is worthy of application and popularization.

Description

technical field [0001] The present invention relates to the field of organic chemistry, and belongs to polymer material manufacturing technology, specifically a novel carbon fiber surface treatment process flow. Background technique [0002] Carbon fiber is a fibrous carbon material with a lower density than metal aluminum, but higher strength than steel, and has the characteristics of corrosion resistance and moldability. It has both the "hard" inherent nature of carbon materials and the "soft" processability of textile fibers. It is a new generation of military and civilian dual-use new materials, widely used in aviation, aviation, transportation, sports and leisure products, medical treatment, machinery, textiles and other fields. The carbon fiber industry plays an important role in the upgrading of pillar industries in developed countries and the improvement of the overall quality of the national economy. It is also of great significance to the adjustment of my country'...

Problems solved by technology

The drying process is completed in a drying furnace. With this surface treatment method, the carbon fibers produced are prone to fuzz, have unsatisfactory mechanical properties, and consume more energy during the production process.
