Abstract

The invention discloses a process for preparing a sealing material with carbon fibers by Hatschek Process.The sealing material is composed of, by weight, 5-20% of the carbon fibers, 10%-25% of rubber latex and 55-75% of graphite powder.A preparation method of the sealing material includes steps: adding water into the carbon fibers to realize complete dispersion, and controlling the dispersion concentration of the carbon fibers within 5% to obtain a carbon fiber diluent; adding the graphite powder into the carbon fiber diluents, and well stirring to uniformly dispersing the graphite powder and the carbon fibers; slowly adding the rubber latex, stirring after addition of the rubber latex is finished, adding a compounding agent, and well stirring to obtain slurry, wherein the content of the compounding agent accounts for 5% of that of the rubber latex; adding a retention aid by a flow rate of 100-500ml / min into the slurry while adding water into the slurry until the concentration of the slurry is controlled within 1%, and then forming through a net to obtain the sealing material.

Description

technical field [0001] The invention relates to the field of sealing materials, in particular to a process for preparing sealing materials from carbon fibers by a scissoring method. Background technique [0002] As an internationally recognized high-performance material, carbon fiber has been widely used in various high-end fields. For now, the main reason why carbon fiber has not been widely used in the production of sealing materials by copying method is the bonding problem of carbon fiber. The scissoring method is a method of obtaining a sealing material by using water as the medium, bonding fibers and fillers through a binder, and then molding them on the Internet. Since carbon fiber does not have the ability to divide cellulose fibers into equal parts, its combination with fillers and other raw materials has limited its extensive application in the sealing material of the drawing method. Contents of the invention [0003] Aiming at the above-mentioned shortcomings i...
