The preparation method of the carbon fluoride fiber comprises the steps of treating the carbon fiber in a mixed solution of lithium fluoride and hydrochloric acid, and then adjusting the pH value of the carbon fluoride fiber. And the diameter of the carbon fluoride fibers is greater than 10 microns.
The invention uses the function of the carbon fluoride fiber to improve the connection strength with other main matrixes of the antistatic rubber sleeve elastomer sheath material.

The invention mainly uses the synergistic effect of strontium sulfate and carbon fluoride fiber, because the strontium sulfate has lower dielectric constant, the strontium sulfate and the carbon fluoride fiber can form an interactive antistatic network channel when being mutually stacked, and the surface resistance of the strontium sulfate and the carbon fluoride fiber is reduced. Because the diameter of the carbon fluoride fiber is larger, and the strontium sulfate has better lubricating effect on the carbon fluoride fiber, the carbon fluoride fiber is promoted to be uniformly mixed in the antistatic rubber sleeve elastomer sheath material.

While polyethylene wax can act as a lubricant to increase compatibility with polyvinyl chloride. The nano calcium carbonate acts with the epoxidized soybean oil to increase the stability of the invention.
