Rubbers Based on Butadiene Containing Elastomers Filled Plasma-treated Polyacrylonitrile And Carbon Fibers Waste

Abstract

The study examines elastomeric composite materials based on combinations of nitrile butadiene rubbers, as well as blends of general-purpose rubbers, filled with polyacrylonitrile and carbon fiber waste treated with low-pressure high-frequency capacitive discharge plasma.

It has been shown that the introduction of fiber waste leads to a significant change in the properties of vulcanizates obtained from special-purpose rubbers (BNKS-18AN and BNKS-28AN) and general-purpose (IR + BR + SBR).

Waste polyacrylonitrile (PAN) fiber and carbon fiber (CF) waste were plasma-treated incorporated into rubber compounds for molded rubber goods based on standard formulations: PAN fiber at a dosage of 10 phr (parts per hundred rubber), or a combination of PAN fiber and CF at dosages of 5 and 5 phr, respectively.

Mooney viscosity, vulcanization characteristics of rubber compounds, and physical-mechanical properties of vulcanizates were determined before and after aging. It was shown that the overall performance of rubber compounds containing plasma-treated PAN fiber and carbon fiber (CF) waste is comparable to that of compounds containing untreated PAN fiber and CF waste in both formulations.
