An opportunity of development of electrically conductive rubber based on industrially produced tire regenerate RShT-4 and Reg-1, obtained in laboratory conditions, with electrically conductive carbon fillers is shown. OMCARB CH85 carbon black (CB) produced by Omsktekhuglerod Ltd. and Tenax-e HTS-45 carbon fibers (CF) produced by Toho Tenax America were used as electrically conductive fillers. Curing and rheometric properties of regenerates with different content of Santogard PVI and electroconductive fillers were investigated. The study of the physical and mechanical properties of regenerates showed that introduction and increase of electroconductive CB and CF content in Reg-1 and RShT-4 leads to gradual reduction of elongation at break and increase in tensile strength and Shore A hardness, which is evidence of reinforcing effect of fillers. The effect of tensoresistance in the obtained regenerates depending on the content of electroconductive fillers is investigated. It is shown that addition of electroconductive CB to Reg-1 and RShT-4 imparts electroconductivity and tensoresistivity, that is, decrease in resistance in compression. Addition of CF leads to the opposite effect—increase in electrical resistance in compression. The possible mechanisms for the manifestation of tensoresistance at introduction of electroconductive CB and decrease in electroconductivity at introduction of CF are proposed.
