Abstract

The results of an experimental study of the effect of small (0,2–1,5 phr) concentration C of additions of graphene on the rheological and mechanical properties of tread rubber and rubber compounds are presented. Two tread compounds based on blend of BR and two SBR, filled with carbon black (CB) of different activity N220 (AT) and П803 (MT) were studied. Viscosity η at 100 and 160 °С as well as scorching at 131°С were measured by viscometer Muney MV 2000, rheological properties – by MDR2000. Mechanical properties were tested by Tensometer Т-10 abrasion µ – by MIR-1 device. A slight increase in η and an increase in the temperature upon mixing by 5–7 °C were shown. The effect of C on the strength properties is insignificant: the change in tensile strength within 0,7 MPa cannot be considered as significant. An increase in µ with C was shown for tread rubber of MT as CB, but for rubber of AT as CB µ practically doesn’t change. So µ increases for rubber of inactive CB and doesn’t change for rubber of active one. The general conclusion: in contrast to the model rubbers, the properties of tread rubbers cannot be significantly improved by graphene addition.
