Recycled rubber powder (PRR) is used as a filler and modifier for various elastomeric materials. Recycled rubbers include reclaimed rubber, ground rubber, or reprocessed synthetic rubber, by means any rubber waste that has been converted to an economically useful form. Composites based on elastomers and recycled rubber powder is a serious challenge for the environment. The main goal of this paper was to study the effect of rubber powder on the mechanical and thermal properties of elastomeric composites based on three precursors of the network. Triple blends were prepared using nonpolar natural rubber (NR), polyisoprene rubber (BR) and styrene butadiene rubber (SBR) (mass ratio 40/40/20). In all rubber compounds the CB/PRR ratio is constant (60). Samples were prepared using two roll mill. In the present work, the effect of the different ratio of powdered recycled rubber (PRR) on curing characteristics, mechanical properties before and after aging and thermal stability of NR/BR/SBR/CB/PRR rubber blends were investigated. Mechanical properties of elastomeric composites based on NR/BR/SBR/CB//PRR three network precursors after thermal aging at 100°C during 168h are significantly altered with an increase of the amount of powdered recycled rubber (PRR). The thermal degradation temperature shifts to a higher temperature up to 5 phr of PRR in NR/BR/SBR/CB rubber blend.
