Effect of mixture of Reclaimed tire and Carbon Black Percent on the Mechanical properties of SBR/NR blends

This article explores the possibility of using mix of reclaim powder and carbon black as reinforcement in natural rubber/styrene–butadiene rubber (NR/SBR). Mix of reclaim and Carbon Black materials used in this research to enhancement some of the mechanical properties of SBR/NR blends as additives or fillers. 16 different compound was prepared from SBR(100,80,60.50)pphr ,NR (0,20,40,50) and 4 loading level from C.B (10,20,30,40) pphr ,Reclaim (10,20,30,40)pphr in series while the hardness ,tensile strength, tear résistance, elongation, elastic modulus, fatigue ,and specific gravity have been studied in this research. We found that some of these properties are increasing with the increment of mix of C.B, reclaim loading , such as hardness ,specific gravity ,tensile strength ,tear resistance ,elastic modulus from other hand fatigue, elongation , were decreased with increment C.B, reclaim loading %.
