Abstract
The main objective of the current research work is to explore the effect of nanosilica particles on the compound EPDM/SBR-SiO2 (ethylene-propylene-diene monomer/styrene-butadiene rubber-nanosilica). The composite EPDM/SBR with and without silane coupling agent was processed using an open mill mixer. The nanosilica particles are prepared in the laboratory and were used as the reinforcing material in EPDM/SBR rubber composites. The cure characteristics, mechanical properties, hardness, rebound resilience, swelling resistance, abrasion resistance and compression set of the composites are completely analyzed and studied. Nanosilica particles are produced in the laboratory and used as reinforcement material in EPDM/SBR rubber compounds. Fully analyzed and examined are the cure characteristics, mechanical properties, hardness, rebound resilience, swelling resistance, abrasion resistance and compression collection of the composites. It was also evident from the result that with the inclusion of nanosilica particles in the EPDM/SBR rubber composites, the mechanical properties, swelling resistance, hardness, abrasion resistance and compression set properties improved.
Highlights
Rubber and its blends are commercially used in industries for engineering applications
The cure characteristics, such as minimum torque (Ml), maximum torque (Mh), delta torque (ΔM = MH - ML), scorch time, optimum cure time and cure rate index (CRI) for different compounds are clearly shown in Figure 2 (a-f)
The interactions at the nanosilica-Ethylene propylene diene monomer (EPDM)/styrene-butadiene rubber (SBR) interface are higher with the silane coupling agent
Summary
Rubber and its blends are commercially used in industries for engineering applications. The blended rubber compounds ensures higher mechanical properties and abrasion resistance, when it was mixed in the ratio 80 : 20 of EPDM/SBR [4]. These rubber blends are appropriately used as the matrix material for various industrial and engineering applications. The surface of nanosilica should be changed by silane coupling agent (SCA) which will in general improve the increases the rubber compatibility and interaction among filler and rubber compound which leads in the improvement of the mechanical properties of rubber composites [19]. It offered the unique significance for rubber reinforcement [20,21]
