Study on Mechanical Properties of Natural Rubber by Carbon Black/Graphene/White Carbon Black

Abstract

Abstract Graphene (GE) and white carbon black (SiO2) were added to natural rubber (NR) to partially replace carbon black (CB). The effects of different filling ratios of CB/GE/SiO2 on the mechanical properties of NR were investigated. The data were processed by orthogonal experiment. The results showed that when the mass fraction of CB was 41g, the mass fraction of GE was 4g, and the mass fraction of SiO2 was 1g, the maximum true strain in the mechanical properties of NR was 139.8%. The maximum true stress is 85.695 MPa, and it is indicated that41g CB, 4 g GE, and 1 g SiO2 are added to the NR as the optimum filling ratio.
