Title:Graphene/rubber composite and its application in the tire industry
SymposiumB19 Rubber Composites

Abstract

Currently, environments and energy problems are most concerned. In the rubber field, two effective ways including decreasing the use of oil-dependent fillers and increasing rubber properties are adopted to save energy and protect environments. Therefore, it is better to choose oil-independent fillers and use green preparation process. Graphene has attracted more and more attentions due to its ultrathin sheet structure, high modulus, electrical and thermal conductivities. Also, graphene has shown some advantages in increasing strength, air impermeability and other properties of rubber composites. In this research, a green preparation process for graphene/rubber was used. The relationship between microstructure and properties of composites was investigated. Furthermore, the graphene/rubber composites were applied in the passenger car tire (PCR), off-the-road tire (OTR) and truck tire. The results showed that there was an obvious increase in modulus at 100%, cut resistance, abrasion resistance, air impermeability and fatigue properties of rubber composites after adding graphene.
