The improvement in performance properties of the tire is required to meet the ever-increasing demand from the automobile industries as well as to comply with the stringent environmental norms. At present, one of the most common methods adopted in the tire industries to balance the performance properties of rubber vulcanisates is either by using carbon black (CB), silica individually or their physical blends as reinforcing filler. However, the difference in surface energies between the two fillers prevents them from forming a collaborative filler network. To overcome this problem, use of advance materials like carbon–silica dual-phase filler (CSDPF) is need of the hour. The synthesis of this advanced CSDPF material involves the post process modification of CB using a surfactant followed by chemical precipitation of silica. In this study, the application of CSDPF series (3%, 5% and 7% silica impregnation on CB surface) is promulgated as an active reinforcing filler by replacing CB in PCR tire tread-based rubber compound. The improvement observed are for higher reinforcement index, improved abrasion resistance index and tear resistance compared to regular compound loaded with N330 CB and silica. The dynamic mechanical properties of rubber compounds indicate improved wet traction, dry handling, ride, and comfort properties while marginal increase in rolling resistance (RR). Among the tested variants of CSDPF material, the composite with 5% silica impregnation shows optimized performance properties. The study highlights the potential of using advanced hybrid CSDPF materials to enhance tire performance. |
