Intensification of rubber chemical cross-link and reinforcement by the modified pyrolytic carbon black from scrap tires
Pyrolysis has the potential of transforming waste into recyclable products. Pyrolytic carbon black (PCB) is one of the most important products from the pyrolysis of used tires. Techniques for surface modifications of PCB have been developed. One of the most significant applications for modified PCB is to reinforce the rubber matrix to obtain high added values. Techniques for surface modifications of PCB have been developed. The rubber vulcanization and reinforcement properties of pyrolytic and modified carbon black were investigated and compared with those of commercial carbon black. The cross-link structure, relaxation and self-diffusion properties were investigated by solid-state high resolution nuclear magnetic resonance respectively. Demineralization and modification with NDZ-105 titanate coupling agent not only intensify the interactions between carbon black and the neighboring polyisoprene chains, but also increase the chemical cross-link density of the vulcanized rubber with TWPC. TWPC could be used to replace the commercial semi-reinforcing carbon black.
