Synthesis & Utilization of Paddy Husk Carbon Black (PHCB) for Rubber Compounding

This study describes a procedure in which a compound has been formed by pyrolyzed rice husk at high temperature and subsequent grinding, which is intended to be used as a substitutional filler for carbon black in natural rubber compounds. This process has been investigated in order to develop a better value addition for rice husk which is a material source that is abundantly available in rice cultivating countries including Sri Lanka. The study has investigated effects on rheological and curing behavior, strength and elongation, hardness and resilience when using rice husk carbon black (RHCB) compared to regular N330 carbon black. The results indicated that non-modified RHCB does not contribute to strength improvement, but it is non-detrimental on elasticity and resilience of the compound.
