Abstract

The aim of this research is to investigate the effect of phosphate type accelerator (ZBPD) and silane (TESPT) on the physical and mechanical properties of cure rubber compound. Currently in the development for rubber product of DECATHLON group, thiazole accelerator is restricted in all component for skin contact sportwares due to thiazole accelerator comes with the side-effect of high human health hazard risk. Hence, ZBPD and TESPT is used to replace thiazole accelerator due to the functionality of the new formulation is close to the function of thiazole accelerator which is to accelerate the rubber curing process. About three physical and mechanical testings (cure characterisation, tensile and hardness, swelling properties) and three characterisation methods (FTIR, SEM, OM) have been used in this study. In this research, rubber formulation with the present of MBTS primary accelerator and DPG secondary accelerator is being compared with the rubber formulation with the present of ZBPD, ZDBC and TESPT silane coupling agent. After testing and analysis, result shows that the rubber formulation with ZBPD shows better mechanical properties when compared with the conventional rubber formulation with MBTS accelerator. On the other hand, the rubber formulation with the present of TESPT does not improve the mechanical properties of the cure rubber compound due to insufficient processing temperature in the first stage mixing process causing the rubber compound to be have a scorch and pre-mature behaviour. Hence, ZBPD accelerator is recommended to replace MBTS accelerator in the rubber formulation.
