Abstract

This study focuses on physical and mechanical properties of natural rubber reinforced carbon black for effect of tapioca starch loading. Tapioca Starch (TS) is used as organic based filler for Natural Rubber (NR) as a primary matrix material by using literature based formulation in search of improvement on their physical and mechanical properties. The main objective of this research is to study the effect of physically modified tapioca starch on the properties of the Natural Rubber compound. Physical modification of the tapioca starch is through thermal treatment by heating the tapioca below its pasting temperature of about 50°C ± 0.1°C to improve compatibility with the natural rubber compound. The compound will undergo a few testing to determine both physical and mechanical testing. Tensile testing will be performed to determine various mechanical properties. Tensile test and Shore hardness test will determine physical properties of the compound. Morphology of the compound will be observed under optical microscopy. The optimum compounding formulation of the fabricated compound wasobserved at the combination of natural rubber compound and tapioca starchbased on 100 phr of the natural rubber (NR) SMR-20 and different proportions tapioca starch (TS) at 5, 10, 20, 40 and 60 phr. Curing additives for all those formulations based rubber were 2.5 phr of Sulphur (s), 5 phr of Zinc oxide (Zn0), 2 phr of stearic acid, 1 phr of Tetraethyl ThiuramDisulphate (TMTD) and 1 phr of 6PPD.
