Abstract

Clays belong to an economic class of fillers which are used extensively in rubber and plastics. Being non-reinforcing in nature there are limitations in their use. If the properties of filler are modified it may get higher value as a filler. To achieve this modification of surface properties is one of the avenues. In the present work the effect of treatment of coupling agent on clay has been studied with polybutadiene as a matrix. Composites were made with varying proportion of untreated and treated clay. A two-roll mill was used for dispersing the filler in the rubber and compression moulding technique was used to cure the compound in sheet forms. Tensile properties were measured on a computerised Universal Testing Machine according to ASTM procedure. Comparison of properties of composites filled with treated and untreated clay showed that treatment of clay imparted betterreinforcing properties. The properties under consideration were tensile strength modulus at100 and 400 Young s modulus hardness etc. Tensile strength improved by 54 whilst modulus at 400 was improved by 331. Similarly Young s modulus also improved by 297 at 90 p.h.r.
