摘要
Physical properties of composites from mica and styrene-butadiene rubber (SBR) have been studied with special reference to the effect of silane coupling agent (A-174) in the compound. Tensile and tear properties increase with the addition of mica. The increase of tensile properties is more pronounced in the case of silane-treated mica. Silane treatment also raises the volume fraction of rubber in solvent-swollen rubber vulcanizate. Attempts have been made to correlate the changes in properties with the network structure of rubber. In order to understand the mechanism of failure, tensile fracture surfaces have been examined by scanning electron microscopy (SEM). The fractographs have been correlated with the strength and type of failure of these composites. The observed values of viscosity (rheometric) corresponds to the calculated values from existing theory based on the hydrodynamic model of dispersed particles in a fluid medium.
