Abstract
Kaolin is a mining material widely used as a filler in the manufacture of various types of finished goods made from natural rubber. Kaolin in this study was used as a special filler for solid tires for two-wheeled electric scooters commonly used by children. The purpose of this study was to determine the effect of the kaolin loading on the curing properties of the rubber compound, the mechanical properties of the vulcanizate, and the thermal properties of the rubber vulcanizate. Kaolin loading was varied from 22 to 42 per hundred rubber. The compounds were mixed on a two-roll mill. The vulcanization process took place at 140 °C for 17 minutes. The test results showed that kaolin loading had a strong effect on the maximum torque, scorch time, optimum vulcanization time, and mechanical properties of the vulcanizate. Thermo gravimetric analysis showed that the thermal stability of the vulcanizate was influenced by kaolin loading.
