Pembuatan karet riklim dari ban bekas dengan microwave ditinjau dari karakteristik vulkanisasi kompon

The research is aimed to study the effect of heat of microwave in the preparation of reclaimed rubber from used tire and the application of rubber compound observed from the characteristics of its vulcanization. Reclaimed rubber is found from used tire treads that ground and shifted using 10 mesh of shifter. Devulcanization was carried out in microwave with power output from 0, 100 ? 200 watt. The reclaimed rubber was used as the natural rubber substitute, with proportion of 20, 40, and 60 parts per hundred of rubber. The cracteristic of the compound was tested by using Rheometer whereas the reactivity of the rubber against the Vulcanizing agents was observed by using Fourier Transform Infrared Spectrophotometer. The results showed that reclaimed rubber prepared by heating in microwave with power output of 100 and 200 watt as well as without heating treatment showed significant effect to characteristic of vulcanization. Proportion of utilization of reclemed rubber as much as 20,40 and 60 parts showed significant effect to characteristic of vulcanization. Proportion of 40 part reclaimed rubber prepared by microwave heating with power output 100 watt showed the best characteristic of vulcanization.
