Chemical Degradation of Waste Tyre Rubber

Abstract

In this study, degradation studies of a small amount of waste tyre rubbers crumb were carried out using oxidative cleavage by inorganic and organic chemicals to decompose easily on account of cross linking and stabilizers. The experiments have been performed three reaction temperatures and time in the range of 130 ~ 150°C and 10 ~ 30 min. under atmospheric pressure. Experimental studies showed that the reaction lime, the reaction temperature, acidAvaste tyres rubber ratio, can be used to control the break down. The products selected for analysis in this study were obtained in the maximum yield conditions. Solid products were analyzed to determine their elemental composition and the chemical composition of liquid products were investigated spectroscopic techniques (GC/MS). Chemical reclaiming process is a possible method for devulcanizing the vulcanized network through the use of chemical agents that attack the C-S or S-S bonds, The new method seems to be applicable to the recycling of waste tyres.
