- Abstract
- Thermogravimetric tests were conducted under different heating rates and particle sizes in order to determine the kinetic parameters and the rubber tire composition. Three stages of degradation between 146-549 °C were found, in which components decompose in an independent and irreversible way. Synthetic rubber is the toughest component to be degraded, followed by natural rubber; plasticizer and additives were found as the most volatile components. The mentioned materials have the following activation energies: 135.4, 123.9 and 47.7kJmol-1 , respectively. The employed deconvolution model determined that tires are mainly composed of synthetic rubber in a greater proportion with 60.8%, followed by natural rubber with 32.8 % and finally plasticizers and additives with 6.1 %.
