Title A name given to the resource Modelo de Deconvolución para la Cuantificación de los Componentes del Caucho Vulcanizado Presente en los Neumáticos Fuera de Uso Creator An entity primarily responsible for making the resource Isaac Meza Trujillo, Ernesto Hale de la Torre Chauvin Description An account of the resource Resumen: Se efectuaron ensayos termogravimétricos a distintas velocidades de calentamiento y con diferentes tamaños de partícula con el objeto determinar los parámetros cinéticos y la composición del caucho de llantas. Se determinó que existen tres zonas de degradación entre 146-549 °C en las cuales se descomponen los distintos componentes de forma independiente e irreversible. Se encontró que el componente más resistente a la degradación fue el caucho sintético, seguido del caucho natural y como componente más volátil los plastificantes y aditivos, manifestando energías de activación de 135.4, 123.9 y 47.7 KJ mol-1 respectivamente. El modelo de deconvolución empleado, determinó que el caucho sintético se encuentra en mayor proporción con un 60.8 %, seguido por el caucho natural con un 32.8 % y por último los plastificantes y aditivos comprenden un 6.1 %. 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 independently 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 %.
