Resumen
Este estudio evalúa la influencia de caucho reciclado (RR) con un tamaño de partícula específico en las propiedades de mezclas, mezclas de polipropileno reciclado/polietileno (RPP) y RR (RPP/RR). Las proporciones de RPP/RR para obtener los compósitos fueron como sigue: 90/10 (PP90), 75/25 (PP75), 60/40 (PP60) and 45/55 (PP45). El tamaño de partícula empleado del RR fue 850 µm. Las propiedades de las mezclas, fueron evaluadas por análisis reométrico, termogravimétrico (TGA), calorimetría diferencial de barrido (DSC), microscopia de barrido electrónica (SEM), densidad, índice de fluidez y ténsil. El torque máximo incrementó con el contenido de RPP. Por análisis DSC se observó que el RPP exhibió dos temperaturas de fusión, la primera correspondió al polietileno de baja densidad (LDPE) y la segunda al polipropileno (PP). Además, el RR afectó la cristalinidad del RPP. Por análisis de SEM y TGA, se determinó que el RR y el RPP contenían rellenos. Las densidades de las mezclas fueron más altas que la del RPP. El índice de fluidez exhibió una tendencia con la cantidad de RR.
