Evaluación de las propiedades mecánicas en mezclas de Poliestireno/Polietileno de baja densidad reciclado y tamizado

Abstract

En el presente trabajo se prepararon mezclas de poliestireno (PS) con residuo tamizado de Polietileno de baja densidad (LDPE) reciclado de cables eléctricos. Las mezclas se pr epararon utilizando una línea de extrusión mono-husillo a nivel planta piloto. Las mezclas, con concentraciones nominales de 5, 7.5, 15, 25 y 35 % en peso de residuo, fueron ensayadas bajo las configuraciones a tracción y a flexión. La evaluación mecánica se realizó en funció n del contenido de residuo y del número de pasos por extrusión mono-hus illo. En ambas configuracion es de ensayo se observó una disminución de la rigidez y la resistencia del PS al añadir el residuo de LDPE, aunque la ductilidad del PS se vio favorecida, lo cual se adjudicó a la naturaleza intrínseca de ambos materiales. Las obs ervaciones realizadas sobre la superficie de rotura de las mezclas permitieron apreciar la aglome ración del residuo dentro del PS, observ ándose dos fases distintas y muy bien definidas. Un segundo paso por extrusión mono-husillo perm itió mejorar la dispersión del residuo dentro del PS, aumentando la ductilidad de las mezclas reprocesad as sin afectar la rigidez y la resistencia.
