Preparación y caracterización de compuestos de Capirona-Polipropileno y Capirona-Polietileno de alta densidad

Abstract

Se presentan los resultados de la caracterización de compuestos madera-polímero, obtenidos a partir de residuos particulados de Capirona de 710 µm con polipropileno y polietileno de alta densidad. Estos han sido mezclados con anhídrido maléico y extruidos a una temperatura entre 150 y 180 ºC, obteniéndose pellets pequeños de forma cilíndrica. Posteriormente, los pelletes han sido prensados en forma de probetas y tratados térmicamente a 170 ºC. Algunas probetas han sido gamma-irradiadas con fuente de cobalto-60. Las muestras fueron sometidas a pruebas de ensayos mecánicos y de biodegradación con el hongo Polyporus sanguineus y Schizophyllum commune. Se han observado cambios en las propiedades mecánicas, especialmente cuando se tiene como insumo el polipropileno, mejorando la flexión del compuesto, con el polietileno también se ha notado una mejora en la resistencia a la degradación y disminución de la absorción de agua.

In this work we show the characterization results of the wood-polymer composite, obtained by Capirona particulate at 710 microns with high density polyethylene and polypropylene. These have been mixed with maleic anhydride and extruded at a temperature between 150 and 180 °C, yielding small cylindrical pellets. Subsequently, the pellets were pressed into test pieces and heat treated at 170 °C. Some of those pieces have been gamma-irradiated with a cobalt-60 source. The samples were subjected to mechanical tests and biodegradation tests with the Polyporus sanguineus and Schizophyllum commune fungus, changes were observed in mechanical properties, especially when it has as input polypropylene, improving bending the compound, also polyethylene have noticed an improvement in resistance to degradation and reduced water absorption.
