Abstract

Procedimiento y formulaciones para la obtención de materiales compuestos termoplástico/lignina en un mezclador termocinético en condiciones de degradación térmica que garantizan una adecuada dispersión de la lignina en la matriz termoplástica y dan lugar a materiales cuyas propiedades físicas, mecánicas y térmicas les confieren diversas aplicaciones. El proceso de amasado-plastificación correspondiente, se realiza en dos etapas: primera, calentamiento y fusión del termoplástico; segunda, mezclado del polímero con la lignina. De este modo se logra reducir al mínimo el tiempo que la lignina está sometida a temperatura elevada y se minimiza a su degradación térmica.
