Abstract

Procedimiento para dispersar un antioxidante en pastillas en un polímero de aislamiento de cable eléctrico, caracterizado porque comprende mezclar un antioxidante con elevado punto de fusión con un vehículo que es un agente de curado para el polímero, teniendo el agente de curado una temperatura de fusión inferior que la del antioxidante y siendo capaz de formar una solución con el antioxidante, pero sin constituir disolvente del polímero, utilizando un agente de curado que compatible con el polímero y que es absorbido por las pastillas de polímero, llevando el antioxidante hasta las pastillas con una distribución uniforme en las mismas, y distribuyendo uniformemente la solución a través de un polímero compatible de aislamiento de cable eléctrico por migración y absorción en un mezclador de cinta.
