Abstract
La invención se refiere a un procedimiento simplificado para fabricar productos de material sintético termoplástico que contiene un plastificante, en particular PVC flexible, por medio de una máquina de extrusión. Para ello, el material sintético termoplástico se alimenta en forma de polvo, gránulos finos, mezcla seca o similar directamente a la extrusora, en la que se calienta en una primera sección hasta una temperatura de 50-140ºC. En la extrusora, el plastificante se inyecta en el material sintético termoplástico a una temperatura de 50 a 140ºC. El material sintético termoplástico se mezcla entonces homogéneamente con el plastificante en la extrusora. La mezcla se calienta mediante fricción, y se mezcla de forma que el tiempo de retención medio del material desde la inyección del plastificante hasta el momento en que el material alcanza la temperatura media de 145ºC, está entre 10 y 120 s. El material sintético termoplástico absorbe completamente al plastificante. La mezcla homogénea dematerial sintético termoplástico y de plastificante se calienta después en la extrusora hasta una temperatura superior a 145ºC y se funde el plastificante completamente. En una versión ventajosa del procedimiento, 2-30% de plastificante es pre-mezclado mediante un procedimiento conocido con el polvo de PVC para formar una mezcla seca, y el resto del plastificante se introduce en la extrusora.
