Abstract

Procedimiento para la preparación de una masa de caucho de silicona que se endurece totalmente a temperatura ambiente bajo la acción de la humedad, con un contenido de poli(cloruro de vinilo) o de copolímeros de éste junto con aditivos usuales, tales como reticuladores, aceleradores, materiales de carga, caracterizado porque: a) se distribuye un plastisol del poli (cloruro de vinilo) o de copolimeros de éste en un siloxano, teniendo el siloxano grupos reactivos, especialmente grupos hidroxilo, y siendo la proporción cuantitativa de plastisol a siloxano de 30 a 70% en peso; b) se calienta la mezcla a temperaturas de 100 a 220, hasta que el plastisol del poli(cloruro de vinilo) o de copolimeros, de éste, dispersado en el polisiloxano reactivo, esté gelificado totalmente, se enfría a temperatura la masa obtenida, luego c) se añade un silano, que tiene por lo menos tres grupos capaces de reaccionar con los grupos reactivos de siloxano, y d) en este preparado se distribuye un catalizador dereticulación, especialmente un compuesto orgánico de estaño, y eventualmente un acelerador, trabajándose, al menos en las etapas c) y d) del procedimiento con exclusión de la humedad del aire y pudiéndose agregar materiales de carga en momentos cualesquiera del procedimiento.
