Abstract
Proceso para la preparación de un caucho de estireno-butadieno que comprende polvo de caucho reciclado micronizado, el proceso que comprende los siguientes pasos: (a) preparar una suspensión que comprende polvo de caucho reciclado micronizado, agua y al menos un tensoactivo; (b) mezclar la suspensión obtenida en el paso (a) con al menos un látex de estireno-butadieno para obtener un látex de estireno-butadieno que comprende polvo de caucho reciclado micronizado; (c) someter el látex obtenido en el paso (b) a coagulación para obtener un caucho de estireno-butadieno coagulado que comprende polvo de caucho reciclado micronizado; en donde: en el paso (a) el tamaño de partícula del polvo de caucho reciclado micronizado varía de 0.05 mm a 0.8 mm, preferiblemente varía de 0.1 mm a 0.4 mm; en el paso (a) el por lo menos un tensoactivo está presente en una cantidad que varía de 0.5% en peso a 3% en peso, preferiblemente que varía de 1% en peso a 2.5% en peso, con respecto al peso total del polvo de caucho reciclado micronizado; en el paso (a) el polvo de caucho reciclado micronizado tiene una concentración en agua que varía de 1% en peso a 50% en peso, preferiblemente que varía de 5% en peso a 30% en peso, con respecto al peso total del agua. El caucho de estireno-butadieno que comprende polvo de caucho reciclado micronizado obtenido a partir del proceso mencionado anteriormente, tal cual, o en una mezcla con otros cauchos tal como, por ejemplo, caucho natural (NR), polibutadieno (BR), copolímeros de estireno-butadieno, o mezclas de los mismos, se puede usar ventajosamente en composiciones elastoméricas vulcanizables, que a su vez se pueden usar en diversos sectores tales como, por ejemplo, neumáticos, suelas de zapatos, frenos, correas transportadoras.
