Abstract
Procedeul pentru obtinerea unui compound pe baza de poliuretan prin taierea la dimensiuni de 15-20 cm a poliuretanului elastomer microcelular recuperabil, rezultat din procesul de turnare directa sau din procesul de injectie, macinarea de 10-25 mm, preîncalzirea acestuia la 60...120 degree C, urmata de degazare prin trecere prin valturi încalzite la aceeasi temperatura si macinare la dimensiuni de 2...6 mm, conform inventiei, consta în aceea ca, poliuretanul astfel pregatit se amesteca în proportie de 5...50% în greutate cu granule de copolimer butadiena-stiren într-un malaxor de tip Bambury sau într-un extruder, la temperatura de 110...140 degree C, în final compoundul granulîndu-se prin metode mecanice sau termomecanice.
