Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania wiskoelastycznej biopianki poliuretanowej, w którym to sposobie komponent poliolowy zawierający mieszaninę polioli, substancję powierzchniowo-czynną, katalizator, przedłużacz łańcucha i wodę miesza się z komponentem izocyjanianowym, po czym wylewa do formy i sezonuje. Komponent poliolowy zawiera mieszaninę polioli, w skład której wchodzi 5% do 40% poliolu z tłuszczu zwierzęcego, od 0 do 37,5% mas. poliolu polieterowego na bazie sorbitolu, od 20% do 50% mas. reaktywnego wysokofunkcyjnego polioksyalikilenolu, 20% mas. poliolu polieterowego, kopolimeru blokowo-statystycznego tlenku etylenu i tlenku propylenu na bazie gliceryny. Wszystkie składniki komponentu poliolowego miesza się, po czym dodaje się do nich komponent izocyjanianowy z zachowaniem indeksu izocyjanianowego od 0,45 do 0,65, całość miesza się, wylewa do formy i sezonuje.
