Abstract

Przedmiotem zgłoszenia jest sposób sieciowania i modyfikacji mieszanin kauczuku chloroprenowego z kauczukiem butadienowym, na drodze ogrzewania tych mieszanin z tlenkiem metalu oraz ze zmiękczaczem, który polega na tym, że stosuje się mieszaninę zawierającą 80 - 20 części wagowych kauczuku chloroprenowego i 20 - 80 części wagowych kauczuku butadienowego, a jako tlenek metalu stosuje się tlenek miedzi(II) w ilości 1 - 5 części wagowych na 100 części wagowych mieszaniny kauczuków oraz jako zmiękczacz kwas stearynowy w ilości od 0,5 do 2,5 części wagowych na 100 części wagowych mieszaniny kauczuków, przy czym sieciowanie i modyfikację prowadzi się w temperaturze co najmniej 423 K w czasie wynikającym z oznaczeń wulkametrycznych.The subject of the application is a method of cross-linking and modifying mixtures of chloroprene rubber with butadiene rubber by heating these mixtures with a metal oxide and a plasticizer, which consists in using a mixture containing 80 - 20 parts by weight of chloroprene rubber and 20 - 80 parts by weight of rubber butadiene, and as the metal oxide copper(II) oxide is used in the amount of 1 - 5 parts by weight per 100 parts by weight of the rubber mixture, and as a plasticizer stearic acid in the amount of 0.5 to 2.5 parts by weight per 100 parts by weight of the rubber mixture, where cross-linking and modification are carried out at a temperature of at least 423 K for the time resulting from the vulcametric determinations.
