Abstract

1334718 Recovering rubber UNION CAR BIDE CORP 13 Sept 1971 [14 Sept 1970] 42518/71 Heading C3E Rubber is recovered from fabric or fibrereinforced rubber articles by cooling the articles, or subdivided pieces thereof, with a cryogenic material to a temperature sufficiently below - 40‹ C. to embrittle the rubber component, disuniting the rubber component from the fibrous component by flexing, crushing or comminution and removing at least part of the fibrous component by mechanical or cyclonic separation. The separation step may involve screening of the disunited material and, when metal is to be removed, passage through a magnetic separator. The rubber chunks obtained may be further comminuted in, e.g., a ball or hammer mill or a fluid energy device, cooled by coolant recovered from the embrittlement stage, to yield particles which are then screened and classified, using a dispersant such as carbon black or silica, if desired. The entire process may be carried out under cryogenic conditions. The particles produced may be devulcanized.
