Abstract
325,207. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 3, 1928. Divided' on 324,959. Plastic compositions containing natural and synthetic rubber and carbon black.-Carbon black, suitable for use in the rubber industry, is produced by treating in the gaseous phase unsaturated hydrocarbons or gases containing the same. if desired with the addition of other gases and vapours, at low or moderately elevated temperatures with a dehydrogenating catalyst comprising a metal from the iron group, or a compound, such as an oxide, of the metal, and an addition giving increased activity, in order to decompose the hydrocarbons giving carbon black In a vulcanization process, 60 parts of the carbon black obtained by the process are mixed between friction rollers with 100 parts of a plastic polymerization product obtained from butadiene by means of sodium, 15 parts of magnesium carbonate., 2 parts of sulphur, 6 parts of stearic acid, 3 parts of a resin and 1 part of a mercaptobenzothiazole, and the mixture is vulcanized for 40 minutes at about 140‹ C. In another vu]- canization process, 40 parts of carbon black derived from ethylene are mixed with 100 parts of a plastic polymerization product of butadiene, 25 parts of magnesium oxide, 2.5 parts of sulphur, and 0.5 parts of vulcanization accelerator, the sheet produced being vulcanized for 15 minutes at about 140‹ C. Specification 321,402, [Class 90, Non-metallic elements], is referred to.
