Abstract
A method of bonding natural or synthetic rubber to polyethylene comprises inserting either at least three bonding layers each composed of a mixture of natural or synthetic rubber and polyethylene of graded composition such that each successive bonding layer proceeding from the polythene to the rubber contains a greater proportion of rubber, or a layer comprising one such layer which also contains an acid carbon black, and then heating to vulcanize and autogenously heat bond the layers to each other. In Examples applied to the manufacture of electric cables (see Group XXXVI) the rubber layer consists of crude natural rubber, sulphur, zinc oxide, stearic acid, mercaptobenzthiazole, petrolatum and aldol a naphthylamine, and the four intermediate layers made from 60, 50, 40, and 30 per cent. respectively of natural rubber, the remainder being polyethylene. Alternatively the rubber layer consists of neoprene, magnesium oxide. Dixie clay, zinc oxide, dibutyl ammonium oleate, furnace carbon black, cottonseed oil, vulcanised vegetable oil and phenyl b -naphthylamine, and the intermediate layer consists of 60 parts of polyethylene, 40 parts of neoprene and 10 parts of acid carbon black preferably with an average particle size of 5 millimicrons.
