METHOD OF PRODUCTION OF THE RUBBER COMPOUND ON THE BASIS OF THE CHLOROPRENE RUBBER Russian patent published in 2007 - IPC C08J11/00 C08J3/28 C08K13/02 C08K3/04 C08K3/22 C08K5/09 C08K5/18 

FIELD: petrochemical industry; rubber industry; other industries; methods of production of the rubber compound on the basis of the chloroprene rubber.

SUBSTANCE: the invention is pertaining to the field of rubber industry, in particular, to the method of production of the rubber compound on the basis of the chloroprene rubber, which is characterized by the heightened adhesiveness metrics. Production of the rubber compound on the basis of the chloroprene rubber includes mixing of magnesium oxide, zinc oxide, the stearic acid and carbon. At that during the mixing process additionally introduce the modifying agent, which has been preliminary produced as a result of interaction of the epoxy dianresin -ED-20 with the vat wastes of the residue of phenylamine production in the mass ratio of 2:1 at 150°С within 5 hours. At that the vat waste contain 15-18 mass share of phenylamine. The vulcanizates of the rubber compound based on the chloroprene rubber are characterized by the improved physical-mechanical metrics and the heightened adhesion to the metal. The method allows to salvage of the phenylamine (other name aniline) - the waste of the petrochemical industry.

EFFECT: the invention ensures production of the rubber compound based on the chloroprene rubber characterized by the improved physical-mechanical metrics and the heightened adhesion to the metal.
