RUBBER MIXTURE Russian patent published in 2017 - IPC C08L9/02 C08K3/00 C08K5/00 

FIELD: chemistry.

SUBSTANCE: rubber mixture contains hydrogenated butadiene-nitrile rubber, butadiene-nitrile rubber, vulcanizing agent - novoperox "БП-40", vulcanization activators - zinc stearate and magnesia burnt, antioxidant - agidol-2, fillers - carbon black "Н" 220 and carbon black "П" 514, plasticiser - dibutyl phthalate, rubber lubricant - polymethylsiloxane liquid-200, modifier - thiokol "НВБ-2" and co-agent of peroxide cure. The mixture additionally contains an antioxidant - diaphene "ФП", retarder scorch - captax, technological additive lubstab-01 or oxanol "ЦС-100", and as co-agent of peroxide cure contains deltagran 50DL.

EFFECT: improvement of the conditional tensile strength, tear strength by improving the dispersion of the components of the mixture in the matrix of rubbers and the high resistance of the rubber to aging in aggressive hydrocarbon media at elevated temperatures.
