VULCANIZABLE RUBBER MIXTURE ON THE BASIS OF THE HYDROGENATED BUTADIENE-NITRILE CAOUTCHOUCK Russian patent published in 2007 - IPC C08L9/00 C08L33/00 C08L33/08 C08K13/02 

FIELD: rubber industry; production of the vulcanizable rubber mixture on the basis of the hydrogenated butadiene-nitrile caoutchouck.

SUBSTANCE: the invention is pertaining to production of the vulcanizable rubber mixture on the basis of the hydrogenated butadiene-nitrile caoutchouck used for manufacture of rubber-technical products efficient at the temperatures up to 150°С. The vulcanizable rubber mixture contains (in mass): the hydrogenated butadiene-nitrile caoutchouck - 70-95, the acrylate caoutchouck - 30-50, sulfur - 0.5-1.2, quaternary ammonium base - 2-6, sulfonamide Ц - 0.5-1.5, thiuram Д - 1-2, metallic stearate - 2-4, zinc oxide - 3-5, industrial carbon - 40-50, the stearic acid - 1-2, the antioxidant - 3.0-3.8. The technical result of the invention consists in reduction of the mixture viscosity, increase of the heat-resistance and the aggressive mediums-resistant properties with the simultaneous decrease of the residual compressive deformation.

EFFECT: the invention ensures the reduced mixture viscosity, the increased heat-resistant and the aggressive mediums-resistant properties at the simultaneously decreased of the residual compressive deformation.
