FROST RESISTANT RUBBER MIXTURE WITH THERMAL EXPANDED GRAPHITE Russian patent published in 2009 - IPC C08L9/02 C08K3/04 C08K3/06 C08K3/22 C08K5/09 C08K5/47

Abstract RU 2356918 C2

FIELD: chemistry, engineering process.

SUBSTANCE: present invention pertains to rubber industry, to production of elastic and wear resistant rubber based on butadiene-nitrile rubber. The rubber mixture contains the following, in wt.pts: butadiene-nitrile rubber - 18 with content of acrylonitrile - 17-23 wt % - 100, sulphur - 2.45-2.65, captax - 1.45-1.55, zinc oxide - 2.4-2.6, technical carbon "П803" - 1.4-1.6, thermal expanded graphite - 8-12.

EFFECT: improved elasticity and reduced bulk wear during abrasion, with significant reduction of content of technical carbon, which increases sealing ability and operational life of sealing devices, used in mobile friction assemblies.
