RUBBER MIXTURE FOR CURING Russian patent published in 2009 - IPC C08L7/00 C08L9/00 C08L9/06 C08K5/18 C08K13/02 

FIELD: chemistry.

SUBSTANCE: invention can be applied in tire production and rubber industries for obtainment of cured stock with long-term resistance to thermal oxidation and ozone ageing. Cured rubber mix includes natural or synthetic rubber, curing substances, curing boosters and activation agents, fillers and other additives, and composition age resistor in amount of 0.5-2.0 weight parts per 100 weight parts of rubber, including colloid silicic acid as powder carrier and liquid alloy of age resistors obtained at 70-90°C and containing N-isopropyl-N-phenyl-n-phenylenediamine - 21-22.5 and ε-caprolactam - 11-14. Additionally age resistor alloy includes 2,2,4-trimethyl-1,2-dihydroquinolin polymer - 10.0-11.5, stearic acid - 10.0-11.5, protection wax - 24.0-25.5.

EFFECT: enhanced resistance of cured stock to thermal oxidation and ozone.
