Abstract RU 2548066 C1

FIELD: chemistry.

SUBSTANCE: rubber mixture contains the following, wt %: SKI-3 rubber 67.60-68.80, stearic acid 1.30-1.40, zinc oxide 3.30-3.50, sulphur gas 1.50-1.60, sulphenamide T 0.40-0.50, technical carbon N330 23.60-24.10, modifier - N-alkyl-4-nitroso-3-methyl-5-(2-naphthyl)-pyrazole 0.30-2.10. The alkyl is methyl or propyl or isopropyl. The modifier is obtained via catalytic step-by-step condensation of functionalised 1,3-diketone, amine and ketone.

EFFECT: invention improves the polymer-filler reaction and processing characteristics of vulcanised rubber.
