FIELD: chemistry.

SUBSTANCE: invention relates to a rubber mixture based on oil-filled butadiene-α-methylstyrene rubber and can be used to make industrial rubber articles for different industries - oil refining, pipeline transport, railway transport, as well as household articles. The rubber mixture is prepared by mixing the following components in pts.wt: oil-filled butadiene-α-methylstyrene rubber - 100, sulphur - 2, dibenzthiazole disulphide -1.5, diphenylguanidine - 0.3, zinc oxide - 5, stearic acid - 2, technical carbon - 50 and 0.05-0.5 sodium alginate. Sodium alginate is pre-mixed with powdered ingredients in a powder mixer.

EFFECT: invention increases fatigue endurance of rubber during multiple stretching and reduces heat build-up at constant strain amplitude.
