METHOD OF OBTAINING RUBBER MIXTURE ON BASIS OF DIENE RUBBER Russian patent published in 2017 - IPC C08J3/20 C08L21/00 B29B13/08 

FIELD: technological processes.

SUBSTANCE: method for producing rubber mixture based on diene rubber consists in pretreating for one or two minutes one or more rubber compound components selected from rubber, a sulfur crosslinking agent, a vulcanization accelerator, a vulcanization activator, and a silicic acid filler in an electromagnetic apparatus under the influence of variable electromagnetic field. The electromagnetic field is created by moving magnetic elements from magnetically hard material. Then rubber mixture is made on the traditional mixing equipment.

EFFECT: increasing the cohesive strength of rubber compound, increasing the vulcanization rate, the degree of crosslinking, slowing the reversion, reducing the dosage of vulcanizing group ingredients, which reduces the cost of the rubber mixture and its vulcanizates.
