METHOD OF PROCESSING ELASTOMERIC WASTES Russian patent published in 2011 - IPC C08J11/04 C08L21/00 C08K13/06

Abstract RU 2408616 C2

FIELD: chemistry.

SUBSTANCE: method of processing elastomeric wastes from production of high-moisture carbon-chain synthetic rubber involves dehydration in a closed rubber mixer, extrusion machine or an assembly with additional hot air blowing, unloading and processing on rollers. Spent bentonite and diatomite from production of plant oil are then added, cooled and an elastomeric composition having moisture content of not more than 2.0%, Mooney viscosity of 40-70 arbitrary units is obtained. The obtained product is further used in preparing rubber mixtures.

EFFECT: improved environmental friendliness, low cost of rubber mixtures.
