RUBBER MIXTURE Russian patent published in 2007 - IPC C08L21/00 C08K3/04 C08K13/02 

FIELD: rubber industry; chemical industry; building material industry; production of the industrial rubber goods and building materials.

SUBSTANCE: the invention is pertaining to the rubber mixture and may be used at production of the industrial rubber goods and the building materials, for example, as the elastic additive in the various coatings. The rubber mixture contains (in mass shares) the caoutchouc CKC-30 ARKM-15-100, brimstone - 2.0-4.5, altaks (vulcanization accelerator) - 2-4, zinc oxide- 5-7, stearin -1.5-5.0, the carbon-containing filler -50-100. As the carbon-containing filler use the spent activated charcoal with the ash content of less than 3.1 mass % and with the specific surface area exceeding 150 m²/g. The technical result of the invention is the utilization of the carbon-containing wastes of the water and the gas purification, expansion of the range of the rubber mixtures fillers, improvement of the physical-mechanical indexes of the produced highly filled rubber mixtures and reduction of the produced rubber mixtures prime cost.

EFFECT: the invention ensures the utilization of the carbon-containing wastes of the water and the gas purification, expansion of the range of the rubber mixtures fillers, improvement of the physical-mechanical indexes of the produced highly filled rubber mixtures and reduction of the produced rubber mixtures prime cost.
