ELASTOMERIC MATERIAL Russian patent published in 2011 - IPC C08L9/06 C08L21/00 C08K3/04 C08K3/36 

FIELD: chemistry.

SUBSTANCE: invention relates to rubber industry, particularly to an elastomeric composite material for making different industrial rubber articles. The elastomeric material is made of a composition containing the following in pts.wt: general purpose carbon-chain rubber 100, main filler - ground schungite mineral particle size of 6-60 nm 10-150, sulphur vulcanisation accelerating system 1.5-8.0, activator - zinc oxide 1-4, stearic acid 0.5-4.0, optional additional filler selected from technical carbon, colloidal silica, chalk, kaolin 0-80, special additives 0-25, and oil 0-30. The sulphur vulcanisation accelerating system is a combination of sulphenamide C and altax in ratio of 3:1-2:1 or sulphenamide C and diphenyl guanidine in ratio of 2:1-4:1.

EFFECT: elastomeric material has high rate of vulcanisation, low viscosity and good elastic and strength properties.
