METHOD OF PRODUCING RUBBER FROM ELASTOMER COMPOSITION BASED ON SYNTHETIC RUBBER Russian patent published in 2016 - IPC B29C35/00 B29C35/02 B29C70/64 B29C70/66 C08L23/16 

FIELD: rubber industry.

SUBSTANCE: invention relates to a rubber industry, in particular to technology of manufacturing a sheet of elastomeric material for formation of composite materials based on rubber mixtures and solid ash microspheres, and may be used at factories producing rubber products. Method of producing rubber from elastomer composition based on synthetic rubber includes introduction of filler into sheet workpiece of elastomeric material based on ethylene-propylene rubber with help of rolling. Filler used is solid ash microspheres with dispersion of 60-200 mcm, which can withstand a load of 20-40 MPa. After rolling vulcanisation is carried out at temperature 150 °C-160 °C and pressure of 1.0-1.5 MPa.

EFFECT: disclosed method enables to obtain material with following characteristics: tensile strength - 5,26 -6,06 MPa; relative elongation at break - 304-381 %; density of composite material - 0,92-0,95 g/cm³.
