FIELD: production of rubber; production of rubber mixture for manufacturing of vulcanization diaphragms. SUBSTANCE: proposed rubber mixture comprises, mas. %: butyl rubber, 100; resin, 6-8; zinc oxide, 3-5; stearic acid, 2-4; modifying agent, 0.3-0.9; solid unoxidized oil bitumen having softening point not lower 130 C 3-10; technical carbon, 40-60. Relative stress of thus prepared articles at 300 % elongation is 61-63 kgs/cm2, its relative strength at tension is 142-146 kgs/cm2, fatigue resistance and multiple bending is 458000-480000 cycles. EFFECT: improved quality of desired product. 1 tbl
