RUBBER MIX BASED ON FLUORINE-CONTAINING ELASTOMER Russian patent published in 2001 - IPC

FIELD: antifriction metal and rubber coatings. SUBSTANCE: rubber mix comprises, wt parts: fluorine-containing elastomer, 100; resorcinol, 6; triethylbenzyl ammonium chloride, 3; magnesium oxide, 15; barium sulfate, 10-20; calcium fluoride, 15; impact detonation diamond graphite, 5-15. Mixing is carried out on rolls with friction of 1:1.25. After rolling of fluorine-containing elastomer, magnesium oxide, barium sulfate, calcium fluoride and impact detonation diamond graphite are successively added within 3 or 4 minute intervals. EFFECT: increased abrasive wear resistance of vulcanizate and resistance thereof to heat aging. 3 tbl
