RUBBER MIXTURE BASED ON FLUORORUBBERS Russian patent published in 2015 - IPC C08L27/16 C08L27/20 B82B3/00 C08K3/04 C08K3/22 C08K5/13 C08K5/14 C08K5/17 C08K5/5317 

FIELD: chemistry.

SUBSTANCE: rubber mixture contains copolymer of vinylidenefluoride and chlorotrifluoroethylene and triple copolymer of vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene with 0.3 wt % of functional group of bromine, magnesium oxide and calcium hydroxide as vulcanisation activator and technical carbon T-900. Mixture also contains zinc oxide as activator of vulcanisation of peroxide vulcanising system, perkadox 14-40B-GR and triallylisocyanurate as vulcanising agent of peroxide vulcanising system, bisphenol AF and benzyltriphenylphosphonium chloride as vulcanising agent of bisphenol vulcanising system, as well as rofamin T and stearic acid as technological additive.

EFFECT: invention makes it possible to achieve specified tensile elongation, reduce change of weight of sample of medium - liquid B after impact within 72 h, increase plasticity, give rubber mixture specified framing in production of non-moulded and calendered mechanical rubber products.
