METHOD OF PRODUCING FRICTIONAL POLYMER MATERIALS Russian patent published in 2011 - IPC C08J5/14 C08L9/00 C08L9/02 C08L63/00 C08K3/06 C08K5/40 C08K5/47 

FIELD: chemistry.

SUBSTANCE: method involves pretreatment of butadiene or butadiene nitrile rubber on plasticising equipment with further addition of vulcanising agents - sulphur, thiuram, 2-mercaptobenzothiazole, and then powdered filler, fibrous filler saturated with water-soluble epoxy resin, which is a product of the reaction of a mixture of diane and aliphatic resin with glycols or derivatives thereof. The ratio of the fibre to resin ranges from 95-5 to 60-40. A special additive of 1-5% emulsion of a liquid transition metal carbonyl in triethanolamine is then added. The material contains the following in pts.wt: rubber 100, sulphur 1-15, thiuram 0.04-0.2, 2-mercaptobenzothiazole 0.3-4.0, powdered filler 10-100, saturated fibrous filler 15-1000, metal carbonyl emulsion 0.5-10.0.

EFFECT: invention improves strength properties and wear resistance of frictional polymer materials, improves labour conditions when mixing components.
