FRICTIONAL POLYMER MATERIAL Russian patent published in 2010 - IPC C08L61/10 C08K13/02 C08J5/14 

FIELD: chemistry.

SUBSTANCE: material is in form of a composition which contains binder (A) in form of rubber which is pre-treated on rollers with a product of reaction of epoxy diane resin with M.M 400-1200 with methacrylic acid on epoxy groups while using methacrylic acid in stoichiometric amount of 0.3-0.8 in the presence of a catalyst - methylimidazole 0.05-1.0 pts. wt per 100 pts. wt of reacting components (B) in weight ratio A:B between 96:4 and 60:40, and the vulcanising agent used is alkylphenol-formaldehyde resin and a mixture of metal oxides in ratio TiO₂:V₂O₅:WO₃ between 1:2:2 and 2:1:1 in the following ratio of components, pts. wt: said binder 100, alkylphenol-formaldehyde resin 5-20, powder filler 100-400, fibre filler 50-200, mixture of metal oxides 3-20.

EFFECT: higher heat resistance, strength and service life of frictional material and longevity of metal article in contact with said material.
