ANTIFRICTION COMPOSITION AND METHOD OF PREPARING SAID COMPOSITION Russian patent published in 2010 - IPC C08J5/16 C08L63/00 C08L61/10 C08K3/04 C08K3/08 F16C33/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of making large objects for antifriction purposes, particularly to antifriction filled compositions and can be used when making end seals of hydraulic turbines, spring bearings for ships etc. The composition contains the following in wt %: 43.5-50 carbon fabric with fibre with average crystal size on the basal plane equal to 3.0-6.0 nm and stacking distance of basal planes equal to 1.0-4.0 nm, 35.0-50.0 polymer thermoreactive binder and 1.0-15.0 of a product of reacting metal powder with fine-dispersed carbon particles with specific surface area of 110-150 m²/g, taken in volume ratio metal: carbon equal to 1:(0.01-0.15). The composition is obtained by mixing polymer thermoreactive binder with a product of reacting metal powder with fine-dispersed carbon particles with specific surface area of 110-150 m²/g, impregnation with binder which contains a suspension of the said product, carbon fabric and moulding.

EFFECT: invention increases crack resistance of the antifriction composition and simplifies the technology of preparing the composition.
