ANTI-FRICTION POLYMER COMPOSITION Russian patent published in 2008 - IPC C08J5/16 C08L27/18 B82B1/00 C09K3/10

Abstract RU 2329279 C1

FIELD: chemistry.

SUBSTANCE: invention pertains to polymer composite materials for anti-frictional purposes, which can be used for making component parts of friction assemblies of machines and equipment. Description is given of the polymer composition, containing polytetrafluoroethylene and aluminium oxide with particle size of 9-11 nm as filler material, with the following ratio of components: nano-size aluminium oxide - 0.1-2.0 mass %, polytetrafluoroethylene constitutes the remaining percentage.

EFFECT: increased wear resistance, carrying capacity, reduction of coefficient of friction with retention of stress-strain properties of the composite material based on polytetrafluoroethylene.
