ANTIFRICTION COMPOSITION Russian patent published in 2008 - IPC C09D127/18 C09D5/08 C08L27/18

Abstract RU 2323240 C2

FIELD: antifriction materials.

SUBSTANCE: invention relates to antifriction compositions based on soluble fluoropolymers that can be used to coat surfaces of piston rings, sealing rings, ring gaskets, collars, and other antifriction rubber parts used in friction units of machines in instrument engineering, chemical machinery construction, automobile industry, and aircraft industry. Antifriction composition described in invention comprises soluble tetrafluoroethylene/vinylidene fluoride copolymer, organic solvents: acetone, ethylacetate, cyclohexanone, and amyl acetate, low-molecular weight epoxy dian resin ED-8 or ED-10, amine hardener (product of condensation of formaldehyde and phenol with ethylenediamine AF-2), diluent (ethyl cellosolve), and, additionally, filler: graphite or molybdenum disulfide.

EFFECT: increased wear resistance and durability of rubber sealing members.
