ELECTRICALLY CONDUCTIVE SLIDING MATERIAL COMPOSITION

摘要

PURPOSE:To provide the titled compsn. which gives moldings which have a low coefficient of friction inherent to tetrafluoroethylene resin and electrical conductivity imparted thereto while retaining wear resistance, by adding a mixture of an Ni-coated solid lubricant and a carbon fiber to tetra-fluoroethylene resin. CONSTITUTION:An electrically conductive sliding material compsn. is obtd. by adding 30-150pts.vol. mixture of an Ni-coated solid lubricant (e.g. mica or graphite coated with Ni by electroless plating) and a carbon fiber in a vol. ratio of 15:80-80:20 to 100pts.vol. tetrafluoroethylene resin. Since moldings obtd. from the compsn. has a low coefficient of friction inherent to the tetrafluoroethylene resin and electrical conductivity imparted thereto while retaining excellent wear resistance by the addition of the Ni-coated material and the carbon fiber, they are particularly suitable for use as bearing materials which require both wear resistance and electrical conductivity.
