Definitions

  • soft glasses such as lead and/or soda-lead glass particles are incorporated into PTFE powder in amounts ranging from 13.2 to 74.3 weight percent for lead glass and 6.4 to 56.5 weight percent soda-lead glass. This corresponds to 5 to 50 volume percent lead glass and soda-lead glass, respectively in the final sintered PTFE.
  • the fabrication of various articles from the PTFE powder/soft glass solids blend is carried out by conventional PTFE processing involving cold compression followed by sinter ⁇ ing at elevated temperature.
  • the sintering temperature in accordance with another aspect of the invention is maintained at or above the annealing point of the glass particles in the case of lead glasses.
  • PTFE filled with lead or soda-lead glass is sintered at tem ⁇ peratures above the melting point of lead in an oxygen free atmosphere wherein at least a portion of the lead oxide present in lead glass is reduced to metallic lead.
  • Such treatment allows generation of metallic lead during the sintering step which can be allowed to migrate within the PTFE to form localized areas rich in lead or gradients of varying metallic lead concentrations within the PTFE at various locations.
  • the polytetrafluoroethylene (PTFE) composite compounds in accordance with the present invention have a wide variety of uses.
  • the compounds of the invention may be fabricated into bushings, rider rings, and seals for use in compressors, hydraulic equipment and auto ⁇ mobiles. Further, the compounds may be used to form bearing pads for bridges, pipe lines and high-rise buildings.
  • PTFE any of the commercially available brands of PTFE may be used to make th PTFE composite.
  • PTFE available from E. I. Dupont Co. and sold as TEFLON may be used.
  • PTFE sold as HALON by Allied Corp., FLUON by ICI Americas, Inc. and HOSTAFLON by American Hoechst may be used.
  • the PTFE is preferably purchased as a powder having average particle sizes ranging from approximately 0.2 microns to 5 microns and even larger.
  • the amount of glass filler particles incorporated into the PTFE powder is sufficient to provide sintered PTFE which contains between 5 volume percent and 50 volume percent glass particles.
  • the amount of lead glass filler particles will range from 20 to 50 weight percent while the amounts of soda-lead glass preferably range from 10 to 30 weight percent.
  • the above weight percent ranges for the lead and soda-lead glasses are different due to differences in the densities of the glass.
  • the given weight percentage ranges are designed to provide roughly equivalent preferred volume percent ranges for the two types of glasses.
  • soft glass filled PTFE were prepared using TEFLON TFE 7A powder and Corning No. 8463 high lead glass particles and Corning No. 0010 soda-lead glass particles. The glass particles were fractured and crushed sufficiently to pass through a 325 mesh screen (U.S. standard size). The TEFLON powder and glass particles were mixed to provide the following solids blends: (1) 25 weight percent high lead glass in PTFE
  • the 710°F sintering temperature used in the fabrication of the soft glass loaded PTFE exemplary rods is, as previously mentioned, above both the 685°F annealing point of the high lead glass and the 621°F melting point of lead. Some lead melted out of the high lead glass filler particj.es. The melted lead formed in the center of the rods and on cooling a dark colored center core was formed by lead solidifying in the interstices of the central portion of the rod. As previously mentioned, this phenomena can be controlled by regulating the oxygen content of the sintering oven atmosphere and/or reducing sintering temperature.
  • the soft glass filled PTFE in accordance with the present invention provides an improved compound which is structurally stronger than conventional PTFE composite materials made from PTFE filled withe E-Glass and further provides significant reductions in wear debris generated when the PTFE filled with soft glass is used in place of E-Glass/PTFE composite.
  • Seals and rider rings were made from both the PTFE filled with 25 weight percent high glass and PTFE filled with 15 weight percent chopped E-Glass fibers.
  • the E-Glass fibers were .0005 inch in diameter and .005 inch long. These seals and rider rings were assembled in cryo-cooler compressor units and their performance observed.
  • the performance of the PTFE filled with soft glass was equal to or surpassed the performance of the PTFE seals and rings filled with E-Glass.
  • the amount of wear debris generated by the PTFE seals and rings filled with soft glass was significantly less than that generated by the PTFE filled with E-Glass.
