Abstract:
1. A sliding resin composition comprising a synthetic resin containing PTFE as a solid lubricant and a particulate PTFE film forming agent wherein the PTFE is dispersed in the form of particles in the synthetic resin, the PTFE film forming agent is embedded in the surface of particles of the PTFE particles, the PTFE film forming agent has an area ratio on the surface of particles of the PTFE in the range of 5-30%, the PTFE is contained in an amount of 10-40 mass % based on the sliding resin composition, the PTFE film forming agent is contained in an amount of 5-15 mass % based on the sliding resin composition, and the PTFE film forming agent is at least one of inorganic compounds selected from the group consisting of calcium phosphate, barium phosphate, magnesium phosphate, lithium phosphate, lithium tertiary phosphate, calcium tertiary phosphate, calcium hydrogenphosphate or anhydride thereof, magnesium hydrogenphosphate or anhydride thereof, lithium pyrophosphate, calcium pyrophosphate, magnesium pyrophosphate, lithium metaphosphate, calcium metaphosphate, magnesium metaphosphate, lithium carbonate, magnesium carbonate, calcium carbonate, strontium carbonate, barium carbonate, calcium sulfate, and barium sulfate.
