Resin composition for sliding parts and sliding parts using with the same composition

Abstract

A resin composition for a sliding member, comprises from 0.1 to less than 1.0% by weight of a fatty acid, 0.1 to 2.0% by weight of a metallic soap, 0.1 to 2.0% by weight of a phosphate, 0.3 to 2.0% by weight of a lubricating oil, and a polyester-based elastomer as the balance. A sliding member produced from such resin composition exhibits excellent friction and wear characteristics even at a low sliding speed under a high load.

Description

technical field [0001] The present invention relates to a resin composition for sliding parts and a sliding part manufactured from the resin composition, and more particularly, to a resin composition for sliding parts showing excellent frictional properties and wear properties even under low sliding speed and high load. A resin composition, and a sliding part manufactured from the resin composition. Background technique [0002] Various synthetic resin sliding members made of thermoplastic synthetic resin blended with lubricating oil are generally recommended, which are enhanced in self-lubricating performance and wear resistance, and can withstand long-term use without adding oil therein. [0003] For example, inventions such as Japanese Patent Publication Nos. 46-5321 (1971), 46-42217 (1971) and 47-42615 (1972) relate to methods of manufacturing sliding parts from polyacetal resins containing lubricating oil. These patents disclose the use of The polyacetal resin is impre...

[0005] Although a sliding member made of the synthetic resin composition described in Japanese Patent Laid-Open Publication No. 62-45662 (1987) can exhibit excellent friction and wear properties, it is found that when the sliding member is applied to a sliding part such as an automobile st
