ましい。(Prior Art) Conventionally, many sliding parts such as bearings, gears, and cams have been used in electronic/electrical parts and machines. As these materials,
Recently, plastic materials have been attracting attention as an alternative to metal materials. However, although plastic materials are lightweight and have high productivity, they are inferior in rigidity and heat resistance compared to metal parts, and are difficult to injection mold with good dimensional accuracy. It has the disadvantage that it is larger than other metal parts. Therefore, when using plastic materials, in addition to being excellent in mechanical strength such as rigidity, heat resistance, dimensional accuracy, etc., it has a low coefficient of friction resistance, a small amount of wear, and a limit pv value (a certain surface pressure (P)). It is desirable to use a material that has excellent sliding characteristics and has a high peripheral speed (V), which is the limit value of the load at which the material deforms or seizes when it exceeds it.

ではない。Conventional thermoplastic resins that are relatively heat resistant include polyamide resin, polycarbonate resin, and polyethersulfone resin, but polyamide resin has a high water absorption rate, so it has the disadvantage of poor dimensional stability of molded products. ,
Poor quality polycarbonate resin has a high coefficient of friction and is difficult to use in an atmosphere around 150°C. Also,
Polyether sulfone resins reinforced with glass fibers are difficult to mold and have high anisotropy and water absorption, making them unsuitable for use as sliding members in terms of precision moldability (warpage) and dimensional stability. On the other hand, polyphenylene sulfide resin (hereinafter referred to as PPS) is attracting attention as a thermoplastic resin that has higher heat resistance and excellent mechanical strength than the above-mentioned resins. However, PPS is still unsatisfactory as a sliding member because of its large mold shrinkage rate and anisotropy, or its insufficient rigidity in a high-temperature atmosphere around 150°C.

The material was mixed with at least one lubricant selected from fluorocarbon polymer, high molecular weight polyethylene powder, molybdenum disulfide, graphite, and lubricating oil in a Henschel mixer to obtain a powdered resin composition. Next, this composition was melted and mixed using a conventional single-screw extruder at a cylinder temperature of 320° C., and then cut into 3 mm lengths using a pelletizer to form pellets. The obtained pellet throat was molded using an in-line screw injection molding machine at a cylinder temperature of 280 to 320°C and a mold temperature of 15°C.
0°C1 injection pressure (primary pressure) 1400 kg/cm", holding pressure (secondary pressure) 500 kg/cm", and injection speed were set at high speed, and test pieces for evaluating material properties and test pieces for evaluating wear characteristics were molded. Material properties such as mechanical strength and sliding properties were measured. The friction and wear test was conducted using a normal friction and wear tester, using cylindrical hard steel (845C) as the mating material, and in a non-lubricated state. In this case, the test was conducted by fixing the friction velocity (V) at 20 m/min and changing the surface pressure (P) every 10 minutes. The dynamic friction coefficient detects the friction force at each PV value with a load cell directly connected to the torque lever.
It was measured and determined. The limit PV value was determined at the time when it became impossible to control the surface pressure. The rate of wear loss is determined by the PV value of 12
The weight difference (mg) before and after the test was determined by operating the tester for up to 00 kg/cm"-m7 minutes, and the value obtained by dividing that weight difference by the cumulative PV value x time, that is, the steady wear amount (mg/kg/cm")

At the same time, in terms of sliding properties, the friction coefficient and steady wear amount are small, and the limit PV value is large. Therefore, these compositions are extremely suitable as resin compositions for mechanical parts having sliding properties. Further, even when a block copolymer resin blended with a small amount of PPS or polysulfone is used for the base material (Examples 4 and 5), the above material properties and sliding properties are excellent in a well-balanced manner. However, the base material is PPS
When used alone (Comparative Example 1), the dimensional accuracy is inferior to block copolymer resins, and when polyether sulfone is used alone (Comparative Example 2), it has difficulty in moldability, and has poor heat resistance and mechanical properties. It has poor strength and dimensional accuracy, and is not suitable as a sliding material in either case. In addition, when heat-resistant fibers are not blended (Comparative Example 3) or when additives are not blended (
Comparative Example 4) has extremely poor sliding properties due to insufficient mechanical strength and heat resistance, or has insufficient properties, and cannot be used as a sliding member.
