-High heat resistance as seen in descriptions such as 90296,
It is known to have flame resistance, mechanical and electrical properties, chemical resistance, and hydrolysis resistance. Taking advantage of these excellent properties, it has been suggested that they can be used as insulating coatings for electric wires and cables and as flexible printed circuit boards, but they are also used not only in the electronic and electrical fields, mechanical fields, aircraft fields, automobile fields, and hot water fields. It is expected that they will expand into various industrial fields such as

A combination of these has been used, but recently plastics, especially heat-resistant plastics, have come into widespread use in terms of weight reduction and productivity. This tendency is especially strong in the automobile industry, which has been growing rapidly, and in the field of office equipment such as copying machines, typewriters, and computers. In addition, in terms of function, these outbuildings are required to be used under very harsh conditions such as no lubrication and high speed, so the sliding parts used in these applications, such as sliding bearings, sliders, gears, and cams, are In addition to excellent sliding properties, high functionality such as high mechanical strength and heat distortion temperature is required. For example, in plain bearings,
Characteristics such as a critical PV value of < 0 and excellent dimensional stability are required, and for sliders, gears, cams, etc., it is required to have mechanical strength, low heat deformation temperature, and excellent lubricity and dimensional stability. Characteristics such as being present are required. The limit PV value here is used as a guideline when plastic is applied to sliding bearings, etc. Due to the generation of friction heat on the sliding end surface, the temperature rises significantly and the plastic softens. It is the product of the pressure P applied to the bearing, which is the limit at which normal frictional motion cannot continue due to melting, chemical decomposition, etc., and the sliding speed (2).

ことはむつかしい。Thermoplastic aromatic polyetherketone resin has the highest melting point among thermoplastic resins at 884°C, and
Since gJIT can be injection molded, it can be expected to be useful in the above fields by adding fluorocarbon polymer, preferably polytetrafluoroethylene, to the resin to impart lubricity. is about 40
Since the resin has a glass transition point as low as 148°C, the composition containing the fluorocarbon polymer has a
The thermal deformation temperature is approximately 160°C, and if the temperature exceeds this temperature, the mechanical strength will decrease significantly and the dimensional stability will deteriorate, and when the composition is used as a sliding bearing, etc.
- only a low limit pv value can be obtained, and the range of application is rather limited. Furthermore, even when applied to various sliders, gears, and cams, it is difficult to use them in high-temperature atmospheres exceeding 150°C.

し本発明に至った。The inventors of the present invention have focused on the above-mentioned problems, and as a result of intensive study,
Thermoplastic aromatic polyetherketone I! To tllllt,
By further containing aromatic polyamide fibers in a composition containing a fluorocarbon polymer, the limit pv value, mechanical strength, and heat resistance (heat distortion temperature) are significantly improved compared to the composition. The present invention was based on the discovery that the range of application can be expanded as a sliding material for oil bearings, sliders, gears, cams, etc.

した固有粘度のことである。The aromatic polyetherketone used in the present invention contains repeating units together with other repeating units and has an intrinsic viscosity of 0.7 to 2.6 or less, preferably 0.8 to 1.8. The polymer may contain less than 26% by weight of other repeating units, but a polymer containing more than 25% by weight is not preferred because the inherent properties of the polyetherketone are lost. Further, the intrinsic viscosity is the intrinsic viscosity measured for a composite melt in concentrated sulfuric acid having a density of 1.84 f/- containing 0.1 F of the electrical composite per 100 mm of solution.

This specific value (9) is a value that uniquely corresponds to the molecular type of the polymer. Further, the polyetherketone having a viscosity of less than 0.7 has low heat resistance, and even if a molded article is obtained, it is extremely brittle. On the other hand, if it exceeds 2.6, the melt viscosity is too high and the processability is poor, making it generally unusable.

、均一組成物が得られない。As a blending example, thermoplastic aromatic polyether ketone resin 95-80% by weight, fluorocarbon polymer 2.5-80% by weight.
It is effective to mix 60% by weight of aromatic polyamide fibers and 2.5 to 60% by weight of aromatic polyamide fibers (the total amount of fluorocarbon polymer and aromatic polyamide fibers is 5 to 70% by weight of the total resin composition). That is, when the total amount of fluorocarbon polymer and aromatic polyamide fiber exceeds 70% by weight of the resin composition and the amount of thermoplastic aromatic polyetherketone resin is less than 80% by weight, the mixing is insufficient. Yes, uniform composition I! +171 is not obtained, the fluidity of the resin composition is lost, and molding becomes difficult. In addition, the total amount of fluorocarbon polymer and aromatic polyamide fiber is 5 coul%.
If it is less than that, sufficient sliding properties, mechanical strength, and heat distortion temperature cannot be obtained. Furthermore, even if the total amount of fluorocarbon polymer and aromatic polyamide fiber is 5 to 70% by weight, if the amount of fluorocarbon polymer is less than 2.5% by weight and 1% by weight, the lubricity will be insufficient, and 60% by weight. If it exceeds this range, dispersibility and compatibility will decrease and it will be difficult to obtain a uniform composition. On the other hand, if the amount of aromatic polyamide fiber is less than 2.5% by weight, the limit P
There is no effect of improving the v value, and there is almost no improvement in mechanical strength or heat distortion temperature, and when it exceeds 60% by weight, the bulk density of thermoplastic aromatic polyether ketone resin and aromatic polyamide fiber becomes significant. As a result, mixing becomes insufficient, making the compounding process difficult and making it impossible to obtain a uniform composition.

できる。The resin composition of the present invention further contains a solid lubricant such as graphite or molybdenum disulfide to improve lubricity, and a crystalline heat-resistant resin such as oxybenzoyl polyester to improve wear resistance. As a mixing method for obtaining the resin composition of the present invention, the thermoplastic aromatic polyetherketone resin, the fluorocarbon polymer, and the aromatic polyamide fiber are mixed in a mixing machine such as a Henschel mixer or a super mixer. A common method is to tri-blend the mixture, then melt-knead it using a single-screw or multi-screw extruder, extrude the strands, and pelletize them using a cutter. In addition, when using roving as aromatic polyamide fiber, feed the roving from the bend groove of the extruder so that it has an appropriate blending ratio with the aromatic polyetherketone resin and fluorocarbon polymer fed from the hopper. It is preferable to take a method that adjusts the speed. Furthermore, sliding parts such as bearings and sliders can be easily obtained from the composition of the present invention by injection molding.

It is a suitable molding material for sliding members such as bearings, sliders, gears, cams, etc. that are used under certain conditions.

のため、射出成形困難であった。The system containing less than 2.5% by weight of fluorocarbon polymer ruts (Comparative Example 8) had poor head lubricity and had a high shore coefficient, so that only a very low limit PV value could be obtained. In addition, the total number of fluorocarbon polymers and polyamide fibers is 70%.
The system containing more than 11iIk% (Comparative Example 4) was difficult to injection mold due to insufficient ring fluidity.
