関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a lubricating composition containing polyphenylene sulfide resin as a main component and used as a material for various sliding parts.
近年、合成樹脂滑り軸受の用途分野が拡大するにつれて
、軸受の使用条件、特に高温雰囲気下において、良好な
摩擦摩耗特性を発揮するような耐熱性のある合成樹脂製
軸受が強く要望されるようになってきた。In recent years, as the field of application for synthetic resin plain bearings has expanded, there has been a strong demand for heat-resistant synthetic resin bearings that exhibit good friction and wear characteristics under the conditions in which the bearings are used, especially in high-temperature environments. It has become.
また、軸受の相手材としても安価なアルミニウム合金A
3056等が使用されており、使用中に相手材を傷つけ
ないような軸受の特性が要求されている。In addition, aluminum alloy A is inexpensive as a mating material for bearings.
3056 etc. are used, and the bearing is required to have characteristics that will not damage the mating material during use.

かし、このPPS樹脂は自己潤滑性が乏しいため、潤滑
性を必要とする部分の材料として使用するに際しては、
潤滑剤などを添加して別途潤滑性を付与しなければなら
ない。It is well known that polyphenylene sulfide (abbreviated as PPS) resin has been used as a thermoplastic synthetic resin with good heat resistance and mechanical strength. However, this PPS resin has poor self-lubricating properties, so when using it as a material for parts that require lubricity,
Lubricating properties must be provided separately by adding a lubricant or the like.
そこで、このようなPPS樹脂に、たとえば黒鉛、四フ

好な摩擦摩耗特性を発揮させるという点で決して充分で
あるとは言えない。Therefore, composite materials have been developed in which graphite, tetrafluoroethylene resin, lubricating oil, metal oxides, aromatic polyamide resins, and the like are added to such PPS resins. However, such composite materials cannot be said to be sufficient in terms of exhibiting very good friction and wear characteristics under high temperature and high load conditions.

Composite materials containing synthetic resin powder, which is more heat resistant than resin, have also been developed, but if the other material is a hard material,
Although it exhibits good friction and wear characteristics, if the mating material is an aluminum alloy, it will damage the mating material. On the other hand, a composite material containing carbon fibers exhibits good friction and wear characteristics in the initial stage, but even if the mating material is hard, it damages the mating material, and as the material is damaged, the friction and wear characteristics rapidly deteriorate.

問題点があり、これを解決することが課題となっていた
。As described above, the conventional technology has the problem that it cannot meet the demands of the public because there is no heat-resistant material with good lubrication properties, and it has been an issue to solve this problem.
(課題を解決するための手段〕
上記の課題を解決するために、この発明は、PPS樹脂

用できる。First, the PPS resin in this invention is a synthetic resin represented by the formula -C. Here, in the formula, -ph-, Q is a halogen of F, CI, Br, or CI+3, and m represents an integer of 1 to 4. Among these, it is commercially available from Philips Vetroleum Company of the United States under the trademark "Rydon", and its manufacturing method is described in U.S. Patent No. 3,354,129 (corresponding patent No.
No. 3368). According to it, Rydon is heated at 160-250°C in N-methylpyrrolidone solvent.
1 Manufactured by reacting p~dichlorohenzene with sodium disulfide under pressurized conditions, and post-heat treatment of resins with various degrees of polymerization, ranging from those with no cross-linking to those with partial cross-linking. Since it can be manufactured freely through various processes, it is possible to arbitrarily select and use a solvent having appropriate melt viscosity characteristics for the desired solvent blend. Moreover, a linear one without a crosslinked structure can also be used.

、好ましくは0.5〜60μmのものである。Moreover, the talc in this invention is a hydrous silicate of magnesium, and is preferably in the form of powder, scale, or fiber. In addition, these particle sizes range from 0.1 to 100 pva
, preferably 0.5 to 60 μm.
なお、この発明において、フッ素樹脂の量を5〜40重
世%に限定する理由は5重量%より少ないと潤滑特性が

定する理由は、この範囲外では潤滑特性が悪く、30重
量%を越えると極端にもろくなるからである。In this invention, the reason why the amount of fluororesin is limited to 5 to 40% by weight is that if it is less than 5% by weight, the lubricating properties will be poor, and if it exceeds 40% by weight, the moldability will be significantly impaired. Further, the reason why the amount of talc is limited to 5 to 30% by weight is that outside this range, the lubricating properties are poor, and if it exceeds 30% by weight, it becomes extremely brittle.

なった。From the results shown in Table 2, in Comparative Examples 1 to 5, the amount of wear and rotational torque were large, and Comparative Examples 1 and 2
In cases 5 and 5, the damage to the mating material was large. On the other hand, in Examples 1 to 4, both the amount of wear and rotational torque were small, and it was revealed that the aluminum alloy of the mating material was not damaged.
