【発明の詳細な説明】
本発明は優れた摺動特性を有するポリイミド樹脂組成物
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polyimide resin composition having excellent sliding properties.
［従来の技術］
ポリイミド樹脂は機械的、化学的、摺動特性および熱的
性質に優れたエンジニアリングプラスチノクであること
より、電気・電子機器、機械、自動車等の用途に種々使
用されている。[Prior Art] Polyimide resin is an engineering plastic with excellent mechanical, chemical, sliding properties, and thermal properties, and is therefore used in a variety of applications such as electrical and electronic equipment, machinery, and automobiles.
しかし最近の技術の進歩により、ポリイミド樹脂が有す
る特性、特に摺動特性を一段と高めたものが要求される
ようになってきた。ポリイミド樹脂はこのような耐熱性

イミド樹脂単独では自己潤滑性および耐摩耗性の点で十
分でない。However, with recent advances in technology, there has been a demand for polyimide resins with even higher properties, especially sliding properties. Polyimide resins are considered to be applied to sliding members that take advantage of their heat resistance, but polyimide resins alone do not have sufficient self-lubricating properties and wear resistance.
一般にプラスチックの自己潤滑性、耐摩耗性などの摺動
特性の向上方法としては、固体潤滑剤の配合、四フッ化
エチレン樹脂の配合、潤滑油の配合等が知られており、

十分でない。さらに潤滑油を分散含有させたものにおい
ても他の物体に接着させたり、被着させて使用するよう
な場合には含油性であるために、かえって悪影響を及ぼ
すことがある。In general, methods for improving the sliding properties such as self-lubricating properties and wear resistance of plastics include blending solid lubricants, blending tetrafluoroethylene resin, blending lubricating oil, etc.
For example, JP-A-56-61458, JP-A-55-1
The technique is disclosed in Japanese Patent Publication No. 35163, Japanese Patent Publication No. 47-42615, Japanese Patent Publication No. 5321-1974, and the like. However, when a solid lubricant is added, hardly any improvement in load resistance can be expected. In addition, products containing resins with a low coefficient of friction such as tetrafluoroethylene resin can be expected to have a considerable effect on improving self-lubricity, but on the other hand, the mechanical strength and load bearing capacity of the molded product will inevitably decrease, and the Abrasion resistance is also not sufficient. Furthermore, even if lubricating oil is dispersed therein, if it is used by adhering or coating it on other objects, it may have an adverse effect because it is oil-impregnated.
本発明の目的は、ポリイミド樹脂の摺動特性を改良した
樹脂組成物を提供することにある。An object of the present invention is to provide a resin composition with improved sliding properties of polyimide resin.
本発明者らは前記の目的を達成するために、鋭意検討し
た結果、フッ素樹脂と共に芳香族ポリアミド樹脂を配合
することに自己潤滑性、耐摩耗性などの摺動特性が顕著
に改良されることを見出し本発明に到達した。In order to achieve the above object, the inventors of the present invention have made extensive studies and found that mixing an aromatic polyamide resin with a fluororesin significantly improves sliding properties such as self-lubricating properties and wear resistance. This discovery led to the present invention.

F) Among the above-mentioned fluororesins, completely fluorinated tetrafluoroethylene resin (PTFE) has particularly excellent properties and is therefore most preferably used in the present invention. The amount of these fluororesins added in the present invention is in the range of 3 to 60 parts by weight per 100 parts by weight of the above-mentioned polyimide resin. If the amount of the fluorine resin added is less than 3 parts by weight, the effect of improving the self-lubricity of the resulting resin composition will be small, which is not preferable. In addition, the amount of fluorine resin added is 60
If the amount is more than 1 part by weight, the resulting resin composition will have poor mechanical properties and moldability, which is not preferable. The preferred amount added is 10 to 50 parts by weight. Further, the aromatic polyamide resin used in combination in the present invention is a relatively newly developed heat-resistant resin, and is expected to be used in various fields by taking advantage of its many unique properties. For example, typical examples include those having the following structural formulas, and at least one kind or a mixture of two or more of these can be used.
