タール樹脂組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an oil-impregnated polyacetal resin composition with excellent lubricity for use as a material for sliding parts.
ポリアセタール４Ｍ脂（以下ＰＯＭと略記す）ば熱可塑

の用をなすが、高速、高荷重といった過酷な条件下では
溶融焼付による急激な摩擦係数の増大、摩耗の進行が起
こり使用に耐えなくなる。Polyacetal 4M resin (hereinafter abbreviated as POM) is a thermoplastic resin that can be mass-produced at low cost and has excellent mechanical strength, so it is being used in many mechanical parts such as bearings and gears instead of conventional metals. Became. However, Po1
The wear resistance of No. 1 is sufficient under relatively gentle sliding conditions, but under harsh conditions such as high speeds and high loads, the friction coefficient rapidly increases due to melting and seizure, and wear progresses, making it difficult to use. It disappears.

軟質の相手材と摺動させた場合、相手材を損傷する等数
多くの問題があった。Therefore, a method of adding and dispersing lubricating oil to POM to improve the wear resistance of POM is used for sliding parts such as bearings, gears, cams, and sliders. The oil-containing POM 4 used in these products generally contains carbon, activated carbon, etc. as an oil retainer to prevent separation of lubricating oil during kneading or molding, and to improve lubricating properties. However, although the wear resistance of these materials has been improved, the friction coefficients of all these materials tend to increase over time. Furthermore, when an oil-impregnated POM containing a hard material as a holder is allowed to slide against a soft mating material, there are many problems such as damage to the mating material.
そこで、軟質の相手材を傷つけない油の保持体として四

エチレン樹脂が堆積（モールドデポジット）シ、成形品
の表面に付着し外観を損ったり、寸法精度が悪化するな
ど、依然として多くの欠点があった。Therefore, tetrafluoroethylene resin was sometimes used as an oil retainer that would not damage the soft mating material. Although the lubricity of the composition was good, when injection molding the composition, tetrafluoroethylene resin was deposited on the mold (mold deposit) and the surface of the molded product. There were still many drawbacks, such as adhesion to the surface, damaging the appearance, and deteriorating dimensional accuracy.
このように、従来の技術においては、高速、高荷重とい

にも難点のないＰＯＭ ４よ得られていないという問題
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 has not been possible to obtain POM 4, which has excellent lubricity even under harsh conditions such as high speed and high load, and has no problems in formability. The challenge was to solve this problem.
上記の？ＩＭを解決するために、この発明はＰＯＭに、
成形用粉末を予め３００’Ｃ以上に熱処理し再び粉砕し

る手段を採用したものである。以下その詳細を述べる。above? In order to solve IM, this invention applies to POM,
The molding powder is heat-treated to 300'C or higher and re-pulverized to form a powder, made of polytetrafluoroethylene resin, which is a total resin &! The oil-containing POM is characterized by blending 3 to 25% by weight of POM and 2 to 10% by weight of ester oil. The details will be described below.
まず、この発明に使用するＰＯＭとはポリオキシメチレ

It is also possible to add known antioxidants, antioxidants, reinforcing agents, solid lubricants, etc. to POM.
つぎに、この発明に使用する四フッ化エチレン樹脂は、

Ｔ−４００等が挙げられる。Next, the tetrafluoroethylene resin used in this invention is
It is a polymer of tetrafluoroethylene, which is commercially available as a powder for bottom shapes, and is preferably heat-treated to 300"C or higher, solidified, and then crushed and re-pulverized.
The heat treatment may be carried out during molding or sintering of the tetrafluoroethylene resin. Commercially available tetrafluoroethylene resin powder that can be used in this invention is K manufactured by Kitamura Co., Ltd.
Examples include T-400.

が望ましい。Furthermore, the ester oils used in this invention include natural oils and fats that are glycerin esters of fatty acids, diesters that are alcohol esters of dibasic acids, polyol esters that are fatty acid esters of neopentyl polyol,
The ester oil can be selected from a wide variety of commercially available ester oils such as aromatic esters, but hindered esters such as polyol esters, which have excellent thermal and oxidative stability and lubricity, are preferred.
なお、この発明において、全樹脂組成物に対して四フフ
化エチレン樹脂を３〜２５重量％配合する理由は、３重
量％未満の少量では油を充分に保持できずに油が分離す
るからであり、２５重量％を越える多量では機械的特性
が著しく低下するとともに射出成形性が損われるからで
ある。さらに、エステル油°を２〜１ｏｆｉ１％配合す
る理由は、２重量％未満では充分な潤滑効果が得られず
、ＩＯ重量％を越えると成形加工時の油分離により成形
加工時の安定性が損われるからである。In addition, in this invention, the reason why 3 to 25% by weight of the tetrafluoroethylene resin is blended with respect to the total resin composition is that if the amount is less than 3% by weight, the oil cannot be retained sufficiently and the oil will separate. This is because if the amount exceeds 25% by weight, the mechanical properties will be significantly reduced and injection moldability will be impaired. Furthermore, the reason why ester oil ° is blended at 2 to 1% by weight is that if it is less than 2% by weight, a sufficient lubricating effect cannot be obtained, and if it exceeds IO weight%, the stability during molding will be impaired due to oil separation during molding. This is because you will be exposed.

The tetrafluoroethylene resin dispersed in the polyacetal resin provides lubricity as a solid lubricant and at the same time acts as a holder for the ester oil, making the oil uniformly dispersed and preventing separation. Ester oil is supplied to sliding surfaces and acts as a lubricant, achieving low friction and wear. Moreover, the tetrafluoroethylene resin does not accumulate on the mold during injection molding, the appearance of the molded surface is not impaired, and dimensional accuracy is maintained well, eliminating all the drawbacks of conventional oil-impregnated POM.
