タール樹脂組成物に関するもρである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an oil-impregnated polyacetal resin composition with excellent lubricity for use as a material for sliding parts.
（従来の技術〕
ポリアセタール樹脂（以下ＰＯＭと略記す）は熱可塑性
樹脂として安価で大量生産が可能な上、機械強度にすぐ

耐摩耗性は比較的おだやかな摺動条件下では充分その用
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。(Conventional technology) Polyacetal 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 used in many mechanical parts such as bearings and gears instead of conventional metals. However, although POM's wear resistance is sufficient under relatively gentle sliding conditions, under harsh conditions such as high speeds and high loads, the coefficient of friction rapidly increases due to melting and seizing. It increases in size and wears out, making it unusable.

し、これらの材料においては耐摩耗性は改良されている
ものの、摩擦係数はすべて運転時間の経過にともなって
増加する傾向が見られる。また保持体として硬質の材料
を配合した含油ＰＯＭを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-impregnated POM used in these products generally contains carbon, activated carbon, polyethylene, fluororesin, etc. as an oil retainer, which prevents separation of lubricating oil during kneading or molding, and improves lubricating properties. I'm trying. 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.
以上述べたように、従来の技術においては、摩擦係数が
低い値で安定し、摩耗係数も小さく、しかも軟質相手材
を損傷しない材料は得られないという問題があり、これ
を解決することが課題であった。As mentioned above, in the conventional technology, there is a problem that it is not possible to obtain a material that has a stable friction coefficient at a low value, a small wear coefficient, and does not damage the soft mating material, and it is an issue to solve this problem. Met.
上記の課題を解決するために、この発明はポリアセター
ル樹脂に、四フン化エチレン樹脂を全樹脂組成物に対し
て５〜２５重量％、タルクを５〜２５重世％、エステル
油を２〜ＩＯ重量％配合して潤滑性に優れた含油ポリア
セタール樹脂組成物とする手段を採用したものである。In order to solve the above problems, this invention adds 5 to 25% by weight of tetrafluoroethylene resin to the total resin composition, 5 to 25 weight% of talc, and 2 to IO of ester oil to the polyacetal resin. This method adopts a method of blending the oil-containing polyacetal resin composition in an amount of % by weight to obtain an oil-impregnated polyacetal resin composition with excellent lubricity.
以下その詳細をのべる。The details are below.
まず、この発明に使用するＰＯ？ｌとはポリオキシメチ
レンホモポリマーまたは主鎖の大部分がオキシメチレン

It is also possible to add known antioxidants, antioxidants, reinforcing agents, solid lubricants, etc. to POMI.
つぎに、この発明に使用する四フッ化エチレン樹脂は、
四フン化エチレンの重合体であり、成形用の粉末であっ
ても、また、いわゆる固体潤滑剤用の微粉末のいずれで
あってもよいが、市販の粉末を、たとえば３００°Ｃ以
上の温度で加熱するなどの熱処理をしたものは成形時に
金型へのデポジントが少なく好ましい。Next, the tetrafluoroethylene resin used in this invention is
It is a polymer of tetrafluoroethylene, and it can be either a powder for molding or a fine powder for so-called solid lubricants. Those that have been heat-treated, such as heating at a temperature, are preferable because there is less deposit on the mold during molding.
また、この発明に使用するタルクは、マグネシウムのケ
イ酸塩である。Further, the talc used in this invention is a magnesium silicate.
さらに、この発明に使用するエステル油としては、脂肪
酸のグリセリンエステルである天然油脂、三塩基性酸の
アルコールエステルであるジエステル、ネオペンチルポ
リオールの脂肪酸エステルであるポリオールエステル、
芳香族エステル等広く市販のエステル油の中から選定し

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 tribasic 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ン
化エチレン樹脂を５〜２５重看％配合する理由は、５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重債％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。また、タルクを５〜２５重量％配合する理由は
、５重量％未満では摩擦係数を低い値で安定化できない
からであり、２５重量％を越えると摩耗特性が悪化する
からである。さらに、エステル油を２〜ＩＯ重量％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、１０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 the tetrafluorinated ethylene resin is blended at 5 to 25% by weight based on the total resin composition is that if the amount is less than 5% by weight, the oil cannot be retained sufficiently and the oil will separate. This is because if the amount exceeds 25%, the mechanical properties will be significantly reduced and injection moldability will be impaired. Further, the reason why 5 to 25% by weight of talc is blended is that if it is less than 5% by weight, the coefficient of friction cannot be stabilized at a low value, and if it exceeds 25% by weight, the wear characteristics deteriorate. Furthermore, the reason why 2 to IO weight % of ester oil is blended is that if it is less than 2 weight %, a sufficient lubricating effect cannot be obtained, and if it exceeds 10 weight %, oil separation during molding will result in loss of stability during molding. This is because you will be exposed.

Tetrafluoroethylene resin and talc dispersed in the polyacetal resin provide lubricity as a solid lubricant and at the same time act as a retainer for the ester oil, uniformly dispersing the oil and preventing separation. The ester oil is supplied to the sliding surface and plays the role of a lubricant, and the talc stabilizes the coefficient of friction at a low value, unlike conventional oil-containing PO? It is considered that all the shortcomings of 1 will be eliminated.

めて大きい。(Effects) As described above, the oil-containing polyacetal resin composition of the present invention is excellent in molding stability during injection molding processing, molding surface texture, and *abrasion characteristics. It can also be used for sliding parts such as bearings, gears, sliders, etc. that are used under harsh conditions where the coefficient is too high to use.Furthermore, the oil-impregnated polyacetal resin composition of this invention is originally white in color. Therefore, it also has the advantage that it can be colored arbitrarily by adding a pigment.Therefore, the significance of this invention is extremely large.
