Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、含油アセタール樹脂組成物に関する。[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to an oleoresinous acetal resin composition.
更に詳しくは、高荷重域における摺動特性を向上せしめ
た含油アセタール樹脂組成物に関する。More specifically, the present invention relates to an oil-containing acetal resin composition that has improved sliding properties in a high load range.
アセタール樹脂に油を含浸させた含油アセタール樹脂は
、一般に摺動特性にすぐれていることが知られている。Oil-impregnated acetal resins, which are acetal resins impregnated with oil, are generally known to have excellent sliding properties.

れをマスターバッチとしてアセタール樹脂とブレンドす
る方法あるいはアセタール樹脂の融点以上に加熱された
大過剰の油中でアセタール樹脂と混合し、その後冷却し
て沈殿させる方法などによって製造されている。Oil-impregnated acetal resin can be produced by directly impregnating the acetal resin with oil, by impregnating a resin with good compatibility with oil and then blending it with the acetal resin as a masterbatch, or by heating it above the melting point of the acetal resin. It is manufactured by mixing it with acetal resin in oil and then cooling and precipitating it.
しかしながら、これらの方法の白道も一般的な方法であ

られないのである。However, in the case of the method of adding liquid oil to the resin, which is a common method among these methods, if you try to knead the mixture of matrix resin and liquid oil using a screw extruder etc., it will stick to the matrix resin. Because of this oil, the oil slips at the hopper mouth of the extruder and is not absorbed into the extruder, resulting in virtually no oleoresin being obtained.
また、マスターバッチ法としては、平均分子量５０万以

なる。Furthermore, as a masterbatch method, a method is known in which a porous body produced by sintering ultra-high molecular weight polyethylene with an average molecular weight of 500,000 or more is impregnated with lubricating oil (Japanese Patent Publication No. 47-29374). Since acetal resin has no affinity with oil, when an oil-impregnated polyethylene sintered body is kneaded into acetal resin at a temperature of 190°C or higher, the oil separated from the sintered body has an affinity with oil. It will be dispersed in the acetal resin that does not have the desired sliding material.

−１１０，９７９号）。Therefore, the present applicant has previously proposed an oleoresin in which liquid oil is adsorbed on a porous styrene-divinylbenzene copolymer, and the acetal resin to which it is added does not have the above-mentioned drawbacks. (Patent application No. 62).

場合もあることがその後判明した。However, since the oleoresin composition prepared here contains a large amount of liquid oil, the acetal resin may become flexible depending on the type of oil, and the sliding properties may deteriorate in a high load range. found.
そこで、次にこれの対策についての検討を行なった結果

得られることを見出した。Therefore, as a result of considering countermeasures for this, it was found that even glass fiber, which is said to reduce the sliding characteristics for boat fishing, is effective if the filling amount is within a certain range. Therefore, it was discovered that by filling this inexpensive glass fiber, a material with excellent sliding properties even in a high load range could be obtained.
従って、本発明は含油アセタール樹脂組成物に係り、こ

Approximately 10 oleoresin with fluidity indicated by the following angle of repose
-30% by weight, about 2-10% by weight of glass fibers, and the remainder made up of acetal resin.
液状油を吸着させる多孔質スチレン−ジビニルベンゼン
共重合体は、ジビニルベンゼン部分がスチレン基体の架
橋点として作用する樹脂であり、見掛上細孔を有するも
のと有しないものとがある。The porous styrene-divinylbenzene copolymer that adsorbs liquid oil is a resin in which the divinylbenzene portion acts as a crosslinking point for the styrene base, and some have apparent pores and others do not.
これらの樹脂は、三菱化成工業製品ダイヤイオンとして

いる。These resins are commercially available as the Mitsubishi Chemical Industries product Diaion, but those with apparent pores (Diaion HP series) have a pore size of 16 to aooo and 0.
．． It has pores with a pore volume of 1+aQ/g or more, and although it has strong adsorption, the pore volume is large, so when a product sold with water completely in its pores is drained,
It is said that air enters the pores and does not come into contact with the liquid to be treated.

分に粘度約５〜７００００センチストークス（４０℃）
の液状油を吸着させることが行われる。In the oleoresin used in the present invention, as a precursor of the microporous ion exchange resin, powder or granules of such a water-containing synthetic adsorbent, which acts to adsorb and remove impurities in an aqueous solution, are used as a precursor of the microporous ion exchange resin. Approximately 3 to a temperature of 150℃
After heating for ~15 hours and completely drying, the pores have a viscosity of approximately 5~70,000 centistokes (40℃).
Adsorption of liquid oil is carried out.
その吸着を完全ならしめるために、液状油を有機溶剤溶

たる多孔質スチレン−ジビニルベンゼン共重合体粉体ま
たは粒体の細孔内の空気を追い出しながら浸透して行く
。In order to achieve complete adsorption, the liquid oil is first impregnated as an organic solvent solution, and the solution absorbs the air in the pores of the dry synthetic adsorbent, porous styrene-divinylbenzene copolymer powder or granules. It penetrates while expelling it.

の一種といえる。Furthermore, even copolymer resins that apparently do not have pores swell when immersed in an organic solvent such as toluene as described below, and when the state is observed using an electron microscope, it has been found that pores open. Therefore, such a copolymer resin can also be said to be a type of porous material.
このような細孔を利用して、共重合体樹脂に液状油を含
浸させることもできるが、そのままでは含浸速度が遅い
ため、上記の如く有機溶剤を利用し、膨潤により開いた
微細孔中に液状油を有機溶剤溶液として含浸せしめる方
法が好んで用いら九る。It is also possible to impregnate copolymer resin with liquid oil using such pores, but the impregnation rate is slow if it is left as is, so an organic solvent is used as described above to impregnate the copolymer resin into the micropores opened by swelling. A method of impregnating liquid oil as a solution in an organic solvent is preferably used.

共重合体中に吸着させ、含油樹脂を得る。After impregnation is performed by stirring the porous copolymer powder or granules in these organic solvent solutions, the organic solvent is evaporated and removed by heating to about 50 to 150°C and/or under reduced pressure, and the porous copolymer powder or granules are impregnated. An oleoresin is obtained by adsorbing oil in the copolymer in an amount less than the pore volume of the particle.
このようにして得られた含油樹脂は、例えば約１．１〜

また安息角で示される流動性試験方法（細用ミクロン製

、流動性の良好な樹脂である。The oleoresin obtained in this way has, for example, about 1.1 to
Although it shows a large oil content of 1.2 mQ/g, it does not stick to each other and shows a free flowing state.
In addition, it is a resin with good fluidity, showing an angle of repose of 45'' or less in a fluidity test method (using a micron powder tester).
即ち、安息角４５°以下では、多孔質体の細孔容積以下
の油が吸着されており、この状態ではアセタール樹脂の
粉体または粒体との混合、分散が容易となる。That is, when the angle of repose is 45° or less, oil is adsorbed in an amount less than the pore volume of the porous body, and in this state, it is easy to mix and disperse the acetal resin powder or granules.
ガラス繊維としては、一般にその繊維長が約５００μｍ
以上のものが用いられる。Glass fibers generally have a fiber length of about 500 μm.
The above are used.

化するようになる。These oleoresins and glass fibers contain about 10% of the oleoresin in the composition composed of these and the acetal resin.
-30% by weight, preferably about 15-25% by weight2, and glass fibers in a proportion of about 2-10% by weight2, preferably about 3% by weight2.
Each is used in a proportion of ~7% by weight. If the proportion of glass fiber used is less than this, the desired effect of the present invention cannot be obtained, while if it is used in a proportion greater than this, the sliding properties will deteriorate.

うになる。Acetal resin is the stiffest resin, has long fatigue life, good resilience, low moisture sensitivity, good solvent and chemical resistance, and has excellent electrical insulation properties. Therefore, it is effectively used in applications such as bushings, ball seats, gears, etc. In particular, by mixing it with the oleoresin used in the present invention, it is possible to improve the sliding characteristics of molded products. At this time, by using glass fiber in combination, it compensates for the decrease in rigidity of the acetal resin, which has become flexible due to the mixing of the oleoresin, and exhibits excellent sliding characteristics even in a high load range.
