イドレール等の無注油部品として極めて有用である。
ナイロン６．６６等と比較して平衡吸水率が掻めて小さ
い為、寸法安定性が良く、吸水による機械的物性の低下
が非常に小さいので、その用途は多方面にわたっている
。(Prior art) In general, polyacetal has superior self-lubricating properties compared to metals, has a low coefficient of friction, has good friction resistance and abrasion resistance, is lightweight, and has low noise during driving, so it can be used in bearings, gears, rollers, cams, guide rails, etc. It is extremely useful as an oil-free part such as.
It has a much lower equilibrium water absorption rate than nylon 6.66, etc., so it has good dimensional stability, and the decrease in mechanical properties due to water absorption is very small, so its uses are wide-ranging.
しかしながら摺動部品としてみた場合、限界ＰＶ値が比
較的低いため、低負荷の用途に限定されている。However, when viewed as a sliding component, its limiting PV value is relatively low, so it is limited to low-load applications.
尚、ここでいう限界ｐｖ値とは一般に軸受材料が、ある
一定の面圧Ｐ （ｋｇ／ｃ＋Ｊ）と周速Ｖ （ｍ／−ｉ
ｎ ）以上になると材料が融けたり、焼は付いたりする
負荷の限界値を示す、従って、限界ｐｖ値が大きい程、
耐摩擦、摩耗性は良好であり高負荷に耐えることを意味
する。Note that the limit pv value mentioned here generally means that the bearing material has a certain surface pressure P (kg/c+J) and circumferential speed V (m/-i
n) indicates the limit value of the load at which the material will melt or seize. Therefore, the larger the limit pv value, the more
It has good friction and abrasion resistance, meaning it can withstand high loads.
このため、従来からポリアセタールの摩擦、摩耗特性を

。For this reason, in order to improve the friction and wear characteristics of polyacetal, lubricants such as molybdenum disulfide, graphite, oil, wax, etc. have been added to polyacetal.

行うことができなかった。(Problems to be solved by the invention) However, these molded products have problems such as the surface quality of the product, the penetration of the screw, and the injection moldability (resin metered during injection flows back inside the cylinder, resulting in a short shot of the molded product). However, stable extrusion molding or injection molding could not be performed.

的とする。An object of the present invention is to solve the problems of the above-mentioned conventional techniques and to provide a method for producing a polyacetal resin composition having excellent screw penetration properties, injection moldability, friction resistance, and wear properties.

耐摩擦、摩耗特性において優れている。(Means for Solving the Present Invention) The present invention is characterized by a resin composition obtained by uniformly dispersing 1 to 15 wt% of ultra-high molecular weight polyethylene powder in polyacetal and melt-solidifying it. The mixed resin composition can be obtained into a resin molded body by extrusion molding or injection molding, and is excellent in screw penetration, injection moldability, and friction and wear properties.

からなり、
数平均分子量２０．０００〜１００．０００を有してい
る。The polyacetal used in the present invention is a homopolymer CH20n, a copolymer CH2OCH2CH20n
It has a number average molecular weight of 20.000 to 100.000.
一方、超高分子量ポリエチレンは粘度法による平均分子

、１軸押出機等により予め均一に混練し溶融固化した、
例えば樹脂ベレットを得ることが必要である。The particle size of the ultra-high molecular weight polyethylene powder is approximately 10
~200 μm, and even if an attempt is made to obtain an injection molded or extrusion molded product using a direct single screw method, it is difficult to obtain a uniform molded product due to poor dispersion of polyacetal and ultra-high molecular weight polyethylene. Therefore, for example, the mixture is uniformly kneaded in advance using a twin-screw extruder, a single-screw extruder, etc., and then melted and solidified.
For example, it is necessary to obtain resin pellets.

が薄い。In addition, in the present invention, it is necessary to add 1 to 15% by weight of ultra-high molecular weight polyethylene, but if the amount of ultra-high molecular weight polyethylene added exceeds 15% by weight, the mechanical strength will decrease;
There are problems in practical use, and if it is less than 1 part by weight, the effect of the present invention is weak.

It was found that the resin composition of the present invention had good injection moldability. showed a significant improvement in the critical PV value.
