The present invention relates to a method for producing a polyamide resin composition with excellent wear properties.
（従来技術）
一般にポリアミド樹脂は金泥に比較して自己潤滑性に優

ガイドレール等の無注油部品として極めて有用である。(Prior art) Generally, polyamide resin has superior self-lubricating properties compared to gold paint, has a low coefficient of friction, and is resistant to r! l Good abrasion resistance, light weight, and low noise during sliding, making it suitable for bearings, both sides, rollers, cams,
Extremely useful as lubrication-free parts such as guide rails.
しかしながら、摺動部品としてみた場合、限界ｐｖ値が
比鮫的小さいため低負荷の用途に限定されているのが現

耗特性は良好であり、高負荷に耐えることを意味する。Note that the limit pv value mentioned here is generally determined by the constant surface pressure (kg/cf) of the bearing material and the circumferential speed V (m/m1n).
) indicates the limit value of the load at which the material will melt or seize. Therefore, the larger the limit pv value is, the better the wear resistance is, meaning that it can withstand high loads.
このため、従来からポリアミド組成物の摩擦摩耗特性を

低下傾向があり、問題点が残されている。(Problems to be Solved by the Present Invention) However, if the above-mentioned lubricant is added, the screw will not penetrate easily during extrusion, and sufficient extrusion molding will not be possible. However, there was a problem with injection moldability, that is, a part of the resin metered during injection flowed back into the cylinder, resulting in short shots in the molded product, and stable extrusion molding and injection molding could not be performed. Alternatively, problems remain, such as problems with the surface properties of the molded product or a tendency for impact resistance to decrease.

向上することを目的としたものであった。Although it is disclosed in Nct No. 3.845,163, it is not intended to provide a polyamide resin composition that has excellent screw penetration properties and injection moldability, as well as excellent friction and wear properties, which is the objective of the present invention. (The purpose was to improve Ji attack resistance.

でてくる。The effective equivalent weight of the amount of microstalline wax (hereinafter abbreviated as M, C, W) added to the polyamide resin composition is 0.
．． 5 to 6.0% by weight is preferable; if it exceeds 6% by weight, the extruded resin may not bite into the screw surface of the extruder or the inside of the cylinder, or the resin may not penetrate into the cylinder during injection molding. There is a strong tendency for water to flow backwards, and mechanical strength is reduced.
また、０．５重量％未満では十分な耐摩擦摩耗特性を発
揮出来ない。Moreover, if it is less than 0.5% by weight, sufficient friction and wear resistance properties cannot be exhibited.
更に、アイオノマーの添加量は５〜２０重量％であり、
２０ｆｆｉ量％を超えると機械的強度の低下、耐摩擦摩
耗特性の低下につながり実用上の問題がある。Furthermore, the amount of ionomer added is 5 to 20% by weight,
If the amount exceeds 20ffi, it leads to a decrease in mechanical strength and a decrease in friction and wear resistance, leading to practical problems.
また、Ｍ、Ｃ，Ｗとアイオノマーの重量比は１／３以下

十分な食い込み性が得られないばかりでなく、成形品は
デラミネイション（相剥離）を起こす傾向が強くなる。Further, the weight ratio of M, C, W and ionomer is preferably 1/3 or less, and if it exceeds 1/3, for example, when melting and kneading the three components in a twin-screw extrusion machine, the weight ratio of M, C, W and ionomer is preferably 1/3 or less. Not only will it not be possible to obtain good biting properties, but the molded product will have a strong tendency to cause delamination (phase separation).

しているものと考えられる。This means that the mff1 ratio of M, C, W/ionomer is 1/3
It is thought that this is because when the ionomer exceeds this value, the ionomer swells to the extent that it separates into two phases from the nylon due to M, C, and W. M
, C, W / ionomer weight ratio of less than 1/3, the ionomer is sufficiently compatible with the nylon, and the ionomer absorbs the microcrystalline wax to form 3
It is thought that this improves the penetration into the screw when the components are melt-kneaded, and also improves the injection moldability of the resulting resin composition.

いる。Below Margin (D) Soyote Shot (Effect) As described above, according to the manufacturing method of the present invention, by mixing a predetermined amount of ionomer into a polyamide resin in which polyamide resin and microstarine wax are uniformly dispersed. This improves the penetration into the screw, allowing melt-kneading without any resistance, and also improves the injection and extrusion properties of the polyamide resin composition obtained.
Furthermore, it has the effect of improving the friction and wear resistance of the molded article.
