More specifically, the present invention relates to a polyester resin composition that has excellent friction and abrasion properties, impact resistance, heat resistance, and water absorption resistance in addition to the excellent properties that polyester resin inherently has.

広汎な用途に用いられている。(Conventional Wave 8) Thermoplastic polyester resins represented by polybutylene terephthalate and polyethylene tylphthalate have excellent chemical resistance, heat resistance, mechanical properties, electrical properties, dimensional stability, flame resistance, and self-lubricating properties. Gears, cams, bearings,
It is used in a wide range of applications such as power tool parts, connectors, plugs, and fuse cases.
しかしながら、一般にポリエステル樹脂は単独では熱変

を一層改善するために通常ガラス繊維をポリエステル樹
脂に配合することが行なわれている。However, polyester resins generally do not have sufficient thermal deformation temperature, mechanical strength, or impact resistance when used alone, so glass fibers are usually blended into polyester resins in order to further improve these properties.
また、結晶性樹脂特有の自己潤滑性に優れているとは言
え、摺動部品としてみた場合、限界Pv値が比較的小さ
い梅、低負荷の用途に限定されている。Furthermore, although it has excellent self-lubricating properties unique to crystalline resins, when viewed as a sliding component, it has a relatively small limit Pv value and is limited to low-load applications.

n) 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 friction and wear resistance is, meaning that it can withstand high loads.

This was a practical problem because it significantly impaired the

This is a polyester resin composition in which 10 to 100 parts by weight of glass fiber and 1 to 50 parts by weight of ultra-high molecular weight polyethylene are uniformly melted and kneaded to 00 parts by weight, and the resulting resin composition has excellent friction/wear properties and impact resistance.

た樹脂ベレットを得る事が望ましい。The particle size of the ultra-high molecular weight polyethylene powder is approximately 200.
The thickness is not more than μm, preferably not more than 50 μm. Even if attempts are made to obtain injection molded or extrusion molded products from these triblends by direct single screwing, it is difficult to obtain uniform molded products due to poor dispersion of the polyester resin and ultra-high molecular weight polyethylene. Therefore, it is desirable to obtain resin pellets that are uniformly kneaded in advance using a twin-screw extruder, single-screw extruder, etc., and then melted and solidified.

量部を越えると樹脂ベレットの製造が困難となる。In the present invention, 10 to 100 parts by weight of glass fiber is added to 100 parts by weight of the polyester resin, but if it is less than 10 parts by weight, the heat distortion temperature will only improve slightly, and if it exceeds 100 parts by weight, the production of resin pellets will be difficult. becomes difficult.

を越えると機械的強度の低下が大きくなる。Further, in the present invention, the amount of ultra-high molecular weight polyethylene added is 1 to 50 parts by weight, preferably 3 to 30 parts by weight, based on 100 parts by weight of the polyester resin. If it is less than 1 part by weight, the effect on friction and wear properties is slight, and if it exceeds 50 parts by weight, the mechanical strength will be significantly reduced.
本発明の組成物から得られる成形品は融点が136℃と

・摩耗特性、耐衝撃性、耐吸水性が向上する。Although the molded article obtained from the composition of the present invention uses ultra-high molecular weight polytylene with a low melting point of 136°C, the heat distortion temperature is surprisingly improved, and in addition, the friction and wear properties are improved. Improves impact resistance and water absorption resistance.
