（産業上の利用分野）
本発明はポリエステル樹脂組成物に関するものであり、
更に詳しくはポリエステル樹脂が本来有する優れた性質
に加えて、摩擦摩耗特性、耐衝撃性、耐熱性に優れた剛
性の高いポリエステル樹脂組成物に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a polyester resin composition,
More specifically, the present invention relates to a highly rigid polyester resin composition that has excellent friction and wear properties, impact resistance, and heat resistance, in addition to the excellent properties inherently possessed by polyester resins.
（従来技術）
ポリブチレンテレフタレート（ＰＢＴ）、ポリエチレン
テレフタレー） （ＰＥＴ）に代表される熱可塑性ポリ
エステル樹脂は耐薬品性、耐熱性、機械的特性、電気的
特性、寸法安定性、耐燃性、自己潤滑性に優れているた
めギア、カム軸受、電動工具部品、コネクター、プラグ
、ヒユーズケース等広汎な用途に用いられている。(Prior art) Thermoplastic polyester resins represented by polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) have chemical resistance, heat resistance, mechanical properties, electrical properties, dimensional stability, flame resistance, and self-possessing properties. Because of its excellent lubricity, it is used in a wide range of applications such as gears, cam bearings, 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
形温度、耐衝撃性等が十分でないため、これらを改善す
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 heat distortion temperature, impact resistance, etc. when used alone, so glass fibers are usually blended with polyester resins in order to improve these properties.
また、該ポリエステル樹脂は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値が比較的小さい為、低負荷の用途に限定されてい
る。Further, although the polyester resin has excellent self-lubricating properties peculiar to crystalline resins, when viewed as a sliding part, the limiting PV value is relatively small, so that 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
一定面圧Ｐ（ｋｇ／Ｃｍ２）と周速Ｖ（ｍ／ｍ１ｎ）以
上になると材料が融けたり焼き付いたりする負荷の限界
値を示す。したがって限界ＰＶ値が大きい程、摩擦摩耗
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 referred to here generally refers to the limit value of the load at which the bearing material melts or seizes when the bearing material exceeds a certain surface pressure P (kg/Cm2) and circumferential speed V (m/m1n). . Therefore, the larger the limit PV value, the better the friction and wear characteristics, which means that the material can withstand high loads.
このため、従来からポリエステル樹脂の摩擦摩耗特性を
改善するためにポリ四フッ化エチレン微粉末、二硫化モ
リブテン、グラファイト等の固体潤滑剤を添加すること
が行なわれている。For this reason, solid lubricants such as polytetrafluoroethylene fine powder, molybdenum disulfide, and graphite have been conventionally added to improve the friction and wear characteristics of polyester resins.
（発明が解決しようとする問題点）
しかしながら、これらの固体潤滑剤はいずれも高価であ
り多量に配合すると価格面からの制約のみならず耐衝撃
強度を著しく損なうという欠点を有していた。そこで我
々は先に安価で性能の良い固体潤滑剤として超高分子量
ポリエチレン微粉末を提案した。（特願昭６２−６７５
６６号）しかし、なおギア、軸受材料としてみた場合、
ガラス繊維を含んでいるため相手材を摩耗させるという
欠点は残されていた。(Problems to be Solved by the Invention) However, all of these solid lubricants are expensive, and when blended in large amounts, they have the disadvantage that not only are they restricted in terms of price, but their impact strength is significantly impaired. Therefore, we first proposed ultra-high molecular weight polyethylene fine powder as an inexpensive and high-performance solid lubricant. (Special application 1986-675
No. 66) However, when viewed as a material for gears and bearings,
Since it contains glass fiber, it still has the drawback of abrading the mating material.
本発明は上記従来技術の問題点を解決し安価で摩擦摩耗

ル樹脂組成物を提供する事を目的とする。The object of the present invention is to solve the problems of the prior art described above and to provide a polyester resin composition that is inexpensive and has excellent friction and wear properties, impact resistance, heat resistance, and mechanical properties.

これらのブレンド物を直接シングルスクリユーにより射
出成形品、押出成形品を得ようとしても、ポリエステル
樹脂と超高分子量ポリエチレンとの分散が悪く均一な成
形品を得ることが困難である。Even if an attempt is made to obtain injection molded or extrusion molded products from these blends 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.
そのため、例えば２軸押出機、１軸押出機等により、予

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, per 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 greatly reduced, which is a practical problem.
