Description
本発明は、潤滑剤組成物に関する。詳しくは低せん断速度における粘度が低く起動性に優れ、高せん断速度における粘度が高く油膜形成能力に優れ、かつ摺動部表面への密着性が高い潤滑剤組成物に関する。 The present invention relates to a lubricant composition. More specifically, the present invention relates to a lubricant composition having a low viscosity at a low shear rate and excellent startability, a high viscosity at a high shear rate, an excellent oil film forming ability, and a high adhesion to the surface of a sliding part.
従来から、摺動部分には潤滑性を高めるために潤滑油やグリースが使用されている。グリースは、液状の潤滑油に、金属石けんやウレア化合物などの繊維状の増ちょう剤を分散させ、半固体状にした油剤である。半固体状であるため、油漏れしにくく、潤滑システムを簡易化、小型化できるメリットがあり、自動車をはじめ、様々な産業機械の機械要素、特には軸受や歯車などに広く用いられている（非特許文献１）。具体的な主な適用先としては、自動車、鉄道などの輸送機械、コンピュータなどの情報機器、圧延機などの鉄鋼設備、工作機械、搬送システムや建設機械などの産業機械などが挙げられる。
しかし、近年の各種機械システムの高性能化・小型化・軽量化に伴い、機械要素にかかる負荷は増大傾向にあり、従来のグリースでは起動性、耐焼付き性、耐摩耗性、低摩擦性等の点で必ずしも十分ではなく、機械要素の高性能化、小型化及び長寿命化を達成するためには改善の余地がある。より具体的には、低せん断時の粘性抵抗が高いため、起動ロスが大きく、また高せん断時の粘度低下により、油膜切れが生じやすく、摺動部の摩擦摩耗が課題であった。
Conventionally, lubricating oil and grease have been used for the sliding portion in order to improve lubricity. Grease is an oil agent in which a fibrous thickener such as a metal soap or a urea compound is dispersed in a liquid lubricating oil to form a semi-solid. Because it is semi-solid, it has the advantage of preventing oil leakage and simplifying and miniaturizing the lubrication system, and it is widely used in machine elements of various industrial machines including automobiles, especially bearings and gears ( Non-patent document 1). Specific application destinations include transportation equipment such as automobiles and railways, information equipment such as computers, steel equipment such as rolling mills, machine tools, industrial machines such as transport systems and construction machines, and the like.
However, along with recent improvements in performance, size, and weight of various mechanical systems, the load on machine elements is increasing. With conventional grease, start-up, seizure resistance, wear resistance, low friction, etc. However, there is room for improvement in order to achieve high performance, miniaturization, and long life of the machine elements. More specifically, since the viscous resistance at the time of low shear is high, the start-up loss is large, and the oil film is easily cut off due to the decrease in viscosity at the time of high shear, and the frictional wear of the sliding part has been a problem.
本発明は、機械システムの高性能化・小型化・軽量化における従来のグリース潤滑では解決できなかった、起動性、油膜形成能を両立するとともに、摺動部に塗布した潤滑油剤が高速回転時でも飛散しにくい特性を有するものであり、具体的には低せん断速度における粘度が低く起動性に優れ、高せん断速度における粘度が高く油膜形成能力に優れ、かつ摺動部表面への密着性が高い潤滑剤組成物を提供することを課題とするものである。 The present invention achieves both startability and oil film forming ability, which could not be solved by conventional grease lubrication in high performance, miniaturization, and weight reduction of a mechanical system, and the lubricant applied to the sliding portion is at high speed rotation. However, it has the characteristic that it is difficult to scatter, specifically, low viscosity at low shear rate and excellent startability, high viscosity at high shear rate and excellent oil film forming ability, and adhesion to the sliding surface. It is an object of the present invention to provide a high lubricant composition.
