Description
本発明は油圧作動油組成物、さらに詳しくは、良好な省エネルギー性、熱安定性(耐スラッジ性)、耐摩耗性、耐焼付性(耐スカッフイング性)、水分離性及び摺動部分の摩擦低減性などを有し、油圧機械分野、工作機械分野、産業機械分野などに好適に用いられる油圧作動油組成物に関するものである。 The present invention is a hydraulic fluid composition, more specifically, good energy saving, thermal stability (sludge resistance), wear resistance, seizure resistance (scuffing resistance), water separation, and friction of sliding parts. The present invention relates to a hydraulic fluid composition that has a reducing property and is suitably used in the fields of hydraulic machines, machine tools, industrial machines, and the like.
油圧作動油は、油圧機器や装置などの油圧システムの動力伝達、力の制御、緩衝などの作動に用いられる動力伝達流体であり、摺動部分の潤滑の機能も果たしている。
油圧回路内にはポンプ、制御弁、油圧シリンダーなどに金属−金属や金属−ゴム(樹脂)などの摺動部分が存在する。このような油圧回路に用いられる油圧作動油には、これら摺動部分における耐摩耗性、耐焼付き性、摩擦低減性など摩擦特性が良好であることが求められる。
また、近年油圧作動システムはますます高性能化されており、高速で精密な制御を行うためにスプール弁などにより油圧システムの流量、方向などを制御するケース、更にはサーボバルブを装着するケースが多くなっている。このようなスプール弁やサーボバルブの性能は、油圧作動油中にスラッジが発生すると大幅に低下してしまうため、使用される油圧作動油には、優れた摩擦特性と同時に、スラッジの生成を抑制できる耐スラッジ性に優れる油圧作動油が強く求められるようになっている。
さらに、省エネルギー指向の観点から、摺動部における抵抗を軽減することにより、損失エネルギーの低減や油温上昇の抑制など油圧作動油の高性能化が求められるようになってきた。The hydraulic fluid is a power transmission fluid used for operations such as power transmission, force control, and buffering of a hydraulic system such as a hydraulic device or device, and also functions to lubricate sliding portions.
In the hydraulic circuit, there are sliding parts such as metal-metal and metal-rubber (resin) in pumps, control valves, hydraulic cylinders and the like. The hydraulic fluid used in such a hydraulic circuit is required to have good friction characteristics such as wear resistance, seizure resistance, and friction reduction at these sliding portions.
In recent years, hydraulic operation systems have become more sophisticated, and there are cases in which the flow rate and direction of the hydraulic system are controlled by spool valves, etc., and servo valves are installed in order to perform high-speed and precise control. It is increasing. The performance of such spool valves and servo valves is greatly reduced when sludge is generated in the hydraulic fluid, so the hydraulic fluid used has excellent friction characteristics and suppresses sludge generation. There is a strong demand for hydraulic fluids that have excellent sludge resistance.
Further, from the viewpoint of energy saving, it has been demanded to improve the performance of hydraulic fluid such as reducing energy loss and suppressing oil temperature rise by reducing resistance at the sliding portion.
従来、油圧作動油の摩耗防止剤としてはジチオリン酸亜鉛(ZnDTP)が広く用いられていた。しかし、ZnDTPは、スラッジ発生の原因となり、油圧作動油に配合して長期間使用することができない。また、ZnDTPの使用による摩耗防止効果は、金属表面へのリン酸鉄等の硬い被膜の形成によるものであるが、その被膜の形成により摺動部位の摩擦係数が上昇するため、省エネルギーの観点から好ましいとは言えないこともある。
そこで、ZnDTPを用いない、いわゆる非亜鉛系摩耗防止剤を用いた油圧作動油の検討がなされている。
例えば、ZnDTPの代わりに、芳香族リン酸エステル,亜リン酸エステル及びそのアミン塩、チオホスフェート、β−ジチオホスホリル化プロピオン酸化合物などを摩耗防止剤として配合した油圧作動油が提案されている(例えば、特許文献1、2及び3参照)。
しかしながら、これらの油圧作動油においては、耐スラッジ性(スラッジ抑制性)、耐摩耗性などの摩擦特性を十分に満たしているとは言えず、油圧作動システムの高性能化及び省エネルギー化に対応可能な油圧作動油としては、未だ改善の余地がある。Conventionally, zinc dithiophosphate (ZnDTP) has been widely used as a wear inhibitor for hydraulic fluids. However, ZnDTP causes sludge generation and cannot be used for a long period of time by blending with hydraulic fluid. In addition, the effect of preventing wear due to the use of ZnDTP is due to the formation of a hard coating such as iron phosphate on the metal surface, but the friction coefficient of the sliding part increases due to the formation of the coating, from the viewpoint of energy saving. It may not be preferable.
Therefore, studies have been made on hydraulic fluids that use so-called non-zinc-based anti-wear agents that do not use ZnDTP.
For example, a hydraulic fluid containing an aromatic phosphate ester, phosphite ester and its amine salt, thiophosphate, β-dithiophosphorylated propionic acid compound and the like as an antiwear agent instead of ZnDTP has been proposed ( For example, see Patent Documents 1, 2, and 3.)
However, these hydraulic fluids do not satisfy the friction characteristics such as sludge resistance (sludge suppression) and wear resistance, and can cope with higher performance and energy saving of hydraulic operation system. As a new hydraulic fluid, there is still room for improvement.
また、ZnDTPの代わりに、酸化防止剤と、リン系及び/又は硫黄系化合物と、N−オレイルサルコシンなどを組合せて用いる組成物(例えば、特許文献4参照)、さらには、リン含有カルボン酸化合物と、分散型粘度指数向上剤を組み合わせて含む組成物(例えば、特許文献5参照)が開示されている。
しかし、これらの油圧作動油においても、耐スラッジ性(スラッジ抑制性)、耐摩耗性などの摩擦特性を十分に有するものとは言えない。
したがって、油圧作動油に要求され、省エネルギー性、熱安定性(耐スラッジ性)、耐摩耗性、耐焼付き性(耐スカッフィング性)、さらには水分離性及び摺動部分の摩擦低減性などを、バランスよく満たしているものは見出せないのが現状である。Further, instead of ZnDTP, a composition using a combination of an antioxidant, a phosphorus-based and / or sulfur-based compound, N-oleyl sarcosine, and the like (for example, see Patent Document 4), and further a phosphorus-containing carboxylic acid compound And a composition containing a combination of a dispersion type viscosity index improver (for example, see Patent Document 5).
However, even these hydraulic fluids cannot be said to have sufficient friction properties such as sludge resistance (sludge suppression) and wear resistance.
Therefore, required for hydraulic fluids, energy saving, thermal stability (sludge resistance), wear resistance, seizure resistance (scuffing resistance), water separation and friction reduction of sliding parts, etc. The current situation is that we cannot find anything that is well-balanced.
本発明は、このような状況下で、油圧作動油に対して要求される、省エネルギー性、熱安定性(耐スラッジ性)、耐摩耗性、耐焼付き性(耐スカッフィング性)、水分離性及び摺動部分の摩擦低減性などを、バランスよく満たす油圧作動油組成物を提供することを目的とするものである。 Under such circumstances, the present invention requires energy saving, thermal stability (sludge resistance), wear resistance, seizure resistance (scuffing resistance), water separability, It is an object of the present invention to provide a hydraulic fluid composition that satisfies a good balance of friction reduction properties of sliding portions.
本発明者らは、油圧作動油に対する前記要求性能をバランスよく満たす油圧作動油組成物を開発すべく鋭意研究を重ねた結果、特定の性状を有する基油に、分子量が特定の範囲にあるポリメタクリレート系粘度指数向上剤と、酸アミド化合物と、特定のリン酸エステル系化合物などと、特定の潤滑性向上剤を、それぞれ所定の割合で配合することにより、その目的を達成し得ることを見出した。本発明は、かかる知見に基づいて完成したものである。
すなわち、本発明は、As a result of intensive research to develop a hydraulic fluid composition that satisfies the above required performance for hydraulic fluid in a well-balanced manner, the present inventors have found that a base oil having a specific property has a molecular weight within a specific range.

当該基油の硫黄分が0.03質量%以上であったり、飽和分が90質量%未満であると、酸化安定性が悪く、酸価の上昇やスラッジの生成が生じると共に、非鉄金属に対する腐食性が大きくなり、本発明の効果が充分に発揮されない。硫黄分は、好ましくは0.02質量%以下であり、より好ましくは0.01質量%以下である。また、飽和分は、好ましくは95質量%以上であり、より好ましくは

When the sulfur content of the base oil is 0.03% by mass or more, or the saturated content is less than 90% by mass, the oxidation stability is poor, the acid value increases and sludge is generated, and corrosion on non-ferrous metals occurs. Therefore, the effect of the present invention is not sufficiently exhibited. The sulfur content is preferably 0.02% by mass or less, and more preferably 0.01% by mass or less.
