Abstract
Description
本発明は建設機械用作動油、詳細には建設機械における油圧モータ、油圧シリンダ等の油圧アクチュエータを含む油圧機器を作動させるための建設機械の油圧機器用の作動油に関するものである。 The present invention relates to hydraulic fluid for construction machinery, and more particularly to hydraulic fluid for hydraulic machinery in construction machinery for operating hydraulic machinery including hydraulic actuators such as hydraulic motors and hydraulic cylinders in construction machinery.
建設機械では、油圧モータ、油圧シリンダ等の油圧アクチュエータを含む油圧機器が用いられている。このような建設機械では、エンジンにより油圧ポンプを駆動して加圧された作動油を油圧モータ、油圧シリンダ等の油圧アクチュエータその他の油圧機器に送り、これらの機器を作動させている。このような油圧アクチュエータを含む油圧機器においては、エンジンにより駆動される油圧ポンプから、油圧モータ、油圧シリンダ等の油圧アクチュエータに至る経路に、パイロット弁、制御弁、リリース弁、ブレーキ等の油圧機器を配置して油圧回路が構成されている。 In construction machines, hydraulic equipment including hydraulic actuators such as hydraulic motors and hydraulic cylinders is used. In such a construction machine, hydraulic oil driven by an engine is driven and hydraulic oil pressurized is sent to a hydraulic actuator such as a hydraulic motor and a hydraulic cylinder, and other hydraulic equipment to operate these equipment. In such a hydraulic device including a hydraulic actuator, a hydraulic device such as a pilot valve, a control valve, a release valve, and a brake is provided on a path from a hydraulic pump driven by the engine to a hydraulic actuator such as a hydraulic motor and a hydraulic cylinder. The hydraulic circuit is configured by arranging.
このような油圧アクチュエータを含む油圧機器においては、エンジンまたは駆動部からの伝熱、油圧機器または管路等において加圧、摩擦、配管抵抗等によって発生する熱などにより、高温、例えば60〜80℃前後の高温において操作されており、この温度領域において効率的な操作ができる作動油が求められている。地球環境保護の観点から油圧装置の省エネルギー化、高効率化は重要な課題であり、作動油の処方技術による省エネルギー化の研究開発は多く行われており、作動油の低粘度化を図り、また油性剤を配合して低摩擦化を図っている。しかし建設機械に使用する作動油を低粘度化すると、油圧ポンプおよび制御弁等における内部リークが増大し、省エネルギー化には貢献しない。 In a hydraulic device including such a hydraulic actuator, a high temperature, for example, 60 to 80 ° C., due to heat transfer from an engine or a drive unit, heat generated by pressurization, friction, piping resistance, or the like in a hydraulic device or a pipe line or the like. There is a need for hydraulic oil that is operated at high temperatures before and after, and that can be operated efficiently in this temperature range. From the viewpoint of protecting the global environment, energy saving and high efficiency of hydraulic systems are important issues, and much research and development has been conducted on energy saving using hydraulic oil prescription technology. An oil-based agent is blended to reduce friction. However, reducing the viscosity of hydraulic oil used in construction machinery increases internal leaks in hydraulic pumps and control valves and does not contribute to energy saving.
また油性剤の配合により低摩擦化すると、建設機械においては湿式ディスクを利用するブレーキにおける摩擦係数が低下することにより、旋回部分や走行あるいは駐車用のブレーキ能が低下して操作性が悪化する。例えば油圧ショベルでは、旋回部分のほか、走行用あるいは駐車用のブレーキを有するが、ハイドロスタティックトランスミッション(HST)搭載ブルドーザのように旋回部分を含まないものでも、走行用あるいは駐車用のブレーキを有する。このように建設機械では、スイングモータ等による旋回部分や、走行用あるいは駐車用のブレーキとして、湿式ディスクを利用するブレーキが用いられている。このような湿式ディスクを利用するブレーキでは、作動油により潤滑性を持たせているが、作動油の摩擦係数が低下すると、旋回ブレーキ能や、走行あるいは駐車ブレーキ能が悪化し、旋回動作が止まらない、あるいは坂道で滑り落ちるなどの重大事故につながる可能性もある。 Further, when the friction is reduced by blending an oily agent, the friction coefficient of a brake using a wet disk is reduced in a construction machine, so that a turning portion, a braking ability for traveling or parking is reduced, and operability is deteriorated. For example, a hydraulic excavator has a running or parking brake in addition to a turning portion, but even a hydrostatic transmission (HST) -equipped bulldozer does not include a turning portion and has a running or parking brake. Thus, in construction machines, a brake using a wet disk is used as a turning part by a swing motor or the like, or a brake for traveling or parking. Brakes using such wet discs are lubricated with hydraulic oil, but if the friction coefficient of the hydraulic oil decreases, the turning brake performance and running or parking brake performance deteriorate, and the turning operation stops. There is a possibility that it may lead to a serious accident such as not sliding or sliding down a slope.
また建設機械では、夜間等の停止時には低温になり、寒冷時あるいは寒冷地では、例えばマイナス30〜マイナス20℃程度の低温度領域で始動するため、低温において低い粘度を有することが要求される。従ってこのような油圧機器用の作動油としては、マイナス30〜マイナス20℃程度の低温から60〜80℃程度の高温に至る広範な温度範囲において適正な粘度特性を有することが要求される。 In addition, the construction machine has a low temperature when it is stopped at night or the like, and starts in a low temperature range of, for example, about minus 30 to minus 20 ° C. in a cold or cold region. Accordingly, such hydraulic oil for hydraulic equipment is required to have proper viscosity characteristics in a wide temperature range from a low temperature of about minus 30 to minus 20 ° C. to a high temperature of about 60 to 80 ° C.
従来このような油圧機器用の作動油として特許文献1(特開平9−111277号)には、基油に対しアミン系酸化防止剤、フェノール系酸化防止剤、リン酸エステル、ならびに脂肪酸アミドまたは多価アルコールエステルを配合してなる作動油が提案されており、粘度指数向上剤としてポリ(メタ)アクリレートを配合できることが記載されている。特許文献1の作動油は、高圧化に伴う作動油の早期劣化やスラッジ発生などを効果的に防止し、長期間にわたって使用できるとともに、シリンダのビビリ現象を解消して安定した作動特性を示す作動油として提案されている。 Conventionally, as a hydraulic fluid for such hydraulic equipment, Patent Document 1 (Japanese Patent Laid-Open No. 9-111277) discloses amine-based antioxidants, phenol-based antioxidants, phosphate esters, fatty acid amides, A hydraulic oil comprising a monohydric alcohol ester has been proposed, and it is described that poly (meth) acrylate can be blended as a viscosity index improver. The hydraulic oil of Patent Document 1 effectively prevents early deterioration of the hydraulic oil and sludge generation due to high pressure, can be used over a long period of time, and eliminates chattering of the cylinder and exhibits stable operating characteristics. Proposed as an oil.
しかし特許文献1の作動油は、早期劣化やスラッジ発生ならびにシリンダのビビリ現象の解消に着目しているが、低温から60〜80℃程度の高温に至る広範な温度範囲において所定の粘度を有することは考慮されていない。また特許文献1では、シリンダのビビリ現象防止のために添加する脂肪酸アミド等の油性剤が摩擦係数を低下させ、湿式クラッチを利用するブレーキ性能に対する十分な対応がなされていない。特許文献1においても、粘度指数向上剤としてポリ(メタ)アクリレートを配合できることが記載されているが、具体的な記載はない。 However, the hydraulic fluid of Patent Document 1 focuses on early deterioration, sludge generation, and elimination of chattering in the cylinder, but has a predetermined viscosity in a wide temperature range from low temperature to high temperature of about 60 to 80 ° C. Is not considered. Further, in Patent Document 1, an oily agent such as fatty acid amide added to prevent the chatter phenomenon of the cylinder reduces the friction coefficient, and does not sufficiently cope with brake performance utilizing a wet clutch. Patent Document 1 also describes that poly (meth) acrylate can be blended as a viscosity index improver, but there is no specific description.
特許文献2(特開2007−91768号)には、ドアクローザ用の作動油として、鉱油または炭化水素系合成油からなる炭化水素系基油に、粘度指数向上剤としてポリ(メタ)アクリレート、および潤滑性向上剤として過塩基性カルシウムスルホネートを配合した作動油が提案されている。特許文献2では、脂肪酸、脂肪族アルコール、脂肪酸エステル、油脂などの油性剤を配合されていることが好ましいとされ、実施例においてもこれらの油性剤が配合されている。 Patent Document 2 (Japanese Patent Application Laid-Open No. 2007-91768) discloses a hydrocarbon base oil made of mineral oil or a hydrocarbon-based synthetic oil as a working oil for a door closer, poly (meth) acrylate as a viscosity index improver, and lubrication. Hydraulic oils containing overbased calcium sulfonate as a property improver have been proposed. In Patent Document 2, it is preferred that an oily agent such as a fatty acid, an aliphatic alcohol, a fatty acid ester, or an oil is blended, and these oily agents are also blended in the examples.
しかし特許文献2のドアクローザでは、シリンダ部に設けられたオリフィスを介して作動油を一定速度で通過させることによりドアを円滑に開閉させる機能が求められている。このためドアクローザ用の作動油としては、開閉速度を温度の変化の如何にかかわらず一定に保持させるために、高い粘度指数を有することが要求され、上記の組成とされている。作動油の粘度指数が高いということは、低温でも高温でも一定の動粘度を有することを意味しており、特許文献2では、作動油の粘度指数が250以上であることが好ましく、270以上であることがより好ましいとされている。 However, the door closer of Patent Document 2 is required to have a function of smoothly opening and closing the door by passing hydraulic oil at a constant speed through an orifice provided in the cylinder portion. For this reason, the hydraulic fluid for door closers is required to have a high viscosity index in order to keep the opening / closing speed constant regardless of the temperature change, and has the above composition. The fact that the viscosity index of hydraulic fluid is high means that it has a constant kinematic viscosity at both low and high temperatures. In Patent Document 2, the viscosity index of hydraulic fluid is preferably 250 or more, and preferably 270 or more. It is said that there is more preferable.
特許文献2では、このように高い粘度指数を有する作動油を得るために、粘度指数向上剤としてポリ(メタ)アクリレートを配合しているが、ここで配合されるポリ(メタ)アクリレートの重量平均分子量は、5〜70万とされているが、10〜50万、特に15〜40万であることが好ましいとされており、実施例では25〜55万の高分子量のものが使用されている。しかしこのような高分子量のポリ(メタ)アクリレートを配合すると粘度指数が高くなりすぎ、低温性能と高温における操作性を満足することはできず、また油性剤の配合が必要なため、湿式ディスクを利用するブレーキ性能に対する対応が十分でないなどの問題がある。 In Patent Document 2, in order to obtain a hydraulic oil having such a high viscosity index, poly (meth) acrylate is blended as a viscosity index improver, but the weight average of the poly (meth) acrylate blended here The molecular weight is 5 to 700,000, but it is considered to be preferably 100,000 to 500,000, particularly preferably 1.5 to 400,000, and in the examples, those having a high molecular weight of 25 to 550,000 are used. . However, when such a high molecular weight poly (meth) acrylate is blended, the viscosity index becomes too high to satisfy the low temperature performance and high temperature operability, and it is necessary to blend an oily agent. There are problems such as insufficient response to brake performance.
特許文献3(特開2007−106878号)には、ドアクローザ用の作動油として、40℃の動粘度が2〜20mm2/sでかつ粘度指数が50以上の基油と、ポリ(メタ)アクリレートを含有し、40℃の動粘度が22〜95mm2/s、100℃の動粘度が10〜30mm2/s、流動点が−10℃以下、−20℃のCCS粘度が2500mPa・s以下、引火点が140℃以上の油圧作動油が記載され、上記ポリ(メタ)アクリレートの重量平均分子量が15万〜70万、好ましくは、20万〜50万であり、特許文献2とほぼ同様のことが言える。 Patent Document 3 (Japanese Patent Laid-Open No. 2007-106878) discloses a base oil having a kinematic viscosity at 40 ° C. of 2 to 20 mm 2 / s and a viscosity index of 50 or more as a working oil for a door closer, and poly (meth) acrylate. The kinematic viscosity at 40 ° C. is 22 to 95 mm 2 / s, the kinematic viscosity at 100 ° C. is 10 to 30 mm 2 / s, the pour point is −10 ° C. or less, the CCS viscosity at −20 ° C. is 2500 mPa · s or less, A hydraulic fluid having a flash point of 140 ° C. or higher is described, and the poly (meth) acrylate has a weight average molecular weight of 150,000 to 700,000, preferably 200,000 to 500,000. I can say.
このほか従来技術では、油圧機器用の作動油として、基油に対し他の添加剤とともに、粘度指数向上剤としてポリ(メタ)アクリレートを配合した組成物が使用されているが、粘度指数向上剤を配合するのは、可能な限り粘度指数を向上させて、低温における動粘度と高温における動粘度の差を小さくすることが目的とされている。このために粘度指数向上剤としては、高分子量のポリ(メタ)アクリレートを配合しているが、この場合でも上記特許文献1〜3と同様の問題点がある。
本発明の課題は、上記従来の問題点を解決するため、油性剤の配合を省略しても、高温領域において高い動粘度を有し、これにより内部リークを抑えて効率の良い運転を行うことができ、かつブレーキ特性に優れるとともに、低温領域において低い粘度を有し、低温性能に優れる作動油を提供することである。 The object of the present invention is to solve the above-mentioned conventional problems, and even if the blending of the oily agent is omitted, it has a high kinematic viscosity in a high temperature region, thereby suppressing internal leakage and performing an efficient operation. It is possible to provide a hydraulic oil that has a low viscosity in a low temperature region and is excellent in low temperature performance as well as excellent braking characteristics.

本発明で対象とする建設機械用作動油は、建設機械の油圧機器用の作動油であり、油圧モータ、油圧シリンダ等の油圧アクチュエータを含む油圧機器を作動させるための作動油である。本発明において建設機械とは、建設工事に使用される機械であって、油圧機器を備えたものである。このような建設機械としては、ショベル等の掘削機械;ホイールローダ等の積込み機械;ブルドーザ等の掘削運搬機械;ダンプトラック、不整地運搬車、フォークリフト等の運搬機械、ラフテレーンクレーン等のクレーン、ウインチ類;油圧ブレーカ等の基礎工事機械;アイアンモール等のせん孔、トンネル機械;自走式破砕機等の骨材生産、リサイクル機械;モータグレーダ等の整地、路盤用機械;ロードローラ等の締固め機械、アスファルトフィニッシャ等の舗装機械、除雪車等の道路維持機械などが挙げられる。油圧機器としては、ピストンポンプ等の油圧ポンプ;油圧モータ、油圧シリンダ等の油圧アクチュエータ;圧力制御弁、方向制御弁等の油圧制御弁;湿式ディスクブレーキ等のブレーキ;その他作動油の油圧を利用する機器が挙げられる。 The hydraulic fluid for construction machinery that is the subject of the present invention is hydraulic fluid for hydraulic equipment of construction machinery, and is hydraulic fluid for operating hydraulic equipment including hydraulic actuators such as hydraulic motors and hydraulic cylinders. In the present invention, the construction machine is a machine used for construction work and is provided with hydraulic equipment. Such construction machines include excavators such as excavators; loading machines such as wheel loaders; excavation and transportation machines such as bulldozers; transport machines such as dump trucks, rough terrain vehicles, forklifts, cranes such as rough terrain cranes, winches Kinds; foundation work machines such as hydraulic breakers; drill holes and tunnel machines such as iron malls; aggregate production and recycling machines such as self-propelled crushers; leveling and roadbed machines such as motor graders; compaction machines such as road rollers And paving machines such as asphalt finishers and road maintenance machines such as snow plows. Hydraulic equipment such as piston pumps; hydraulic actuators such as hydraulic motors and hydraulic cylinders; hydraulic control valves such as pressure control valves and directional control valves; brakes such as wet disk brakes; and other hydraulic oil pressure Equipment.
本発明の作動油では、油圧ポンプや制御弁における内部リークを抑えて、省エネルギー化、高効率化を達成するために、運転時における動粘度、すなわち60℃および80℃における動粘度を従来のものより高く設定する。このように運転時における動粘度を高くするために、本発明では、基油として高度精製基油に、ポリ(メタ)アクリレートを粘度指数向上剤として配合する。 In the hydraulic oil of the present invention, the kinematic viscosity at the time of operation, that is, the kinematic viscosity at 60 ° C. and 80 ° C. is achieved in order to achieve energy saving and high efficiency by suppressing internal leakage in the hydraulic pump and the control valve. Set higher. Thus, in order to increase the kinematic viscosity during operation, in the present invention, poly (meth) acrylate is blended as a viscosity index improver in a highly refined base oil as a base oil.
このように高温領域における動粘度を高く設定すると低温時の粘度も高くなり、低温環境における始動性が悪化するので、本発明では、粘度指数が200〜220となるように、特定のポリ(メタ)アクリレートを粘度指数向上剤として配合することにより、マイナス25℃における低温クランキング粘度を低くし、低温作動粘度その他の低温性能を低くすることができる。 When the kinematic viscosity in the high temperature region is set high as described above, the viscosity at the low temperature also increases and the startability in the low temperature environment deteriorates. Therefore, in the present invention, a specific poly (meta) is added so that the viscosity index is 200 to 220. ) By blending acrylate as a viscosity index improver, the low-temperature cranking viscosity at minus 25 ° C. can be lowered, and the low-temperature working viscosity and other low-temperature performance can be lowered.

一方表2に示すように、油性剤を配合した比較例1では、摩擦係数が低く、ブレーキ性能が充分ではない。また動粘度特性が実施例1よりも低い比較例2では、低温操作性が充分であるものの、効率性は標準油と同程度であり改善効果はみられない。また粘度指数が100程度の市販の耐摩耗性作動油では、低温操作性が極めて悪い。
(Discussion):
As shown in Table 1, Example 1 has a high efficiency of 2.0% compared to the standard oil of the reference example in terms of efficiency, and an improvement of 24.6% compared to the standard oil in terms of low temperature operability. It also has a sufficiently high coefficient of friction and excellent braking performance.
On the other hand, as shown in Table 2, in Comparative Example 1 in which an oily agent was blended, the friction coefficient was low and the brake performance was not sufficient. In Comparative Example 2 having a kinematic viscosity characteristic lower than that of Example 1, the low temperature operability is sufficient, but the efficiency is the same as that of the standard oil, and no improvement effect is observed. Further, a commercially available wear-resistant hydraulic oil having a viscosity index of about 100 has extremely poor low temperature operability.
