Description
本発明はボレート(ホウ酸エステル)の添加が必要でない新規DOT4ブレーキ液に関する。前記ブレーキ液は

The present invention relates to a novel DOT4 brake fluid that does not require the addition of borates (borate esters). The brake fluid is (a) 10 to 50% by mass of diethylene glycol and / or dipropylene glycol.
And (b) (poly) ethylene glycol monoalkyl ether and / or (poly) propylene glycol monoalkyl ether 50-90% by weight

油圧液および特に自動車用ブレーキ液は化学的および物理的特性に関するきわめて高い要求が課せられる。連邦自動車安全標準規格(FMVSS)No116および自動車エンジン協会により刊行された標準規格SAEJ1704における米国運輸局(US Department of Transportation、DOT)のブレーキ液に関する既存の標準規格および規格により、近代的なブレーキ液は高い平衡還流沸騰点(ERBP)および高い湿潤ERBPを有するべきであり、他方で広い温度範囲内でわずかにのみ変化する粘度を有するべきである。 Hydraulic fluids and especially automotive brake fluids place very high demands on chemical and physical properties. Due to the existing standards and standards for brake fluids of the US Department of Transportation (DOT) in the Federal Motor Vehicle Safety Standard (FMVSS) No. 116 and the standard SAEJ 1704 published by the Automotive Engine Association, modern brake fluids It should have a high equilibrium reflux boiling point (ERBP) and a high wet ERBP, while having a viscosity that varies only slightly within a wide temperature range.
従ってFMVSSNo116によるDOT4ブレーキ液に関して以下に示される規格値を満足することが必要である。
ERBP:230℃以上
湿潤ERBP:155℃以上
−40℃での粘度:1800mm2/s以下。
Therefore, it is necessary to satisfy the standard values shown below for the DOT4 brake fluid according to FMVSS No. 116.
ERBP: 230 ° C. or higher, wet ERBP: 155 ° C. or higher, viscosity at −40 ° C .: 1800 mm 2 / s or lower.
更にブレーキ液に含まれる腐食防止剤添加物により達成できる、ブレーキ液による腐食から金属および非鉄金属を十分に良好に保護するより厳しい要求が存在する。市販されているDOT4ブレーキ液は常にホウ酸エステル、例えばメチルトリグリコールボレートを含有し、この物質は所定の量の浸透する水を加水分解によりブレーキ液から化学的に除去することができる。1つの欠点はホウ酸エステルがそれ自体吸湿性であり、結果としてDOT4ブレーキ液が、特に高い相対湿度の地域、例えば熱帯および亜熱帯の地域できわめて速く多くの水分を吸収し、ホウ酸エステルの捕捉機能にもかかわらずホウ酸エステルを満たしたブレーキ装置の作業能力に不利に作用することがある。 Furthermore, there are more stringent demands for sufficiently good protection of metals and non-ferrous metals from corrosion due to brake fluid, which can be achieved by corrosion inhibitor additives contained in the brake fluid. Commercially available DOT4 brake fluid always contains a borate ester, such as methyl triglycol borate, which can chemically remove a predetermined amount of permeating water from the brake fluid by hydrolysis. One drawback is that borate esters are hygroscopic per se, and as a result DOT4 brake fluid absorbs a lot of water very quickly, especially in high relative humidity areas, such as tropical and subtropical areas, and captures borate esters. Despite its function, it can adversely affect the working capacity of brake equipment filled with borate esters.
米国特許第3625899号は少なくとも1種のホウ酸エステル54.5〜92%、ポリアルキレングリコール20%まで、およびポリグリコールモノアルキルエーテルまたはポリグリコールジアルキルエーテル3〜43%、更に他の添加剤を含有するDOT4ブレーキ液を記載する。 U.S. Pat. No. 3,625,899 contains at least one borate ester 54.5-92%, polyalkylene glycol up to 20%, and polyglycol monoalkyl ether or polyglycol dialkyl ether 3-43%, plus other additives DOT4 brake fluid to be described.
米国特許第3972822号はポリグリコールモノアルキルエーテル40〜65%、ポリグリコール16〜45%、およびホウ酸エステル10〜19%、更に腐食防止剤を含有するDOT4ブレーキ液を記載する。 U.S. Pat. No. 3,972,822 describes a DOT4 brake fluid containing 40-65% polyglycol monoalkyl ether, 16-45% polyglycol, and 10-19% borate ester, and further containing a corrosion inhibitor.
WO00/46325号はメチルトリグリコールボレート、グリコールエーテルおよびグリコールを異なる量で含有し、更に添加剤を含有するDOT4ブレーキ液を記載する。 WO 00/46325 describes a DOT4 brake fluid containing methyl triglycol borate, glycol ether and glycol in different amounts and further containing additives.
WO02/38711号も種々のメチルポリグリコールボレート、ポリグリコールモノアルキルエーテル、および腐食防止剤を含有する相当するDOT4ブレーキ液を開示する。 WO 02/38711 also discloses corresponding DOT4 brake fluids containing various methyl polyglycol borates, polyglycol monoalkyl ethers, and corrosion inhibitors.
ドイツ特許第3627432号はグリコール成分30〜80%およびポリグリコールアルキルエーテル70%までを含有するボレート不含のブレーキ液を記載する。グリコール成分はジエチレングリコールおよび/またはジプロピレングリコール0〜80%、有利に55〜80%質量%を含有する。ポリグリコールアルキルエーテル成分は少なくとも1種のポリグリコールモノアルキルエーテル0〜90質量%、有利に0〜50質量%を含有する。これらの液体は選択された混合比でDOT4規格を満たす。これらの組成物の場合の1つの欠点はERBP値が特に規格の限界をわずかに上回り、更にポリグリコールジアルキルエーテルを使用し、この物質が合成のために費用がかかり、ゴムとシーリング剤の両立しない反応をしばしば生じることである。 German Patent No. 3627432 describes a borate-free brake fluid containing 30-80% glycol component and up to 70% polyglycol alkyl ether. The glycol component contains 0 to 80%, preferably 55 to 80% by weight of diethylene glycol and / or dipropylene glycol. The polyglycol alkyl ether component contains 0 to 90% by weight, preferably 0 to 50% by weight, of at least one polyglycol monoalkyl ether. These liquids meet the DOT4 standard at selected mixing ratios. One drawback with these compositions is that the ERBP value is slightly above the specification limit, in particular, uses polyglycol dialkyl ethers, which are expensive to synthesize and are incompatible with rubber and sealants It often causes a reaction.
更にDOT4規格を満たす低粘性ブレーキ液が必要である。 Furthermore, a low-viscosity brake fluid that satisfies the DOT4 standard is required.
本発明の課題は前記ブレーキ液を提供することである。有利にこのブレーキ液はあまり吸湿性でなく、高い相対湿度の地域で使用できるべきである。特に少ない量のホウ酸エステルを使用することが必要であるか、またはこれらのエステルの使用が完全に必要でないべきである。 An object of the present invention is to provide the brake fluid. Advantageously, this brake fluid is not very hygroscopic and should be usable in areas of high relative humidity. In particular, it should be necessary to use small amounts of boric acid esters or the use of these esters should not be necessary at all.

特に本発明の液体はホウ酸エステルを含まない。 In particular, the liquid of the present invention does not contain a borate ester.
ジエチレングリコールまたはジプロピレングリコールまたは任意の所望の比のジエチレングリコールとジプロピレングリコールの混合物を使用できる。ジエチレングリコールが有利である。 Diethylene glycol or dipropylene glycol or a mixture of diethylene glycol and dipropylene glycol in any desired ratio can be used. Diethylene glycol is preferred.
ジエチレングリコールおよび/またはジプロピレングリコールは新規ブレーキ液に10〜50質量%、有利に20〜40質量%の量で存在する。 Diethylene glycol and / or dipropylene glycol is present in the new brake fluid in an amount of 10 to 50% by weight, preferably 20 to 40% by weight.
本発明のブレーキ液の他の1つの成分は(ポリ)エチレングリコールおよび/または(ポリ)プロピレングリコールのモノアルキルエーテルの1種以上からなり、前記物質は本発明の液体に50〜90質量%、有利に60〜80質量%の量で存在する。 Another component of the brake fluid of the present invention comprises one or more monoalkyl ethers of (poly) ethylene glycol and / or (poly) propylene glycol, and the substance is 50 to 90% by mass in the liquid of the present invention. It is preferably present in an amount of 60 to 80% by weight.
適当な(ポリ)エチレングリコールの例はモノエチレングリコール、ジエチレングリコール、トリエチレングリコール、テトラエチレングリコール、ペンタエチレングリコール、およびヘキサエチレングリコールである。 Examples of suitable (poly) ethylene glycols are monoethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, pentaethylene glycol, and hexaethylene glycol.
適当な(ポリ)プロピレングリコールの例はモノプロピレングリコール、ジプロピレングリコール、トリプロピレングリコール、テトラプロピレングリコール、ペンタプロピレングリコール、およびヘキサプロピレングリコールである。 Examples of suitable (poly) propylene glycols are monopropylene glycol, dipropylene glycol, tripropylene glycol, tetrapropylene glycol, pentapropylene glycol, and hexapropylene glycol.
ジエチレングリコール、トリエチレングリコールおよび/またはテトラエチレングリコールが有利である。 Diethylene glycol, triethylene glycol and / or tetraethylene glycol are preferred.
本発明により使用される(ポリ)エチレングリコールおよび(ポリ)プロピレングリコールのモノアルキルエーテル中のアルキル基は有利に直鎖状または分枝状C1〜C6−アルキル基である。直鎖状または分枝状C1〜C4−アルキル基、例えばメチル、エチル、イソプロピル、n−プロピル、n−ブチル、イソブチル、s−ブチル、またはt−ブチルを使用することがより有利である。 The alkyl groups in the monoalkyl ethers of (poly) ethylene glycol and (poly) propylene glycol used according to the invention are preferably linear or branched C 1 -C 6 -alkyl groups. Linear or branched C 1 -C 4 - alkyl groups such as methyl, ethyl, isopropyl, n- propyl, n- butyl, more advantageous to use isobutyl, s- butyl or t- butyl, .

本発明のブレーキ液は湿潤ERBP値、特にボレート不含ブレーキ液を使用して現在まで達成されたERBP値に近いERBP値を有する。この値は現在ボレート含有液体を使用してのみ達成される値に匹敵する。しかしボレートの不在により、本発明の液体はボレート含有液体よりかなり吸湿性が劣る。これは特に熱帯および亜熱帯の地域で使用する間有利であり、それは一部の水がボレートの添加により結合するにもかかわらず、水がかなり速く吸収されるからである。これはそれぞれの場合にブレーキ液の特性の劣化を生じる。特にこの特性の損失は自動車のブレーキ系統で頻繁に起こり、液体の貯蔵および搬送の間にも起こる。本発明のブレーキ液は前記欠点を有しない。 The brake fluid of the present invention has a wet ERBP value, in particular an ERBP value close to the ERBP value achieved to date using a borate-free brake fluid. This value is comparable to that currently achieved only using a borate-containing liquid. However, due to the absence of borate, the liquids of the present invention are much less hygroscopic than the borate-containing liquids. This is particularly advantageous during use in tropical and subtropical regions, since water is absorbed much faster, even though some water is combined by the addition of borate. This causes a deterioration of the characteristics of the brake fluid in each case. In particular, this loss of properties occurs frequently in automobile brake systems and also during liquid storage and transport. The brake fluid of the present invention does not have the above drawbacks.
本発明のブレーキ液が種々の量のホウ酸エステルを含有してもよいことは確かに該当する。しかしこれにより低い吸湿性という本発明の利点は一般に達成されない。これは特にホウ酸エステルを技術水準による一般的な量で添加する場合である。 It is certainly true that the brake fluid of the present invention may contain various amounts of boric acid ester. However, this does not generally achieve the advantage of the present invention of low hygroscopicity. This is especially the case when boric acid esters are added in the usual amounts according to the state of the art.
更に本発明の液体は特にポリアルキレングリコールジアルキルエーテルを含まない。前記エーテルが種々の量で存在できるにもかかわらず、本発明のブレーキ液の利点、特にゴムとシーリング剤との相溶性は一般に達成されず、これはもちろん存在するポリアルキレングリコールジアルキルエーテルの量に依存する。 Furthermore, the liquids according to the invention do not contain polyalkylene glycol dialkyl ethers in particular. Despite the fact that the ether can be present in various amounts, the advantages of the brake fluids of the present invention, in particular the compatibility between the rubber and the sealing agent, are generally not achieved, which of course depends on the amount of polyalkylene glycol dialkyl ether present. Dependent.
本発明の組成物に任意成分として更にポリグリコールが存在してもよい。エチレンオキシドおよび/またはプロピレンオキシドおよび/またはブチレンオキシドと水またはジオールのかなり高い沸点の反応生成物を有利に使用する。特にエチレンオキシドおよびプロピレンオキシドの混合物と水の反応生成物を使用する。前記ポリグリコール中のアルキレンオキシド単位の数は一般に2〜10,有利に2または3であり、5%までの量で存在する。 Polyglycols may further be present as an optional component in the composition of the present invention. Preference is given to using the rather high boiling point reaction products of ethylene oxide and / or propylene oxide and / or butylene oxide with water or diol. In particular, a reaction product of water with a mixture of ethylene oxide and propylene oxide is used. The number of alkylene oxide units in the polyglycol is generally from 2 to 10, preferably 2 or 3, and is present in an amount of up to 5%.
これらの高沸点ポリグリコールの作用は潤滑剤の作用であり、温度−粘度特性のかなりの改良による。ポリグリコールはしばしば高い温度で低い粘度を有するポリグリコールモノアルキルエーテルに十分な粘度を付与し、十分な潤滑性を保証する。自動車ブレーキ系統の部品においてはゴムまたはエラストマーがきわめて摩耗を少なくして金属上を滑走することが必要であるので、十分な潤滑性が望ましい。 The action of these high boiling polyglycols is that of a lubricant and is due to a significant improvement in temperature-viscosity characteristics. Polyglycols often impart sufficient viscosity to polyglycol monoalkyl ethers having low viscosity at high temperatures to ensure sufficient lubricity. Sufficient lubricity is desirable because parts of automobile brake systems require that rubber or elastomers slide on metal with very little wear.
