本発明は、水、ジエチレングリコールジエチルエーテル及び水溶性溶剤を含んでなる洗浄剤組成物と噴射剤とからなるエアゾール型洗浄剤に関する。 The present invention relates to an aerosol type cleaning agent comprising a cleaning composition comprising water, diethylene glycol diethyl ether and a water-soluble solvent, and a propellant.
さらに詳しくは、自動車、機械、精密機器、印刷、樹脂加工、成型加工等の各種工業分野において扱われる部品及びそれらの製造装置等に付着する加工油類、塗料、インク類、樹脂等の汚れに対する洗浄力に優れ、且つ、静電気による着火の危険性のないエアゾール型洗浄剤に関する。 More specifically, it is used to deal with dirt such as processing oils, paints, inks, resins, etc. adhering to parts handled in various industrial fields such as automobiles, machines, precision equipment, printing, resin processing, molding processing, etc. The present invention relates to an aerosol-type cleaning agent that has excellent detergency and does not ignite due to static electricity.
自動車、機械、精密機器、印刷、樹脂加工、成型加工等の各種工業分野において扱われる部品及びそれらの製造装置等には、加工油類、塗料、インク類、樹脂等の汚れが付着する。これらの汚れを除去するための洗浄剤として、洗浄対象物に付着した汚れに対して洗浄剤を直接塗布し、拭きとることにより汚れを除去するエアゾール型洗浄剤が使用されている。 Dirt such as processing oils, paints, inks, resins, and the like adheres to parts handled in various industrial fields such as automobiles, machines, precision equipment, printing, resin processing, molding processing, and their manufacturing apparatuses. As a cleaning agent for removing these stains, an aerosol-type cleaning agent is used in which the cleaning agent is directly applied to the stains attached to the object to be cleaned and wiped to remove the stains.
このエアゾール型洗浄剤としては、ハロゲン系溶剤、炭化水素系溶剤、グリコールエーテル系溶剤、水系洗浄剤、準水系洗浄剤等を洗浄剤組成物とし、液化石油ガス、ジメチルエーテル、フッ化炭化水素等の液化ガスや、窒素ガス、炭酸ガス、亜酸化窒素ガス等の圧縮ガスを噴射剤としたものがあり、様々な状況下で使用されている。 As this aerosol type cleaning agent, a halogen-based solvent, a hydrocarbon-based solvent, a glycol ether-based solvent, an aqueous cleaning agent, a semi-aqueous cleaning agent, etc. are used as a cleaning composition, and liquefied petroleum gas, dimethyl ether, fluorinated hydrocarbon, etc. There are liquefied gas, compressed gas such as nitrogen gas, carbon dioxide gas, and nitrous oxide gas as propellants, which are used in various situations.
しかし、これらのエアゾール型洗浄剤は、毒性、引火性や洗浄力において、満足できるものがない。具体的には、塩素系溶剤を洗浄剤組成物としたエアゾール型洗浄剤は、人体や環境に対する有害性が高く、多くの法規制等を受け、取扱いが難しい問題がある。 However, these aerosol type cleaning agents are not satisfactory in terms of toxicity, flammability and cleaning power. Specifically, aerosol-type cleaning agents containing a chlorinated solvent as a cleaning composition are highly harmful to the human body and the environment, and have a problem that they are difficult to handle due to many laws and regulations.
一般に、エアゾール型洗浄剤が使用される作業環境において、発生する静電気の放電エネルギーは、概ね３０ｍＪ以下と考えられるが、炭化水素系溶剤やグリコールエーテル系溶剤を洗浄剤組成物としたエアゾール型洗浄剤は、引火性を有するため、噴霧した洗浄剤のミストが静電気の放電エネルギーにより着火する危険性が高い（例えば、特許文献１〜３参照）。 In general, the electrostatic discharge energy generated in a working environment in which an aerosol type cleaning agent is used is considered to be approximately 30 mJ or less. However, an aerosol type cleaning agent using a hydrocarbon solvent or a glycol ether solvent as a cleaning composition. Has flammability, and therefore there is a high risk that the sprayed cleaning agent mist is ignited by electrostatic discharge energy (see, for example, Patent Documents 1 to 3).
また、水系洗浄剤や準水系洗浄剤を洗浄組成物としたエアゾール型洗浄剤は、引火性はないが、汚れの除去能力が不十分である。 Moreover, an aerosol type cleaning agent using a water-based cleaning agent or a semi-aqueous cleaning agent as a cleaning composition is not flammable, but has an insufficient ability to remove dirt.
本発明の目的は、加工油類、塗料、インク類、樹脂等の汚れに対して洗浄性が高く、有害性が低く、噴射した洗浄剤が４０℃以下で相分離することなく安定であり、且つ、静電気による着火の危険性がないエアゾール型洗浄剤を提供することである。 The object of the present invention is high in cleaning properties against stains such as processing oils, paints, inks, resins, etc., low in harmfulness, and the sprayed cleaning agent is stable without phase separation at 40 ° C. or less, And it is providing the aerosol type cleaning agent which does not have the danger of ignition by static electricity.
本発明者らは、前述の課題を解決すべく種々の検討を重ねた結果、本発明の洗浄剤は、引火性を消失させるために水を配合しても加工油類、塗料、インク等に対して溶解性の低下が少なく、非引火性の溶液となる水分濃度においても部品等の洗浄に必要な加工油類、塗料、インク等の溶解性を保持できることを見出した。 As a result of various studies to solve the above-mentioned problems, the present inventors have found that the cleaning agent of the present invention can be applied to processing oils, paints, inks, etc. even if water is added to eliminate flammability. On the other hand, it has been found that the solubility of processing oils, paints, inks and the like necessary for cleaning parts and the like can be maintained even at a moisture concentration that results in a non-flammable solution with little decrease in solubility.
さらに、この洗浄剤と、噴射剤として圧縮ガスを用いたエアゾール型洗浄剤は、加工油類、塗料、インク類、樹脂等の汚れに対して洗浄性が高く、且つ、静電気による着火の危険性がないことを見出し、本発明を完成するに至ったものである。 Furthermore, this cleaning agent and aerosol-type cleaning agent that uses compressed gas as a propellant are highly cleanable against dirt such as processing oils, paints, inks, resins, etc., and there is a risk of ignition due to static electricity. As a result, the inventors have found that there is no problem and have completed the present invention.
すなわち、本発明のエアゾール型洗浄剤は、水、ジエチレングリコールジエチルエーテル及び水溶性溶剤を含み、曇点が４０℃以上１００℃未満であることを特徴とする非引火性の洗浄剤組成物と噴射剤とからなるエアゾール型洗浄剤である。 That is, the aerosol-type cleaning agent of the present invention contains water, diethylene glycol diethyl ether, and a water-soluble solvent, and has a cloud point of 40 ° C. or higher and lower than 100 ° C., and a non-flammable cleaning composition and a propellant Is an aerosol type cleaning agent consisting of
以下、本発明についてさらに詳細に説明する。 Hereinafter, the present invention will be described in more detail.
本発明に用いる洗浄剤組成物における水は、洗浄剤組成物の引火点を消失させる作用を有するものであれば特に限定はないが、不純物が少なく、部品や製造装置への影響や洗浄後の仕上がり品質等への影響が少ないもの、例えば、蒸留水やイオン交換水等が好ましく使用できる。 Water in the cleaning composition used in the present invention is not particularly limited as long as it has an action of eliminating the flash point of the cleaning composition. However, there are few impurities, the influence on parts and manufacturing equipment, and after cleaning. Those having little influence on the finished quality, such as distilled water and ion exchange water, can be preferably used.
ここで、非引火性とは、クリーブランド開放式引火点測定法（ＪＩＳ Ｋ ２２６５）で引火が認められないと判断されるものである。 Here, the non-flammability is determined that no flammability is recognized by the Cleveland open-type flash point measurement method (JIS K 2265).
本発明に用いる洗浄剤組成物におけるジエチレングリコールジエチルエーテルは、有害性が低く、乾燥性に優れた溶剤である。これに水を加えると室温においては溶解して均一な溶液となり、加熱すると水が相分離し、水の配合量により概ね３０℃未満に曇点を示す。さらに水溶性溶剤を加えると、曇点が上昇するとともに油分の溶解性が増し、良好な洗浄性を示す。なお、水溶性溶剤の添加量が多く曇点が１００℃以上となる場合は、油分の溶解性が不十分となり、洗浄性も悪化する。また、ジエチレングリコールジエチルエーテルを含まない溶剤は、水を加えて引火点を消失させた場合に、洗浄性、洗浄ムラなどの問題がある。 Diethylene glycol diethyl ether in the cleaning composition used in the present invention is a solvent having low toxicity and excellent drying properties. When water is added to this, it dissolves at room temperature to form a uniform solution, and when heated, the water undergoes phase separation and shows a cloud point below approximately 30 ° C. depending on the amount of water added. When a water-soluble solvent is further added, the cloud point is increased and the solubility of the oil is increased, thereby showing good detergency. In addition, when the addition amount of a water-soluble solvent is large and a cloud point becomes 100 degreeC or more, the solubility of an oil component becomes inadequate and detergency also deteriorates. Moreover, the solvent which does not contain diethylene glycol diethyl ether has problems such as cleaning properties and cleaning unevenness when water is added to eliminate the flash point.
本発明に用いる洗浄剤組成物における水溶性溶剤は、ジエチレングリコールジエチルエーテルよりも水溶性が高いものであれば特に制限はなく、概ね３０℃以上でも水と相溶する水溶性溶剤である。配合比によっては、乾燥性等の悪化を招くため、沸点が２１０℃以下であるものが好ましく、例えば、エチレングリコールモノメチルエーテル、エチレングリコールモノエチルエーテル、エチレングリコールモノプロピルエーテル、エチレングリコールモノブチルエーテル、ジエチレングリコールモノメチルエーテル、ジエチレングリコールモノエチルエーテル、ジエチレングリコールモノプロピルエーテル、プロピレングリコールモノメチルエーテル、プロピレングリコールモノエチルエーテル、プロピレングリコールモノプロピルエーテル、ジプロピレングリコールモノメチルエーテル、ジプロピレングリコールモノエチルエーテル等のグリコールエーテル類；エチレングリコール、ジエチレングリコール、プロピレングリコール、ヘキシレングリコール、イソプレングリコール等のグリコール類；３−メトキシ−１−ブタノール、３−メチル−３−メトキシ−１−ブタノール等のメトキシブタノール類；乳酸メチル、乳酸エチル等の乳酸エステル類；テトラヒドロフルフリルアルコール、フルフリルアルコール等の環状エーテルアルコール類；ガンマブチルラクトン等を例示できる。これらは、１種または２種以上を混合して使用することができる。 The water-soluble solvent in the cleaning composition used in the present invention is not particularly limited as long as it has higher water solubility than diethylene glycol diethyl ether, and is a water-soluble solvent that is compatible with water even at about 30 ° C. or higher. Depending on the blending ratio, it may lead to deterioration of dryness and the like, and therefore, those having a boiling point of 210 ° C. or less are preferable. For example, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, diethylene glycol Glycol ethers such as monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monopropyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monopropyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether; ethylene glycol , Diethylene glycol, propylene glycol, hex Glycols such as lenglycol and isoprene glycol; methoxybutanols such as 3-methoxy-1-butanol and 3-methyl-3-methoxy-1-butanol; lactic esters such as methyl lactate and ethyl lactate; tetrahydrofurfuryl alcohol And cyclic ether alcohols such as furfuryl alcohol; gamma butyl lactone and the like. These may be used alone or in combination of two or more.
上記水溶性溶剤の中でも特に、沸点が１７０℃以上、２１０℃以下のプロピレングリコール、ジエチレングリコールモノエチルエーテル、ジプロピレングリコールモノメチルエーテル、３−メチル−３−メトキシ−１−ブタノール、ジエチレングリコールメチルエチルエーテル等は、ジエチレングリコールジエチルエーテルとの組成変化が少ないことから好ましく、特に好ましくは、引火点がジエチレングリコールジエチルエーテルより高いプロピレングリコール、ジエチレングリコールモノエチルエーテル、ジプロピレングリコールモノメチルエーテルである。 Among the above water-soluble solvents, propylene glycol having a boiling point of 170 ° C. or higher and 210 ° C. or lower, diethylene glycol monoethyl ether, dipropylene glycol monomethyl ether, 3-methyl-3-methoxy-1-butanol, diethylene glycol methyl ethyl ether, etc. And propylene glycol, diethylene glycol monoethyl ether, and dipropylene glycol monomethyl ether, which have a flash point higher than that of diethylene glycol diethyl ether.
本発明に用いる洗浄剤組成物は、曇点が４０℃以上１００℃未満であり、加工油の溶解性がより高くなることから、特に好ましくは、５０℃以上、９０℃以下である。 The cleaning composition used in the present invention has a cloud point of 40 ° C. or higher and lower than 100 ° C., and the solubility of the processing oil becomes higher.
なお、本発明における曇点とは、透明であった溶液が温度の変化により曇りを生ずる温度をいい、非イオン活性剤水溶液で生じる現象と同様に、溶液の温度を上昇させた際に、溶剤を主とする相と水を主とする相に分離し、透明の溶液が濁りを生じ始める温度をいう。 The cloud point in the present invention refers to a temperature at which a transparent solution becomes cloudy due to a change in temperature. Similar to the phenomenon that occurs in a nonionic active agent aqueous solution, when the temperature of the solution is increased, the solvent Is a temperature at which a clear solution starts to become turbid.
本発明に用いる洗浄剤組成物の水、ジエチレングリコールジエチルエーテル及び水溶性溶剤は、すべての成分を配合することによって初めて目的の洗浄剤組成物として優れた効果を発揮し、特に加工油等の油分、塗料、インク等を含む汚れの洗浄用に好適な組成物となる。すなわち、水とジエチレングリコールジエチルエーテル、或いは水と水溶性溶剤だけを配合して非引火性とした組成物は、加工油の溶解性が低く、十分な洗浄性が得られない。また、ジエチレングリコールジエチルエーテルと水溶性溶剤だけを配合した組成物は、引火性の溶液となる。 The water, diethylene glycol diethyl ether and water-soluble solvent of the cleaning composition used in the present invention exert an excellent effect as a target cleaning composition only by blending all the components, particularly oil components such as processing oil, The composition is suitable for cleaning dirt including paints and inks. That is, a composition made non-flammable by blending only water and diethylene glycol diethyl ether or water and a water-soluble solvent has low solubility of processing oil and does not provide sufficient detergency. Moreover, the composition which mix | blended only diethylene glycol diethyl ether and the water-soluble solvent turns into a flammable solution.
