Description
本発明は洗浄剤組成物に関し、より詳細には、２液硬化型樹脂の未硬化樹脂や混合前の樹脂が付着した樹脂吐出装置等の洗浄に主として用いられる２液硬化型樹脂用洗浄剤組成物に関する。 The present invention relates to a cleaning composition, and more specifically, a cleaning composition for a two-part curable resin that is mainly used for cleaning an uncured two-part curable resin or a resin discharge device to which a resin before mixing is attached. Related to things.
従来、樹脂吐出装置の洗浄には、塩化メチレンなどハロゲン化炭化水素類が使用されてきたが、これらはオゾン層を破壊する原因物質として指摘され、その利用が大きく制限されるようになっており、また一部のハロゲン化炭化水素類は人体に対する安全性に懸念がある。そのため、現在では様々な代替品が提案されており、具体的な代替洗浄剤としては、セロソルブ類やカルビトール系溶剤類、石油系炭化水素、Ｎ−メチル−２−ピロリドンなどが検討されている。 Conventionally, halogenated hydrocarbons such as methylene chloride have been used for cleaning resin discharge devices, but these have been pointed out as causative substances that destroy the ozone layer, and their use has been greatly restricted. In addition, some halogenated hydrocarbons are concerned with safety to human bodies. For this reason, various alternatives have been proposed, and cellosolves, carbitol solvents, petroleum hydrocarbons, N-methyl-2-pyrrolidone, etc. are being considered as specific alternative detergents. .
しかし、これらの代替洗浄剤には汚染選択性の大きいものが多く、対象汚染物によって洗浄剤を変える必要がある。また、セロソルブ類やピロリドン系溶剤には人体への安全性が懸念されるものがあり、取扱いに注意を要する。また、分子内に水酸基を持つセロソルブ類やカルビトール類は、ウレタン樹脂のように水酸基と反応するタイプの樹脂に対して硬化阻害を起こす懸念がある。さらに、それらの洗浄剤の中には引火点が低いものも多く、注意が必要である。 However, many of these alternative cleaning agents have high contamination selectivity, and it is necessary to change the cleaning agent depending on the target contaminant. In addition, cellosolves and pyrrolidone-based solvents are feared for safety to the human body, and handling is necessary. In addition, cellosolves and carbitols having a hydroxyl group in the molecule may cause curing inhibition with respect to a resin of a type that reacts with a hydroxyl group such as a urethane resin. In addition, some of these cleaning agents have a low flash point and need attention.
これらの課題を解決するものとして、例えば特許文献１ではグリコールエーテルの酢酸エステル類と炭素数が１０〜１８の不飽和炭化水素を含む樹脂用洗浄剤組成物が提案されているが、未だ洗浄力が不十分である。 As a solution to these problems, for example, Patent Document 1 proposes a cleaning composition for resins containing glycol ether acetates and unsaturated hydrocarbons having 10 to 18 carbon atoms. Is insufficient.
本発明は上記に鑑みてなされたものであり、２液硬化型のウレタン樹脂のみならず、エポキシ樹脂・シリコーン系樹脂などによる汚染に対しても良好な洗浄性を有し、従来の洗浄剤と異なり汚染選択性がほとんどないことを特長とし、吐出樹脂内に一部混入しても硬化阻害の懸念がなく、且つ人体に対して安全で、オゾン層破壊物質に該当せず、比較的高引火点の洗浄剤組成物を提供することを目的とする。 The present invention has been made in view of the above, and has a good cleaning property not only with a two-component curable urethane resin but also with a contamination due to an epoxy resin / silicone resin, It has a feature that there is almost no contamination selectivity, there is no concern about curing inhibition even if it is partially mixed in the discharge resin, it is safe for the human body, it does not correspond to an ozone depleting substance, and it has a relatively high flammability. An object is to provide a point cleaning composition.
本発明者らは、鋭意研究を重ねた結果、分子内に水酸基を有しない各種溶剤の中から特定のグリコールエーテル類および炭化水素を用いることにより、引火点が高く、且つ幅広い汚染物質に適用可能な洗浄剤組成が得られることを見出し、本発明の完成に至った。 As a result of extensive research, the inventors have a high flash point and can be applied to a wide range of pollutants by using specific glycol ethers and hydrocarbons from various solvents that do not have a hydroxyl group in the molecule. The present inventors have found that a simple cleaning composition can be obtained and have completed the present invention.
すなわち、本発明の２液硬化型樹脂用洗浄剤組成物は、上記の課題を解決するために、次の式（１）で表されるグリコールエーテルアセテート（ａ）および式（２）で表されるグリコールエーテルアセテート（ｂ）を含有するものとする。
（式中、Ｒ１は炭素数１〜４のアルキル基を表し、ｎは１＜ｎ＜３の数を表す。）
（式中、Ｒ２は炭素数１〜４のアルキル基を表し、ｍは１＜ｍ＜３の数を表す。） (In the formula, R 2 represents an alkyl group having 1 to 4 carbon atoms, and m represents a number of 1 <m <3.)
上記洗浄剤組成物は、成分（ａ）を２０〜８０重量％、成分（ｂ）を２０〜８０重量％の範囲内で含有することが好ましい。 The cleaning composition preferably contains component (a) in the range of 20 to 80% by weight and component (b) in the range of 20 to 80% by weight.
また、上記洗浄剤組成物は、成分（ｃ）トリデカン及び／又はテトラデカンを３０重量％以下の割合でさらに含有するものとすることもできる。 The cleaning composition may further contain component (c) tridecane and / or tetradecane in a proportion of 30% by weight or less.
本発明の洗浄剤組成物は、２液硬化型のウレタン樹脂・エポキシ樹脂・シリコーン系樹脂などの未硬化樹脂あるいは混合前の各樹脂組成物が付着した、金属部品・ガラス部品あるいは樹脂吐出装置などの洗浄に使用するものとして、従来のものより適用範囲が広く、様々な未硬化樹脂に対して優れた洗浄性を示すものとなる。また、比較的引火点が高いことから、安全性が高く、加温して使用することも可能である。さらに、万一、樹脂組生物の中に混入しても少量であれば硬化阻害を起こしにくいという長所も有する。 The cleaning composition of the present invention is a metal part, glass part, resin discharge device, or the like to which an uncured resin such as a two-component curable urethane resin, epoxy resin, or silicone resin or each resin composition before mixing is attached. As for what is used for this washing | cleaning, the applicable range is wider than the conventional thing, and it shows the outstanding washability with respect to various uncured resin. In addition, since it has a relatively high flash point, it is highly safe and can be used after heating. Furthermore, even if it is mixed in the resin assemblage, it has an advantage that it is difficult to inhibit curing if the amount is small.
本発明に用いられる上記（ａ）成分の好ましい例としては、ジエチレングリコールモノメチルエーテルアセテート、ジエチレングリコールモノエチルエーテルアセテート、ジエチレングリコールモノプロピルエーテルアセテート、ジエチレングリコールモノブチルエーテルアセテートなどが挙げられる。これらの成分は単独で用いてもよく、二種類以上を混合して用いてもよい。上記（ａ）のグリコールエーテルアセテートについて、Ｒ１の炭素数が５以上になると洗浄性が劣る。また、ｎはエチレンオキサイドの平均付加モル数を表し、ｎは１＜ｎ＜３の数であって、実質的に１以下の数及び３以上の数を含まない。ｎが１以下では人体への安全性が懸念され、ｎが３以上であると洗浄性が劣る。 Preferable examples of the component (a) used in the present invention include diethylene glycol monomethyl ether acetate, diethylene glycol monoethyl ether acetate, diethylene glycol monopropyl ether acetate, diethylene glycol monobutyl ether acetate and the like. These components may be used alone or in combination of two or more. For glycol ether acetates of the above (a), the carbon number of R 1 is 5 or more and cleaning is poor. N represents the average number of moles of ethylene oxide added, and n is a number of 1 <n <3, and does not substantially include a number of 1 or less and a number of 3 or more. When n is 1 or less, there is a concern about safety to the human body, and when n is 3 or more, the cleanability is poor.
本発明に用いられる上記（ｂ）成分の好ましい例としては、ジプロピレングリコールモノメチルエーテルアセテート、ジプロピレングリコールモノエチルエーテルアセテート、ジプロピレングリコールモノプロピルエーテルアセテート、ジプロピレングリコールモノブチルエーテルアセテートなどが挙げられる。これらの成分は単独で用いてもよく、二種類以上を混合して用いてもよい。上記（ｂ）のグリコールエーテルアセテートについて、Ｒ２の炭素数が５以上では洗浄性が劣る。また、ｍはプロピレンオキサイドの平均付加モル数を表し、１＜ｍ＜３の数であって、実質的に１以下の数及び３以上の数を含まない。ｍが１以下では引火点が低いため安全性に懸念があり、ｍが３以上であると洗浄性が劣る。 Preferred examples of the component (b) used in the present invention include dipropylene glycol monomethyl ether acetate, dipropylene glycol monoethyl ether acetate, dipropylene glycol monopropyl ether acetate, dipropylene glycol monobutyl ether acetate and the like. These components may be used alone or in combination of two or more. For glycol ether acetates of the above (b), the number of carbon atoms in R 2 cleaning is inferior in 5 above. M represents the average number of moles of propylene oxide added, and 1 <m <3, and substantially does not include a number of 1 or less and a number of 3 or more. If m is 1 or less, the flash point is low, which is a concern for safety, and if m is 3 or more, the cleanability is poor.
本発明では、さらに（ｃ）成分として、トリデカン、テトラデカンを上記（ａ）及び（ｂ）成分と併用することもできる。これらの成分は単独で用いてもよく、二種類を混合して用いてもよい。炭化水素系溶剤は、炭素数１２以下では引火点が低いため安全性に懸念があり、炭素数１５以上では洗浄性が劣ることから、これらトリデカン及びテトラデカンが好適である。 In the present invention, as the component (c), tridecane and tetradecane can be used in combination with the components (a) and (b). These components may be used alone or in combination of two kinds. The hydrocarbon solvent has a low flash point when the number of carbon atoms is 12 or less, and thus there is a concern about safety. When the number of carbon atoms is 15 or more, the detergency is inferior. Therefore, tridecane and tetradecane are preferable.
本発明の洗浄剤組成物は、上記成分（ａ）と（ｂ）、又はさらに成分（ｃ）を配合して混合することにより得られる。配合割合は、組成物全体を１００重量％としたときに、成分（ａ）を２０〜８０重量％、成分（ｂ）を２０〜８０重量％の範囲内で含有することが好ましい。さらに成分（ｃ）を配合するときは、３０重量％以下の割合とする。 The cleaning composition of the present invention is obtained by blending and mixing the above components (a) and (b), or further component (c). The blending ratio is preferably 20 to 80% by weight of component (a) and 20 to 80% by weight of component (b) when the entire composition is 100% by weight. Furthermore, when mix | blending a component (c), it is set as the ratio of 30 weight% or less.
本発明の洗浄剤の使用に際しては、当該洗浄液を常温で使用しても良好な洗浄効果が得られるが、場合によっては８０℃程度まで加温することや、或はブラッシング・超音波などの物理的操作を加えることで、洗浄性のより一層の向上が期待できる。 When the cleaning agent of the present invention is used, a good cleaning effect can be obtained even if the cleaning liquid is used at room temperature. However, in some cases, the cleaning liquid may be heated to about 80 ° C. Further improvement of detergency can be expected by adding a manual operation.
以下、実施例により本発明をさらに具体的に説明するが、本発明は以下の実施例に限定されるものではない。 EXAMPLES Hereinafter, although an Example demonstrates this invention further more concretely, this invention is not limited to a following example.

The dispersion state was confirmed and evaluated according to the following criteria. If the dispersibility of the filler is good, the detergency of the filler is also good. The results are shown in Table 2.
<Filler dispersibility>
○: Good
Δ: Partial precipitation ×: Impossible
３．引火点
クリーブランド開放式引火点測定器を用いて、洗浄剤の引火点を測定した。引火点が９０℃以上のものを○、８０℃以上９０℃未満のものを△、８０℃未満のものを×として、安全性を判定した。その結果を表２に示す。
3. Flash point The flash point of the cleaning agent was measured using a Cleveland open flash point measuring instrument. Safety was judged as ○ when the flash point was 90 ° C. or higher, Δ when 80 ° C. or higher and lower than 90 ° C., and × when 80 ° C. or lower. The results are shown in Table 2.
表２に示されたように、ジエチレングリコールモノアルキルエーテルアセテートやジプロピレングリコールモノアルキルエーテルアセテートを用いた実施例の洗浄剤組成物は比較的引火点が高く、ウレタン樹脂、エポキシ樹脂の双方に対して良好な洗浄性を示す。また、ポリオレフィンに対しては、成分（Ｃ）の炭化水素系溶剤やジエチレングリコールジブチルエーテルアセテートなど、比較的アルキル鎖の長いものを含有する場合に良好な洗浄性を示す傾向がある。 As shown in Table 2, the cleaning compositions of the examples using diethylene glycol monoalkyl ether acetate and dipropylene glycol monoalkyl ether acetate have a relatively high flash point, and both urethane resin and epoxy resin are used. Good cleanability. Polyolefins tend to show good detergency when they contain a relatively long alkyl chain such as the hydrocarbon solvent of component (C) or diethylene glycol dibutyl ether acetate.
フィラー分散性に関しても、末端にＯＨ基をもつグリコールエーテルや炭化水素系溶剤単独に比べ、ジエチレングリコールモノアルキルエーテルアセテートやジエチレングリコールジアルキルエーテルを用いた実施例のものは、いずれも良好であることが分かる。 Regarding the filler dispersibility, it can be seen that the examples using diethylene glycol monoalkyl ether acetate or diethylene glycol dialkyl ether are all better than the glycol ether having an OH group at the terminal or the hydrocarbon solvent alone.
本発明の洗浄剤組成物は、２液硬化型のウレタン樹脂・エポキシ樹脂・シリコン系樹脂などの未硬化樹脂あるいは混合前の各樹脂組成物が付着した、金属部品・ガラス部品あるいは樹脂吐出装置などの洗浄に特に好適に使用できる。 The cleaning composition of the present invention is a metal part, a glass part, a resin discharge device, etc. to which an uncured resin such as a two-component curable urethane resin, an epoxy resin, or a silicon resin, or each resin composition before mixing is attached. It can be particularly preferably used for washing.
