Description
本発明は、１，１，１，３，３−ペンタフルオロブタンを含むドライクリーニング用溶剤組成物の改良に関する。 The present invention relates to an improvement in a dry cleaning solvent composition containing 1,1,1,3,3-pentafluorobutane.
地球規模のオゾン層破壊がなく、地球温暖化の影響が小さく、かつ近隣の土壌汚染や地下水汚染を引き起こさず、人体へも無害で、より安価なドライクリーニング用溶剤が求められている。１，１，１，３，３−ペンタフルオロブタンはこの目的に沿った溶剤である。
しかし、１，１，１，３，３−ペンタフルオロブタンは、−２５℃の引火点を持ち、燃焼範囲があるため、条件があえば燃焼する危険がある。
この燃焼性の問題を解決するために、１，１，１，３，３−ペンタフルオロブタンとジクロロペンタフルオロプロパンとを混合したドライクリーニング用溶剤組成物が提案されている（特許文献１参照）。
There is a need for an inexpensive dry cleaning solvent that does not cause global ozone depletion, is less affected by global warming, does not cause nearby soil or groundwater contamination, is harmless to the human body, and is cheaper. 1,1,1,3,3-Pentafluorobutane is a solvent for this purpose.
However, since 1,1,1,3,3-pentafluorobutane has a flash point of −25 ° C. and a combustion range, there is a risk of burning under certain conditions.
In order to solve this problem of combustibility, a solvent composition for dry cleaning in which 1,1,1,3,3-pentafluorobutane and dichloropentafluoropropane are mixed has been proposed (see Patent Document 1). .
このドライクリーニング用溶剤組成物は、不燃化には寄与するが、アクリル樹脂に対する影響が、１，１，１，３，３−ペンタフルオロブタン、ジクロロペンタフルオロプロパンをそれぞれ単独で使用した場合より大きく、アクリル樹脂製ボタンや接着樹脂に影響を与え好ましくない。
また、ジクロロペンタフルオロプロパンはオゾン層を破壊する特定フロンであり、２０１９年に全廃が予定されている物質である。
Further, dichloropentafluoropropane is a specific chlorofluorocarbon that destroys the ozone layer, and is a substance scheduled to be completely abolished in 2019.
本発明は、１，１，１，３，３−ペンタフルオロブタンを使用して、不燃性化することを確保すると共に、アクリル樹脂に対する影響を小さくし、かつオゾン層を破壊する特定フロンではないドライクリーニング用溶剤組成物を提供することを課題とする。 The present invention uses 1,1,1,3,3-pentafluorobutane to ensure nonflammability, reduce the influence on the acrylic resin, and is not a specific chlorofluorocarbon that destroys the ozone layer. It is an object to provide a solvent composition for dry cleaning.
上記課題を解決するために本発明は、１，１，１，３，３−ペンタフルオロブタン４０〜６０重量％と、ハイドロフルオロエーテル６０〜４０重量％とを混合しドライクリーニング溶剤組成物とする。
前記ハイドロフルオロエーテルは、１，１，２，２−テトラフルオロエチル−２，２，２−トリフルオロエチルエーテルであるとよい。
In order to solve the above-mentioned problems, the present invention mixes 1,1,1,3,3-pentafluorobutane 40 to 60% by weight and hydrofluoroether 60 to 40% by weight to obtain a dry cleaning solvent composition. .
The hydrofluoroether may be 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether.
請求項１の発明は、アクリル樹脂に対する影響がほとんどなく、アクリル樹脂製ボタンや被服を接着した樹脂に影響を与えず、各種素材の被服に使用できる。また、オゾン層を破壊しない。ソープを配合しやすく、洗浄能力を向上できる。
請求項２の発明では、ハイドロフルオロエーテルが１，１，２，２−テトラフルオロエチル−２，２，２−トリフルオロエチルエーテルであるので、機械中での分解がなく、乾燥速度が速い。
請求項３の発明は、ソープを配合し、洗浄能力を向上できる。
The invention of claim 1 has almost no effect on the acrylic resin, and does not affect the resin to which the button made of acrylic resin or clothing is adhered, and can be used for clothing of various materials. It does not destroy the ozone layer. Easy to mix soap and improve cleaning ability.
In the invention of claim 2, since the hydrofluoroether is 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether, there is no decomposition in the machine and the drying speed is fast.
The invention of claim 3 can improve the cleaning ability by blending soap.
以下本発明の実施の形態について説明する。 Embodiments of the present invention will be described below.
本発明のドライクリーニング溶剤組成物は、１，１，１，３，３−ペンタフルオロブタンとハイドロフルオロエーテルを混合したものである。１，１，１，３，３−ペンタフルオロブタンが４０〜６０重量％、その残余がハイドロフルオロエーテルであるが、カチオン系や非イオン系界面活性剤からなるソープを配合してもよい。
１，１，１，３，３−ペンタフルオロブタンが６０重量％より多いと、すなわちハイドロフルオロエーテルが４０重量％より少ないと、ドライクリーニング溶剤組成物は、燃焼性があり、また、アクリル樹脂が若干溶解する。
一方、１，１，１，３，３−ペンタフルオロブタンが４０重量％より少ないと、すなわちハイドロフルオロエーテルが６０重量％より多いと、洗浄性の良いソープを溶解できず、洗浄性能が悪い。
The dry cleaning solvent composition of the present invention is a mixture of 1,1,1,3,3-pentafluorobutane and hydrofluoroether. Although 1,1,1,3,3-pentafluorobutane is 40 to 60% by weight and the remainder is hydrofluoroether, a soap composed of a cationic or nonionic surfactant may be blended.
When 1,1,1,3,3-pentafluorobutane is more than 60% by weight, that is, when the hydrofluoroether is less than 40% by weight, the dry cleaning solvent composition is combustible, and the acrylic resin is Dissolve slightly.
On the other hand, when 1,1,1,3,3-pentafluorobutane is less than 40% by weight, that is, when the hydrofluoroether is more than 60% by weight, a soap having a good cleaning property cannot be dissolved and the cleaning performance is poor.
ハイドロフルオロエーテルは、他のものであってもよいが、１，１，２，２−テトラフルオロエチル−２，２，２−トリフルオロエチルエーテルを使用するとよい。
両溶剤とも安定供給可能であること、ドライクリーニング機械中での分解がなく、乾燥速度が速いという利点がある。
The hydrofluoroether may be other, but 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether may be used.
There are advantages that both solvents can be stably supplied, there is no decomposition in a dry cleaning machine, and the drying speed is high.
このドライクリーニング用溶剤組成物は、アクリル樹脂に対する影響がほとんどなく、アクリル樹脂製ボタンや被服を接着した樹脂に影響を与えず、各種素材の被服に使用できる。また、オゾン層を破壊しない。ソープを配合しやすく、洗浄能力を向上できる。 This solvent composition for dry cleaning has almost no influence on the acrylic resin, does not affect the resin made by adhering the button made of acrylic resin and the clothes, and can be used for clothes of various materials. It does not destroy the ozone layer. Easy to mix soap and improve cleaning ability.
