Description
本発明は、エアゾールで内容物を噴出させる噴射用ガスや、除塵ガスとして噴出させる除塵ブロワー用噴射ガスに用いるプロペラントガスに関する。 The present invention relates to a propellant gas used for an injection gas for ejecting contents with an aerosol and an ejection gas for a dust blower to be ejected as a dust removal gas.
従来、エアゾールや除塵ブロワーに用いられるプロペラントガスとしては、フロンガス等の不燃性液化ガス(ＨＦＣ１３４ａ)が使用されていたが、近年では、オゾン層破壊・地球温暖化係数が小さいＨＦＣ１５２ａなどの代替フロンが使用されている。
しかしながら、このＨＦＣ１５２ａであっても、フロンよもオゾン層破壊・地球温暖化係数は小さいものの、ゼロではないので、地球環境によりやさしいプロペラントガスが求められている。 However, even with this HFC152a, although the ozone layer depletion / global warming potential is smaller than that of Freon, it is not zero. Therefore, a propellant gas that is more friendly to the global environment is required.
また、ＨＦＣ１５２ａは可燃性液化ガスであるため、火気に対する安全性が低く、高温の除塵対象物に向けて噴射したり、密閉空間に多量に噴射すると爆発性が高くなるという問題も内包していた。 In addition, since HFC152a is a flammable liquefied gas, it has low safety against fire and has a problem of high explosiveness when it is injected toward a high temperature dust removal object or in a large amount in a sealed space. .
本発明は、このような点に着目してなされたもので、より地球温暖化係数が低減された、不燃性のプロペラントガスを提供することを目的とする。 The present invention has been made paying attention to such a point, and an object thereof is to provide a nonflammable propellant gas having a further reduced global warming potential.
上述の目的を達成するために本発明は、噴射ボタンを備えるスプレー缶に充填されるプロペラントガスであって、トリフルオロヨードメタンガス(ＣＦ３Ｉ)とＨＦＣ１５２ａで知られる１,１−ジフルオロエタンガス(Ｃ２Ｈ４Ｆ２)との２成分からなる混合ガスで構成され、混合ガス中のトリフルオロヨードメタンガス(ＣＦ ３ Ｉ)の重量比率が、６６〜７０重量％、残り１,１−ジフルオロエタンガス(Ｃ ２ Ｈ ４ Ｆ ２ )であることを特徴としている。
In order to achieve the above-mentioned object, the present invention is a propellant gas filled in a spray can equipped with an injection button, which is trifluoroiodomethane gas (CF 3 I) and 1,1-difluoroethane gas known as HFC152a ( consists of a mixed gas consisting of two components with C 2 H 4 F 2), the weight ratio of trifluoroacetic iodo methane in the mixed gas (CF 3 I) is 66-70 wt%, the remainder 1,1-difluoroethane gas It is characterized by being (C 2 H 4 F 2 ).
トリフルオロヨードメタンガス(ＣＦ３Ｉ)は、沸点が−２２.７℃の無色の気体で、１個の炭素原子と３個のフッ素原子と１個のヨウ素原子とからなり、分子構造中に塩素を含まないことから、オゾン破壊能力が殆どないとされている。また、トリフルオロヨードメタンガス(ＣＦ３Ｉ)のＧＷＰ(地球温暖化係数)も殆どゼロとされており、ＨＦＣ１５２ａとの混合ガス中でのトリフルオロヨードメタンガス(ＣＦ３Ｉ)の混合量を増やすにつれて、混合ガスで構成されているプロペラントガスのＧＷＰ(地球温暖化係数)を低減させることが可能となる。 Trifluoroiodomethane gas (CF 3 I) is a colorless gas with a boiling point of −22.7 ° C., which consists of one carbon atom, three fluorine atoms, and one iodine atom, and contains chlorine in its molecular structure. It is said that it has almost no ozone depletion ability. Also, the GWP (global warming potential) of trifluoroiodomethane gas (CF 3 I) is almost zero, and as the mixing amount of trifluoroiodomethane gas (CF 3 I) in the mixed gas with HFC152a is increased. It is possible to reduce the GWP (global warming potential) of the propellant gas composed of the mixed gas.
さらにトリフルオロヨードメタンガス(ＣＦ３Ｉ)は不燃物であることから、ＨＦＣ１５２ａとの混合ガスでの可燃性を低減し、混合量によって、不燃性のプロペラントガスを提供することができることになる。さらに、トリフルオロヨードメタンガスとＨＦＣ１５２ａとは、共沸様混合物となる。 Further, since the trifluoroiodomethane gas (CF 3 I) is an incombustible material, the combustibility with the mixed gas with the HFC 152a can be reduced, and the incombustible propellant gas can be provided depending on the amount of the mixture. Furthermore, trifluoroiodomethane gas and HFC152a become an azeotrope-like mixture.
本発明に係るプロペラントガスは、トリフルオロヨードメタンガス(ＣＦ３Ｉ)を主成分とし、この主成分のトリフルオロヨードメタンガス(ＣＦ３Ｉ)にＨＦＣ１５２ａで知られる１,１−ジフルオロエタンガス(Ｃ２Ｈ４Ｆ２)を混合させた２成分の混合ガスで構成されている。
そして、このプロペラントガスは、噴射ボタンを備えるスプレー缶に充填して使用されるものであって、エアゾールにおいて噴射物を噴出させる噴出剤として、あるいは、除塵ブロワ−として直接対象物に噴射したりするものである。
The propellant gas according to the present invention contains trifluoroiodomethane gas (CF 3 I) as a main component, and 1,1-difluoroethane gas (C 2 ) known as HFC152a is added to the main component trifluoroiodomethane gas (CF 3 I). H 4 F 2 ) is mixed with a two-component mixed gas.
The propellant gas is used by being filled in a spray can equipped with an injection button. The propellant gas can be directly injected onto an object as an expelling agent for injecting an injection in an aerosol or as a dust blower. To do.
表１は、ＨＦＣ１５２ａとＣＦ３Ｉとからなる２成分の各種混合物について、一定温度(３５℃)における飽和蒸気圧を示したものである。 Table 1 shows saturated vapor pressures at a constant temperature (35 ° C.) for various mixtures of two components composed of HFC152a and CF 3 I.
上記表１からわかるように、ＨＦＣ１５２ａとＣＦ３Ｉの混合物は、ＣＦ３Ｉの単体、ＨＦＣ１５２ａの単体よりも蒸気圧が高く、ほぼ共沸混合物様となる。 As can be seen from Table 1, a mixture of HFC152a and CF 3 I, the single CF 3 I, high vapor pressure than single HFC152a, is substantially azeotrope-like.
ＨＦＣ１５２ａとＣＦ３Ｉとからなる２成分の各種混合物について、爆発燃焼試験を行った結果を表２に示す。
この爆発燃焼試験は、中央部に着火用電極を取り付けた覗き窓のついた約２Ｌの円筒形の金属容器の中に、ＨＦＣ１５２ａとＣＦ３Ｉを混合したガスを想定している混合比になるよう導入後、空気を大気圧まで導入して電極からの放電によって、燃焼の有無を確認した。燃焼の有無の判定は、覗き窓からの目視にて行った。
Table 2 shows the results of an explosion combustion test performed on various mixtures of two components composed of HFC152a and CF 3 I.
In this explosion combustion test, the mixture ratio assumes a gas mixture of HFC152a and CF 3 I in a cylindrical metal container of about 2 L with a viewing window with an ignition electrode attached at the center. After the introduction, air was introduced to atmospheric pressure and the presence or absence of combustion was confirmed by discharge from the electrode. Judgment of the presence or absence of combustion was performed by visual observation from a viewing window.
上記表２から、ＨＦＣ１５２ａとＣＦ３Ｉの混合物は、ＨＦＣ１５２ａの混合比率が３３.６以下で燃焼が起こっていないことがわかり、この混合物はＨＦＣ１５２ａの混合比率が３３.６以下では不燃物となる。 From Table 2 above, it can be seen that the mixture of HFC152a and CF 3 I does not burn when the mixing ratio of HFC152a is 33.6 or less, and this mixture becomes noncombustible when the mixing ratio of HFC152a is 33.6 or less. .
ＨＦＣ１５２ａとＣＦ３Ｉとからなる２成分の混合物と、プロペラントガスとして従来から使用されているＬＰＧ、ＨＦＣ１５２ａについて、旧高圧ガス取締法の爆発性試験に準じた試験を行い、爆発の有無を確認した。その結果を表３に示す。この場合、ＨＦＣ１５２ａとＣＦ３Ｉの混合ガスとして、ＣＦ３Ｉ：ＨＦＣ１５２ａが６６：３４のものを使用した。
評価方法は、約５０Ｌの金属製容器の中央部に着火電極、強制攪拌を行うためのファンを左部に取り付けられ、試料用ガスを左上部から一定量導入できる機構を取り付けたものの中に、試料を充填している噴射缶から一定量吹きつけ、電極からの放電によって爆発の有無を確認した。
Performs a test in accordance with the explosiveness test of the old high-pressure gas control method for LPG and HFC152a, which are conventionally used as a propellant gas, and a mixture of two components consisting of HFC152a and CF 3 I, and confirms the presence or absence of an explosion did. The results are shown in Table 3. In this case, a mixed gas of HFC152a and CF 3 I, CF 3 I: HFC152a was used ones 66:34.
In the evaluation method, an ignition electrode and a fan for performing forced stirring are attached to the left part at the center of a metal container of about 50 L, and a mechanism that can introduce a certain amount of sample gas from the upper left part is attached. A fixed amount was sprayed from the spray can filled with the sample, and the presence or absence of an explosion was confirmed by discharge from the electrode.
上記表３から、ＨＦＣ１５２ａとＣＦ３Ｉの混合物においては、爆発が発生しておらず、ＨＦＣ１５２ａとＣＦ３Ｉの混合物は不燃性を示していることがわかる。 From Table 3, in the mixture of HFC152a and CF 3 I, the explosion does not occur, the mixture of HFC152a and CF 3 I it can be seen that indicates a non-flammable.
次に、ＨＦＣ１５２ａとＣＦ３Ｉとからなる２成分の混合物と、プロペラントガスとして従来から使用されているＬＰＧ、ＨＦＣ１５２ａについて、バーナーに対して、４.５cmから５.５cm以下に調整された火炎に対し、各種試料を充填している噴射缶から噴射ボタンを押して、ガス若しくは液化ガスを噴射し、火炎の有無を計測した。その結果を表４に示す。 Next, a flame adjusted to 4.5 to 5.5 cm with respect to the burner for a mixture of two components composed of HFC152a and CF 3 I and LPG and HFC152a conventionally used as a propellant gas On the other hand, the injection button was pushed from the injection can which filled various samples, gas or liquefied gas was injected, and the presence or absence of the flame was measured. The results are shown in Table 4.
上記表４からわかるように、ＨＦＣ１５２ａとＣＦ３Ｉとからなる２成分の混合物は火炎への噴射に対しても不燃性を示している。 As can be seen from Table 4 above, the two-component mixture composed of HFC152a and CF 3 I exhibits nonflammability even when injected into the flame.
上記の結果、本発明にかかるプロペラントガスは、従来使用されているＨＦＣ１３４ａやＨＦＣ１５２ａに比べてＧＷＰ(地球温暖化係数)を小さくすることができるうえ、ＣＦ３Ｉが不燃性物質であることから、不燃性を示し、火気に対する安全性を高めることができる。 As a result of the above, the propellant gas according to the present invention can reduce GWP (global warming potential) as compared with conventionally used HFC134a and HFC152a, and CF 3 I is a nonflammable substance. Can show nonflammability and can improve safety against fire.
そして、この場合、ＨＦＣ１５２ａとＣＦ３Ｉとの混合割合としては、噴射圧力を確保する上で、ＨＦＣ１５２ａの混合割合は、３０重量％以上であることがのぞましく、不燃性確保の観点から、ＣＦ３Ｉの混合割合が６６重量％以上あることが好ましい。このため、本発明にかかるＨＦＣ１５２ａとＣＦ３Ｉとからなる２成分の混合ガスの混合割合としては、トリフルオロヨードメタンガス(ＣＦ３Ｉ)の重量比率が、６６〜７０％の範囲にあることが最も効果的に有効である。 In this case, the mixing ratio of HFC152a and CF 3 I is preferably 30% by weight or more for securing the injection pressure, from the viewpoint of ensuring nonflammability. The mixing ratio of CF 3 I is preferably 66% by weight or more. Therefore, the mixing ratio of the gas mixture of the two components consisting of HFC152a and CF 3 I in accordance with the present invention, the weight ratio of trifluoroacetic iodo methane (CF 3 I) is in the range of 66 to 70% Most effective.
