Definitions
- the present invention relates to a new aerosol cleaning composition for use in cleaning various vehicles, vehicles, transportation vehicles such as automobiles, motorcycles, bicycles, construction machinery, agricultural machinery, airplanes, railway vehicles, ships, etc. ⁇ It is intended to remove oils and fats adhering to the details of various vehicle parts such as bodies, brake parts, suspensions, wheels, etc., and control devices in vehicles / transportation systems.
- Halogen-based solvents are well-known as solvents that do not have a flash point, but chlorine and bromine are limited in production and use due to their harmfulness, and are used in cleaning compositions. Is difficult. Therefore, as a solution to the problem of securing storage volume and safety, water-based products containing carbitol, alcohol, etc. are proposed as products with high flash points using petroleum-based hydrocarbons with a long carbon number and cleaning ingredients. (See Patent Document 1).

・材料および方法
試験例1と同様に、上述した実施例1~3ならびに比較例4のエアゾール組成物をそれぞれ用意する。
本発明の手段のエアゾール組成物である実施例1~実施例3のN2、圧縮空気またはCO2を噴射ガスとして用いるものは、10秒間のスプレー噴射後にエアゾールが直ちに揮発するようなことはなく、エアゾール組成物が棒状の溶液のままで噴出され、5cm、10cm、50cmおよび1m離れた金属板上の直径5cmの狭い範囲を(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液で集中的に濡らすことができるものであることが確認された。CO2を用いる場合、耐圧缶のガス内圧が0.2MPaまでは棒状の溶液のままで噴出させることが出来たが、それを超える内圧にすると、エアゾールが霧状となってしまった。内圧を一定程度以下に留めることで、エアゾールが棒状となり、車両・乗物・輸送機関のブレーキなどの制動装置のような重要部品における樹脂やエラストマーに(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液が接触することを避け、所望の金属部材の油脂などによる汚染箇所のみにピンポイントでエアゾール組成物を噴射させることが可能なものであることが理解される。また、N2または圧縮空気では、内圧を0.2MPaよりも高めてもエアゾール組成物が霧状とならず、2m及び10mといった、より離れた距離の金属板上にまで棒状の溶液のままでエアゾール組成物を到達させ、金属板上の直径5cmの狭い範囲を(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液で集中的に濡らすことができるものであることが確認された。N2または圧縮空気を用いる場合には、より離れた距離の金属板上にまで棒状の溶液のままでエアゾール組成物を到達させることが可能であり、車両・乗物・輸送機関のブレーキなどの制動装置のような重要部品における樹脂やエラストマーに(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液が接触することを避けながらの洗浄における自由度がより高くなるものであることが理解される。
・材料および方法
試験例1と同様に、上述した実施例1~3ならびに比較例4のエアゾール組成物をそれぞれ用意する。
本発明の手段のエアゾール組成物である実施例1~実施例3のN2、圧縮空気またはCO2を噴射ガスとして用いるものは、10秒間の噴射により、金属板上の直径5cmの狭い範囲を(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液で集中的に濡らすことができており、かつ、エアゾールの溶液が乾燥せずに下方に垂れ、グリスまたはオイルがほぼ洗い流せており、○の評価が得られた。また、30秒間噴射することで、金属板上の直径5cmの狭い範囲を(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液で集中的に濡らすことができており、かつ、エアゾールの溶液が乾燥せずに下方に流れ落ち、グリスまたはオイルが溶かされ十分に洗い流されていて、残留が無くなっており、◎の評価が得られた。N2および圧縮空気のものについては、内圧を0.2MPaよりも高めて10mといった、より離れた距離の金属板上のグリスまたはオイルの洗浄性についても確認したが、いずれも、90秒噴射により、金属板上の直径5cmの狭い範囲を(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液で集中的に濡らすことができており、かつ、エアゾールの溶液が乾燥せずに下方に垂れ、グリスまたはオイルがほぼ洗い流せており、○の評価が得られ、さらに180秒噴射することで、金属板上の直径5cmの狭い範囲を(Z)-1-クロロ-3,3,3-トリフルオロプロペン溶液で集中的に濡らすことができており、かつ、エアゾールの溶液が乾燥せずに下方に流れ落ち、グリスまたはオイルが溶かされ十分に洗い流されていて、残留が無くなっており、◎の評価が得られた。エアゾールの噴射状態が棒状となることで、ピンポイントで汚染箇所を狙って洗浄できること、より遠い距離からでもエアゾールの噴射状態が棒状となりピンポイントで汚染箇所を狙って洗浄できることから、装置を分解して接近して洗浄せずとも、離れた距離から洗浄ができ、機械化対応など洗浄工程における汎用性が高まるものであることが理解される。
・材料および方法
本発明の(Z)-1-クロロ-3,3,3-トリフルオロプロペンと噴射ガスを用いるエアゾール組成物ついて、使用する噴射ガスを混合した場合についても評価した。
試験例1と同様しにて、(Z)-1-クロロ-3,3,3-トリフルオロプロペンと噴射ガスとしてN2、CO2とN2、またはCO2とを耐圧缶に充填し、実施例9~16のものを製造した。なお、噴射ガスの充填条件は、以下のように設定した。
実施例9:N2を内圧が0.6MPaとなるまで充填。
実施例10:CO2を内圧0.1MPaとなるよう充填し、次いでN2を内圧が0.6MPaとなるまで充填。
実施例11:CO2を内圧0.2MPaとなるよう充填し、次いでN2を内圧が0.6MPaとなるまで充填。
実施例12:CO2を内圧0.3MPaとなるよう充填し、次いでN2を内圧が0.6MPaとなるまで充填。
実施例13:CO2を内圧0.4MPaとなるよう充填し、次いでN2を内圧が0.6MPaとなるまで充填。
実施例14:CO2を内圧0.5MPaとなるよう充填し、次いでN2を内圧が0.6MPaとなるまで充填。
実施例15:CO2を内圧が0.6MPaとなるまで充填。
また、比較例として、噴射ガスをLPGとし、内圧を0.25MPaに設定した比較例16、(Z)-1-クロロ-3,3,3-トリフルオロプロペンをハンドスプレーに充填した比較例17、(Z)-1-クロロ-3,3,3-トリフルオロプロペンを洗浄瓶に充填した比較例18も用意した。
上記試験を実施した結果を表2に示す。
