本発明は脱脂洗浄溶液に係り、特に、金属材料の表面に
付着し、劣化した油汚れを除去するために使用される脱
脂洗浄溶液に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a degreasing cleaning solution, and more particularly to a degreasing cleaning solution used for removing deteriorated oil stains attached to the surface of metal materials.
従来、油汚れ、たとえば、換気扇の枠部分などに対して
は多種の脱脂洗浄溶液が市販されている。Conventionally, various types of degreasing and cleaning solutions are commercially available for cleaning oil stains, such as the frames of ventilation fans.
それらは主に水系、アルコール系、脂肪族系、芳香族系
、塩化炭化水素系、塩化フッ化炭化水素系、ケトン系、
エーテル系のへ種類に大別される。They are mainly water-based, alcohol-based, aliphatic-based, aromatic-based, chlorinated hydrocarbon-based, chlorinated fluorohydrocarbon-based, ketone-based,
It is broadly divided into etheric types.
しかし、水系のもの、たとえば、水に多量の界面活性剤
を加えたものは洗浄力が弱く、また、酸やアルカリの水
溶液は安全性あるいは安定性に問題があった。However, aqueous solutions, such as those made by adding a large amount of surfactant to water, have weak cleaning power, and acid or alkali aqueous solutions have problems with safety or stability.
次に、アルコール系、脂肪族系、芳香族系のものは洗浄

点があった。Next, even if alcohol-based, aliphatic-based, and aromatic-based products have satisfactory detergency, they have the disadvantage of strong twisting properties.
さらに、ケトン系、エーテル系、塩化炭化水素系のもの
は毒性が強く、塩化フッ化炭化水素系のものは沸点が低
く、蒸発速度が速いとＶ・う欠点があった。Furthermore, ketone, ether, and chlorinated hydrocarbons are highly toxic, and chlorofluorinated hydrocarbons have a low boiling point and a high evaporation rate, resulting in the disadvantage of V. and corrosion.

った。The inventor first developed 1,1.2-) Rechloror 1.2.2-MJ, which has the highest allowable concentration recommended by the Japan Society of Industrial Hygiene, which is 11,000 pp, which is the safest, and is nonflammable.
We considered using fluoroethane (hereinafter referred to as Freon 113) as a degreasing cleaning solution. However, since Flo-Kari 13 had a weak degreasing power and an extremely high evaporation rate, it could not achieve its purpose. Next, the inventor
We considered adding dichloromethane, which has a high allowable concentration of 500 ppm and is highly safe, has strong degreasing power, and is nonflammable. The evaporation rate was also faster than that of Freon 113, so it was not suitable as a degreasing cleaning solution.

。The inventor said that from a safety point of view, the degreasing cleaning solution is Freon 113.
I thought that it had to be made with dichloromethane as the main component, and created an azeotrope with a mixed solution to raise the boiling point, and searched for a substance that has degreasing power, flame retardancy, and high safety. When we conducted experiments on various solutions, we found that 1,1.1-
) dichloromethane was found to satisfy the above conditions. As a result of experimenting with mixing these two types of solutions, it was discovered that the solution had sufficient degreasing and cleaning power, and the present invention was completed.

Put a 1:1 mixed solution of 3 and dichloromethane into a sprayer, apply machine oil to the stainless steel plate,
After a week, there are dried oil stains, oil stains on the frame of a ventilation fan that has been in operation for more than a year, oil stains that have splattered and deteriorated from the sliding surface of the rail of an elevator that has been in operation for more than 5 years, and oil stains that have deteriorated since more than 5 years ago. Grease and other substances adhering to the motor in the installed V-beta machine room were sprayed onto four types of oil stains that had dried and deteriorated.
It was wiped off with a paper towel and evaluated according to the following criteria.
