Description of the Related Art Conventionally, as industrial degreasing detergents for metals, ceramics, glass, plastics, etc., water-based detergents represented by alkali detergents and solvent-based detergents represented by 1,1,1-trichloroethane. A cleaning agent is used. Alkali detergents include nonionic surfactants typified by polyoxyethylene alkylphenyl ether, surfactants such as anionic surfactants typified by sodium alkylbenzene sulfonate, sodium carbonate, sodium silicate, sodium borate, Sodium phosphate,
Alkali salts such as sodium hydroxide and potassium hydroxide, chelating agents such as sodium tripolyphosphate, EDTA, NTA and gluconate, benzotriazole, amines,
An alkanolamine, a rust preventive such as sodium nitrite and the like are appropriately mixed. The compounding composition is, for example, Tsuji Recommendation "Precision Cleaning Technology" Engineering Book p117-12.
0, "Precision Cleaning Technology Manual" edited by Tsuji recommended, New Technology Development Center, p50-56, various articles are proposed according to the article to be cleaned, metal, and dirt. However, since the degreasing power and penetrating power are inferior to chlorine-based solvents such as 1,1,1-trichloroethane, practical application fields are cleaning of articles having a simple structure and residual oil content after cleaning. Most of the fields are not so important.

部品の洗浄分野で用いられている。On the other hand, chlorine-based solvents such as 1,1,1-trichloroethane have excellent degreasing and penetrating powers and can be applied to all kinds of degreasing such as cutting oil, drawing oil and press oil.
It is used in the field of cleaning articles with complex structures and precision parts that require high cleanliness.
【０００４】ところが、近年、塩素系溶剤による地下水

浄剤として、従来の水系洗浄剤を適用しつつある。In recent years, however, environmental problems such as groundwater pollution, air pollution, and ozone layer depletion due to chlorine-based solvents have become prominent, and in the industrial world, conventional water-based cleaning is used as a cleaning agent to replace them. The agent is being applied.

ことが難しい。However, the conventional water-based cleaning agents are inferior in degreasing power and penetrating power to chlorine-based solvents, and particularly, there are narrow gaps such as cutting oil, drawing oil and high-viscosity press oil. It is difficult to apply it when it is attached to details or when a very small amount of residual oil on the surface of a component is a problem.

い。In order to increase the degreasing power and penetrating power, it is possible to use a large amount of nonionic surfactant, but there is a problem that it is difficult to make a stable liquid product as a product. In addition, it is possible to increase the pH by increasing the amount of alkali salt in order to enhance the degreasing power, but this also makes it difficult to make a stable liquid product, and it also affects non-ferrous metals and It is not preferable because of safety considerations.

Sodium tert-butylbenzoate has a problem that it is highly toxic to the kidney and liver.

できることを見いだし、本発明を完成するに至った。Means for Solving the Problems As a result of intensive studies, the present inventors have found that the above problems can be solved by combining an alkanolamine, potassium hydroxide, a specific nonionic surfactant, a block polymer and an aliphatic carboxylic acid. They found that they could be solved, and completed the present invention.

する腐食性が出て好ましくない。Examples of the alkanolamine include ethanolamines such as monoethanolamine, diethanolamine, triethanolamine and alkylated products thereof. Potassium hydroxide is used to neutralize the aliphatic carboxylic acid that cannot be completely neutralized with the alkanolamine and adjust the pH. If the total amount of alkanolamine and potassium hydroxide is less than 1% by weight, the detergency will decrease,
If it exceeds 25% by weight, corrosiveness to non-ferrous metals, especially aluminum is exhibited, which is not preferable.

と、安定な液体になりにくくなり好ましくない。Examples of the polyoxyethylene alkylphenyl ether nonionic surfactants include polyoxyethylene octyl phenyl ether and polyoxyethylene nonyl phenyl ether. If the blending amount is less than 1% by weight, the detergency is deteriorated, and if it is more than 20% by weight, it becomes difficult to form a stable liquid, which is not preferable.

る。As the polyoxyethylene polyoxypropylene block polymer, one having an average molecular weight of the polyoxypropylene portion of 600 to 2000 and a proportion of ethylene oxide of 10 to 40% by weight is preferably used. If the blending amount is less than 1% by weight or more than 10% by weight, the penetrating power becomes poor, which is not preferable. With this blending amount, an unexpected synergistic effect that the penetrating power becomes higher than that of the block polymer alone or the polyoxyethylene alkylphenyl ether nonionic surfactant alone is obtained.

い。The aliphatic carboxylic acid having 6 to 12 carbon atoms is a component necessary for keeping the detergent of the present invention in a stable liquid state in a wide temperature range from a low temperature of 0 ° C. or lower to a high temperature of 50 ° C. or higher. Specifically, hexanoic acid, heptanoic acid, octanoic acid, 2-ethylhexanoic acid, nonanoic acid, 3, 5,
5-trimethylhexanoic acid, decanoic acid, undecanoic acid,
Dodecanoic acid and the like can be mentioned. If the carbon number is less than 6,
An unpleasant odor becomes strong, and when it is more than 12, foaming becomes large, which is not preferable. If the amount added is less than 1% by weight, it becomes difficult to maintain a stable liquid state, and if the amount added is more than 20% by weight, the degreasing power decreases, which is not preferable.
