Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、新規な洗浄用組成物に関する。詳しくは、無
機粉を含有する油類に対して優れた溶解性を有する洗浄
用組成物である。TECHNICAL FIELD The present invention relates to a novel cleaning composition. Specifically, it is a cleaning composition having excellent solubility in oils containing inorganic powder.
塩化メチレンは、油類等が付着した物品の洗浄に対して
優れた洗浄力を有し、しかも低沸点であるために乾燥が
容易な点で、金属の脱脂洗浄剤を始めとする各種洗浄剤
に広く使用されている。Methylene chloride has excellent detergency for cleaning oily objects, and because it has a low boiling point, it is easy to dry, so various cleaning agents including degreasing agents for metals are included. Widely used in.
しかしながら、塩化メチレンは、高濃度の無機粉を含有

の洗浄において、その洗浄効果が低く使用上問題があっ
た。However, methylene chloride tends to have a significantly reduced detergency with respect to oils containing a high concentration of inorganic powder. For example, hardened oil containing inorganic powder such as metal powder and abrasive powder, oils such as beef tallow, paraffin, and cutting oil adhere firmly to the metal surface treated by oily polishing, and the cleaning of the oils However, the cleaning effect was low and there was a problem in use.
本発明は、かかる問題に鑑み成されたもので、無機粉を
含有する油類に対しても高い溶解性を有し、且つ洗浄後
における乾燥の容易な洗浄用組成物を提供する。The present invention has been made in view of the above problems, and provides a cleaning composition that has high solubility in oils containing inorganic powder and that can be easily dried after cleaning.

り金属に対して充分な洗浄効果が得られない。The alcohols in the present invention are not particularly limited, but are preferably used because they exhibit a particularly excellent effect in improving the detergency of a cleaning composition capable of obtaining a lower monohydric alcohol having high solubility in water. It Examples of such alcohols include methyl alcohol, ethyl alcohol, isopropyl alcohol, n-propyl alcohol, isobutyl alcohol, sec-butyl alcohol, tert-butyl alcohol, n-butyl alcohol and the like. These alcohols are used alone or in combination of two or more. The amount of alcohols added to methylene chloride is 3 to 30% by weight, preferably 4 to 15% by weight. When the amount of alcohol added is more than the above range, the solubility of the cleaning composition in oils decreases, and as a result, the cleaning power for inorganic powder also decreases. Moreover, the flash point is lowered and the danger is increased. On the other hand, if the amount added is less than the above range, the affinity of the cleaning composition with the inorganic powder deteriorates, and a sufficient cleaning effect on metals cannot be obtained.

的でない。As the nonionic surfactant in the present invention, known nonionic surfactants can be used without particular limitation. Typical nonionic surfactants include polyoxyethylene alkyl ether, fatty acid alkylolamide, polyoxyethylene alkylamine, polyoxyethylene fatty acid ester, glyceryl monostearate, polyoxyethylene alkylphenyl ether, sorbitan fatty acid. Examples thereof include esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene polyoxypropylene, and the like. These nonionic surfactants are used alone or in combination of two or more. Among them, the embodiment in which three kinds of polyoxyethylene alkyl ether, fatty acid alkylolamide, and polyoxyethylene alkylamine are used in combination is particularly effective and preferable. The amount of the nonionic surfactant added to methylene chloride is 1 to 10% by weight, preferably 2 to
It is 10% by weight. When the amount of the nonionic surfactant added is less than the above range, the detergent composition has a poor affinity with the inorganic powder and the cleaning effect is reduced. Further, even if the amount added is more than the above range, the effect will reach the ceiling and it is not economical.

分離してしまい、使用上問題となる。In the present invention, water is added in a proportion of 0.4 to 2% by weight with respect to methylene chloride. When the amount of water added is less than the above range, the affinity of the cleaning composition for the inorganic powder is lowered, and a sufficient cleaning effect cannot be obtained. Further, when the amount added is more than the above range, the solubilizing agent is added and the layers are separated into two layers, which is a problem in use.
本発明においては他の添加剤、例えば安定剤、可溶化剤

To do. The mechanism by which the above-mentioned cleaning composition exerts such an excellent cleaning effect is not clear, but the inorganic powder is maintained while maintaining the dissolving power of methylene chloride for oils by the interaction of the above-mentioned specific additive components. It is presumed that this is because the affinity for
