The present invention relates to an emulsion composition for cleaning machinery and other various parts, and more specifically,
1.1.2-Trichloro-1.2.2-Trifluoroethane (hereinafter abbreviated as Freon 113) and water are used to emulsify water-in-oil type using multiple emulsifiers (surfactants).
The present invention relates to a composition in which the present invention is used in combination with the present invention, and a composition in which the composition is stabilized. Freon 113 has excellent properties as a cleaning agent, such as selective solubility, quick drying properties, and chemical stability, as well as nonflammability and low toxicity, and is widely used as a cleaning agent for precision machinery. However, pure Freon
113, it is difficult to remove water-soluble or water-dispersible stains, and a combination of washing with water or hot water is required. As a more preferable cleaning method in such cases, a method is known in which water is emulsified in Freon 113 in a w/o type and a composition is used which sufficiently removes water-soluble or water-dispersible stains. Various proposals have been made for compositions in which water is emulsified in Freon 113, and for emulsifiers used in such compositions, such as those disclosed in Japanese Patent Publication No. 44-8973, Japanese Patent Publication No. 31471-1973, etc. . However, in these compositions, the emulsifier is limited to one or two types, and when other substances are added, the amount of water emulsified decreases considerably, and furthermore, the amount of water emulsified decreases significantly even when the temperature decreases. .
It also has the disadvantage of corroding zinc and copper products. As a result of extensive research in view of the above-mentioned problems, the inventor of the present invention has found that by using multiple emulsifiers in combination to emulsify water into Freon 113, it is possible to emulsify a large amount of water with a small amount of emulsifier. Based on this knowledge, they discovered that the degree of temperature dependence on the amount of water emulsified can be made smaller, and that the addition of a specific stabilizer shows remarkable stability for zinc and copper products. As a result, the present invention was completed. That is, the first aspect of the present invention is a water-in-oil emulsion consisting of 0.25 to 50% by weight of water and at least 30% by weight of 1,1,2-trichloro-1,2,2-trifluoroethane, The following ingredients: 0.08-36% by weight of dodecylbenzenesulfonic acid isopropylamine salt and at least one of sorbitan fatty acid ester and polyoxyethylene sorbitan fatty acid ester.
This is a cleaning emulsion composition containing 0.02 to 9% by weight of seeds. The second aspect of the present invention is to add to the composition as stabilizers: 0.01 to 0.5% by weight of nitroalkanes, benzotriazoles, mercaptobenzimidazole,
At least one of mercaptobenzoxazole and mercaptobenzothiazole from 0.005
This is a cleaning emulsion composition containing 0.05% by weight. Sorbitan fatty acid ester and polyoxyethylene sorbitan fatty acid ester used in the present invention are compounds represented by the following formulas [] and [], respectively, and in the formula are saturated and unsaturated aliphatic hydrocarbons,
Further, l, m, and n shown in parentheses can take any integer value, but it is preferable that each has an HLB value of 6 to 14. In the present invention, dodecylbenzenesulfonic acid isopropylamine salt and sorbitan derivatives are used together as emulsifiers, but dodecylbenzenesulfonic acid isopropylamine salt alone has a relatively large maximum emulsification amount, but the stable emulsification range is narrow; By using sorbitan derivatives in combination, the maximum amount of emulsification can be increased, and at the same time, it is possible to emulsify stably in all regions up to the maximum amount of emulsification. Furthermore, the emulsification range can be expanded by adding a basic nitrogen-containing compound as an emulsion aid, and the addition of this compound is also preferred. As the basic nitrogen-containing compound used here, all of aliphatic primary, secondary, and tertiary amines, alicyclic amines, aromatic amines, ammonia, etc. can be employed. The amount added is preferably in the range of 0.00005 to 0.0005 mol per 100 g of the emulsion composition. In the present invention, the amount of water is preferably 0.25 to 50% by weight; if it exceeds 50% by weight, the emulsion changes from a water-in-oil type to an oil-in-water type, which is not preferred. Further, if the amount is less than 0.25% by weight, it is not practical or preferable for use in removing water-soluble or water-dispersible stains. In addition, to take advantage of the characteristics of Freon-113, it is necessary to
The amount of 113 must be at least 30% by weight, and dodecylbenzenesulfonic acid isopropylamine salt has a practical lower limit of 0.25% by weight of water and an upper limit of 50% by weight.
The amount range required to emulsify 0.05 to 12% by weight is applied. Although it is not particularly necessary to use 12% by weight or more from the viewpoint of water emulsion stability, there is no particular problem even if the amount exceeds this. Sorbitan derivatives are usually 20 to 30
Approximately % by weight is preferable, and the amount added is 0.01 to 4
Used in a range of % by weight. The second aspect of the present invention is a composition to which a stabilizer is added, especially for use in zinc products and copper products without corrosion, and includes benzotriazoles, mercaptobenzimidazoles, mercaptobenzoxazoles, and mercaptobenzothiazoles. It is characterized by the combined use of at least one of these and a nitroalkane. As the benzotriazole, methylbenzotriazole, 5-nitrobenzotriazole, etc. having an alkyl substituent can also be employed, but benzotriazole itself without a substituent is preferred. Furthermore, mercaptobenzimidazoles, mercaptobenzoxazoles, and mercaptobenzothiazoles having substituents can also be used, and each of these may be used alone or two or more types may be used in combination. It's okay. The amount of these stabilizers added is 0.005 to the emulsion.
The range of 0.05% by weight or less is preferable; if it is less than 0.005% by weight, the stabilizing effect will not be sufficiently exhibited, and if it is added more than 0.05% by weight, there is no particular benefit and there is no need for it. As the nitroalkanes used in the present invention, nitromethane and nitroethane are preferable, but 2-nitropropane and the like can also be used, and are usually selected from nitroalkanes having 1 to 3 carbon atoms, and the amount added. is 0.01 to emulsion
A range of 0.5% by weight is preferable; if it is less than 0.01% by weight, the effect cannot be obtained, and even if it is added more than 0.5% by weight, no particularly excellent effect can be expected and there is no need to add it. Next, the present invention will be explained in detail with reference to Examples. Examples 1 to 6, Comparative Examples 1 and 2 Dodecylbenzenesulfonic acid isopropylamine salt (DBS-salt), sorbitan monolaurate and polyoxyethylene sorbitan oleate as sorbitan derivatives were added to 100 parts by weight of Freon 113 in various amounts. amount of the composition, and furthermore, the composition
Add 0.01 parts by weight of a basic nitrogen-containing compound to 100 parts by weight to adjust the stable emulsification range of water to 10°C, 25°C, and 35°C.
It was measured with The results are shown in Table 1.
