る事が明瞭であった。[Means for Solving the Problems] The present invention has been made by focusing on such conventional problems. That is, 100O or more and less than 55.0% by weight of a saturated monohydric alcohol having 1 to 3 carbon atoms in the composition, and 1.0% or more and less than 5.5% by weight of HL in the composition.
B5-8 polyoxyethylene alkyl ether type nonionic surfactant and composition 40.0% by weight Sou 1 85
．． A cleaning composition characterized in that it consists of less than 0% by weight of water. (Requirements constituting the means) The saturated monohydric alcohol having 1 to 3 carbon atoms used in the present invention includes methyl alcohol, ethyl alcohol, isopropyl alcohol, etc., but ethyl alcohol and isopropyl alcohol are preferable from the viewpoint of safety. Its content is 10.0% by weight or more and less than 55.0% by weight. When the content is less than 10% by weight, the cleaning performance for a wide range of contamination is poor, and when it is 55.0% by weight or more, it is often subject to regulations under the Fire Service Act, and its handling is limited. receive. The polyoxyethylene alkyl ether type nonionic surfactant is obtained by addition polymerizing a predetermined amount of ethylene oxide to a higher alcohol having 6 to 22 carbon atoms to give an ILB of 5 to 8. When the HLB is less than 5, the detergency, especially the processing oil detergency, is poor, and when the HLB is more than 8, the detergency generally decreases. In addition, the content is 1.0% by weight.
If the content is less than 5.5% by weight, cleaning performance is generally poor when it is less than 1.0% by weight, and if it is more than 5.5% by weight, it is often subject to regulations under the Fire Service Act, and its handling is limited. Furthermore, the cleaning composition of the present invention may contain amines, for example, alkanolamines include monoethanolamine,
Examples include jetanolamine, triethanolamine, etc. Alicyclic amines include cyclohexylamine, dicyclohexylamine, etc. Polyoxyalkylene alicyclic amines include addition polymerization of 1 to 20 moles of ethylene oxide, propylene oxide, etc. to cyclohexylamine, etc. Alkylamine is an amine having an alkyl group having 6 to 22 carbon atoms, and polyoxyalkylenealkylamine is an amine obtained by addition polymerizing 1 to 20 moles of ethylene oxide, propylene oxide, etc. to the above alkylamine. Examples of the alkyl group constituting dimethylalkylamine include those having 6 to 22 carbon atoms. There is no problem in using these amines alone or in combination. Furthermore, when the amine is used in combination with the nonionic surfactant, the content in the composition is 1.0% by weight or more and 5.5% by weight.
(When the content is less than 1.0% by weight, the cleaning performance is generally poor, and when it is more than 5.5% by weight, it is often subject to regulations under the Fire Service Act, and its handling is difficult.) The cleaning composition of the present invention comprises the above-mentioned saturated monohydric alcohol having 1 to 3 carbon atoms, a polyoxyethylene alkyl ether type nonionic surfactant having an HLB of 5 to 8, and optionally the above-mentioned amines. It can be mixed with water.The material to be cleaned is then cleaned in this cleaning composition using a cleaning method such as immersion, ultrasonic waves, spraying, etc. It belongs to the alcohol-based cleaning agents.Although alcohol normally has an excellent cleaning effect for certain limited contamination, it is classified as a dangerous substance and requires a lot of effort in its handling and storage. Furthermore, adding a certain amount (40% or more) of water to alcohol greatly reduced the cleaning performance, which was a constraint on the practical application of alcohol-based cleaning agents.However, , alcohol and water, as well as a specific nonionic surfactant, and if necessary, amines. ■If the content of each component of the cleaning composition of the present invention is appropriately selected, it will be applicable to the Fire Service Act. ■ Cleaning properties comparable to 100% alcohol ■ Practical cleaning effects can be obtained for a wide range of contamination. [Examples] Table 1 shows examples. and the composition of the cleaning composition used in Comparative Examples.Each cleaning effect experiment was conducted and evaluated.The results are shown in Table 2.(Left below blank)Effect Example-1 Contaminants (Dissolved) Each of the cleaning compositions shown in Appendix Table 1 was mixed with ■ Primary flux ■ Secondary flux ◎ Oil-based low-viscosity oil-based cutting oil /
w t ) was added, and after immersion for 30 seconds, the dissolution state was evaluated in 3 stages: ○ completely dissolved 81 fraction x insoluble. Effect example-2 High-viscosity oil-based cutting oil cleaning Parts with high-viscosity oil-based cutting oil were immersed in each of the cleaning compositions shown in Table-1 at 60°C (30°C for CFC113) for 30 seconds and subjected to ultrasonic cleaning. The residual oil content after drying was measured by ultraviolet spectrophotometry, and the detergency (%) was evaluated using the following formula. After extracting and measuring the weight, the durability and cleaning performance (%) were calculated using the following formula.
was evaluated. (Leaving space below) After adding 5 (wt/wt)% of oil-based rosin flux to each cleaning composition shown in Table 1, the flux-adhered model substrate was immersed at 30°C for 1 minute, ultrasonically cleaned, and the remaining flux was removed after drying. The cleaning composition of the present invention exhibits excellent cleaning properties when compared to carbon tetrachloride. On the other hand, the comparative cleaning agent (a) will be regulated in the future as an ozone depleting substance, and the cleaning agent (b) has pollution selectivity.
(8) has extremely poor cleaning performance, (d) 1 (e) has poor cleaning effect because the HLB of the nonionic surfactant is outside the scope of the claims of the present invention, and (f) is the scope of the claims of the present invention. Nonionic surfactants other than
It was clear that F) had a low proportion of group C and d among the constituent components (inferior cleaning effect), and F) had a small amount of group A (large amount of group B), resulting in poor cleaning effect.
本発明洗浄剤組成物はオゾン層破壊に斯る懸念なく、消
防法にかかる規制に適用可能で、且つ汚染選択性の無い
優れた洗浄効果を発揮出来る。The cleaning composition of the present invention has no concern about ozone layer depletion, can be applied to regulations related to the Fire Service Act, and can exhibit excellent cleaning effects without pollution selectivity.
