2. Description of the Related Art In recent years,
Although destruction of the ozone layer has been regarded as a problem from the viewpoint of environmental protection, CFCs (chlorofluorocarbons) and HCFs conventionally used as refrigerants for refrigeration cycle systems have been considered.
C (hydrochlorofluorocarbon) is subject to regulation as one of the substances causing destruction of the ozone layer, and HFC (hydrofluorocarbon) is being used as a refrigerant instead of these. Along with this, a lubricating oil (refrigerating machine oil) used for a compressor must be used in accordance with the refrigerant, and a lubricating oil based on an oxygen-containing synthetic oil such as an ester has been generally used. On this occasion,
Blockage trouble of the refrigeration cycle system based on the residue attached to the surface of the metal part may occur. Examples of the residue on the surface of the metal part include lubricating oil (metal working oil) used for cutting, grinding, pressing, and the like, rust preventive oil applied when shipping the metal part, and the like.
Normally, metal parts are manufactured through metal processing such as cutting, grinding, and pressing, but the metal working oil used in the metal working process contains extreme pressure agents that cause rust. In many cases, rust is likely to occur on metal parts to which this adheres. Therefore, usually, rust-preventive oil is applied while the metal-working oil is adhered, or after the metal-working oil is easily washed and degreased using kerosene, etc., the rust-preventive oil is applied and shipped. Is done. Anti-rust oil is a metal salt of sulfonic acid, an ester of an oxide of waxes as an additive,
Metal salts of wax oxides, petrolatum, waxes and the like are used alone or in combination, and these often cause blockage of the refrigeration cycle system. Therefore, it is necessary to wash and degrease the rust preventive oil during the assembly process of metal parts, but insufficient cleaning and degreasing of the rust preventive oil may cause a blockage trouble of the refrigeration cycle system. Often. In addition, the removal of metalworking oil and wear during metalworking is performed at the same time as the rust-prevention oil washing and degreasing processes.However, even if metalworking oil remains on metal parts, blockage of the refrigeration cycle system may occur. Cause. For this reason, it is necessary to sufficiently wash rust preventive oil, etc., but in particular, the use of chlorine-based and fluorine-based solvents, which have been used as conventional cleaning agents, is restricted from the viewpoint of environmental protection. At present, solvents with less detergency than halogenated hydrocarbon solvents are used.
Degreasing required considerable effort. For this reason, there is a demand for shipping metal parts without applying rust preventive oil after metal working. As one of the methods, thorough cleaning after metal processing can be considered so that the metal parts can be shipped without applying rust-preventive oil and the shipped metal parts can be directly used in the assembling process. The cleaning agents used in this case include not only oil components and wear powder and chips from metal working, but also corrosive substances generated by the reaction of extreme pressure agents in metal working oil with the surface of metal parts. It is required to have excellent removability, but a cleaning agent having such excellent performance has not yet been obtained. Accordingly, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a cleaning composition capable of cleaning and degreasing metal parts to such an extent that the application of rust preventive oil is not required. It is in.

[0003]

Means for Solving the Problems As a result of intensive studies aimed at solving the various problems as described above, the present inventors have found that a cleaning composition having a specific composition has a high efficiency in removing residues. It has been found that if the cleaning is performed using the cleaning composition of the present invention after the metalworking step, the metal parts can be shipped without applying rust-preventive oil, and the present invention has been completed. That is, the cleaning composition of the present invention has a temperature of 40 ° C.
A cleaning composition having a kinematic viscosity of 0.5 to 50 mm ² / s, wherein (A) at least one selected from mineral oil and synthetic oil is used as a base oil, and based on the total amount of the composition, (B) 0.1 to 10% by mass of at least one compound selected from the following: (B-1) amine salt of fatty acid (B-2) alkyl or alkenyl succinic acid derivative (B-3) phosphate or It is characterized by containing a phosphite.

g, iron, aluminum and copper wires were further added. Thereafter, the upper portion of the glass tube was melted and sealed, and kept at 175 ° C. for 100 hours. The evaluation was performed based on the amount of sludge generated and the presence or absence of discoloration of the three types of metal wires. The metal wire is 1.6mm thick
φ, having a length of 50 mm was used. [Low-temperature precipitation test] In a Pyrex glass tube having an inner diameter of 10 mm, 9 ml of refrigerant and 1 ml of refrigerating machine oil were taken, and 10 mg of 30 mg of sample oil which had been subjected to nonvolatile differentiation was added.
Thereafter, the upper part of the glass tube was melted and sealed, and the mixture was stirred well and kept at -20 ° C for 72 hours. The evaluation was carried out with or without cloudiness. The sample oil subjected to volatilization is JIS
It was obtained by applying oil to a test piece in the same manner as in the wet test method of K2246, and collecting the sample oil remaining on the test piece after 24 hours. The evaluation criteria in the above-mentioned shield tube test and low-temperature precipitation test were as follows. iron,
Regarding the degree of discoloration of copper and pure aluminum, A = no discoloration, B = very slight discoloration, C = slight discoloration,

Using the rust preventive oil and the detergent composition (Examples 1, 6, and 10) prepared as described above, the performance when rust preventive oil was applied after cleaning by the following method was evaluated. First, chloride and dust were attached to the test piece in the same manner as in the above-mentioned method 2-1). This test piece was cleaned using the cleaning composition according to the method described in 2-2).
After that, when the rust inhibitor oil was applied as it was without performing degreasing with kerosene and n-hexane, and when the rust inhibitor oil was applied after performing the degreasing with kerosene and n-hexane, the evaluation of the rust inhibitory property was performed. I did it. The rust resistance was evaluated by the number of days until rust was generated in a wet test specified in JIS K2246 "rust prevention oil". However, the evaluation was performed every three days, with a maximum of 30 days.
Table 6 shows the results. Next, assuming that the rust inhibitor oil was overcoated without degreasing the detergent, a sample oil was prepared in which 10 parts by weight of each detergent composition was blended with 90 parts by weight of each rust inhibitor oil composition. For the sample oil, the same evaluation test as in the above 3) Effect of the cleaning composition on the refrigerator system was performed. The evaluation results are shown in Table 7.

[Table 7]

As is clear from Tables 1 to 7, all of the rust-preventive oil compositions of Examples 1 to 13 according to the present invention effectively remove rust-causing substances from the metal surface.
It has the effect of suppressing the generation of rust, and a more effective rust prevention effect can be expected by combining rust prevention oil. Further, in Examples 3 to 10, the detergent itself has an effect as a rust-preventive oil. Further, Examples 1, 2, 11,
12 and 13 are considered to have good compatibility with the metal in the system even when mixed into the refrigerator oil and do not cause problems such as blockage of the capillaries. It can be seen that the adverse effects are almost eliminated. On the other hand, Comparative Example 1, which does not contain the component (B), is poor in rust prevention due to cleanability.

[0059]

In summary, according to the present invention, the cleaning and cleaning of metal parts is performed to such an extent that the application of rust inhibitor oil is not necessary.
A cleaning composition that can be degreased is obtained.
