Definitions
- the present invention relates to a cleaning agent for cleaning dirt such as oils and fats adhering to metal parts, fluxes and finger prints adhering to electronic parts and the like.
- Conventional technology for cleaning dirt such as oils and fats adhering to metal parts, fluxes and finger prints adhering to electronic parts and the like.
- Degreasing cleaning of objects to be cleaned is because they are non-flammable and have no danger of ignition. Solvents have been used. However, recently, due to concerns about the destruction of the global environment and the effects on the human body, surfactants, aqueous cleaners containing alkali as a main component, hydrocarbon-based cleaners, alcohol-based cleaners, or third petroleums Conversion to semi-aqueous detergents in which hydrocarbons are dispersed in water using surfactants is in progress.
- the cleaning method using a water-based cleaning agent has problems such as high foaming property, insufficient cleaning property, a large amount of wastewater must be treated, and corrosion of the object to be cleaned.
- Both hydrocarbon-based cleaning agents and alcohol-based cleaning agents are flammable, have low flash points, and have a risk of ignition.
- semi-aqueous detergents have drawbacks such as being flammable when phase is separated, causing uneven washing, and having to drain a large amount of water.
- Japanese Patent Application Laid-Open No. 8-35992 requires propylene glycol alkyl ether, which has high compatibility with water, and propylene glycol alkyl ether, which has low compatibility with water, and three types of water.
- Detergents have been proposed. This detergent can be made nonflammable by appropriately selecting the amount of water, and since the glycol ether component having low compatibility with water has strong degreasing properties, each component is uniform. It has good detergency in the composition forming the phase and is very useful. However, this detergent has a composition area in which the above components form a uniform phase. The area was narrow, so there was still room for improvement.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, a specific imidazolidinone compound greatly promotes the solubility of a polar organic solvent having low compatibility with water in water.
- the present inventors have found that the degreasing property of the detergent is improved, and have completed the present invention.
- an object of the present invention is to provide a novel cleaning agent having a novel composition and having excellent cleaning action.

- the polar organic solvent preferably has a relative dielectric constant of 8 or more, more preferably 10 or more.
- the component (A) is a component that mainly imparts a degreasing property to a detergent.
- a polar organic solvent is rich in oil solubility and surface activity, so that the oil adhering to the surface of the object to be cleaned is directly dissolved and easily separated.
- the resulting detergent has insufficient compatibility with oil, and thus cannot obtain sufficient detergency.
- non-polar organic solvents such as normal paraffin have an extremely poor compatibility with water, so that the obtained detergent is not preferable because the uniformity is deteriorated.
- a known organic solvent having the above-mentioned properties can be used without limitation, but since it exhibits excellent detergency, it belongs to glycol ether compounds, pyrrolidone compounds, imidazolidinone compounds and the like. Preferably, a glycol ether compound is used.

- a cleaning agent having any of the compositions in the above-mentioned regions A and B can be used, but region A has a low water content and has bow I flammability. Therefore, a detergent having a composition of the non-flammable region B can be preferably used.
- the term "not flammable" means a liquid whose flash point cannot be measured by the Cleveland flash point measurement method (JISK2265).
- the cleaning agent of the present invention is used in a state where the three components of the components (A), (B) and (C) form a uniform phase.
- the region C in FIG. 1 can be significantly reduced. As a result, even if the concentration of the component (A) is increased, the uniformity of the liquid is maintained, and a cleaning liquid with significantly improved detergency can be obtained.
- the specific composition ratio of each component depends on the solubility in water depending on the type of each component. Although it cannot be determined unconditionally due to small differences, usually, component (A) is more than 25% by volume based on the total amount of component (A), component (B) and component (C). It is preferable that there is.
- the component (A) is preferably at least 50% by volume, particularly preferably at least 55% by volume.
- the component (B) is preferably at least 5% by volume, particularly preferably at least 10% by volume.
- the component (C) is preferably at least 5% by volume, and more preferably at least 20% by volume in order to make the detergent nonflammable.
- each of component (A), component (B) and component (C) is preferably not more than 90% by volume, more preferably not more than 70% by volume of component (A).
- (B) is preferably at most 70% by volume, more preferably at most 25% by volume, and the component (C) is preferably at most 70% by volume, more preferably at most 30% by volume. It is.
- a cleaning method using the cleaning agent of the present invention a known method can be employed without any limitation.
- a method of immersing the object to be cleaned with oil or fat in the cleaning agent a method of showering or spraying the cleaning agent on the object to be cleaned with oil or fat, or the like can be adopted.
- cleaning can be performed more effectively by using means such as ultrasonic cleaning, rocking, and stirring.
- the washing temperature is not particularly limited, but is preferably from 30 to 80 ° (: more preferably from 40 to 70 ° C, from the balance between the temperature dependence of the phase separation and the washability.
- the solubility of the oil in detergents There is a limit to the solubility of the oil in detergents, and the excess of the oil removed from the object to be washed becomes floating oil or sedimentation oil and is naturally separated from the detergent. For this reason, oil can be easily separated by treating the cleaning agent used for cleaning with an oil-water separation device, etc.
- the collected cleaning agent is not contaminated with oil and has a long life. Has high cleaning ability.
- the solubility of the oil in the detergent can be easily adjusted by the content of the component (c), that is, water. That is, by decreasing the content of the component (C), a cleaning solution having high oil solubility but high degreasing property can be obtained. Conversely, by increasing the content of the component (C), the solubility of the oil can be increased. And a liquid with good oil-water separation properties can be obtained.
- the object to be washed is washed using a solution containing a small amount of the component (C) as a washing solution, and then, in a subsequent washing tank, a solution containing a large amount of the component (C) is used as a washing solution. It is efficient to perform the cleaning by a method of cleaning the cleaning object. According to such a washing system, the oil is easily removed from the object to be washed with higher washing performance, and the removed oil is easily separated out of the system, which is preferable.
- All components of the cleaning agent of the present invention are an organic solvent and water, and there is no evaporation residue. Therefore, even when the cleaning agent is dried while adhering to the object to be cleaned, salts and the like do not precipitate as in the case of the aqueous cleaning agent, and do not adversely affect the object to be cleaned.
- the cleaning agent of the present invention has a wide composition range in which each of the components (A), (B) and (C) forms a uniform phase, and is particularly suitable for the component (A) having excellent degreasing properties, namely, water.
- a composition region containing a large amount of a low-compatible polar organic solvent is wide. Therefore, a detergent containing a large amount of the component (A) and having excellent detergency can be easily produced, which is particularly advantageous when producing the non-flammable detergent.
- component (B), that is, the imidazolidinone compound itself represented by the formula (I) itself also has an effect of improving detergency in the entire composition forming a uniform phase in order to improve degreasing properties. .
- phase diagram of a three-component system in which propylene glycol monobutyl ether as component (A), 1,3-dimethyl-2-imidazolidinone as component (B), and water as component (C) are mixed in 60 is shown. It was measured. The results are shown in FIG.
- a phase diagram of a three-component system at the same temperature when the component (B) was replaced with dipropylene glycol monomethyl ether in the above composition was measured. The results are shown in FIG.
