Non-halogen detergent composition

Technical field

The present invention relates to an alcohol-based non-halogen-based cleaning which is effective for cleaning oils, rosin-based fluxes, adhesives, waxes, etc. attached to electronic parts, various metal surfaces, plastics and other surfaces and textiles. * Relating to agent composition.

Background art

Fluorocarbon has many excellent properties, such as low toxicity, non-flammability, chemical stability, does not attack plastics and other materials to be cleaned, retains strong permeability, and is quick-drying. So far, it has been used in a wide range of fields as a refrigerant for coolers and refrigerators, a propellant for sprays, a foaming agent for insulation materials such as urethane foam, and a cleaning agent for electrical and electronic parts, precision machinery, etc. Have been.

However, in recent years, the destruction of the stratospheric ozone layer by CFCs has been scientifically clarified, and five types of CFCs, such as CFC11, CFC12, and CFC113, have been regulated. Most of Freon 113, which accounts for about 50% of CFC products, is used as a cleaning agent. Although desired, so far there is no known material with excellent cleaning ability. ^

Disclosure of the invention

The inventors of the present invention have excellent properties of a conventionally known CFC-based cleaning agent, for example, excellent purifying power, chemical stability, etc., and do not contain any halogen such as chlorine and fluorine. We worked diligently to develop a detergent composition that does not break the environment and has enhanced cleaning performance. In the process, the present inventors have determined that an aliphatic or alicyclic alcohol having a specific structure or a derivative thereof is used as a solvent component, and a predetermined amount of a specific cyclohexylamine compound is added thereto. In addition, the present inventors have found that the cleaning performance is remarkably improved as compared with the case of using only the solvent component, and that a more general-purpose cleaning composition can be obtained in which the number of substances that can be dissolved and cleaned is increased. Further, an aqueous composition obtained by adding water to the detergent composition has excellent properties such as being less flammable, suppressing irritation and improving work safety. The present inventors have found that the composition is a detergent composition that can sufficiently achieve the intended purpose of being able to substitute for a fron-based detergent. The present invention has been completed based on such knowledge.

And the like. Among them, 2-ethylhexanol is preferable. These can be used alone or in combination of two or more. These may be alcohols derived from natural fats or oils, or synthetic alcohols derived from petroleum.

The number of moles of the alkylene oxide to be added to the alcohol is 1 to 20, and generally, the number of moles of the addition is preferably about 2 to 8.

When a product obtained by co-adding アルコール 0 and 共 0 to the alcohol is used, foaming of the cleaning composition can be suppressed.

It is essential to use a hexylamine compound represented by the formula:

Examples of such cyclohexylamine compounds include E0 adducts, P0 adducts, and coadducts of E0 and P0 of cyclohexylamine, each of which is used alone or in combination of two or more. Used. These compounds are known, or are prepared by adding a predetermined amount of alkylenoxide to cyclohexylamine using a basic catalyst such as caustic alkali, sodium methoxide, or the like while heating at normal pressure or normal pressure. It can be easily produced according to a commonly used method such as adding under pressure. When the cyclohexylamine E0 adduct is used among these high-opening hexylamine compounds, a detergent composition having very excellent dissolving power can be obtained. In addition, the -,-

The addition of kilenoxide increases the boiling point, improves the safety of the detergent composition, reduces the odor peculiar to cyclohexylamine, and improves the working environment. . In this case, the addition mole number of alkylenoxide is preferably about 1 to 6 moles. In particular, Echirenokishi de 2 mol adduct of Kishiruami down cyclohexane (XY-- CH ₂ CH ₂ OH, trade name "wander Mi emissions CHE - 20 P", New Japan Chemical Co., Ltd., hereinafter abbreviated as gamma CH EJ )) Is more practical because the resulting detergent composition has high detergency and low foaming properties.

Preferably, about 1 to 15 parts by weight is used. If the amount of the cyclohexylamine compound used is less than 0.1 part by weight, the ability to dissolve the substance to be washed and removed tends to decrease.Even if the amount exceeds 30 parts by weight, it is effective. The above-mentioned remarkable superiority is not recognized, and it is economically disadvantageous.In addition, in the case of certain objects to be cleaned, for example, in the case of surface-treated electronic components, etc. The surface protective film on the surface of the 1 ^

Such aqueous detergent compositions are aqueous solutions or aqueous emulsions, but are usually in the form of aqueous solutions. In such an aqueous composition, the amount of water can be appropriately selected depending on the application. Usually, the mixture is used in an amount of 2% by weight or more and less than 100% by weight, preferably 10 to 80% by weight. It is considered to be an aqueous solution containing at a concentration of about weight%. As a result, the safety of the environment and work can be improved without lowering the cleaning performance and not easily flammable. However, the amount is not limited to the above amount as long as a predetermined effect can be obtained. In the cleaning composition according to the present invention, a predetermined amount of the cyclohexylamine compound of the general formula (5) is used in combination with at least one of the alcohol solvents of the general formulas (1) to (4). As a result, each component acts synergistically, and is more permeable and dissolves in the material to be washed than when used alone. _r

For this reason, the fields in which a Freon-based cleaning agent has been conventionally used are, for example, electronic components such as printed wiring boards, ceramic devices, capacitors, liquid crystal display devices, electric components such as brushes and rotors, and bearings. It is ideal for cleaning organic oils that adhere to precision machine parts such as rings and chips, optical products used in cameras and eyeglasses, and automobile-related parts. In this case, metals, plastics, elastomers, and composites thereof are exemplified regardless of the material of the object to be cleaned. Further, the present invention can be widely applied not only in place of a chlorofluorocarbon-based cleaning agent but also in various fields in which other halogen-based cleaning agents have been used (for example, cleaning detergents).

However, the present invention is not limited to the following method.Generally, the non-aqueous or aqueous cleaning composition of the present invention may be brought into contact with a substance to be removed from an article to be cleaned, for example, if necessary. Then, the object to be cleaned is immersed in the cleaning composition adjusted to a temperature of about room temperature to about 80 for about 1 minute to several hours to swell the stain component. Alternatively, the washing solution may be stirred, rocked, or ultrasonic (10 seconds to

1 o'clock), or use these operations together to wash the dirt components. After washing, remove the detergent components by washing with water or rinsing with a lower alcohol having 1 to 4 carbon atoms, if necessary, and then dry.

As described above, the present invention provides the non-aqueous or aqueous cleaning composition of the present invention in contact with an article to be cleaned, the fats and oils, the mineral oil, the silicone oil, the waxes, the gin-based flatus, Another object of the present invention is to provide a method for cleaning the surface of an article contaminated with an organic substance such as a paraffin-based adhesive or a mouth-and-mouth adhesive.

(1) It shows high solubility for various substances to be removed by washing, and is applicable to a wide range of fields. 1 5 << _

(2) High safety, especially for aqueous compositions, with remarkable advantages in terms of reduced flammability and reduced odor.

(3) Good workability due to low foaming property.

(4) Unlike CFCs and other chlorine-based cleaning agents, they do not contain any halogen components, so there are no environmental problems.

(5) Compared to CFC-based detergents, it is less liable to volatilize and can be recovered and reused, which is cost-effective.
