In addition, adhesives and pressure-sensitive adhesives used in shoe manufacturing are leaked to the ends when pressing both adherends to be bonded, and contaminate the surroundings. In order to remove the silver pen applied to the need for an excellent cleaning ability remover is required to use toxic organic solvents such as toluene to harm the health of workers, damage the upper surface of the shoe and pollute the environment.

Therefore, in order to overcome this disadvantage, Korean Laid-Open Patent Publication No. 1988-0013548 has developed a multi-layer nail lacquer removal liquid prepared by mixing water and a solvent using a nonionic surfactant, reducing irritation to the user's skin and To increase the content was to give a moisturizing effect. However, there is a problem in that the content of the organic solvent is more than 60% and the water and the organic solvent is separated after a certain time. In addition, the Republic of Korea Patent Publication No. 1992-0009938 invented a peeling cleaning composition of the paint to effectively remove the paint, but since the toxic organic solvents, such as phenols, amines, benzene, etc. are contained in the composition, the worker has a protective tool There is a problem that can not be easily worked without.

 Recently, environmental regulations such as toluene regulation and restriction of use of toxic organic solvents have been strengthened for the safety of workers and consumers. Therefore, environmentally friendly cleaners, adhesives, coatings, silver pens, and manicures are required. .

Therefore, the present invention as a solution for solving the above problems as a solvent of the cleaning agent composition for removing adhesives, pressure-sensitive adhesives, adhesive for flooring, manicure, silver pen, wall wallpaper, etc. used in general home and shoe processes, etc. By minimizing low-toxic solvents, using a large amount of water, and using metals that can be dissolved in water to increase cleaning power, the ability to remove adhesive and adhesive contaminants, floor floor adhesives, manicures, silver pens, etc. The object of the present invention is to provide an excellent cleaning agent composition for removing adhesives and adhesives and silver pens, which are very excellent and have little harmful effects on the human body.

The present invention for achieving the above object is characterized by consisting of 5 to 15% by weight of nonpolar aliphatic hydrocarbon solvents and 20 to 58% by weight of alcohols, 35 to 55% by weight of water and 2 to 10% by weight of additives as a low toxicity solvent. The adhesive composition, the adhesive contaminant and the cleaning agent composition for removing the silver pen are regarded as a problem solving means.

And the non-polar aliphatic hydrocarbon solvent is used by selecting one or more from pentane, hexane, oxane, cyclohexane, dioxane,

The alcohols are used by selecting one or more from ethanol, methanol, propanol, hexanol, butanol and the like,

The additive is preferably used by selecting one or more from sodium hydroxide, magnesium hydroxide, potassium hydroxide and calcium hydroxide.

The present invention for achieving the above problem solving means is used to minimize the low-toxic solvent as a solvent of the cleaning agent composition for removing the adhesive, pressure-sensitive adhesive, floor adhesive, manicure, silver pen, wallpaper attached to the wall, Water is used, and by using metals that can be dissolved in water to increase the washing power, the washing power is not only excellent, but also less harmful to the human body without causing damage to the substrate to be cleaned and user's skin contamination. It is an advantage to be able to provide an environmentally friendly cleaning composition.

In order to achieve the above effects, the present invention relates to a cleaning agent composition for removing adhesive and adhesive contaminants and silver pens, which will be described below in detail with reference to a preferred embodiment of the present invention. It should be noted that in the following description, only parts necessary for understanding the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

The present invention is a low toxicity solvent, 5-15% by weight of a non-polar aliphatic hydrocarbon solvent, 20-58% by weight of alcohol, 35-55% by weight of water and 2-10% by weight of an additive, adhesive and adhesive contaminants, The present invention relates to a silver pen cleaning agent composition.

However, when both sides of the two adherends to be bonded by the adhesive / adhesive are squeezed to their ends, they are contaminated by the edges, or those applied and contaminated to areas that should not be applied are called adhesive / adhesive contaminants. .

The non-polar aliphatic hydrocarbon solvent, which is the low toxicity solvent used in the present invention, is used to swell and remove contaminants, and it is preferable to use 5 to 15% by weight. If the amount is less than 5% by weight, the cleaning power is reduced due to the inability to swell contaminants.If the amount is more than 15% by weight, it causes damage to the substrate to be cleaned and skin contamination, and it may be harmful to the human body due to the large amount of volatilized organic solvent. .

The nonpolar aliphatic hydrocarbon solvent may be selected from one or more selected from pentane, hexane, oxane, cyclohexane, dioxane and the like.

The alcohols, which are the low toxicity solvents, are used for washing aid and addition of water, and preferably 20 to 58% by weight. If the amount is less than 20% by weight, the compatibility with water is poor, the layer separation occurs, the washing power is reduced. When the amount of use exceeds 58% by weight, the content of the organic solvent is high, resulting in damage to the substrate, and the amount of volatilization of the organic solvent may be harmful to the human body.

The alcohols may be used by selecting one or more from ethanol, methanol, propanol, hexanol, butanol and the like.

The water used in the present invention is used to replace the part that minimizes the use content of the organic solvent, it is preferable to use 35 to 55% by weight. If the amount is less than 35% by weight, the organic solvent content is increased, so the cleaning power is excellent, but it is harmful to the human body, which is not preferable for home use.If the amount is more than 55% by weight, the compatibility with the solvent is reduced, so that the layer separation occurs. Detergency may be impaired. At this time, it is most preferable to use ion-exchanged water for water.

The additive used in the present invention is used to increase the washing power, Preference is given to using 2 to 10% by weight. If the amount is less than 2% by weight, the washing power is lowered, and if the amount is more than 10% by weight it may cause damage to human skin and substrate.

As the additive, metals that can be dissolved in water are used, and for example, one or more may be selected from sodium hydroxide, magnesium hydroxide, potassium hydroxide, calcium hydroxide, and the like.

The present invention is excellent in the ability to remove adhesives, pressure-sensitive adhesives, manicures, silver pens, wallpaper attached to the wall used in general home and shoe processes, and to minimize the solvent content in the composition is less harmful to the human body, environmentally friendly Phosphorus detergent composition.
