Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaner liquid for removing stains, and more specifically, the present invention relates to a cleaner liquid for removing dirt.
It concerns a cleaning solution used to bathe and remove oil-based stains from temple surfaces.

Today, the number of general electrical appliances and obsolete equipment, both for home and commercial use, is increasing and reaching 7Jll. In addition to these, materials such as plastic and steel are often used as exterior materials due to their easy processability. Although these materials give the impression of being clean at first glance, they are surprisingly susceptible to stains from various oily substances such as cigarette smoke and oil from hands and fingers.

Furthermore, at home, children often draw mischievous drawings on window glass and plastic cabinets using various writing instruments, and erasing these is also a problem. Generally, these substances can be removed or erased using various detergents or
A commonly used method is wiping using various organic solvents as solvents to dissolve the dirt. In the former case,
A solution prepared by dissolving a small amount of surfactant in water is often used, but in this case, the cleaning power is extremely weak.In the latter case, benzene or thinner is used as a solvent for dissolving dirt. However, especially when the material to be cleaned is subjected to positive action, the material itself is also affected by the solvent's dissolving power, leaving deformation and keloid-like traces due to warping.
There are many accidents that occur, and there is no way to leave it in the hands of the companies that implement them, or the large professionals who are responsible for all of them.
It wasn't common.

Under these circumstances, in recent years, plastic materials have also been used, but organic solvents (called rich solvents) that can dissolve oil-based stains well are rarely used on plastics. There are even cleaners on the market that can be diluted with solvents (called solvents) to reduce the effects of dirt on all plastic materials.
These are culm-like products that are effective only in removing some of the light oils and dirt from stains. Therefore, as mentioned in Part 11, all traces of crayon, magic ink, and paint markers drawn on the TV cabinet etc. were completely erased, paint traces stuck to the steel desk, traces of adhesive tape, and glass JP. The erasing section of the marking paint picture drawn on the transparent acrylic board.
Even though it was impossible to solve these problems, the appearance of a cleaner liquid that can be dissolved or removed without any problems has been long awaited.

Based on the above, and as a result of research, the present invention has found that when at least one of a pyrrolidone compound and mesityl oxide is used as the solvent-rich component in a cleaner liquid consisting of a solvent-rich and a concentrated solvent, We have found a solution that can be used as a cleaner liquid with performance that meets all Fc children.

The cleaner liquid of the invention is N-vinylpyrrolidone, N-
A pyrrolidone compound selected from methyl-2-pyrrolidone and 2-pyrrolidone and at least one of medinal oxide is mixed with an ester solvent or a ketone solvent, and both solvents are mixed into a solvent. The semitone dissolved in the color is a characteristic, and the magic ink acid marker and wyp+t that use the coloring v/J* dye.
Paint-type marker for v. Furthermore, it has excellent dissolving power in a wide range of applications such as glue for adhesive tapes, but it also has the desirable property of not having any adverse effects on Plastirif materials. .

The ester solvents referred to in the present invention include methyl cellosolve,
In addition to cellosolve yarn solvents such as ethyl cellosolve, acetyl cellosolve, and 7g nil cellosolve, carbitol yarn solvents such as methyl carbitol and ethyl carbitol are used.

This refers to esters of the Abashi group, which are represented by propyl acetate, butyl acetate, isoamyl isopropionate, ethyl propionate, butyl isopropionate, lacquer isobutyl, ethyl isopariate, and the like. Ketone thread solvents are single-chain or cyclic ketones such as diethyl ketone, methyl isobutyl ketone, dibutyl ketone, and cyclohexanone.
A temperature between 70° C. and 200° C. is preferable in that it has a reasonable rate of evaporation, and this, along with those described below, is of great significance in terms of its usability. In addition to water, alkylene glycols such as ethylene glycol and propylene glycol can be used as antidepressants. property tools,
1I W5 group alcohols such as 3342-butanol and 4-methyl-2-pentanol. Furthermore, kerosene, ligroin, isoparaffinic kerosene, petroleum fractions or synthetic petroleum fractions having a boiling point of 70°C to 270°C at normal pressure can also be used.

In addition, the ratio of rich solvent to dissolved solvent is not uniform depending on the type of rich solvent and poor solvent, but in experiments conducted with the present invention,
The accuracy was between 35 and 50%, and the results were good for all 7 times.

The uninvented cleaner can be used by soaking a piece of cloth or towel in it and wiping off all the dirt and what you want to erase. It can also be used by wiping off the raised areas with a piece of cloth or paper.

Examples will be described below along with comparative examples. Furthermore, all of the slopes are heavily rutted.

Example-1 Methyl carbitol 1 to 1, dibutyl ketone 1.5 rei 5
, N-vinyl-2-pyrrolidone (1.8 s) was dissolved in kerosene (9b1) and secondary butanol (3 to A), the distillation range of which was from 90 DEG C. to 180 DEG C., to obtain an inventive cleaner solution. The dirt was removed by wiping with a piece of cloth.

Example-2 Phenylcellosolve 1.5M, mesityl oxide i,
am1 ethyl isovarate 1 sled distillation range is 120
Isoparaffin yarn kerosene BM from ℃ to 260℃
S, '-Methyl-2-pentanol was dissolved in 36° to obtain the cleaner liquid of the present invention (11-). Spray this on the dirt and stains, wipe with a Te (41/Shijihaber), Example 3 to see how stains were removed 1.5 parts of acetyl cellosolve, 1.2 parts of 2-pyrrolidone, and 1.8 parts of butyl acetate were added to 3 parts of water, 6 parts of isopropyl alcohol, and 1 part of ethylene glycol. , L is the cleaner liquid of the present invention.This 1. was applied to a stained area with a brush, and wiped off with a piece of cloth to see how well the stain was removed.

Example-4 Methyl cellosolve 1s1 mesityl oxide No. 1.1,
N-vinyl-2-pyrrolidone J2 vinegar, 0.1 m of ethyl propionate were mixed with 3 parts of propylene glycol, 5 tn of isopropyl alcohol, and 3 mKmM of water, and 1 ζ of the cleaner solution of the present invention was added. Book 11 Filled in a top pen, wiped off any stains on the felt with ML and tea paper, and the stains were removed and the sweat was removed.

Example-5 Ethyl cellosolve 18i1, mesityl oxide 1.1

Isoparaffin thread kerosene 4ftlS from ℃ to 180℃
The cleaner liquid of the present invention was obtained by dissolving in petroleum-based ligroin 281) whose distillation range was 75°C to 9240°C. This liquid was applied to the stain with a brush and wiped off with a piece of cloth to see how well the stain was removed.

Comparative Example-1 The same procedure as Example-1 was carried out except that N-vinylpyrrolidone in Actual tx Example-1 was replaced with gold medal dibutyl ketone, and a comparison cleaner liquid was used to test the stain removal effect. The same procedure as in Example-1 was also carried out.

Comparative Example-2 The procedure of Example-4 was repeated except that mesityl oxide gold methyl cellosolve was replaced with propyl N-vinyl-2-pyrrolidone, and a comparative example was prepared. A test for the dirt removal effect was also conducted in accordance with Example 4 using the cleaner liquid.

Comparative Example-3 In Example-6, mesityl oxide was replaced with methyl isobutyl ketone and N-methyl-2-pyrrolidone was replaced with ethyl pusipionate. A cleaner solution was obtained. A test for dirt removal effect was also conducted in accordance with Actual Axis Example-6.

As mentioned above, regarding the cleaner liquid 6111I according to the present invention and the three comparison liquids, the removal performance of 115 was evaluated as A.
