Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition used for cleaning a floor surface coated with a synthetic resin wax.

[0002]

2. Description of the Related Art Generally, synthetic resin wax is applied as a polish for the purpose of protecting the floor surface of a building. The floor surface coated with this synthetic resin wax is scratched by walking or the like over time. Occurs, or dirt adheres to the synthetic resin wax film, which impairs the appearance. For this reason, it is usual to reapply synthetic resin wax with cleaning to repair the floor surface.

This repair work is carried out by brushing the surface of the synthetic resin wax film applied to the floor surface with a cleaning agent. Contamination is caused not only on the surface of the wax film but also on scratches. Since it adheres to the inside as well, the cleaning work requires the work of removing the dirt and the surface of the scratched synthetic resin wax film at the same time.

Therefore, it is preferable that the detergent for cleaning the surface of the synthetic resin wax film has a property of dissolving the synthetic resin wax. Conventionally, a strong alkaline component is mainly contained, and a large amount of a surfactant and a builder are added thereto. The one contained in was used.

However, in order to restore the aesthetic appearance of the floor surface, cleaning with a cleaning agent is not sufficient, and synthetic resin wax must be reapplied.
Strong alkaline components of cleaning agents remain on the floor,
Even if the synthetic resin wax is reapplied, it may adversely affect the gloss, durability, stain resistance, etc. Therefore, the strong alkaline component remaining on the floor after the recovery of the wastewater used for cleaning the floor, 2-3 surfactants and builders
It was necessary to carefully wipe off with a rotating mop and the like, and it was further necessary to neutralize the residual alkali content with a weak acid component such as boric acid called a rinse agent.

In order to overcome such a situation, conventionally, a repair cycle of the floor surface is set as long as possible, or a method of scraping off the surface of the synthetic resin wax film using a polisher called high speed buffing, or spraying. A method called spray cleaning was used to remove stains by spraying a detergent that slightly dissolves the surface of the synthetic resin wax film, but in any case, the synthetic resin wax must be reapplied. There was no change, and the repair work required a considerable amount of manpower, time, and skilled technique.

[0007]

SUMMARY OF THE INVENTION The conventional cleaning agent requires a wiping operation and a rinsing operation after the cleaning is completed, and requires a skill and time for repairing the floor surface.

[0008]

DISCLOSURE OF THE INVENTION The present invention is a perfluoroalkyl phosphoric acid ester in which the alkyl group has a carbon number of C _{7 to} C ₁₃ and a phenol compound.
Phenol ethylene oxide adduct obtained by addition reaction of 1 to 5 mol of ethylene oxide with respect to mol, and the following glycol-based and alcohol-based solvents, namely ethylene glycol monobutyl ether or methyl ether 3-methyl-3-methoxybutanol mono- or di- An aqueous solution containing one kind or two or more kinds of propylene glycol monomethyl ether isopropyl alcohol was prepared.

[0009]

The cleaning composition of the present invention is used in an amount of 2-100.
Double the water dilution, dip this in water and use a mop squeezed to wash the floor surface coated with synthetic resin wax. Dirt on the floor surface adheres to the mop together with the cleaning components. The component forming the protective film remains on the floor surface.

By repeating the washing operation on a daily basis, essentially unnecessary substances contained in the synthetic resin wax film, that is, surfactants, preservatives, antifoaming agents, high boiling point solvents, etc. Is gradually removed and water repellent,
Oil repellency and abrasion resistance are imparted to the synthetic resin wax film.

On a heavily soiled floor surface, a 20 to 50-fold water-diluted solution of the cleaning composition of the present invention is applied to the floor surface,
After washing with a polisher and removal of dirty water, the synthetic resin wax is applied by drying.

The constituent composition of the present invention will be described below. (1) perfluoroalkyl phosphoric acid ester fluoroalkyl group in the molecule _{(CF 3} -CF ₂ -CF 2

Adsorbs to wax to form a protective layer, and imparts hardness and wear resistance as well as water and oil repellency.

(2) Phenol ethylene oxide adduct The compound has a property of slightly dissolving a synthetic resin wax and is used for repairing scratches and the like of a synthetic resin wax film. At this time, ethylene oxide is 1 to 1 with respect to 1 mol of phenol.
If it is up to 0 mol, it has a sufficient ability to dissolve the synthetic resin wax, but if it exceeds 5 mol, the dissolving power is weakened, and it is suitable for use as a cleaning agent for the surface film, but unsuitable for restoration. Therefore, ethylene oxide is preferably present between 1 and 5 moles.

(3) Glycol-based and alcohol-based solvents, which are used to enhance the solubility of the phenol ethylene oxide adduct compound in water and the cleaning ability,

The evaluation judgment method is a 10-point method, and 10 points is the best, and the results are shown in Table 4 (In Examples and Comparative Examples, a liquid diluted 50 times with tap water is used. X is a blank test only with tap water. I wiped it up).

[0024]

[Table 4]

[Explanation of Results] The synthetic resin wax used in the test is a wax which is generally used and has an average property such as heel mark resistance, scuff mark resistance or gloss. is there. The following is judged from Table 4 for this synthetic resin wax film. (1) The compositions of Examples 1 to 10 are repeatedly wiped up to enhance the physical properties of the film, and further, the adhered dirt is not deposited. (2) The blank is wiped up only with tap water, and the physical properties of the film are not extremely deteriorated, and the blank is rather effective. (3) The compositions of Comparative Examples 1 to 3 are conventional floor cleaners that deteriorate the physical properties of the coating by a strong alkaline substance or the like,
When it remains in the synthetic resin wax film, it is difficult to remove it because it adsorbs dust or the like, or black marks and dirt accumulate.

[Practical floor evaluation test-1] Average of about 3000 per day
The existing synthetic resin wax applied to the vinyl homogenia style flooring laid in the common corridor of an office building where people walk is peeled off and washed, and then 10 ml / m ² of the synthetic resin wax shown in Table 3 above is removed. On average 3
After repeated application, a place where walking frequency in the common corridor is considered to be about the same is selected, and each of the compositions of 1, 4 and 7 of the examples in Table 1 is addressed to 50 m ² respectively, ○ 1 gloss value average, and ○ 2 Conduct an evaluation test of the amount of scratches and black marks caused by walking,
The results are shown in Table 5 (Blank X was left without doing anything, Examples 1, 4, and 7 used a liquid diluted 50 times with tap water, and wiped with a squeezed mop once a day. A is the best for evaluation of scratches and the like).

[0027]

[Table 5]

[Actual floor evaluation test-2] Approximately 5000 per day
Example 7 in Table 1 was prepared by using a vinyl homogenia style floor material (three weeks elapsed after applying commercially available synthetic resin wax five times) laid in the entrance hall on the first floor of a tenant building where people walk.
And a composition obtained by diluting the composition of Comparative Example 1 in Table 2 with tap water to 50 times each, the cleaning with the floor pad of the automatic floor cleaning machine was continued once a day for 1 month, The results of visual inspection of the surface are shown in Table 6.

[0029]

[Table 6]

[Explanation of Results] (1) In the case of Example 7, the aesthetic appearance is completely maintained. (2) In the case of Comparative Example 1, it is necessary to peel and wash the already-applied synthetic resin wax and reapply the synthetic resin wax because the aesthetic appearance is deteriorated.

[Actual Floor Evaluation Test-3] The vinyl non-asbestos tile floor surface coated with the soiled synthetic resin wax was treated with the compositions of Example 7 of Table 1 and Comparative Example 1 of Table 2 respectively. The results of cleaning and repair work using a solution diluted 20 times with water are shown in Table 7 (the diluted solution is uniformly applied with a mop, left for 5 minutes, and then polished with a polisher).

[0032]

[Table 7]

[Explanation of Results] (1) In the case of Example 7, since the wiping operation after washing can be omitted, the synthetic resin wax film is not damaged and the repair operation is performed once. The application was completed. (2) In the case of Comparative Example 1, three times of wiping operations are required in consideration of the adverse effect on the synthetic resin wax to be applied later, and the synthetic resin wax film is also dissolved and removed by the strong alkaline component. The repair work requires two applications of synthetic resin wax.

[0034]

As described above, since the present invention does not contain a strong alkaline component, a builder, or a large amount of a surfactant, it does not require a water wiping operation or a rinsing operation after washing, and the composition of an already applied composition is not required. Since the resin wax film is less damaged, the life of the synthetic resin wax can be extended and the amount of the synthetic resin wax applied in the repair work can be reduced.

Therefore, no skilled technique required for cleaning and repair work is required, and the aesthetic appearance of the floor surface can be maintained in daily routine work, which contributes to cost reduction for cleaning management. It has the effect of being able to.
