Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to floor cleaners. More specifically, the present invention relates to a floor cleaning agent for cleaning the surface of a floor coated with a synthetic resin floor polish.

BACKGROUND OF THE INVENTION Polishing agents containing synthetic resin as an active ingredient (hereinafter referred to as resin wax) are frequently used as floor polishing agents for buildings.

By the way, the floor surface immediately after applying resin wax has a beautiful shiny appearance, but as time passes, scratches and dirt from walking will accumulate on the resin wax film, spoiling its appearance. Wash thoroughly. As described later, the surface layer of resin wax is removed by this cleaning, so after cleaning, resin wax is applied to repair and restore the aesthetic appearance. This type of cleaning and repair application can usually be repeated dozens of times, and when it finally becomes impossible to satisfactorily restore the appearance, the resin wax is completely removed using a removal cleaning agent. , new resin wax has been applied.

Cleaning to remove the surface of the resin wax is performed by brushing the floor surface with a cleaning agent. Since dirt adheres not only to the surface of the resin wax but also in the scratches, cleaning is performed to remove the dirt and the surface layer of the resin wax film with the scratches.

Therefore, the cleaning agent must have an appropriate dissolving power for resin wax. If this dissolving power is weak, it will take a long time to remove the stain, and even if cleaning takes a long time, the stain will not be completely removed. may not be able to be removed. If cleaning and repair application are repeated with even the slightest amount of dirt remaining, the film will darken after just a few repetitions, and the beauty will not be fully restored.

Conventionally, cleaning agents containing acrylic synthetic resin as a main component have been used as resin waxes, and there have been almost no problems with cleaning.

However, in recent years, resin waxes containing urethane-based synthetic resins as an active ingredient (hereinafter referred to as urethane-based resin waxes) have been developed, and the following cleaning problems have arisen.

Urethane resin wax has a strong film and is less susceptible to scratches and dirt than conventional resin waxes, so the above-mentioned cleaning and repair application cycle can be significantly lengthened. The number of times cleaning and repair application can be repeated until removal can be significantly increased.

Since urethane resin wax has the above-mentioned properties, it is used for floors of shopping floors and terminal buildings where there is a large amount of foot traffic and where aesthetic requirements are high.

However, cleaning the floors of these buildings must be completed within a certain amount of time, and conventional cleaning agents have weak cleaning power, so they cannot completely remove stains from urethane resin wax within a short period of time. If you have no choice but to clean the area and apply resin wax, apply a cleaning agent only to areas that are still dirty (such stains tend to remain in areas where people walk a lot). The method used is to completely remove the resin wax by applying it, and then reapplying the resin wax.

This method is cumbersome to work with, and the frequently used cleaning agents damage the adhesive on the flooring, making it easy for the flooring to warp or peel.

Attempts have been made to add 5% by weight of sodium hydroxide or potassium hydroxide to conventional detergents in order to increase their ability to dissolve resin wax films. Although it was possible to completely remove the stain by this method, the remaining resin wax film was severely softened and wg4, and the beauty could not be restored even with repair application of resin wax. Further, a cleaning agent in which 50% of a glycol solvent was added to a conventional cleaning agent was tried, but the results were similar to those obtained when sodium hydroxide or potassium hydroxide was added.

As mentioned above, urethane resin wax has excellent durability and is suitable for use on the floors of buildings that are frequently walked on, but since there is no suitable cleaning agent for this wax, tedious cleaning work is forced. Moreover, there remains the problem that the flooring material is easily damaged by cleaning.

Problems to be Solved by the Invention In view of the above-mentioned current situation, it is an object of the present invention to provide a floor cleaning agent that can efficiently clean floors coated with urethane resin wax.

Means for Solving the Problems In order to achieve the above object, the present inventors have conducted extensive research and found that 2 moles to 6 moles of ethylene oxide in cyclohexylamine
The present invention was completed by discovering that a composition containing a molar adduct and a specific glycol solvent in a specific ratio has an excellent cleaning effect on urethane resin wax stains.

That is, the present invention.

(a) Ethylene oxide adduct of cyclohexylamine obtained by reacting 2 to 6 moles of ethylene oxide with 1 mole of cyclohexylamine; (b) Glycol belonging to the following groups (a) to (d). One or more types of solvents (a) Propylene glycol monomethyl ether (b) Dipropylene glycol monobutyl ether (c) Ethylene glycol monobutyl ether (d) 3
- contains methyl-3-methoxybutanol and (c) water, and the weight ratio of component (IL) to component (b) is 6/
1 to 1/6 of the floor cleaning agent.

The configuration of the present invention will be explained in detail below.

(Components) (a) Hyethylene compound of cyclohexylamine In the ethylene oxide adduct of cyclohexylamine, the number of moles of ethylene oxide added must be 2 to 6 moles per mole of cyclohexylamine. If it is less than 2 moles, it is inappropriate because it has a strong odor and toxicity, and also has an adverse effect on the skin of workers. When the number of moles added exceeds 6 moles, the detergency of the detergent decreases.

(b) Glycol solvents Reprinted versions of the glycol solvents belonging to groups (a) to (d) above can be used, and even if one type is used, two or more types can be mixed. It may also be used as

(a and b) The weight ratio of the above essential components (a) and (b) must be in the range of 6/1 to 1/6.

If the ratio of component (a) is smaller than this, the cleaning power will be poor, and if the ratio of component (a) is larger than this, there is a risk that the adhesive of the flooring material will be damaged and the flooring material will warp or peel.

Other optional ingredients The floor cleaning agent of the present invention may contain optional ingredients such as a surfactant, virgoo, a water softener, a dye, and a fragrance in addition to the above-mentioned essential ingredients.

Examples of surfactants include nonionic surfactants such as polyoxyethylene alkyl ether and polyoxyethylene alkyl phenyl ether, and sodium alkylsulfonate.
Examples include 7-ion surfactants such as sodium alkylbenzenesulfonate, sodium α-olefinsulfonate, and sodium alkyldiphenyl ether disulfonate.

Examples of the bilgu include sodium tripolyphosphate, sodium birophosphate, sodium orthophosphate, sodium silicate, and sodium dihydrate.

Ethylenediaminetetraacetic acid can be mentioned as a water softener.

(Manufacturing method and method of use) To manufacture the floor cleaning agent of the present invention, an aqueous solution may be prepared by dissolving the essential components and optional components in water.The concentration of the components may be adjusted as appropriate depending on the degree of dirt. . You may also prepare a concentrated solution in advance, put it in a container, and dilute it with water before use.

When cleaning the floor, the cleaning agent diluted with water as described above may be evenly applied to the floor surface using a mop or the like according to a conventional method, and then brushed with a polylasher.

The floor cleaning agent of the present invention is particularly effective when used for cleaning floors coated with urethane resin wax, but it can also be used for cleaning floors coated with other resin waxes. can.
