Description

[Detailed description of the invention] Industrial applications The present invention relates to a cleaning agent for removing floor cleaning agents.

More specifically, the present invention relates to a cleaning agent for completely removing polish from a floor surface coated with a synthetic resin polish.

BACKGROUND OF THE INVENTION Polishing agents containing synthetic resin as a soothing ingredient (hereinafter referred to as resin wax) are frequently used as polishing agents for the floors of buildings.

Immediately after applying resin wax, the floor surface has a beautiful shiny appearance, but as an hour passes, scratches and dirt from walking adhere to the resin wax film, spoiling its appearance. Clean it from time to time, and then apply resin wax to repair it. This surface cleaning is carried out to remove the surface layer of the resin wax film along with dirt. Normally, this surface cleaning and repair application is performed once or twice a month, and is continued for a year or two. During this period, dirt that was not completely removed during each surface cleaning builds up.
Eventually, even if you keep repeating this process, you will not be able to obtain a satisfactory aesthetic appearance.

At that point, remove the resin wax completely and reapply new resin wax.

The work to completely remove resin wax from the floor is as follows:
After applying a cleaning agent for removal on the resin wax film,
This is done using a poly lasher with a floor pad attached. The cleaning agent used at that time is a surfactant (
nonionic surfactants such as polyoxyethylene alkyl ether and polyoxyethylene alkyl phenyl ether, and anionic surfactants such as sodium alkyl sulfonate, sodium alkylbenzene sulfonate, sodium α-olefin sulfonate, sodium alkyldiphenyl ether disulfonate), Alkaline agents (potassium hydroxide, sodium hydroxide, sodium silicate, ammonia, monoethanolamine l and ethylene glycol solvents (ethylene glycol monobutyl ether).

A composition prepared by appropriately mixing ethylene glycol monoethyl ether, etc. and dissolving it in water is used.

When a conventional resin wax whose main component is acrylic synthetic resin (hereinafter referred to as acrylic resin wax) was used as the resin wax, the removal work could be carried out smoothly by using the above-mentioned cleaning agent. was.

However, in recent years, in response to the demand for labor-saving floor cleaning,
As resin waxes containing urethane-based synthetic resins have come to be used, problems have arisen regarding their removal. The circumstances will be explained below.

Urethane resin wax contains a urethane synthetic resin that has a three-dimensional network molecular structure created by covalent bonds, so it has a stronger film and is more durable than acrylic resin wax. . Therefore, when this resin wax is used, the interval between surface cleaning and repair application becomes longer, and the labor required for floor cleaning can be reduced accordingly.

For the above reasons, urethane resin waxes have become preferred for use on shopping floors and terminal building floors. The cleaning of floors in such places needs to be completed within a certain short period of time, but the conventional cleaning agent for removing acrylic resin wax mentioned above can be replaced with urethane resin wax. Even if applied, it cannot be removed within a short time.

Prior Art Therefore, in order to facilitate the removal of urethane resin wax, for example, a conventional cleaning agent to which about 5% by weight of dioxane or tetrahydrofuran is added, or a mixture containing N-methyl-2-pyrrolidone as a main component, is used. Attempts were made to create a paint remover, but it could not be put to practical use because it would dissolve vinyl chloride flooring materials, which are often used as flooring materials, and the adhesive that fixes the flooring materials to the floor surface.

In addition, by adding about 5% of cyclic amines such as cyclohexylamine and dicyclohexylamine to conventional cleaning agents for removal, a cleaning agent with high removal performance for urethane resin waxes was obtained, but it contained bromine and skin irritation. It could not be put into practical use because it had a strong impact on workers.

Problems to be solved by the invention Since the current situation is as described above, the following performance (1) or 3)
It is an object of the present invention to provide a cleaning agent for removing urethane resin wax that satisfies all of the following.

(1) Excellent removal ability (2) Safe to use with no unpleasant odor (3) No effect on flooring Means to solve the problem One bottle to achieve the above purpose As a result of intensive research, the inventors found that a composition prepared by dissolving a specific amount of 2 to 6 moles of ethylene oxide adduct of cyclohexylamine and a specific amount of a specific glycol solvent in water was effective in removing urethane resin wax. The present invention was completed based on the discovery that all of the above-mentioned required performances as a cleaning agent for use in cleaning products are satisfied.

That is, the present invention provides (a) an ethylene oxide adduct of cyclohexylamine obtained by reacting 2 to 6 moles of ethylene oxide with 1 mole of cyclohexylamine in an amount of 4 to 8 moles of the total amount of the composition.
A cleaning agent for removing floor polish, characterized in that it is an aqueous solution containing 2 to 6% by weight of (b) propylene glycol monomethyl ether and/or 3-methyl-3-methoxybutanol based on the total amount of the composition. be.

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

(Components) (a) Ethylene oxide/adduct 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 the number of moles is less than 2 moles, it is inappropriate because it has a strong unpleasant odor and cannot be used continuously for a long time. When the number of moles added exceeds 6 moles, the dissolving power for urethane resin wax becomes small, resulting in a decrease in wax removal performance.

The ratio of component (a) in the composition is 4% by weight of the total amount of M acid.
to 8% by weight. If it is less than 4% by weight, the removal performance for urethane resin wax is insufficient;
Exceeding this is uneconomical because the removal performance does not improve.

(b) Propylene glycol monomethyl ether As pentapropylene glycol monomethyl ether and 3-methyl-3-methoxybutanol, commercially available products can be used. Ethylene glycol monoethyl ether and ethylene glycol monobutyl ether are effective as glycol solvents, which may be used either alone or as a mixture of the two. However, since these are highly toxic and have a strong odor, if a cleaning agent containing them is used on a poorly ventilated floor, it will have an impact on cleaning workers, so they have been excluded from the present invention.

The proportion of component (b) in the composition is 2% to 6% by weight of the total amount of the composition. If it is less than 2% by weight, the removal performance for urethane resin wax is insufficient, and if it exceeds 6% by weight, the removal performance will not improve, which is uneconomical.

In addition to the above-mentioned essential ingredients, the cleaning agent for removing floor polish of the present invention contains optional ingredients such as surfactants, alkaline agents, and solubilizers that have been used in conventional cleaning agents for removal. It can contain agents, water softeners, dyes, fragrances, antifoaming agents, etc.

Examples of surfactants include nonionic surfactants such as polyoxyethylene alkyl ether and polyoxyethylene alkylphenyl ether, and sodium alkylsulfonate, sodium alkylbenzenesulfonate, sodium α-olefin sulfonate, and sodium alkyldiphenyl ether disulfonate. 7-ionic surfactants may be mentioned.

As alkaline agents, potassium hydroxide, sodium hydroxide, potassium carbonate, sodium carbonate, sodium silicate,
Monoethanolamine and the like can be mentioned.

As a solubilizer, sodium para-toluenesulfonate,
Mention may be made of formalin condensates of sodium naphthalenesulfonate.

Examples of water softeners include sodium ethylenediaminetetraacetate.

(Manufacturing method and usage method) In order to manufacture the cleaning agent for removing floor polish of the present invention, an aqueous solution may be prepared by dissolving essential components and optional components in water.

In order to remove the resin wax, a cleaning agent for removal may be applied evenly onto the resin wax film using a mop or the like in a conventional manner, and then the resin wax may be cleaned using a polylasher equipped with a floor pad.

The cleaning agent for removing floor polish of the present invention is particularly effective when used to remove urethane resin waxes, but it can also be used to remove other resin waxes. can.
