Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning liquid for removing dirt components applied to a dirt surface, by effectively making the cleaning liquid hard to flow down and drip, and to prevent drying. The present invention relates to a stain remover capable of removing stains, facilitating the removal of stains and increasing the efficiency.

[0002]

2. Description of the Related Art Generally, various cleaning agents (various acids and alkali solutions) are commercially available for removing stains on concrete surfaces and painted surfaces. All of these are used after dilution with water at the time of use.

[0003] In the actual dirt removal operation, these cleaning liquids are applied to the contaminated surface with a brush or sponge, then wiped off with a rag (rag cloth), and then further washed with water. A method of rubbing off the dirt on the dirty surface with a sponge and then further washing with water is employed.

[0004]

However, in any of the above methods, it is difficult to effectively remove dirt when working on a vertical surface or a downward surface such as a building wall or ceiling. was there.

[0005] That is, of the above-mentioned methods, in the former method in which a cleaning liquid is applied to a contaminated surface with a brush or the like, the cleaning liquid immediately flows down along a vertical surface, or sags on a downward surface. And the contact time between the cleaning liquid and the dirt is very short, so that the dirt component and the cleaning liquid cannot be sufficiently reacted with each other, which is not very efficient.

In the latter method of rubbing off dirt with a rag or sponge containing a cleaning liquid, if too much cleaning liquid is contained, most of the rinsing liquid is immediately applied when the rag is rubbed against a dirty surface. In the same manner as the former method, dirt cannot be efficiently removed as in the case of the former method.

[0007] For this reason, the dirt cannot be sufficiently removed unless the dirt at the same location is used many times by using the cleaning liquid little by little, and the dirt cannot be sufficiently removed. Required a lot of trouble.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and makes it possible to effectively remove stains by maintaining a long contact time between the cleaning solution and the stains, thereby facilitating the stain removal operation. Another object of the present invention is to provide a stain removing agent that can be made highly efficient.

[0009]

The stain remover of the present invention comprises:
It is characterized by being prepared by blending a cleaning agent for removing a dirt component applied to a dirt surface with a resin agent for increasing the viscosity and maintaining a wet state.

According to the present invention, even when the dirty surface is, for example, a vertical surface, it is difficult for the cleaning liquid to flow down and drip, and it is difficult to dry, and the contact time with the dirty portion is maintained for a long time. The chemical reaction between the dirt component and the cleaning liquid can be continued for a long time, or the permeation of the cleaning liquid into the contaminated portion can be maintained for a long time, thereby effectively removing the dirt. And the dirt removal work can be made easier and more efficient,
The labor involved in this work can be reduced.

When a surfactant is further added to the stain remover of the above-mentioned composition, it is possible to improve the permeability of the stain remover to the stain portion.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail. In the present embodiment, a water-soluble resin such as polyethylene glycol resin (for example, having an average molecular weight of about 3300) is used as a thickener for making the cleaning liquid hard to flow down and to prevent dripping, and as a water retention agent for making it difficult to dry. PEG).
Examples of similar water-soluble resins include sodium alginate, carboxymethylcellulose, methylcellulose, polyvinyl alcohol, sodium polyacrylate, and polyethylene oxide. This is mixed with the cleaning solution so as to have a concentration of several% to 38%.

PEG is blended in cosmetic creams and ointments for wounds, is safe for the human body, and is very stable and does not chemically react with cleaning solutions.

As the blending amount increases, the thickness of the applied liquid film becomes thicker, and the liquid film hardly runs down and sags, and also becomes hard to dry. In order to improve the permeability of the stain remover containing PEG in the cleaning solution to the stained portion and to further remove the stain, a small amount of a surfactant, for example, about 0.3% is incorporated as a penetrant. It is effective to do.

In use, the stain remover of the above composition is applied to the stained portion with a brush or a sponge, and then left for an appropriate time. Next, after wiping with a rag or a sponge, the stain remover is removed with a brush or rag containing water. This operation is repeated depending on how the dirt comes off.

In the stain remover of the present embodiment, PEG is added as a thickener for making the washing liquid hard to flow down and to prevent dripping and a water retaining agent for making it difficult to dry. The action of the PEG allows the cleaning liquid to stay on the soiled surface in a long and wet state, and the action of the cleaning liquid on the soil can be maintained for a long time, so that the dirt can be easily and efficiently removed. It can be carried out. In particular, in the dirt removal work on the vertical surface, it is possible to prevent the cleaning liquid from immediately flowing down, and it is possible to prevent the cleaning liquid from dripping on the downward surface such as a ceiling surface. The contact time can be maintained long, and the chemical reaction between the soil component and the cleaning solution can be continued for a long time, or the permeation of the cleaning solution into the soiled portion can be maintained for a long time.

For example, when the concentration of hydrochloric acid is set to 1 to 3% 38
The soil removal agent with a concentration of% PEG is effective for removing the Efro on the surface of the PC plate installed as a driving form during the construction work of a river weir and the iron rust generated on the GRC surface of a certain warehouse ceiling during construction work. there were.

Incidentally, even when a cleaning solution containing only a 1 to 3% hydrochloric acid aqueous solution was applied to these stain-producing portions, the cleaning solution immediately flowed down or dropped on the worker's head.

On the other hand, it is considered that the dirt remover thus prepared can be used not only for the above-mentioned dirt removal but also for the removal of rust on the steel material surface. In this case, when an acid is used as the cleaning solution, a neutralization treatment and a water washing are required after the rust removing operation.

[0020]

In summary, according to the stain remover according to the present invention, a resin agent for increasing the viscosity and maintaining a wet state is added to a cleaning liquid applied to a stained surface to remove stain components. Since the cleaning liquid is hard to flow down and drip even if the dirty surface is, for example, a vertical surface, it is difficult to dry, and the contact time with the dirty portion can be maintained for a long time. The chemical reaction between the dirt component and the cleaning liquid can be continued for a long time, or the permeation of the cleaning liquid into the contaminated part can be maintained for a long time, so that the dirt can be effectively removed and the dirt removal work can be performed. Can be made easier and more efficient, and the labor involved in this work can be reduced.

Further, by blending a surfactant into the stain remover having the above composition, the permeability of the stain remover to the stain portion can be improved.
