SOLUTION: A material which thickens condensed water produced by dew condensation on glass, a mirror, a metal or the like to prevent the condensed water from running down is incorporated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a window glass room interior, a mirror,
The present invention relates to a dew-prevention glass coating agent that prevents dew condensation water from flowing when metal or the like becomes cloudy due to dew condensation or grows until condensation progresses and dew condensation water flows.

[0002]

2. Description of the Related Art As a conventional anti-dripping agent for dew condensation water, a hydrophilic substance such as a surfactant or a hydrophilic resin is used, such as glass,
By applying to a metal or the like, the surface is subjected to a hydrophilic treatment to suppress the occurrence of fogging and prevent the occurrence of dew condensation.

[0003]

In the rainy season and during the winter season, condensed water that has condensed flows down into the window glass room, and window glass that cannot be drained to the outside flows into the room and molds on walls, folds, etc. generate. In order to prevent this dew condensation, a surfactant, hydrophilic resin, etc. is applied and adhered to glass, mirrors, etc. as a conventional anti-dripping agent for dewed water droplets, and the surface is subjected to a hydrophilic treatment to prevent fogging. Although the occurrence of dew condensation was prevented, more dew condensation (condensed) water was generated, and the problem that the condensed water dripped and flowed occurred.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to glass,
A dew-dropping agent for preventing condensation of water droplets formed on mirrors, metals, and the like, characterized in that it contains a thickening substance, and the thickening substance is a water-soluble polymer. The above problem was solved by using a saccharide or an alkyl acid soda, a carboxyvinyl polymer, a polyethylene oxide, aluminum magnesium silicate, bentonite, and a cellulose derivative, and further characterized by being solubilized in water.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The anti-condensation glass coating agent according to the present invention comprises a glass, a mirror,
By coating and drying on metal, etc., the thickening substance adheres to glass, mirror, metal, etc., and thereby, glass, mirror,
Water droplets condensed on metal or the like are thickened and made difficult to flow, thereby preventing the water droplets from flowing and flowing.

[0006] In particular, in the present invention, thickening of water droplets and
The problem was solved in consideration of whitening and unevenness of the surface of glass, mirror, metal, etc. after coating and drying.

In this case, as a thickener substance to be applied on a surface such as glass, water-soluble polysaccharides include xanthan gum, gellan gum, guar gum or a derivative thereof.
And the like, and as the cellulose derivative, carboxymethylcellulose, hydroxyethylcellulose, hydroxymethylpropylcellulose, hydroxypropylcellulose, ethylcellulose, etc. can be raised. Examples include sodium alkyl acid, carboxyvinyl polymer, polyethylene oxide, aluminum magnesium silicate, bentonite, and the like.

[0008] More specifically, as a thickener with little whitening and rum after coating and drying on a glass, mirror or metal surface,
In the water-soluble high molecular polysaccharide, xanthan gum is raised,
Hydroxyethyl cellulose is preferred as the cellulose derivative. These can be used alone or in combination.

As already mentioned, the thickeners can be used alone or in admixture. Further, when these are mixed with water, alcohols and surfactants (anionic, nonionic, amphoteric) as required, the effect is remarkable.

Here, the dew condensation preventing glass coating agent can be applied and dried with a cloth, sponge, tissue, or the like, or filled in a can with a liquefied gas and applied by an aerosol method.

In this case, when a thickening substance is used as an agent for preventing the flow of dewed water, the upper limit of the concentration is 30% by weight or less, preferably 20% by weight or less, more preferably 1% by weight or less.
0% by weight or less, more preferably 5% by weight or less, most preferably 1% by weight or less. The upper limit of the concentration of the thickening substance is determined as described above, because if the concentration is too high, the viscosity may be too high and coating may be difficult.

[0012]

The present invention will be described in more detail with reference to the following examples.

Examples are shown in Examples 1 to 5 and Comparative Examples 1 to 3. These components are as shown below. Example 1, xanthan gum weight 0.5%, water weight 99.

6% Comparative Example 3, untreated

Examples 1 to 5 (the anti-condensation glass coating agent of the present invention) and Comparative Examples 1 to 3 were applied to a cleanly cleaned glass container having a diameter of 5 cm and a height of 7.5 cm, and dried at room temperature for 24 hours. Put ice and water in a vessel with a diameter of 8 cm and a height of 3 cm, and in a room adjusted to a room temperature of 23 degrees Celsius and a humidity of 50 to 60%, every 10 minutes, all generated dew (condensed) water and dew water The amount of dripping is measured and evaluated for one hour.

Next, Examples 1 to 5 (the anti-condensation glass coating agent of the present invention) are applied to the glass surface which has been thoroughly washed and dried.
And Comparative Examples 1 to 3 were applied, and the glass surface after drying at room temperature for 24 hours was checked for whitening and unevenness.

The results are shown in Tables 1 and 2.

[0017]

[Table 1]

[0018]

[Table 2]

The following can be said as the results shown in Tables 1 and 2. As is clear from Examples 1 to 5 and Comparative Examples 1 to 3, the glass coated with the anti-condensation glass coating agent makes the dew (condensed) water thicker to prevent dripping and flowing.

On the other hand, it is shown that the effect of retaining dew (condensed) water is improved by increasing the amount of the thickener attached compared to Examples 3 and 4.

[0021]

According to the present invention, the following effects can be obtained. By applying an aqueous solution containing a thickener to glass and then drying the solution, the condensation formed on the glass is thickened, thereby making it possible to prevent the condensation from flowing and flowing.
