Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing scale from adhering to a wash basin equipped with a wash basin and a water discharge device, and a wash basin capable of performing the method. Further, the present invention relates to a coating composition for preventing scale from adhering to a wash basin in a wash basin and making the wash basin hard to be stained.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for sanitary spaces to be clean, and it has been widely desired to keep the basin surface sanitarily clean. As a method of keeping the basin surface sanitary clean in general households since ancient times, surfactants,
A method has been adopted in which a detergent such as a weak acid or a weak alkaline agent is attached to a scourer or brush to strongly rub the ceramic surface, and both chemical removal with the detergent and physical removal by scrubbing with a scrub brush are used. .

[0003]

Heretofore, as one form of basin dirt, there is dirt due to water drops dripping from a spout of a water discharge device. This scale tends to adhere to a fixed area, and this scale can be sufficiently removed by a method of rubbing the surface of a ceramic with a detergent such as the above-described surfactant, weak acid, or weak alkali onto a scourer or a brush. Could not be removed. In view of the above, an object of the present invention is to provide a washroom facility in which the water stain is less likely to occur. It is another object of the present invention to provide a coating composition for a wash basin having a water discharging device that makes it difficult for the basin stain to occur. Still another object of the present invention is to provide a method for using the coating composition to make the above-mentioned scale less likely to occur on the surface of a washbasin.

[0004]

SUMMARY OF THE INVENTION Water droplets dripping from a water discharge device flow through a fixed place. When observing the surface of the basin used for a long period of time, the remaining water is intermittently supplied in that part, the gloss of the pottery surface is lost, and this part consists of a thin film mainly composed of silica. It was found that scale was formed. Furthermore, the surface to which the scale was attached had a large surface roughness, so that the stain was easily attached, and the surface state was such that microorganisms such as molds could easily propagate. From the above observations, it is estimated that the adhesion of scale is one of the stains on the surface of the pottery used for a long period of time, and the mechanism of the generation is as follows. (1) The remaining water after the water discharge continues to droop from the water discharge port intermittently for a long time, and flows on the surface of the basin immediately below the water discharge port, or flows along the water discharge device to a portion where the water discharge device is fixed. As a result, the residual water stays on the surface of the basin immediately below the water outlet or the surface of the basin to which the water discharge device is fixed and / or the surface of the fixed portion of the peripheral member and / or its surroundings (the direction in which the residual water drips and the retained water The stagnation point is almost the same every time.) (2) The retained water is dried at that location to form a film of scale (a film made of an inorganic substance such as SiO2 or CaO, which is a mineral component contained in the water, is formed. Rubbing does not completely remove it). Therefore, in order to prevent the occurrence of water stains, it is considered to be a good method to prevent the residual water dripping from the spout from flowing in the same place, and to drain the water quickly without stagnating.

[0005] In the present invention, based on the above observation and consideration of the mechanism, in a washbasin equipped with a washbasin and a water discharge device having a spout, residual water after spouting does not flow through the same part of the surface of the washbasin. A method for preventing scale from adhering to the basin surface in the basin equipment, and a residual water after water discharge in the basin equipment equipped with a basin and a water discharge device having a water outlet. A means for quickly draining or stopping water is provided.

[0006] In a preferred embodiment of the present invention, in order to prevent the above-mentioned water stains, the flowing water portion and / or its periphery at the time of a minute amount of water discharge on the surface of the basin; A method for preventing scale from adhering to a wash basin in a wash basin, comprising forming a water-repellent coating and / or a water-slidable coating on a fixed portion of the water discharging device and / or the periphery thereof, and a method for discharging a small amount of water on the surface of the wash basin. A water-repellent film and / or a water-sliding film is formed on a portion where the water-discharge device is fixed and / or its periphery in a basin or its peripheral member to which the water-discharge device is fixed. The present invention provides a scale facility for preventing scale adhesion. At the portion where the water-repellent and water-slidable film is formed, water flows down without stagnation. Therefore, the flushing part and / or its periphery at the time of minute water discharge on the surface of the basin, and the fixed part of the basin or the peripheral member of the basin or the peripheral member to which the basin or the peripheral member to which the residual water flows along the basin, and By forming the water-repellent coating and / or the water-sliding coating on the periphery thereof, the residual water does not continuously flow in the same portion, and is less likely to stay. Therefore, the basin is less likely to be stained with water.

[0007] In the present invention, a room-temperature-curable silicone, or a room-temperature-curable fluororesin, or a mixture of a fluorine-containing resin and a room-temperature-curable silicone, characterized in that a small amount of water is discharged from the basin surface at the time of minute water discharge. A part and / or its periphery; or a washbasin for forming a water-repellent coating and / or a water-sliding coating on a fixed part of the water-discharge device and / or its periphery in a washbasin or a peripheral member to which the water-discharge device is fixed. A facility coating composition and the above coating composition, and a flow area at the time of minute water discharge on the surface of the wash basin and / or the periphery thereof; or, a fixed portion of the water discharge apparatus in a wash basin or a peripheral member to which the water discharge apparatus is fixed, and And / or a method of preventing scale from adhering to a basin surface, including a step of applying the composition to the periphery thereof, and a step of curing the coating composition. Providing antifouling methods basin surface in. By coating the hardening component with a room temperature hardening substance, it becomes possible to make it difficult for water scale to generate stains even on the existing basin surface.
