Description

[Detailed Description of the Invention] The present invention relates to improvements in water supply and drainage pipes for sanitary equipment, such as cleaning pipes for supplying water from a tank to a toilet bowl, or drain pipes for wash basins.

In general, water supply and drainage pipes for sanitary facilities such as those mentioned above are made of metal pipes with a plated surface to maintain their aesthetic appearance, but since they are used for long periods of time in an exposed state, In the case of cleaning pipes, they corrode due to ammonia gas, and in the case of drain pipes, they corrode due to moisture, etc., which impairs the aesthetic appearance and causes water leakage.

The present invention is intended to eliminate such conventional drawbacks, and is characterized by forming a pipe material whose plated surface is further coated with a corrosion inhibitor to provide a coating layer.

Corrosion inhibitors suitable for the purpose of the present invention include those based on synthetic resins such as vinyl, phenol, alkaline, carbonate, aminoalkyd, urethane, acrylic, epoxy, and silicone. Preferably, a coating layer using an epoxy resin as the main material has excellent properties such as good adhesion, strength even after shrinkage, and good water resistance, alkali resistance, and weather resistance. can be formed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the cross-sectional structure of a tube material according to the present invention. Reference numeral 1 indicates a metal tube body formed to a required thickness, a plating layer 2 is provided on the surface of the metal tube body, and a plating layer 2 is provided on the upper surface of the plating layer 2. A coating layer 3 for preventing corrosion is formed by coating with a corrosion inhibitor mainly composed of a synthetic resin or the like.

2 to 4 show examples of the use of the tube material according to the present invention.

That is, the one shown in Fig. 2 is formed in the washing pipe a of the high tank type, the one shown in Fig. 3 is formed in the washing pipe a of the low tank type, and the one shown in Fig. 4 is formed in the washing pipe a of the low tank type. It is formed in the drain pipe C of.

The water supply and drainage pipe for sanitary equipment of the present invention formed in this way prevents corrosion caused by ammonia gas or moisture by coating the surface with a corrosion inhibitor, thereby preventing accidents such as water leakage over a long period of time. It can be used stably without causing any problems.

In addition, when a synthetic resin such as an aminoalkyd, urethane, or acrylic resin is used as the main ingredient in the corrosion inhibitor, the coating layer can be formed transparent, so that the beauty of the plating layer can be expressed as is. and can be maintained as is.

Furthermore, if desired, it is also possible to form a coating layer colored in an arbitrary color by mixing a pigment or the like into the corrosion inhibitor.

As mentioned above, the water supply and drainage pipe for sanitary equipment of the present invention is protected from corrosion by coating the surface with a coating layer formed with a corrosion inhibitor, and can prevent water leakage caused by corrosion. It can be used stably for a long period of time without causing any of the above problems, and furthermore, it can maintain extremely desirable characteristics in terms of maintaining the aesthetic appearance desired for sanitary equipment.
