密着一体化した電気防食法である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cathodic protection method for steel pipes, steel materials for building materials, and other metal surfaces. This is a cathodic protection method that closely integrates current-carrying members made of paint, sheets, etc. mixed with current-carrying substances.

いた。Conventional electrolytic corrosion protection methods of this type include the so-called external power source method and galvanic anode method, in which a corrosion protection current corresponding to the prevention of electrolytic corrosion of the metal is applied to prevent electrolytic corrosion. However, in most of these conventional methods, the metal surface is left in a so-called bare state to achieve the purpose, so it is not sufficient to prevent corrosion factors other than electrical causes such as bacteria and moisture. Yes, we were forced to take countermeasures.

とするものである。Therefore, as a result of extensive research, the inventor of the present invention has found that a current-carrying member capable of passing a predetermined anti-corrosion current to a metal surface, such as a current-carrying paint, a current-carrying sheet, a current-carrying tape, etc., allows a constant corrosion-protective current to flow through the metal surface, while at the same time In order to prevent chemical corrosion etc.
It is an object of the present invention to achieve the object of the present invention by providing a current-carrying member, such as a current-carrying paint, with the property of protecting metal from water, oxygen, and other corrosive factors, and by closely integrating it with the metal surface.

性を保持せしめるのである。As for the range of metals that can be used in the present invention, various metals such as steel pipes and steel materials for building materials can be selected as appropriate. First, we will explain the current-carrying paint, which is an example of a current-carrying member. Generally, epoxy resins, urethane resins, alkyd resins, etc. can be used as resins for cathodic protection. Any type of emulsion type may be used,
From the viewpoint of pollution, it is desirable to use an emulsion type. Then, using these resins as a base, an inorganic or organic conductive substance is mixed to maintain conductivity.

る事を条件とする通電テープを用いるのがよい。Next, considering an example in which a current-carrying sheet is used as a current-carrying member, the core material as a constituent element is a sheet impregnated or coated with a fibrous material, for example, and which satisfies the above conditions. Furthermore, when using a current-carrying tape as a current-carrying member, it is necessary to process the tape using a shrinkable resin with a current-carrying adhesive and to mix an organic or inorganic current-carrying substance into the resin. It is best to use electrically conductive tape with the following conditions.

である。By closely integrating a current-carrying member having such conditions with various metal surfaces, it is possible to not only prevent electrolytic corrosion as intended by the prior art, which is the object of the present invention, but also to prevent attack by corrosion factors other than electrical factors. It is also fully effective against.
