PURPOSE : A manufacturing method of a water proof coating agent for a submarine tunnel and a deep tunnel is provided to be able to manufacture a water proof coating agent capable of purifying the air inside the tunnel while permanently producing the weak current of 0.06 mA which is useful to the human body.CONSTITUTION : A manufacturing method of a water proof coating agent releasing anions for a submarine tunnel and a deep tunnel in 40-60 m down in underground comprises a step of mixing monazite, which is a rare earth noble metal, with red clay, and reacting the mixture with a coagulant. The coagulant is selected from ethylene vinyl acetate, polyvinyl acetate, solvent-free epoxy and latex. The manufactured water proof coating agent is able to release a large amount of anions when applied on the inner wall and/or the ceiling of the tunnel with a spray coating method.COPYRIGHT KIPO 2013 |
