Maximum grain size with 1mm, the flow calcination petroleum corks grain where the grain grain size 0.13

摘要

PROBLEM TO BE SOLVED: To provide a conductive aqueous coating material to cover a primary anode composed of a metal wire used for an anode material for electric anticorrosion of a reinforced concrete structure, whose coated film is excellent in adhesivity even if the coated film is as thick as 0.5 mm, and whose coated film resistance exhibits only a small over-time change even in a long-term anticorrosive current.;SOLUTION: By selecting an aqueous acrylic resin or an aqueous epoxy resin as an aqueous binder, selecting particle diameters of conductivity-imparting particles of three types of fluidized-firing petroleum coke particles, scaly graphite and conductive carbon black as conductivity-imparting materials, and adjusting the blend amounts of the aqueous binder and the conductivity-imparting materials, a conductive aqueous coating material for electric anticorrosion of reinforced concrete structures used in a long-term outdoor exposure environment can be obtained.;COPYRIGHT: (C)2012,JPO&INPIT
