    摘要: The present invention provides a reinforcing bar material coated with a high adhesion anticorrosion film that enables to increase adhesion strength to concrete, which comprises forming two layers of anticorrosion films on a surface of a reinforcing bar material by means of spraying an epoxy powder coating material under a temperature condition where performance of the epoxy resin can be retained, so as to solve a pin hole problem that inevitably occurs in an anticorrosion film, and also to exhibit firm projections in a state coated with the epoxy resin on the second layer of anticorrosion film.The present invention comprises heating a reinforcing bar material, spraying and melt-adhering an epoxy powder coating material onto the reinforcing bar material while a temperature on a surface of the reinforcing bar material is between 200 and 250° C. so as to form a first anticorrosion film, and also, under this temperature condition, spraying and melt-adhering an epoxy powder coating material with acrylic resin beads having a particle diameter 2.5 to 3 times that of the epoxy resin powder mixed in on a surface of the first anticorrosion film in a molten state so as to form a second anticorrosion film, followed by cooling the reinforcing bar material coated with the first and second anticorrosion films to prepare the reinforcing bar material coated with a high adhesion anticorrosion film having countless projections formed by the second anticorrosion film.
