REINFORCING MEMBER COATED WITH HIGH ADHESION CORROSION-PROOF COAT, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing member coated with a high adhesion corrosion-proof coat enhanced in adhesion to concrete by forming firm protrusions in a state of being coated with epoxy resin, on a second layer corrosion-proof coat while solving a problem of pinholes inevitably formed in the corrosion-proof coat by forming two upper and lower layers of corrosion-proof coats on the surface of the reinforcing member by spraying an epoxy powder paint in a temperature condition where the performance of epoxy resin can be maintained. SOLUTION: The reinforcing member coated with the high adhesion corrosion-proof coat having countless protrusions 3a on the surface of the second corrosion-proof coat 3 is manufactured by heating the reinforcing member 1, forming the first corrosion-proof coat 2 by spraying the epoxy powder paint 4 to the reinforcing member while the surface temperature of the reinforcing member is 200-250°C, and in this temperature condition, forming the second corrosion-proof coat 3 by spraying the epoxy powder paint 4 mixed with acrylic resin beads (b) with the grain size of 2.5-3 times as large as the grain size of epoxy resin powder (a), to the surface of the first corrosion-proof coat in a molten state.
