RAPIDLY CURABLE COATING-TYPE REINFORCING MATERIAL FOR STEEL PLATE, AND METHOD FOR REINFORCING STEEL PLATE

摘要

PROBLEM TO BE SOLVED: To provide a strong coating-type reinforcing material for a steel plate hardly dropped at a hot-water washing step and a transforming step.;SOLUTION: This coating-type reinforcing material for the steel plate requires 60-85% gel fraction in a cured product after the lapse of 30 min to 1 hr after coating a mixture obtained by mixing a main material with a curing agent and heated to 30-50°C, or 50-70 hardness of the cured film, measured by a C-type tester provided by JIS K6301 after the lapse of 30 min to 1 hr after coating the mixture heated to 30-50°C. The above condition for the heated and coated reinforcing material after the lapse of 30 min to 1 hr after the coating is required for providing the coated film which is sufficiently cured and can resist to the water current and shower in a hot water washing step. Optionally, the coating-type reinforcing material for the steel plate having the required properties is obtained by adding an epoxy-reactive diluent, a filler or the like.;COPYRIGHT: (C)2003,JPO
