(57) [Summary] [PROBLEMS] To form a joint having excellent mechanical properties, maintaining sufficient fluidity and curability even at a low temperature, can be used in winter in cold regions, and has almost no backlash. The present invention provides a curable resin composition for a threaded joint of a steel rod used for: SOLUTION: 100 parts by mass of a polymerizable vinyl monomer comprising methyl methacrylate, 2-hydroxyethyl methacrylate and 2,2-bis (4- (methacryloxyethoxy) phenyl) propane, and a polymerization initiator 1 comprising cumene hydroperoxide. 10 parts by mass, a polymerization accelerator comprising vanadyl acetylacetate 0.1 to 0.1 1.0 parts by mass, the total amount of acrylonitrile-butadiene rubber and methyl methacrylate-butadiene-styrene copolymer is 10 to 30 parts by mass, and the average particle size is 10 A curable resin composition containing 100 to 300 parts by mass of silica powder having a particle size of 50 to 50 m. |
