The invention relates to the field of coating materials, particularly to a scouring-resistant repair coating material capable of being quickly cured at room temperature. According to the invention, the coating material is a two-component coating material, wherein the first component is composed of an epoxy resin, a scouring-resistant filler and a solvent, the second component is composed of a curing agent and an accelerant, the surface drying time of a coating layer prepared through mixed use is within 30 min, the hard drying time is within 2 h, the stacking time is within 6 h, the normal-temperature curing time is within 3 d, and the hardness of a coating layer swing rod is 0.8 or above. According to the invention, room-temperature rapid curing can be realized, waiting time is reduced, arapid repairing effect is achieved, and the scouring resistance requirement of an original coating is met.
