The invention relates to the technical field of a refractory material, in particular to a sol-bonded refractory repair material and a repair method thereof. In order to overcome the disadvantages that the prior refractory repair material is low in high-temperature bonding strength, slow to solidify, difficult to bake fast, easy to fall off, poor in anti-erosion capability, and so on, and the invention provides the sol-bonded refractory repair material, consisting of a repair material matrix, silicon carbide, silicon oxide or alumina micropowder, sol and promoting coagulant. Compared with the prior art, the refractory repair material can increase the bonding strength of the repair material with a furnace lining of a main channel, a slag groove, a hot metal ladle, a torpedo tank or other place, has good durability, prolongs the service life of the furnace lining, decreases repair time, simultaneously raises the anti-erosion capability of the furnace lining, and reduces the refractory material consumption of iron systems.
