The invention relates to a modified epoxy mortar abrasion-resistant patching material which comprises a component A and a component B. The mass ratio of the A component and the B component is 4:1. The A component comprises, by weight, 15-20 parts of epoxy resin, 1.5-2 parts of flexibilizer, 1.5-3 parts of reactive diluent and 75-82 parts of abrasive aggregates. The B component comprises, by weight, 18-24 parts of hardening agent, 1-1.5 parts of coupling agent and 75-80 parts of abrasive aggregates. The abrasive aggregates are quartz-sand-class aggregates or diamond-sand-class aggregates. The mass ratio of aggregates with the particle diameter of 10-20 meshes to aggregates with the particle diameter of 20-40 meshes to aggreates with the particel diameter of 40-70 to aggreates with the particel diameter of 100-200 meshes is 0-1 to 1-2 to 0-2 to 0-1. The hardening agent is a polyether amine hardening agent. According to the modified epoxy mortar abrasion-resistant patching material, the abrasion-resistant strength and the anti-impact strength are improved, the hardening reaction speed is lowered and micro cracks in the early stage of epoxy mortar are avoided.
