The present invention provides an epoxy resin-based rapid repairing material and the preparation method. The epoxy resin-based rapid repairing material is made of the sand, talcum powder, epoxy resin, polyamide and diluent. The preparation method includes: the epoxy resin and the diluent are mixed well; the polyamide is added and stirred to form the epoxy serum; the sand and talcum powder are mixed well; the epoxy serum and the mixture of the sand and talcum powder are stirred evenly; the acquired epoxy resin-based rapid repairing material can reach the effect of the moderate cost, the early strength (3d can reach 60 MPa), the moderate strength in the later period, the good adhesive connection, the convenient construction, the short construction period and no closure of the traffic; the epoxy resin-based rapid repairing material can be used to repair the concrete buildings such as the bridge, the tunnel, the road, the house and so on.
