Epoxy resin grouting material and preparation method thereof

The invention relates to the technical field of polymer grouting materials, in particular to an epoxy resin grouting material and a preparation method thereof. The epoxy resin grouting material is prepared from a component A, a component B and a component C, wherein the component A is prepared from the following raw materials in parts by weight: 50 to 80 parts of epoxy resin, 3 to 5 parts of benzyl alcohol, and 8 to 10 parts of diluent; the component B is prepared from the following raw materials in parts by weight: 30 to 40 parts of polyether amine curing agent, 20 to 30 parts of N-aminoethylpiperazine, and 3 to 5 parts of benzyl alcohol; the component C is a cement-based polymer mortar. The epoxy resin grouting material provided by the invention has the advantages that the raw material formula of each component is innovated; especially, the component A uses benzyl alcohol, and the component B uses N-aminoethylpiperazine and benzyl alcohol, so that the raw materials in the componentsare promoted to integrate
