The invention discloses a chemical grouting material suitable for a humid environment and a preparation method of the chemical grouting material, and belongs to the technical field of grouting plugging materials. The chemical grouting material is prepared from a component A and a component B, wherein the component A is prepared from 60 to 100 parts of epoxy resin, 20 to 40 parts of toughened modified epoxy resin and 10 to 30 parts of N-(glycidyl)-N-phenyl-ethylene oxide methylamine; the component B is prepared from the following components in parts by weight: 20 to 40 parts of ketimine curing agent, 1 to 5 parts of 2, 4, 6-tri (dimethylaminomethyl) phenol, 5 to 10 parts of nano cellulose microcrystal, 5 to 12 parts of magnesium acrylate, 0.5 to 2 parts of coupling agent, 1 to 3 parts of defoaming agent and 1 to 2.5 parts of flatting agent. The epoxy resin and the toughened epoxy resin are mixed to serve as main components of the chemical grouting material, the toughness of the epoxy resin is improved by tough
