The invention discloses a preparation method and application of a sealing material for a concrete impermeability test, and relates to the technical field of sealing material preparation, in particular to the preparation method and application of the sealing material for the concrete impermeability test, the sealing material is metered according to the mass ratio of 100%, the expansion high polymer material accounts for 20%-40%, the non-woven fabric accounts for 15%-20%, and the non-woven fabric accounts for 15%-20%; the resin adhesive accounts for 2%-5%, the hydrophilic fiber paper accounts for 20%-30%, and the thickening agent accounts for 10%-20%. The sealing material for the concrete impermeability test can fully fill and connect a joint between the side face of a concrete impermeability test block and a steel mold into a whole, water permeation is effectively prevented, so that the sealing effect is achieved, and the effective sealing rate reaches 96% or above through verification of multiple tests.
