The invention provides SCR denitration catalyst end face hardening hydrosol and a preparation method therefor. The SCR denitration catalyst end face hardening hydrosol comprises the following components: an aluminum sulfate solution with a concentration of 20%-27%, an oxalic acid solution with a concentration of 25%-50% and an ammonium metavanadate solution with a concentration of 33%-66%, wherein, the weight part ratio of the oxalic acid solution to the ammonium metavanadate solution is (0.6-1):1, the oxalic acid solution and the ammonium metavanadate solution are mixed and a mixed solution is prepared, the weight part ratio of the aluminum sulfate solution, the mixed solution and polyvinyl alcohol is 1:(0.1-0.2):0.02. SCR denitration catalysts can be immersed in the SCR denitration catalyst end face hardening hydrosol, thus the load capacity of the SCR denitration catalysts is raised and the service life of the SCR denitration catalysts is prolonged.
