The invention relates to a novel method for preparing a filter press reinforced composite rubber material filter plate with pressure resistance, corrosion resistance and excellent sealing property. The preparation method comprises the following steps: performing activated coating treatment on graphite powder and fiber surfaces, mixing the graphite powder and fibers subjected to surface treatment at a high speed so as to obtain a graphite mixture, adding the mixture into a water-based surface treatment solvent, dispersing and mixing, adding a natural rubber adhesive for stirring and liquid removing, performing vacuum drying, and the coating the fibers for later use; mixing, namely respectively mixing the rubber, uniformly mixing, sequentially adding the fibers subjected to surface treatment, a scorch retarder, an accelerant and other small materials, graphite, carbon black, processing aids and a vulcanizing agent for mixing, and performing thin-passing pulling on the uniformly mixed rubber for later use; and p
