The invention discloses a corrosion and high pressure resistant and environment-friendly filtering material and a preparation method thereof. The corrosion and high pressure resistant and environment-friendly filtering material comprises a textile fabric obtained by blending basalt fiber filaments, carbon fiber filaments, aramid fiber filaments and glass fiber filaments, sellaite needled felts needled on the upper surface and the lower surface of the textile fabric and chemical films covering the surfaces of the sellaite needled felts. The surfaces of the basalt nanofiber filaments, the carbon nanofiber filaments and the glass nanofiber filaments are subjected to dipping treatment in a polyurethane solution. The surfaces of the aramid nanofiber filaments are subjected to organic silicon resin dipping treatment. The environment-friendly filtering material is reasonable in structural design and good in filtering performance, has the excellent comprehensive properties such as corrosion resistance, high pressure
