The application relates to the technical field of filter materials, and discloses a preparation method of a multilayer interval type continuous gradient structure liquid filter material, and provides the preparation method of the multilayer interval type continuous gradient structure liquid filter material. In the method, the fibers of the dust-containing layer adopt a skin-core structure with PP resin as a core layer and PE resin as a skin layer. The method uses cross-laying, puncture hot baking and multi-roller stretching to composite the filter monomers made of the dust-containing layer into the multilayer interval type continuous gradient structure liquid filter material. In the puncture hot baking, the fibers of the dust-containing layer of the filter monomers can enter the dust-containing layer of the adjacent filter monomers to form fiber entanglement points. The hot baking can make the PE resin of the skin layer melt and form a bonding reinforced fiber entanglement point at the fiber entanglement point, so that the composite strength of the material is significantly increased. The cross-laying and the multi-roller stretching can flatten the puncture holes caused by the puncture to improve the flatness of the surface of the material and ensure that the material will not be significantly deformed.
