The invention provides a backing film material for solar cells and a preparation method thereof. The backing film material is prepared from polyvinylidene fluoride, polymethyl methacrylate, amide poly-hexylideneadipate, barite powder, dioctyl phthalate, epoxy vegetable oil, acetate starch, polylactic acid, vinyl olefin copolymer, zinc stearate, nano silicon powder, azodiisobutyronitrile, 2,3-epoxy propyl-trimethyl ammonium chloride, a solubilizer, a pore-forming agent and a solvent. The preparation method comprises the following steps: adding the components into a stirrer, uniformly mixing, adding the mixture into a reaction kettle, heating and stirring to react, carrying out vacuum dehydration on the film preparation solution at 90-100 DEG C, finally, sending the film preparation particles into a double screw extruder, and carrying out extrusion, running and film formation. The backing film material has the advantages of excellent mechanical properties, favorable weather resistance, favorable vapor barrier effect, favorable hydrophobicity and favorable bonding property, and satisfies the requirements for various main properties of the solar cell backing film.
