The present application relates to the technical field of plastic film, in particular to a high-strength biodegradable composite film and a preparation method thereof.The present application overcomes the shortcomings of poor strength and poor barrier property of the existing film.The present application feeds a mixture of polylactic acid, modified montmorillonite, modified polycaprolactone and stearic acid amide into a double-screw extruder;then step-by-step blends the mixture A and 1,4-butanediol diglycidyl ether;finally, the material is extruded, cooled and granulated to obtain a composite material;the composite material is blown into a film to obtain the composite film;wherein the mixture A comprises polybutylene adipate terephthalate, modified mesoporous nanosilica, zinc laurate and 2-phenylimidazoline;the modified polycaprolactone is prepared from the polycaprolactone, maleic anhydride and dicumyl peroxide.The film prepared by the present application has high strength and good barrier property.
