Zusammenfassung:	The invention relates to the technical field of building covering composite layers, in particular to a multi-layer composite layer material for a building covering layer and a preparation method of the multi-layer composite layer material. A middle clamping film layer is further arranged on the upper portion of the base film base layer, an outer film improvement layer is arranged on the upper portion of the middle clamping film layer, and the outer film improvement layer, the middle clamping film layer and the base film base layer are sequentially arranged from outside to inside. According to the invention, the multi-adjustment bidirectional modifier and the reinforcing agent doped with bentonite for adjustment are added on the basis of the raw materials of the outer film improvement layer and the base film base layer, and the multi-adjustment bidirectional modifier and the reinforcing agent doped with bentonite are coordinated and synergic, so that the mechanical property and the moisture permeability barrie
