The invention discloses a rail vehicle dirt box which comprises an upper box body and a bottom plate, the upper box body and the bottom plate are each of a foam sandwich structure, the upper box body is arranged on the bottom plate in an adhesive mode, the foam sandwich structure comprises a core layer, an inner skin layer and an outer skin layer, and the inner skin layer and the outer skin layer are arranged on the inner side and the outer side of the core layer in an adhesive mode through adhesive film layers. The core layer comprises a framework and a foam layer, and the foam layer is arranged in a space defined by the framework and the adhesive film layer. The invention further provides a preparation method of the rail vehicle dirt box. The main materials of the upper box body and the bottom plate of the dirt box for the railway vehicle are foam sandwich structures with built-in frameworks, the dirt box has the characteristics of light weight and high strength, the dead weight is light, the strength meets the requirement, and the overall rigidity is larger than that of a stainless steel box body. And the heat conductivity coefficient of the foam sandwich structure is low, heat preservation materials do not need to be arranged outside the box body, structure and function integration is achieved, parts of the sewage box are optimized, and installation is easier and more convenient.
