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.

    本发明公开了一种轨道车辆污物箱,包括上箱体和底板,所述上箱体和底板均为泡沫夹芯结构,所述上箱体胶粘设于所述底板上,所述泡沫夹芯结构包括芯层以及通过胶膜层胶粘设于所述芯层内外侧的内蒙皮层和外蒙皮层,所述芯层包括骨架和泡沫层,所述泡沫层设于所述骨架和所述胶膜层围成的空间中。本发明还提供一种轨道车辆污物箱的制备方法。本发明的轨道车辆污物箱的上箱体和底板主体材质为内置骨架的泡沫夹芯结构,具有轻质高强的特点,自重轻,强度满足要求,整体刚度大于不锈钢箱体刚度。且泡沫夹芯结构的导热系数低,在箱体外不需要再设置保温材料,实现结构功能一体化,优化了污物箱零部件,安装更加简便。
