The invention relates to the technical field of honeycomb plates for refrigerator cars, in particular to a honeycomb composite plate for a refrigerator car and a preparation method thereof.The honeycomb composite plate for the refrigerator car comprises a panel layer, PU glue, a barrier film, spunlace felt, a particle core material and a honeycomb core material, and the particle core material is filled in the honeycomb core material; the upper ends and the lower ends of a plurality of honeycomb core materials which are neatly and tightly arranged are respectively coated with a layer of spunlaced felt, and the honeycomb core plates are generated through hot-press forming treatment. The upper end and the lower end of the honeycomb core plate are each provided with a barrier film in a laid mode, and heat-sealing core plates are generated through vacuum heat-sealing treatment. The honeycomb composite board for the refrigerator car is formed by hot-pressing and bonding an upper panel layer, a heat-sealing core board and a lower panel layer from top to bottom, wherein the upper end face of the heat-sealing core board is evenly wetted with PU glue, and the upper end face of the lower panel layer is evenly wetted with PU glue. The problems that the production efficiency is low, the plate is thick and heavy, and bubbling is prone to occurring in the current mainstream technology can be solved.
