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.

    本发明涉及冷藏车蜂窝板技术领域,具体为一种冷藏车用蜂窝复合板及其制备方法,其中冷藏车用蜂窝复合板包括面板层、PU胶、阻隔膜、水刺毡、颗粒芯材和蜂窝芯材,所述蜂窝芯材内填充有颗粒芯材,若干个整齐紧密排列的蜂窝芯材上下两端各包覆有一层水刺毡且经过热压成型处理生成蜂窝芯板;所述蜂窝芯板上下两端各铺设有一层阻隔膜且经过真空热封处理生成热封芯板;所述冷藏车用蜂窝复合板由上层的面板层、上端面均匀淋湿有PU胶的热封芯板以及上端面均匀淋湿有PU胶的下层的面板层从上往下热压粘合而成,本发明制备的一种冷藏车用蜂窝复合板,能够解决目前主流工艺存在的生产效率低、板材厚度厚、重量重以及容易鼓泡的问题。
