▎ 摘　　要

NOVELTY - Heating floor comprises heating panel that has heating function, have foaming sandwich layer of the thermal-insulated function of heat preservation and the fire-retardant insulation board that has fire-retardant insulating function, heating panel, foaming sandwich layer and fire-retardant insulation board bond from last to down in proper order, form sandwich structure, the heating panel is formed by compounding multiples of layers of epoxy resin prepreg through hot pressing, graphene heating coating is printed on epoxy resin prepreg in middle layer, a wire connecting assembly is arranged on heating panel, and graphene heating coating is connected with a power supply through the wire connecting assembly to form a heating circuit. USE - Heating floor for railway vehicle. ADVANTAGE - The floor realizes integrated design of heating floor sound insulation-light quality of the carriage satisfy the current rail traffic vehicle carriage floor light weight, functional requirement, the heating power and heating rate of the heating panel can be adjusted by adjusting the content of graphene graphene the heating coating and the coating bandwidth, and the heating requirement of each type of train carriage is satisfy of heating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the manufacturing method of heating floor for rail vehicle,involves preparing heating panel according to the requirements of thickness, heating and interlayer strength, arranging lead connecting assembly on heating panel, preparingfoaming core layer according to requirements of thickness, support, heat insulation and heat preservation, and preparing flame-retardant insulating plate according to requirements of thickness and flame-retardant insulation; and then, bonding heating panel, the foaming core layer and flame-retardant insulating plate into whole by using bonding glue, and curing bonding glue to obtain heating floor for railway vehicle. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of heating for floor vehicle of a heating floor for railway vehicle. 1Heating panel 2Foaming core material 3Flame-retardant insulating plate 6Adjacent graphite strip heating belt
