Fireproof flame-retardant metal honeycomb plate

The utility model discloses a fireproof flame-retardant metal cellular board which comprises a cellular board body and further comprises a side board a and a side board b, the side board a is fixedly connected to the upper surface of the cellular board body, the side board b is fixedly connected to the lower surface of the cellular board body, and the side board a and the side board b are each composed of a flame-retardant board layer, a heat insulation board layer, a flame-retardant foaming agent layer and a high-temperature-resistant flat board layer. And the two sides of the surface of the honeycomb plate are connected with the high-temperature-resistant flat plate layers of the side plate a and the side plate b. The flame-retardant plate layer, the heat insulation plate layer, the flame-retardant foaming agent layer and the high-temperature-resistant flat plate layer are arranged on the two sides of the honeycomb plate, so that the effect of two-time flame retardance is achieved, and the flame-retardant a
