Through the structural arrangement, the molded polystyrene board 100 is used as a bottom board, and has the advantages of low heat conductivity coefficient, good energy saving performance, good heat insulation performance and light volume weight. Meanwhile, the molded polystyrene board 100 has good dimensional stability and is not easy to expand with heat and contract with cold. Vertical-wire rock wool insulation tape 200 is bonded to the molded polystyrene board 100 by a layer of bonding mortar 200. The vertical-filament rock wool heat preservation belt 200 has excellent fireproof performance, when the outer side of the vertical-filament rock wool heat preservation belt 200 is in contact with a fire source, the temperature of the fire-facing surface is high, but after the vertical-filament rock wool heat preservation belt 200 has the blocking effect, the temperature conduction capability of the fire-facing surface is low, the molded polystyrene board 100 can be effectively protected, and the phenomenon that the molded polystyrene board 100 is hot-melted or ignited is prevented. Simultaneously, the tensile strength and the compressive strength of vertical silk rock wool heat preservation area 200 are higher, and then can promote the intensity of whole unilateral fire prevention insulation board structure. The heat conductivity coefficient of the vertical-wire rock wool heat-insulating belt 200 is close to that of the molded polystyrene board 100, so that model calculation is facilitated during energy-saving design of a building outer wall system.
