Embodiment 1
[0029] Please refer to the attached figure 1 And attached figure 2 , which discloses Embodiment 1 of the present invention, including an outer panel 1, a fireproof and heat insulating layer 2, a supporting surface 3, a cement tank 4, an inner panel 5, and a cooling device 6.
[0030] A fire-proof and heat-insulating hollow board for a building. A closed hollow structure is formed by the upper and lower parallel outer panel 1, inner panel 5 and cement tank 4. The material of the outer panel 1 and inner panel 5 is phenolic foam insulation board, and the cement tank 4 is inlaid with Steel mesh to improve the strength and stability of the hollow board, the fireproof layer 2 is composed of 30 parts of aluminized polyimide, 35 parts of silicon nitride, 40 parts of epoxy / benzoxazine resin base and 5 parts of tri(2, 3-dichloropropyl) ester, and connected to the outer panel 1 and the support surface 3 in pairs, the heat sink 6 includes a copper metal heat conduction plate 61, a polyc...
Embodiment 2
[0032] Please refer to the attached figure 1 , which discloses Embodiment 2 of the present invention, this embodiment is similar to Embodiment 1, the difference is that the fireproof layer 2 is made of 40 parts of aluminized polyimide, 45 parts of silicon nitride, and 60 parts of epoxy / benzoxazine resin base and 10 parts of tris(2,3-dichloropropyl) phosphate, the heat dissipation medium of the heat sink 6 is expanded perlite, the metal heat conduction plate 61 is an aluminum sheet, and the material of the shell 62 is silicon oxide with a gradual cross-sectional area The range is 10-48cm 2 , the incremental range of the bulk density of the first filling layer 63 is 0.7-1.9g / cm 3 , the increasing range of the bulk density of the second filling layer 64 is 2.0-2.5g / cm 3 , the bulk density of the third filling layer 65 increases in the range of 2.4-3.5g / cm 3 .
