[0025] exist Figure 1 and Figure 2 In the figure, by setting up a waterproof mechanism 3, the various structures of the waterproof mechanism 3 cooperate with each other, so that the roof waterproofing is more convenient and the waterproofing effect is better. The waterproof mechanism 3 includes an insulation layer 301, a vapor barrier layer 302, a coating layer 303, a first waterproof layer 304, a heat insulation layer 305, a second waterproof layer 306 and a water guide layer 307.

[0029] In summary, the metal roof waterproofing component is provided with an insulation layer 301. The insulation layer 301 is a polyurethane insulation board, which has low thermal conductivity, moisture resistance, waterproofness, and excellent fire resistance, flame retardancy, and high temperature resistance. Its thermal conductivity is only 0.018-0.023W / (m·K). The polyurethane insulation board also has a closed porosity of up to 90%, which can effectively prevent water seepage from the wall. By providing a vapor barrier layer 302, the vapor barrier layer 302 is a Dike vapor barrier membrane, which is provided between the metal substrate plate 2 and the insulation layer 301.
