Detailed Description
The following detailed description of the present application is provided in conjunction with the accompanying drawings, and it is to be understood that the following detailed description is merely illustrative of the application and is not to be construed as limiting the scope of the application, since numerous insubstantial modifications and adaptations of the application will be to those skilled in the art in light of the foregoing disclosure.

Because the insulation felt 1 is hard to be firmly adhered to the sealing film 2 through an adhesive, in order to easily lay the outer waterproof material after the installation of the material and prevent the sealing film 2 from falling down and sagging, the sealing film 2 and the insulation felt 1 are secondarily fixed by using a fixing piece 3 at the middle part of the material.
The heat insulation felt 1 is an inorganic nano powder composite heat insulation felt and is prepared by mixing inorganic fibers and inorganic nano powder, the heat insulation felt is of a grid structure with uniformly distributed nano holes, the pore diameter of the nano holes is lower than the average free path of air molecules under normal pressure, so that convection heat transfer of air is avoided, the extremely low volume density of the inorganic nano powder and the bending path of the nano grid structure also prevent gaseous and solid heat conduction, and the heat radiation can be reduced to the minimum by the aid of the gap walls which tend to infinity. The inorganic nano-powder is selected from MgO, znO, cuO, siO 2 、Al 2 O 3 、TiC 2 SiC or TiB 2 The inorganic fiber is selected from one of glass fiber, quartz glass fiber, boron fiber or ceramic fiber. The preparation method comprises the following steps: (1) Carrying out oxidation etching on quartz glass fiber for 1.5 hours at the temperature of 60 ℃ by adopting hydrofluoric acid with the mass concentration of 30%, and increasing the polarity and roughness of the surface of the quartz glass fiber; after treatment with SiO 2 Mixing the nanometer powder, pulping, performing ultrasonic dispersion treatment with power of 300W, and treating for 18min to obtain a uniform mixture; (2) And (3) vacuum dehydrating the mixture, pressurizing and forming, solidifying in a nitrogen protective atmosphere, heating from room temperature to 150 ℃ at a heating rate of 9 ℃/min and preserving heat for 0.6h, heating to 250 ℃ at a heating rate of 5 ℃/min and preserving heat for 0.6h, and heating to 300 ℃ at a heating rate of 2 ℃/min and preserving heat for 1.5h to obtain the grid-structure heat-insulating felt uniformly distributed with the nanopores. The thermal insulation blanket 1 has a significantly reduced thermal conductivity, optimally reaching 0.011W/(m·k), and a relatively small density.
The sealing film 2 is a high-temperature-resistant water vapor sealing film, and the preparation raw materials of the sealing film comprise butyl acetate, polymethylpentene, polyimide, polyacrylate, modified carbon nano tubes, inorganic high-temperature-resistant auxiliary agents, glycidyl methacrylate and dibenzoyl peroxide in parts by weight. Wherein the method comprises the steps ofThe modified carbon nanotube is obtained by acidizing the carbon nanotube with 70wt% concentrated nitric acid, wherein the treatment temperature is 62 ℃ and the treatment time is 1h; the inorganic high temperature resistant auxiliary agent is formed by mixing silicon dioxide and magnesium stearate, and the weight ratio of the silicon dioxide to the magnesium stearate is 4:1. The preparation method comprises the following steps: (2) Butyl acetate, polymethylpentene, polyimide, polyacrylate, modified carbon nano tube and inorganic high-temperature resistant auxiliary agent are mixed and stirred for 4 hours to obtain a mixed raw material; (2) Adding glycidyl methacrylate and dibenzoyl peroxide into the mixed raw material, fully stirring, and performing alkaline grafting reaction for 3 hours at 60 ℃ to obtain a modified mixed raw material; (3) Extruding the modified mixed raw materials at 280 ℃ to obtain a primary blank film, and then performing compression molding and cooling on the primary blank film; (4) And (3) after cooling, carrying out heat treatment on the mixture through a hot air drying tunnel at 40 ℃ to restore and shape, and finally trimming and rolling the mixture to obtain the high-temperature-resistant steam sealing film. The heat shrinkage rate of the sealing film 2 is about 0.02 percent at 150 ℃, the surface wetting tension can reach 61mN/m before corona treatment, and the water vapor permeability can reach 2.19 multiplied by 10 at the lowest -6 g/m 2 Day, whereby it effectively blocks the transmission of water vapor through the insulation material, thereby ensuring the insulation effect and extending the service life of the insulation material.
In particular, the fixing member 3 has a nylon snap structure, which includes a snap 31 and a snap 32, wherein the snap 31 is fixedly connected with the insert snap 32 after passing through the heat insulation felt 1 and the sealing film 2. The design has small perforation and good sealing performance, and can not influence the overall heat insulation and water vapor insulation performance of the material.

When in use, after the end of the sub-buckle 31 passes through the two layers of sealing films 2 and the heat insulation felt 1, the end is inserted into the slot 35, the protruding ring 34 pushes the limiting block 37 to shrink inwards towards the movable cavity 36, the spring 38 is compressed, and when the protruding ring 34 completely passes through the limiting block 37, the limiting block 37 is rebounded to abut against the sub-buckle 31 to form locking, so that the sub-buckle 31 and the female buckle 32 can not be separated any more.

After the nylon snap fastener structure is abutted, the waterproof ring 33 can be abutted against the surface of the sealing film 2 on the corresponding side, and a certain amount of compression deformation is generated, so that water is prevented from entering the snap fastener structure and penetrating through the whole material from the position, and the overall waterproof steam effect of the material is further ensured.
