In conjunction with shown in Fig. 1 to Fig. 4, a kind of barrier steam heat-insulating material, material includes the insulation as tunnel heat-barrier material
Felt 1；And the close membrane 2 as water vapor rejection material, close membrane 2 are wrapped in 1 outer surface of felt insulation；And several fixing pieces
3, close membrane 2 of the fixing piece 3 on felt insulation 1 and the positive and negative surface of felt insulation 1, for close membrane 2 to be pressed on felt insulation 1
On positive and negative surface.Due to felt insulation 1 be difficult by adhesive it is be bonded with close membrane 2 securely, in order to be easy to spread after material is installed
Hang waterproof outer material and be unlikely to close membrane 2 is made to fall off it is sagging, in the material between position using fixing piece 3 to 2 He of close membrane
Felt insulation 1 carries out secondary fixation.
Wherein, felt insulation 1 is inorganic nano powder composite adiabatic felt, by inorfil and inorganic nano powder mixing system
At, and felt insulation is the network for being evenly distributed with nano-pore, and the aperture of nano-pore is average lower than air molecule under normal pressure
Free path, so as to avoid the convective heat transfer of air, and the extremely low bulk density and nanometer grid structure of inorganic nano powder
Crooked route also prevents gaseous state and solid-state heat transfer, and the gap wall for tending to " infinite more " can be such that heat radiation minimizes.Nothing
Machine nanometer powder is selected from MgO, ZnO, CuO, SiO2、Al2O3、TiC2, SiC or TiB2One of or it is a variety of, inorfil is selected from
One of glass fibre, quartz glass fibre, boron fibre or ceramic fibre.Its preparation step includes: (1) using mass concentration
For 30% hydrofluoric acid, oxide etch 1.5h is carried out to quartz glass fibre at a temperature of 60 DEG C, increases quartz glass fibre table
Face polarity and roughness；After processing with SiO2Nanometer powder mixing, mashing, and utilization ultrasonic wave decentralized processing, power 300W,
Processing 18min is obtained a homogeneous mixture；(2) by mixture vacuum dehydration, repressurization molding, then in nitrogen protection atmosphere into
Row solidification, first rises to 150 DEG C from room temperature with the heating rate of 9 DEG C/min and keeps the temperature 0.6h, then with the heating rate liter of 5 DEG C/min
To 250 DEG C and 0.6h is kept the temperature, finally rise to 300 DEG C with the heating rate of 2 DEG C/min and keeps the temperature 1.5h to get to being evenly distributed with
The network felt insulation of nano-pore.The thermal coefficient of the felt insulation 1 significantly reduces, most preferably arrival 0.011W/ (mK), and close
It spends relatively also very small.
Wherein, close membrane 2 is high-temperature resistant water vapour close membrane, and prepare raw material includes butyl acetate, poly- first in parts by weight
Base amylene, polyimides, polyacrylate, modified carbon nano-tube, inorganic high-temperature resistant auxiliary agent, glycidyl methacrylate and

4h is mixed in ester, polymethylpentene, polyimides, polyacrylate, modified carbon nano-tube and inorganic high-temperature resistant auxiliary agent, obtains
Mixed raw material；(2) glycidyl methacrylate and dibenzoyl peroxide are added in mixed raw material, is sufficiently stirred, In
Alkaline graft reaction 3h is carried out at 60 DEG C, obtains modified mixed raw material；(3) at 280 DEG C, modified mixed raw material is squeezed
Out, just embryophoric membrane is obtained, then first embryophoric membrane is pressed, is cooled down；(4) it is returned after cooling by the heat treatment of 40 DEG C of hot wind drying tunnels
Multiple sizing, last trimming, winding obtain high-temperature resistant water vapour close membrane.The percent thermal shrinkage of the close membrane 2 is at 150 DEG C
0.02% or so, surface wettability tension can reach 61mN/m before sided corona treatment, and water vapor transmittance is minimum up to 2.19 × 10-6g/
m2Day, thus it can effectively obstruct steam and to guarantee heat insulation extends making for heat-barrier material through heat-barrier material
Use the service life.
Particularly, fixing piece 3 is nylon mother buckle structure, including sub-buckle 31 and female thread 32, and sub-buckle 31 passes through 1 He of felt insulation
It forms a fixed connection after close membrane 2 with insertion female thread 32.Small, the good airproof performance of this design perforation, to the heat insulation of material entirety
Steam performance will not impact.
The end of sub-buckle 31 is formed with prominent ring 34, and the inner face of female thread 32 is provided with slot 35, opens on the cell wall of slot 35
There are four movable chamber 36, limited block 37 is equipped in each movable chamber 36, the outside of limited block 37 is equipped with chamfering 371, limited block
37 inside is equipped with spring 38, and limited block 37 is movably connected in movable chamber 36 by spring 38.When in use, by sub-buckle 31
End pass through two layers of close membrane 2 and felt insulation 1 after, be inserted into slot 35, prominent ring 34 pushes limited block 37 to movable chamber
36 contracts, spring 38 compress, and when prominent ring 34 passes completely through limited block 37, the rebound of limited block 37 is against in sub-buckle 31, shape
At locking, thus will not be separated again between sub-buckle 31 and female thread 32.
Particularly, the inner face of sub-buckle 31 and female thread 32 is equipped with water proof ring 33, water proof ring 33 by inner ring the third solidifying waterproof
The polyethylene layer 332 of material layer 331 and outer ring connection composition.After the docking of nylon mother buckle structure, water proof ring 33 can be against correspondence
2 surface of close membrane of side, and a certain amount of compressive deformation is generated, to prevent water from entering in primary and secondary buckle structure and be worn from the position
Saturating entire material, is further ensured that the anti-steam effect of material entirety.
In terms of size Control, material with a thickness of 8-10mm, the circumferential spacing on material of fixing piece 3 is 25-35cm, is indulged
