Description
Technical field
Building material technical field is the utility model is related to, more particularly to a kind of aeroge composite fibre Nomex.
Background technology
Aeroge is a kind of new nanoporous, the heat preserving and insulating material of low-density, and it is that current quality is most light, heat-insulated
The best solid-state material of performance, the thermal conductivity of its normal temperature can as little as 0.0131W m-1 K-1, density low can arrive 0.003g/cm3,
Porosity may be up to 99.8%, and specific surface area is up to 1000m2/g.But its low intensity, fragility are big, existing process is difficult to prepare greatly
Monolithic aerogel, and its effect of heat insulation is poor at high temperature, limit its application on building field.
At present, glass mat by being immersed into the Ludox system of preparation at aged, drying by most of producers
Reason obtains integral SiO2Aerogel blanket, the SiO2It is micro- that aerogel blanket aeroge easily occurs during transport, construction and use
Little particle, the phenomenon of dust releasing, have impact on SiO2The performance and used life of aerogel blanket, and environment is polluted.
The content of the invention
The utility model is to overcome existing SiO present in background technology2Aerogel blanket is being transported, constructing and used
Easily occurs aeroge molecule in journey, the phenomenon of dust releasing thus influences SiO2The performance and used life of aerogel blanket
And the problem of being polluted to environment, and a kind of aeroge composite fibre Nomex is provided, the aeroge composite fibre Nomex,
The advantages of being provided simultaneously with glass mat and aeroge, it is free from environmental pollution without the phenomenon of dust releasing, service life length.
The invention for solving the technical problem can reach by following technical solution：The aeroge composite fibre Nomex,
Including Nomex main body, the Nomex main body sequentially consist of three layers of adiabatic layer of cloth A, one layer of aerogel particle A, three layers
Adiabatic layer of cloth B, one layer of aerogel particle B, three layers of adiabatic layer of cloth C.
The adiabatic layer of cloth A, adiabatic layer of cloth B and adiabatic layer of cloth C are selected from glass fabric, asbestos cloth, high silica fiber cloth
Or ceramic cloth.
The utility model can have the advantages that compared with above-mentioned background technology：The aeroge composite fibre pin
Felt is pierced, glass mat is combined with aeroge, situations such as avoiding the occurrence of dry linting, while production method is surpassed than tradition
Critical aspects are simpler, and cost is lower, and speed faster, and makes the product be provided simultaneously with glass（And other）Fibrofelt and airsetting
The advantages of glue；Compared with conventional supercritical fluid method preparation method, solving SiO2Aerogel blanket is during transport, construction and use
Easily while there is the problem of aeroge molecule, dust releasing, it is excellent to possess that Nomex process is simple, manufacturing speed is fast
Point, be advantageous to mass produce.

3：1：3：1：3；The Nomex main body compacted depth is 1cm；The Nomex main body, which alternates, the vertical of acupuncture formation
Staple fiber, the vertical staple fiber interconnect with each layer fiber of feltwork.
Prepared by aeroge composite fibre Nomex, comprise the following steps：
Prepare 1）The processing of glass layer：Glass fiber is cut into 60mm first, staple glass fiber is inputted and combed
Reason machine；Staple glass fiber is combed into the monofilament of one one by carding machine, and lapping machine is conveyed to after forming very thin feltwork layer；
The stacking of mat stratum reticulare is reached 1mm thickness by lapping machine；Then acupuncture is carried out to feltwork using needing machine, is coupled to each other fiber,
As the acupuncture glass mat with some strength；
2）Aerogel particle：The airsetting rubber powder size used is 1-2mm；
3）The preparation of aeroge composite fibre Nomex：First, in coating machine upper berth triplex glass fiber cloth layer of cloth；Afterwards
By above-mentioned steps 2）The aerogel particle of preparation is uniformly sprayed at glass layer and forms an aeroge bisque, aeroge bisque
Thickness is 1mm；Then proceed to spread three glass layers, aeroge fine powder is uniformly sprayed at into glass layer forms aeroge
Bisque, aforesaid operations are continued cycling through, until 10 composite bed layings finish, the above-mentioned material laid are delivered to roll squeezer,
Through roll thickness be 1cm aeroge Nomex.
