Description
Technical field
The present invention relates to building material technical field, in particular to a kind of aeroge composite fibre Nomex and its production side
Method.
Background technique
Aeroge is the heat preserving and insulating material of the novel nanoporous of one kind, low-density, it is that current quality is most light, heat-insulated
The best solid-state material of performance, the thermal conductivity of room temperature can be as low as 0.003g/ down to 0.0131Wm-1K-1, density
Cm3, porosity may be up to 99.8%, and specific surface area is up to 1000m2/g.But its intensity is low, brittleness is big, prior art is difficult to make
Standby Monolithic aerogel big out, and its heat insulation is poor at high temperature, limit its application on building field.
Currently, glass mat by being immersed into the silica solution system of preparation at aged, drying by most of producers
Reason obtains integrated SiO2 aerogel blanket, which is easy to appear aeroge in transport, construction and use process
The phenomenon that molecule, dust releasing, the performance and used life of SiO2 aerogel blanket is affected, and polluted the environment.
Summary of the invention
The invention reside in overcome existing SiO2 aerogel blanket present in background technique in transport, construction and use process
The phenomenon that being easy to appear aeroge molecule, dust releasing affects the performance and used life of SiO2 aerogel blanket and right
The problem of environment pollutes, and a kind of aeroge composite fibre Nomex is provided, the aeroge composite fibre Nomex, simultaneously
Have the advantages of glass mat and aeroge, there is no the phenomenon that dust releasing, long service life is free from environmental pollution.The present invention
Additionally provide a kind of preparation method of aeroge composite fibre Nomex.
The present invention solves the problems, such as that it 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 insulation layer of cloth A, one layer of aerogel particle A, three layers of insulation
Layer of cloth B, one layer of aerogel particle B, three layers of insulation layer of cloth C.
The insulation layer of cloth A, insulation layer of cloth B and insulation layer of cloth C are selected from glass fabric, asbestos cloth, high silica fiber cloth
Or ceramic cloth.
The present invention also provides a kind of preparation methods of aeroge composite fibre Nomex, comprising the following steps:
(1) filament of glass fiber is chopped into the short silk of glass fibre, by shredding, combing, lapping, very thin feltwork is spread
It is three layers folded, one layer of aerogel particle layer is being spread above later；
(2) three layers of glass fibre feltwork of step (1) aerogel particle layer upper berth is repaved into one layer of aerogel particle layer again,
Last three layers of feltwork of laying is finally in layer structure, then carries out positive purl thorn, the weight of every layer of control to feltwork by needing machine
Aeroge composite fibre Nomex is made to reach preset standard weights in amount.
The present invention can have the following beneficial effects: the aeroge composite fibre Nomex compared with above-mentioned background technique,
Situations such as glass mat is combined with aeroge, avoids the occurrence of picking, while making production method than conventional supercritical fluid side
Formula is simpler, and cost is lower, and speed faster, and makes the product be provided simultaneously with the excellent of glass (and other) fibrofelt and aeroge
Point；Compared with conventional supercritical fluid method preparation method, it is easy solving SiO2 aerogel blanket in transport, construction and use process
While the problem of existing aeroge molecule, dust releasing, has the advantage that Nomex process is simple, manufacturing speed is fast, have
Conducive to large-scale production.
Detailed description of the invention
Attached drawing 1 is structural schematic diagram of the invention.
In figure: 1, being insulated layer of cloth A, 2, aerogel particle A, 3, insulation layer of cloth B, 4, aerogel particle B, 5, insulation layer of cloth C.
Specific embodiment:
The invention will be further described below in conjunction with the accompanying drawings and the specific embodiments:
Embodiment 1:
As shown in Figure 1, a kind of aeroge composite fibre Nomex, including Nomex main body, the Nomex main body is under
It is supreme to be followed successively by three layers of insulation layer of cloth A1, one layer of aerogel particle A2, three layers of insulation layer of cloth B3, one layer of aerogel particle B4, three
Layer insulation layer of cloth C5；The insulation layer of cloth A1, insulation layer of cloth B3 and insulation layer of cloth C5 are glass fabric；Three layers of adiabatic cloth
Layer A1, one layer of aerogel particle A2, three layers of insulation layer of cloth B3, one layer of aerogel particle B4, three layers of insulation layer of cloth C5 thickness ratio are
3:1:3:1:3；The Nomex main body compacted thickness is 1cm；The Nomex main body alternate have needling shape at it is vertical
Staple fiber, the vertical staple fiber interconnect with each layer fiber of feltwork.
The preparation of aeroge composite fibre Nomex, comprising the following steps:
Prepare the processing of 1) glass layer: glass fiber being cut into 60mm first, staple glass fiber is inputted and is combed
Reason machine；Staple glass fiber is combed into monofilament one by one by carding machine, is conveyed to lapping machine after forming very thin feltwork layer；
The stacking of mat stratum reticulare is reached 1mm thickness by lapping machine；Then needle thorn is carried out to feltwork using needing machine, is coupled to each other fiber,
Glass mat is pierced as the needle with some strength；
2) aerogel particle: the airsetting rubber powder size used is 1-2mm；
3) preparation of aeroge composite fibre Nomex: firstly, in coating machine upper berth triplex glass fiber cloth layer of cloth；Later
By above-mentioned steps 2) preparation aerogel particle be uniformly sprayed at glass layer formed an aeroge bisque, aeroge bisque
With a thickness of 1mm；It then proceedes to spread three glass layers, aeroge fine powder is uniformly sprayed at glass layer and forms aeroge
Bisque continues cycling through aforesaid operations, until 10 composite layer layings finish, the above-mentioned material laid is delivered to roll squeezer,
Rolled with a thickness of 1cm aeroge Nomex.
Aeroge composite fibre Nomex of the present invention combines glass mat with aeroge, avoids the occurrence of picking etc.
Situation, while keeping production method simpler than conventional supercritical fluid mode, cost is lower, and speed faster, and makes the product simultaneously
Has the advantages of glass (and other) fibrofelt and aeroge；Compared with conventional supercritical fluid method preparation method, solving SiO2 gas
While gel felt is easy to appear the problem of aeroge molecule, dust releasing in transport, construction and use process, have
The advantage that Nomex process is simple, manufacturing speed is fast.
