Description
Technical field
The present invention relates to thermal acoustic insulation technical field, more particularly to a kind of thermal acoustic insulation aerogel layer compound breath film
Composite and its manufacture method.
Background technology
At present a large amount of insulation materials be, inorganic fireproof thermal-insulation mortar, foam glass, mineral wool, rock wool, polyphenyl second
Alkene foamed plastics and polyurethane foam plastics, above-mentioned material heat insulation effect is general；Aerogel blanket is to be aerosil
Material of main part, and be compound in enhancement fiber, such as glass fibre, pre-oxidized fibers, the flexible guarantor synthesized by special process
Adiabator.At present aerogel blanket is used in 400 DEG C of narrower temperature provinces, does not also fully play out the performance of aeroge
Come.
The content of the invention
The invention mainly solves the technical problem of providing a kind of composite wood of thermal acoustic insulation aerogel layer compound breath film
Material and its manufacture method, the composite flexibility is good, can be in -268 DEG C ~ 300 DEG C temperature environments of extremely low temperature without bursting by freezing, energy
Enough places for being widely used in life-span length, anticorrosion, aging outdoor resistance to ultraviolet environments, adiabatic protection and strong sound insulation.
To solve above-mentioned technical problem, one aspect of the present invention is：A kind of thermal acoustic insulation aeroge is provided
The composite of layer compound breath film, including：Ventilative film layer, bonding connection layer and aerogel layer, described ventilative film layer is gentle
It is bonding by bonding connection layer between gel layer.
In a preferred embodiment of the present invention, described ventilative film layer is eptfe membrane.
In a preferred embodiment of the present invention, described aerogel layer is aerosil layer.
Aerosil is a kind of very outstanding light nanoporous amorphous solid material of solar heat protection heat-proof quality, its
Porosity is up to 80-99.8%, and the typical sizes of hole are 1-100 nm, and specific surface area is 200-1000 m2/ g, and density can
It is low up to 3 kg/m3, room temperature thermal conductivity factor can be low up to 0.012 W/（m·K）.Just because of these features aerogel material is made in heat
, acoustics, optics, microelectronics, particle detection aspect have very wide application potential.
Aerosil characteristic
1st, thermal insulation
Silica aerogel material has extremely low thermal conductivity factor, can reach 0.013-0.016W/ (mK), empty less than static
Gas（0.024W/(m·K)）Thermal conductivity coefficient, the 2-3 order of magnitude lower than corresponding inorganic insulating material.Even if in 800 DEG C of height
Lower its thermal conductivity factor of temperature is just 0.043W/ (mK).Do not decompose under high temperature, release without pernicious gas, belong to environmental protection section bar
Material.
Why aeroge has so good insulating characteristicses relevant with its high porosity.The conduction of heat is mainly led to
Cross three kinds of approach to carry out, gas conduction, solid conduction, conduct radiation.In these three modes, by the heat of gas conduction
It is very little, therefore most of gas all has low-down thermal conductivity.Conventional heat-insulating material is all loose structure, and it is exactly
Air is make use of to occupy a part of volume of solid material, the thermal conductivity overall so as to reduce material.The hole of aeroge
Rate is more much greater than conventional insulation material, and it more than 95% is made up of air, determines that it will have low as air
Thermal conductivity.And the hole in aeroge comprising a large amount of apertures less than 70nm, 70nm is main component nitrogen and oxygen in air
Free path（Gas molecule collide twice between time in pass through distance assembly average）, therefore, it is intended that air is in gas
Will be unable to realize convection current in gel so that gas thermal conductivity is further reduced.The few solid skeletal of content is also in aeroge
It is made up of nano particle, its contact area is very little so that aeroge equally has minimum solid-state thermal conductivity.The heat of aeroge
Predominantly there is the infrared emanation in 3-5 μm of region in conduct radiation, it can effectively stop at normal temperatures infrared hot spoke
Penetrate, but with the rising of temperature, infrared emanation permeability strengthens.In order to further reduce high-temperature infrared heat radiation, generally to
Opacifier, such as carbon black, titanium dioxide, the use of opacifier is added to substantially reduce the infrared hot spoke under high temperature in aeroge
Penetrate.
Aerosil also has as a kind of nano-porous super thermal insulation material in addition to extremely low thermal conductivity
The characteristic of Ultralight and high thermal stability, it has widely in fields such as industrial, civilian, building, space flight and military affairs
Using.
2nd, sound-proofing
Due to the low acoustic-velocity characteristic of aerosil, it or a kind of preferable acoustical delay or high temperature acoustic material.This
It is the three-dimensional hole built by nano level silicon dioxide microparticle, its porosity is up to 80-99.8%, and the typical sizes of hole are
1-100 nm, the resistance of the air molecule flowing in these nano level holes is very big, needs to consume substantial amounts of incident-noise
Wave energy so that the direction of transfer of noise wave energy changes, noise wave energy occurs inside duct as aeroge labyrinth
Multi-direction stickiness dissipation effect of reciprocating vibration is presented exponential damping, and substantial amounts of noise energy is absorbed by aeroge so that pass through
The sound of aerogel layer is decreased obviously, so as to show the effect of strong sound insulation.
In a preferred embodiment of the present invention, described bonding connection layer is fire-retardant polyurethane adhesive or contains gas
The coating of gel.
To solve above-mentioned technical problem, another technical solution used in the present invention is：A kind of thermal acoustic insulation airsetting is provided
The manufacture method of the composite of glue-line compound breath film, comprises the following steps：
Technological preparation, ventilated membrane is unreeled, and roller coating bonding connection layer, lays aeroge on ventilated membrane, is sprayed on aerogel layer viscous
Knot articulamentum, covers ventilated membrane, heating rolling solidification, winding on aerogel layer.
In a preferred embodiment of the present invention, the temperature of described heating rolling solidification is 80 ~ 130 DEG C.
The invention has the beneficial effects as follows：
1st, the present invention overcomes aerosil loosely frangible, it is difficult to defect is used on a large scale, by aerosil
The composite of the compound eptfe membrane of layer just overcomes the loose frangible shortcoming of aerosil, and by two
The thermal insulation having of silica aerogel and eptfe membrane and the advantage of sound absorption sound insulation and noise reduction combine more so that
Thermal acoustic insulation effect is more preferable；Simultaneously the composite flexibility well can be in -268 DEG C ~ 300 DEG C temperature environments of extremely low temperature without jelly
Split, can be chronically exposed under the ultraviolet of outdoor exposure work more than 20 years it is not aging.
2nd, to solve other organic material fire protecting performances undesirable for composite of the invention, and inorganic material water absorption rate
When greatly, easily " condensing ", constructing the problems such as skin urtication, fiberglass products, asbestos insulation quilt, silicate fiber can be substituted
Product etc. not environmentally, the conventional flex insulation material of poor thermal insulation property, can widely be used in life-span length, anticorrosion, open air
Resistance to ultraviolet environments are aging, adiabatic protection and strong sound insulation etc. place.
