Description

The composite of thermal acoustic insulation aerogel layer compound breath film
Technical field
The utility model is related to thermal acoustic insulation technical field, more particularly to a kind of thermal acoustic insulation aerogel layer composite ventilating The composite of film.
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 are 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.Current aerogel blanket is used in 400 DEG C of narrower temperature provinces, is not also fully played out the performance of aeroge Come.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of answering for thermal acoustic insulation aerogel layer compound breath film Condensation material, the composite flexibility is good, can be in extremely low -268 DEG C of temperature ~ 300 DEG C temperature environment without bursting by freezing, can be extensive It is used in long lifespan, anticorrosion, outdoor resistance to ultraviolet environments aging, adiabatic protection and the place of strong sound insulation.
In order to solve the above technical problems, the technical scheme that the utility model is used is:A kind of thermal acoustic insulation gas is provided The composite of gel layer compound breath film, including:Ventilative film layer, bonding connection layer and aerogel layer, described ventilative film layer It is bonding by bonding connection layer between aerogel layer.
In one preferred embodiment of the utility model, described ventilative film layer is eptfe membrane.
In one preferred embodiment of the utility model, described aerogel layer is aerosil layer.
Aerosil is a kind of solar heat protection heat-proof quality very outstanding light nanoporous amorphous solid material, 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).Make aerogel material in heat just because of these features There is very wide application potential in terms of, acoustics, optics, microelectronics, particle detection.
Aerosil characteristic
1st, thermal insulation
Silica aerogel material has extremely low thermal conductivity factor, 0.013-0.016W/ (mK) is can reach, less than quiet State air(0.024W/(m·K))Thermal conductivity coefficient, the 2-3 order of magnitude lower than corresponding inorganic insulating material.Even in 800 DEG C At a high temperature of its thermal conductivity factor just be 0.043W/ (mK).Do not decomposed under high temperature, no pernicious gas is released, and belongs 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, pass through 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 make use of to occupy a part of volume of solid material, so as to reduce the overall thermal conductivity of 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 it by with low as air Thermal conductivity.And it is less than 70nm hole in aeroge comprising a large amount of apertures, 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 It 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 small so that aeroge equally has minimum solid-state thermal conductivity.The heat of aeroge Conduct radiation is mainly the infrared emanation occurred in 3-5 μm of region, and it can effectively stop infrared hot spoke at normal temperatures Penetrate, but with the rise of temperature, the enhancing of infrared emanation permeability.In order to further reduce high-temperature infrared heat radiation, generally to Opacifier, such as carbon black, titanium dioxide are added in aeroge, the use of opacifier can substantially reduce the infrared hot spoke under high temperature 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 Material.This is the three-dimensional hole built by nano level silicon dioxide microparticle, and its porosity is up to 80-99.8%, the typical chi of hole The very little resistance for being the air molecule flowing in 1-100 nm, these nano level holes is very greatly, it is necessary to consume substantial amounts of incidence Noise wave energy so that the direction of transfer of noise wave energy changes, noise wave energy is as aeroge labyrinth inside duct Exponential damping is presented in the multi-direction stickiness dissipation effect of reciprocating vibration of generation, and substantial amounts of noise energy is absorbed by aeroge so that It is decreased obviously through the sound of aerogel layer, so as to show the effect of strong sound insulation.
In one preferred embodiment of the utility model, described bonding connection layer is fire-retardant polyurethane adhesive or contains There is the coating of aeroge.
The beneficial effects of the utility model are:
1st, the utility model overcomes aerosil loosely frangible, it is difficult to defect be used on a large scale, by titanium dioxide The composite of the compound eptfe membrane of silica aerogel layer just overcomes the loose frangible of aerosil and lacked Point, and the advantage of the thermal insulation having of aerosil and eptfe membrane and sound absorption sound insulation and noise reduction is combined more Get up so that thermal acoustic insulation effect is more preferable;The composite flexibility well can be in extremely low -268 DEG C of temperature ~ 300 DEG C temperature simultaneously Without bursting by freezing in environment, work not aging in more than 20 years under the ultraviolet that can be chronically exposed to outdoor exposure.
2nd, to solve other organic material fire protecting performances undesirable for composite of the present utility model, and inorganic material absorbs water Rate is big, easily " condensation ", construction when skin urtication the problems such as, fiberglass products, asbestos insulation quilt, silicate fibre can be substituted Fiber products etc. not environmentally, the conventional flex insulation material of poor thermal insulation property, can widely be used in long lifespan, anticorrosion, family Outer resistance to ultraviolet environments aging, adiabatic protection and strong sound insulation etc. place.
