Description
Technical field
The present invention relates to a kind of glass lightweight felt and preparation method thereof, more particularly to a kind of nanometer titanium dioxide silica aerogel
Glass lightweight felt and preparation method thereof.
Technical background
In recent years, energy-conserving and environment-protective turn into the most concerned problem of people, and traditional organic insulation material is inflammable perishable to be lacked
The extensive use for limiting it in building field is fallen into, and there is poor thermal insulation property in inorganic heat insulation material, the shortcomings of density is big has
Significant limitation.Glass fibre is as the inorganic non-metallic material of another excellent performance, and not only thermal conductivity factor is low but also machine
Tool intensity is high, and it forms unorganic glass meltblown, because with good resilience, heat insulating effect is excellent, also has
Very excellent damping, sound absorption characteristics, advantageously reduce noise pollution, improve working environment, are widely used in architecture indoor, disappear
Sound system, the vehicles, refrigeration plant, the damping of household electrical appliance, sound absorption, noise reduction process, effect are very good.The life of mineral wool
Production is broadly divided into flame injection and centrifugal blast, but flame injection energy consumption is higher, is gradually replaced by centrifugal blast technique.In glass
In the preparation technology of glass blanket, wet method and dry method are broadly divided into.The blanket unit weight of wet production is higher, general fiber and particle
It is compound mainly to use binding agent by fiber solidifying into felt using wet processing dry process felt more.
Aerosil has nano-porous structure, and general aerosil density is relatively low, with special
Porous network structure, porosity is more than 90%, and most of gas cell distribution is below 50 nanometers, less than being averaged certainly for air molecule
It is difficult to collide by 70 nanometers of journey, between air molecule, with relatively low thermal conductivity factor.The preparation method of aerogel composite
Two kinds are broadly divided into, is gel molding in integral and grain forming method respectively.For gel molding in integral, in collosol and gel mistake
Enhancing phase is introduced in journey, Monolithic aerogel composite is finally given；For grain forming method, by the nano-pore gas prepared
Gel particle powder adds enhancing mutually and in binding agent, and the complex of post forming is made up of molding or moulding by casting.
The Chinese invention patent of Application No. 201310309064.5 discloses a kind of blanket of glass wool and silica airsetting
The method of glue mixing felt, the invention is to prepare mineral wool using centrifugal blast technique, sprays resinoid bond, while by dioxy
SiClx aeroge slurry is sprayed at blanket of glass wool surface, forms the composite that blanket is superimposed with aeroge, its advantage is to prepare
The composite gone out has excellent mechanical performance, good heat-insulating property and sound absorbing capabilities.It has the disadvantage the requirement to equipment
Height, virtually adds cost, and the content of aeroge is larger in the aeroge combination mat prepared in addition so that the rigidity of combination mat
It is big flexible not enough, limit its application in some fields.
The Chinese invention patent of Application No. 201310309201.5 discloses a kind of dry method mineral wool and silica gas
Gel complex material and preparation method thereof, the invention is that aerosil is filled in mineral wool gap, passes through phenol
Aerosil and mineral wool are combined by urea formaldehyde binding agent, constitute fiber and Particles dispersed type composite.Profit
Mineral wool, sprinkling phenolic resin adhesive and aerosil mixture are prepared with centrifugal blast technique, its advantage is this
Composite has excellent mechanical performance, good heat-insulating property and sound absorbing capabilities.It has the disadvantage using phenolic resin bonded
Agent and aerosil mixture, the thermal conductivity factor of combination mat slightly has increase while the highest for reducing combination mat uses temperature
Degree, limits its application in high-temperature field.
Content in two patents as described above, aerosil combination mat prepared by prior art shared by aeroge compared with
Many, equipment requirement is high, considerably increases cost, the rigidity of additional mixing felt is big flexible not enough, and the effect of sound-insulating and heat-insulating is simultaneously paid no attention to
Think, therefore a kind of new mixing felt technique of urgent need carrys out the more excellent aeroge Chopped Strand Mat of processability.
The content of the invention
The purpose of the present invention is intended to overcome the deficiencies in the prior art, and there is provided a kind of small flexible big, sound isolating and heat insulating performance of rigidity
More excellent nanometer titanium dioxide silica aerogel glass lightweight felt and preparation method thereof.
To realize that the technical scheme that the purpose of the present invention is used is：A kind of nanometer titanium dioxide silica aerogel glass lightweight
Felt, it is characterised in that described glass lightweight felt by surface uniform adhesion silica aerogel particles glass fiber level
Arrangement is formed, felt thickness direction without the glass fibre extended vertically through, it is a diameter of 1 micron -4 microns of glass fiber, long
Spend for 5 millimeters -30 millimeters, in a contact form between filament and filament, greatly reduce overlapping area, so as to increase heat
Resistance, significantly reduces the thermal conductivity factor of Chopped Strand Mat.
The particle diameter of silica aerogel particles is 10 nanometers -100 nanometers, glass fiber superficial silicon dioxide silica aerogel
Adhesion layer thickness is 50 nanometers -500 nanometers, and the uncovered ratio of fiber surface is 5%-10%, aerosil
Weight ratio of the grain in felt is 0.1%-1%, by Venturi effect so that silica aerogel particles uniform adsorption is in glass
In the gap being present between glass fibre of glass filament surface rather than monoblock, the flexibility for adding Chopped Strand Mat reduces it
Rigidity, makes it have excellent sound absorption qualities, the unit weight of felt is every cube 5 kilograms -20 kilograms, and the compression rebound rate of felt is
20%-30%, the porosity of felt is 70%-90%, and the thermal conductivity factor of the heat-insulated Chopped Strand Mat of aerosil light sound-proof is
0.008-0.015W/mK, in the leading level in the world.
Present invention also offers a kind of preparation method of nanometer titanium dioxide silica aerogel glass lightweight felt, it is characterised in that bag
Include following steps：
(1) glass fiber is sprayed into from Venturi tube top, flow is 100 kilograms -300 kilograms, glass fibers per hour
Dimension silk descends slowly and lightly in Venturi tube, and Venturi tube length is 3 meters -5 meters, and upper and lower side aperture ratio is 1: 3-5；
(2) one air inlet is set in the contraction section of Venturi tube, silica aerogel particles is sprayed into from air inlet, flow
Measure as 0.1 kilogram -0.5 kilogram per hour, glass fiber entrance is 1 with silica aerogel particles entrance spacing
- 2 meters of rice；
(3) the ratio between gentle gel flow of flow of adjustment glass fiber, it is to avoid silica aerogel particles are in fiber
Silk surface multi-layer pushes away product so that aerosil is uniformly distributed in filament surface；
(4) glass fiber slows down in Venturi tube lower end, tends to parallel whereabouts by longitudinal direction whereabouts, is produced with aerogel particle
Raw initiative sharp impacts, make the unstable particle of absorption drop, and the particle dropped enters one with the unadsorbed surface of glass fiber
Step is adsorbed；
(5) glass fiber goes out behind Venturi tube bottom, and slow parallel depositions are on a moving belt；
(6) rotating speed of bottom conveyor is adjusted, the thickness of the heat-insulated Chopped Strand Mat of aerosil light sound-proof is controlled.
The beneficial effects of the invention are as follows：(1) by Venturi effect silica aerogel particles uniform adsorption is existed
