Description
Technical field
The present invention relates to a kind of aerosil felt, particularly relate to the aerosil felt of a kind of strong weatherability
And preparation method thereof.
Background technology
Along with becoming increasingly conspicuous of current energy source problem, energy-saving and emission-reduction have become as the focus of current research.Silicon dioxide gas
Gel rubber material is due to the heat-insulating capability of its excellence, and the use in field of thermal insulation about comes about extensive, uses nano silicon airsetting
Glue material, not only can greatly reduce insulation layer thickness, and owing to silica aerogel material is substantially all by dioxy
SiClx and glass fibre composition, do not have any harmful pollution for environment.It it is preferable insulation material succedaneum.
But, the aerosil felt currently used needs to be used in combination with other material in use process mostly,
Especially at building field, with using time lengthening, surface gel can be because contacting gradually efflorescence, with contactant with sky, moisture etc.
The cohesive force of body dies down, and affects the serviceability of product, uses the manufacture method of VIP plate at present, is sealed by aerogel blanket aluminum film
After dress, evacuation can slow down problems to a certain extent, but after still suffering from extending gas leakage in time, aluminium foil is combined with aeroge
Power dies down and is difficult to make the problem of coiled material, limits the expansion of nanometer titanium dioxide silica aerogel range.
Summary of the invention
It is an object of the invention to: for the defect of prior art, it is proposed that the silicon dioxide airsetting of a kind of strong weatherability
Rubber mat and preparation method thereof.
The technical solution adopted in the present invention is: the aerosil felt of a kind of strong weatherability, including nano-silica
SiClx aerogel blanket body, pre-enhancement layer, tack coat and protective layer, described tack coat is located at nano silicon aerogel blanket
The surface of body, described protective layer sets the top of tack coat, and described pre-enhancement layer is positioned at nano silicon aerogel blanket
Between body and tack coat, described protective layer is that polyamide fibre cloth, woven dacron, macromolecule membrane or aluminum foil material are constituted, described
Pre-enhancement layer is that glass fiber material is constituted, and described tack coat is pressure sensitive adhesive or hot melt adhesive material composition.
In the present invention: the thickness of described protective layer is 0.1 1.5mm.
In the present invention: the thickness of described pre-enhancement layer is 0.1 0.5mm.
In the present invention: described tack coat is 0.15 0.35mm.
A kind of method of aerosil felt preparing strong weatherability, comprises the steps:
(1), after nano silicon aerogel blanket body completes, before hydrophobic treatment or pre-on its surface after hydrophobic treatment
Lay one layer of pre-enhancement layer being made up of glass fiber material, then by needle-punching method with nano silicon aerogel blanket originally
Body strengthens in advance；
(2), on pre-enhancement layer, one layer of tack coat being made up of pressure sensitive adhesive or hot melt adhesive material is laid；
(3), by pre-thermo-compression bonding layer, then its surface hot pressing one layer by polyamide fibre cloth, woven dacron, macromolecule membrane or aluminium foil
The protective layer that material is constituted, can be steady in a long-term after preparing aerosil felt external application mortar.
After using technique scheme, the invention have the benefit that by dewatering nano aerosil felt
Surface pre-add enhancement layer also strengthens in advance with aerosil felt, then applies hot melt adhesive film, then lays on hot melt adhesive film
The protective layers such as aluminium foil, it is to avoid aerosil felt contacts with air, moisture etc., slow down the efflorescence speed of surface gel
Degree, simultaneously as the existence of pre-enhancement layer, the strength and stability that tack coat is combined with aerogel blanket is greatly enhanced, and coordinates not
Same protective layer, can meet the stability and persistency being combined with different materials.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
Embodiment 1
Utilize the nano silicon aerogel blanket after hydrophobic treatment, lay the thick loose glass fibers of one layer of 0.1mm on surface in advance
Wei Bu, is then strengthened with nanometer titanium dioxide silica aerogel by needle-punching method, the most pre-hot pressing 0.15mmPO hot melt adhesive film in advance, then
At one layer of aluminium foil of surface hot pressing, prepared product in an outdoor environment can be steady in a long-term.
Embodiment 2
Utilize the nano silicon aerogel blanket after hydrophobic treatment, lay the thick glass fabric of one layer of 0.1mm on surface in advance,
Then strengthened in advance with nanometer titanium dioxide silica aerogel by needle-punching method, the most pre-hot pressing 0.25mmTPU hot melt adhesive film, then at table
Fever sensation of the face one layer of polyamide fibre cloth of pressure, can be steady in a long-term after preparing product external application mortar.
Embodiment 3
Utilize the nano silicon aerogel blanket after hydrophobic treatment, lay the thick glass fibre of one layer of 0.5mm in advance on surface, so
Strengthened in advance with nanometer titanium dioxide silica aerogel by needle-punching method afterwards, the most pre-quick glue of hot pressing 0.35mm, then in surface hot pressing one
Layer woven dacron, can be steady in a long-term after preparing product external application mortar.
In the present invention: protective layer and the existence of tack coat, completely cut off aerogel blanket and contacted with the direct of empty gas and water, subtracted
The weak efflorescence speed of aeroge surface gel, meanwhile, selects the form of protective layer, can meet strong with the combination of different materials
Degree demand.For ensureing preferable product stability, nano silicon aerogel blanket is preferred with the product after hydrophobic treatment.Bonding
Layer can be pressure sensitive adhesive, PUR etc., is preferred with hot melt adhesive film, does not has solvent, the most do not produce low point in the course of processing
Sub-compound, will not damage the structure of nanometer titanium dioxide silica aerogel and affect the heat conductivility of product.
For strengthening intensity and the persistency that tack coat is combined with nanometer titanium dioxide silica aerogel, in advance at nano silicon
A thin layer bonding enhancement layer such as glass fibre thin layer etc. is laid on aerogel blanket surface, and pre-with aerogel blanket by methods such as acupunctures
Strengthen, the strength and stability of combination can be obviously improved.
Above the detailed description of the invention of the present invention is described, but the present invention is not limited to above description.For this
For the technical staff in field, any equal amendment to the technical program and replacement are all within the scope of the invention.Cause
This, the impartial conversion made without departing from the spirit and scope of the invention and amendment, all should contain in the scope of the present invention.
