Description
Technical Field
The application relates to a hollow heat-insulating glass door and window in the field of energy-saving buildings, in particular to a substrate of an inner suspension film which can be used as the inner suspension film door and window and a preparation method thereof.
Background
The energy-saving building field generally adopts hollow glass doors and windows to isolate indoor and outdoor temperature differences and realize light transmission. The basic principle of the energy-saving door and window is that one or more layers of transparent plastic films are added in the inner cavity of the hollow glass, and the inner cavity of the hollow glass is isolated into a plurality of mutually independent spaces through the plastic films, so that the temperature difference between the inside and the outside of the hollow glass can not realize convection, thereby reducing the weight of the structure and simultaneously having excellent energy-saving effect.
The inner suspension film for the inner suspension film door and window is usually made of plastic film with better heat resistance and insulation effects. For example, a plastic film such as a window film commonly used in the field of ordinary buildings may be used as the inner suspension film. For example, in prior art CN 112659705A previously filed by the applicant, a substrate for window film is disclosed, on the surface of which one or more refractive layers, metal oxide layers, metal sputtering layers, etc. may be attached by coating or sputtering, etc. on the substrate, so as to obtain window films of different functions and colors.
Similarly, in the background section of this prior art mentioned, in prior art CN106435497a previously filed by the applicant, a gold low-emissivity energy-saving window film and a method for preparing the same are disclosed, which window film is gold in sunlight. The gold low-radiation energy-saving window film in the prior art has the advantages that infrared light is reflected by the double silver alloy layers and is high with three layersThe refraction layer forms a refractive index matching relationship, and through the matching of thickness parameters, the color of the refraction layer is golden under sunlight, so that the refraction layer has an excellent visual effect. Meanwhile, the golden window film also has excellent light transmission, heat insulation and oxidation resistance, long service life and easy production. The window film materials of the prior art described above generally require the formation of a metal oxide layer and a silver-containing metal layer on the surface of a substrate. For example, CN106435497A describes that the golden window film is: a flexible transparent PET substrate layer; from Si 3 N 4 A first high refractive index layer formed; a first metal oxide layer composed of ZnO and Al; a first silver alloy layer composed of 98% Ag and 2% Pd; a first barrier layer composed of Si; from Nb 2 O 5 A second high refractive index layer; forming a second metal oxide layer from ZnO and Al; a second silver alloy layer composed of 98% Ag and 2% Pd; forming a second barrier layer from Si; from Si 3 N 4 And a third high refractive index layer is formed. The prior art particularly indicates that the color of the golden window film and the functions of effectively reflecting infrared rays and ultraviolet rays and improving the heat insulation performance of the window film are mainly brought by a compact silver alloy layer, the compactness of the silver alloy layer can be realized by a ZnO: al metal oxide layer with a thickness of a few nanometers, and the ZnO: al layer with a thickness of a few nanometers can promote the growth of a subsequent silver alloy layer to enable the subsequent silver alloy layer to grow into a continuous compact structure as soon as possible, so that the thickness of the subsequent silver alloy layer is obviously reduced, and the light transmittance of the window film is improved.
For an inner suspended film door and window, the thermal expansion coefficient of an inner suspended film clamped between two pieces of glass is larger than that of the glass, so that the inner suspended film tends to be gradually loosened in the use process, and the loosened inner suspended film is inconsistent in the refraction direction of light, so that a scene outside the observation room through the glass door and window can generate visual deformation due to refraction. In order to maintain the parallel transmission of light rays to avoid visual distortion, the inner suspension film needs to be installed in a tensioned state between the hollow glasses. The inner suspension film in a tensioned state is deformed in the lateral direction. However, the ZnO film layer formed by growth in a magnetron sputtering mode has the characteristic of high vertical crystallization, is very sensitive to transverse deformation, and is easy to generate longitudinal cracks under the action of transverse tensile force, so that the metal silver film layer attached to the surface of the ZnO film layer is cracked, and the light transmittance and the reflection performance of the window film are affected. Therefore, the window film with the silver-containing metal layer in the prior art can be adhered on a flat and firm glass surface for use, and is difficult to apply to the field of inner suspension films.

Detailed Description
For a clearer understanding of technical features, objects, and effects of the present application, a specific embodiment of the present application will be described with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals.
As shown in fig. 1, the application provides an inner suspension film door and window, which at least comprises a tensioning frame 3 clamped between two layers of glass 1 and used for tensioning an inner suspension film 2, wherein the tensioning frame 3 and the inner suspension film 2 tensioned on the tensioning frame can be installed between the two layers of glass 1 as an independent component, so that the tensioning problem of the inner suspension film is not needed to be considered when the glass door and window is installed, and the installation complexity is reduced.
Further, in the illustrated embodiment, both sides of the tension frame 3 may be bonded between the two layers of glass 1 by spacer bars 4. For example, the spacer 4 may be an existing composite butyl aluminum spacer, butyl rubber for adhesion is provided on two sides of the spacer 4, and a molecular sieve for adsorbing water vapor may be disposed in a hollow structure inside the spacer 4. The inner suspension film door and window is only provided with one layer of inner suspension film 2, and can be deformed into a structure with two or more layers of inner suspension films by adding the tensioning frame 3 according to the requirement.
The inner suspension film 2 is made of a plastic film with good heat-resistant and insulating effects, and needs to be tensioned between the hollow glass to keep light rays to transmit in parallel to avoid visual deformation.
Fig. 2 shows a schematic view of the thermal insulation principle of an inner suspension film according to an embodiment of the present application, illustrating that the inner suspension film 2 includes an inner suspension film substrate 21 and at least one silver alloy layer 22 formed on the inner suspension film substrate 21. In one embodiment, silver alloy layer 22 may be formed from 98% Ag, 2% Pd on the surface of overhang film substrate 21 by single spin cathode, direct current reactive magnetron sputtering. The silver alloy layer 22 can realize the functions of high visible light transmission and reflection to most of infrared rays so as to effectively isolate heat.
Fig. 3 further shows a schematic cross-sectional structure of an inner suspension film substrate according to an embodiment of the present application, the outermost silver alloy layer 22 being shown in broken lines for ease of understanding. As shown in the embodiment of the figure, the inner suspension film substrate 21 of the present application comprises a polyester film 211, at least one ZnO: al layer 213 (aluminum-doped zinc oxide layer, aluminum content not more than 2 wt%) is formed on the outermost side of the polyester film 211 facing the silver alloy layer 22, and an adhesion layer 212 is formed between the ZnO: al layer 213 and the outermost side of the polyester film 211. The ZnO: al layer 213 may be formed on the surface of the adhesion layer 212 by means of single-rotation cathode, direct-current reactive magnetron sputtering.
As described above, the ZnO-Al layer can promote the growth of the subsequent silver alloy layer to make the subsequent silver alloy layer grow into a continuous compact structure as soon as possible, thereby remarkably reducing the thickness of the subsequent silver alloy layer and improving the light transmittance of the window film. However, the defect of the ZnO/Al layer is that the film layer is crystallized by growing along the vertical direction of the film, and cracks are generated in the transversely stretched state. The inventors found that the probability of crack generation in the case of extreme wrinkles can be reduced by reducing the thickness of the ZnO: al layer, but that the growth rate of the silver alloy layer on the ZnO: al layer and the compactness of the film layer can be simultaneously reduced.
According to the same technical conditions as disclosed in CN106435497A cited in the background art, a ZnO/Al layer of 3nm to 6nm thickness was formed on a polyester film. The test shows that at a bending diameter of 5 mm, the ZnO: al layer does not substantially crack, but at 10% elongation of the inner suspension film, the ZnO: al layer still has significant cracks. Of course, if a thicker silver alloy layer is formed on the surface of the ZnO: al layer, these cracks can be masked to some extent because the silver alloy layer has a good ductility, and no cracks are revealed when the silver alloy layer is surface-inspected. In this case, there is a contradiction that the thickness of the ZnO: al layer may be reduced in order to reduce cracks, which may result in a reduction in the growth rate of the silver alloy layer, but a thicker silver alloy layer thickness is required to mask the inner layer cracks, and further extension of the growth time of the silver alloy layer is required, thereby further increasing the production cost.
In order to overcome the contradiction, the application arranges the adhesion layer 212 on the inner side of the ZnO Al layer 213 to be matched with the ZnO Al layer 213 through the adhesion layer 212, thereby reducing the surface cracks of the inner suspension film base material and the silver alloy layer on the inner suspension film base material, improving the light transmission performance, improving the growth speed of the silver alloy layer and reducing the processing time and the production cost under the condition of not increasing the thickness of the ZnO Al layer.
Fig. 2 shows only a schematic structure of one specific embodiment of the inner suspension film substrate of the present application, and those skilled in the art will appreciate that many modifications can be made to the inner suspension film structure of the present application while achieving the above-described technical effects. For example, a plurality of silver alloy layers 22 and the like may be formed on the inner suspension film base material 21 as in the related art.
Specifically, the adhesion layer 212 is cured by coating on the outer surface of the polyester film 211, and the adhesion layer 212 may be prepared from the following raw materials in parts by weight: 6-8 parts by weight of polydimethylsiloxane; 1-5 parts of polyurethane; 15-30 parts by weight of vinyl trimethoxy silane; 80-120 parts by weight of isopropanol; 10-20 parts of polyethylene glycol; 1-5 parts of zinc oxide; 0.1-0.5 parts by weight of alumina; 0.1 to 0.5 part by weight of magnesium sulfate.
In a specific embodiment, the inner suspension film substrate may be prepared by the steps of the following method.
Firstly, uniformly mixing 10-20 parts by weight of polyethylene glycol and 60-80 parts by weight of isopropanol, and respectively adding 1-5 parts by weight of zinc oxide, 0.1-0.5 part by weight of aluminum oxide and 0.1-0.5 part by weight of magnesium sulfate into the mixed solution, mixing and stirring for 30-60 minutes to prepare the component A.
Then, 6-8 parts by weight of polydimethylsiloxane, 1-5 parts by weight of polyurethane, 15-30 parts by weight of vinyltrimethoxysilane and 20-40 parts by weight of isopropanol are mixed, mixed and stirred for 20-30 minutes, and the viscosity is 200-300 centipoise, so that the component B is prepared.
The adhesive layer 212 is prepared by mixing and stirring the A component and the B mixed component for 20-30 minutes, then coating the surface of at least one side of the polyester film by spin coating or spray coating, and curing at 120-130 ℃ for 2-3 hours.
On the prepared adhesion layer 212, a ZnO: al layer 213 was formed by means of single-rotation cathode, direct-current reaction magnetron sputtering, thereby preparing the inner suspension film base material 21 of the present application.
Further, at least one silver alloy layer 22 can be formed on the inner suspension film substrate 21 by means of single-rotation cathode and direct-current reaction magnetron sputtering, so as to prepare and obtain the inner suspension film 2 applicable to the application.
Examples 1 to 3
The adhesive layers 212 were prepared on the surfaces of the polyester films 211, respectively, based on the above preparation methods, according to the weight parts of the raw materials in the following table. The polyester film 211 is a PET film with a light transmittance of 89% and a thickness of 25 μm.
Examples 4 to 6
On the adhesion layers prepared in examples 1 to 3, znO Al layer 213 (aluminum content 1.5wt%, znO content 98.5 wt%) and silver alloy layer 22 (98 wt% Ag, 2wt% Pd) were formed, respectively, by magnetron sputtering in this order, corresponding to examples 4 to 6.
Comparative examples D1 to D3
Referring to the preparation steps of examples 1 to 3, the adhesive layers 212 for comparison were prepared on the surfaces of the polyester films 211, respectively, in the proportions by weight of the raw materials of the following table. The polyester film 211 was a PET film having a light transmittance of 89% and a thickness of 25. Mu.m, corresponding to comparative examples D1 to D3.
Comparative examples D4 to D6
Referring to the preparation steps of examples 1 to 3, the adhesive layers 212 for comparison were prepared on the surfaces of the polyester films 211, respectively, in the proportions by weight of the raw materials of the following table. The polyester film 211 was a PET film having a light transmittance of 89% and a thickness of 25. Mu.m, corresponding to comparative examples D4 to D6.
Comparative examples D7 to D12
On the adhesion layers prepared in comparative examples D1 to D6, znO was formed as a comparison by magnetron sputtering, respectively, an Al layer (aluminum content 1.5wt%, znO content 98.5 wt%) and a silver alloy layer 22 (98 wt% Ag, 2wt% Pd) were formed in this order, corresponding to comparative examples D7 to D12.
| Comparative example | D7 | D8 | D9 | D10 | D11 | D12 |
| ZnO: al layer thickness nm | 3 | 5 | 6 | 3 | 5 | 6 |
| Silver alloy layer thickness nm | 10 | 13 | 15 | 10 | 13 | 15 |
| Average growth rate nm/min of silver alloy layer | 0.1 | 0.15 | 0.05 | 0.5 | 0.51 | 2.5 |
Through the above comparative experiments, the average growth rate of the silver alloy layer is subject to a larger image of the oxide composition, especially the image of the growth rate of the very small amount of magnesium sulfate is maximized.
The performance parameters of the respective adhesive layer skin layers of the polyester films of examples 1 to 6 and comparative examples D1 to D12 were measured, respectively.
As can be seen from comparison of various performance parameters, the surface crack of the inner suspension film substrate can be obviously reduced by matching the ZnO: al layer with the additional layer arranged on the inner side, the light transmittance is improved, meanwhile, the growth speed of the silver alloy layer is improved under the condition that the thickness of the ZnO: al layer is not increased, and the processing time and the production cost are reduced.
In addition, excessive addition of metal oxide can reduce the transparency of the film, so that cracks are easily generated on the surface of the ZnO-Al layer, and the surface quality of the silver alloy layer and the product quality are further influenced. Further tests show that the addition of a small amount of polyurethane is beneficial to maintaining the bonding strength of the silver alloy layer and the ZnO-Al layer and avoiding layering of the silver alloy layer and the ZnO-Al layer.
In order to more clearly understand the stretching and tensioning state of the inner hanging film, the structure of the inner hanging film door and window of the present application will be further described in detail with reference to fig. 4 to 8.
Because the tensioning operation of the inner suspension film in the prior art is very complicated, four sides of the inner suspension film need to be respectively clamped on a plurality of elastic elements during installation, and in order to prevent the inner suspension film from wrinkling, the tensioning force needs to be locally and repeatedly adjusted. In addition, the inner suspension film repeatedly expands with heat and contracts with cold in the long-term use process, the tension difference can lead the film to be extruded to local positions to form folds, the permeability of the glass door and window can be influenced, and the outdoor scenery can be observed to generate visual deformation due to refraction.
In order to solve the above-mentioned problems, as can be seen in the exploded perspective view of the tension frame 3 shown in fig. 4, the four sides of the inner suspension film 2 of the present application are wound on four reels 20, respectively, and both ends of the four reels 20 are mounted inside the tension frame 3 through elastic tensioners 5, respectively.
In one embodiment illustrated, in order to facilitate tensioning of the inner suspension film 2 while exposing both ends of the roll 20, the inner suspension film 2 is rectangular with four corners cut away, so that the four sides of the inner suspension film 2 are narrower in width near the edge positions, and thus when wound on the roll 20, the thicker the winding thickness of the inner suspension film 2 on the roll 20 is near the middle of the roll 20, and the thinner the winding thickness of the inner suspension film near both ends of the roll 20 is. That is, the inner suspension film 2 wound around the reel 20 is formed in a spindle shape having a thick middle and thin ends. Therefore, as the inner suspension film 2 is tightly wound on the reel 20, the tension force at the middle position of the inner suspension film 2 is gradually larger than the tension force at the corner position, so that the film stretching relaxation generated by the thermal expansion of the middle suspended inner suspension film can be counteracted. At the same time, the winding edges of the inner suspension film 2 tend to extend toward the two ends with a thinner thickness, thereby naturally eliminating the phenomenon that the film is locally extruded to generate wrinkles.
As can be seen from the stretching process of the inner suspension film of the present application, the middle suspended portion of the inner suspension film is subjected to the greatest stretching extension during use, while the reel portion does not need to be excessively extended, but if the growing thickness of the silver alloy layer is too thin or the compactness of the ZnO: al layer is insufficient during winding around the reel 20, cracks easily occur in the portion adjacent to the reel, and under a long-time stretching state, these cracks easily extend to the middle, so that it is necessary to provide an improvement of the inner suspension film substrate of the present application.
Further, in order to facilitate the winding of the inner suspension film 2 by the spool 20 to generate an even tension, it is preferable that the spool 20 is circular in cross section for winding the middle portion of the inner suspension film 2. In addition, in order to facilitate that the tension force attached to the elastic tensioner 5 after tensioning does not relax, the cross section of the spool 20 for attaching both ends of the elastic tensioner 5 is square, so that the spool 20 is not easily rotated.
According to the tension device, the four edges of the inner suspension film are respectively wound on the four reels, larger tension force can be obtained in the middle of the inner suspension film, the heated relaxation of the inner suspension film is counteracted, and the wrinkles are naturally eliminated through winding, so that only the two ends of the reels are required to be tensioned when the tension device is arranged on a tensioning frame, the tension force does not need to be adjusted one by one for every point on the periphery of the inner suspension film, and the complexity of tensioning operation is greatly reduced.
Further, as shown in fig. 5, the tension frame 3 includes a first frame 31 and a second frame 32 which are provided to be clamped between both sides of the inner suspension film 2, and the elastic tension device 5 is provided inside a cavity formed by the first frame 31 and the second frame 32 being fastened. In the particular embodiment illustrated, two elastic tensioners 5 are provided for each reel 20, so that a total of eight elastic tensioners 5 are provided inside the first 31 and second 32 frames, only six elastic tensioners 5 being shown in fig. 4 due to the shielding from view. Every two elastic tensioning devices 5 are combined into a group, and are connected into a whole through a corner connecting sheet 6, and are arranged at the corner positions of the tensioning frame 3.
The first frame 31 may be formed by splicing four profiles, for example as shown in fig. 5, in which a partial structure of two profiles at one corner position is shown. The four profiles can be connected into a whole by welding or bonding, or two adjacent profiles can be connected into a whole by screws through the corner connecting sheet 6. At this time, the corner connecting piece 6 may connect not only a set of two elastic tensioners 5 at the corner position (by welding or screwing, etc.), but also two profiles. In the embodiment shown in fig. 5, the elastic tensioning device 5 is arranged to be mounted on the first frame 31. Of course, it will be appreciated by those skilled in the art that in an embodiment not shown, the elastic tensioning device 5 may also be provided mounted on the second frame 32.
The second frame 32 may be integrally punched from a metal plate, cast from metal, or injection molded from plastic, as shown in fig. 6. Alternatively, the second frame 32 may be formed by splicing four profiles, as in the first frame 31. Alternatively, the first housing 31 may be integrally formed of metal or plastic, as in the second housing 32. Preferably, the frame body for installing the elastic tensioning device 5 is formed by splicing metal profiles, so that the frame body can have larger supporting strength to adapt to tensioning operation; correspondingly, the other frame body can be made of metal or plastic integrally formed parts.
The second frame 32 may be provided inside the first frame 31 as shown in fig. 1, or in an embodiment not shown, the first frame 31 may be provided inside the second frame 32. In addition, in order to avoid the first frame 31 and the second frame 32 from being separated accidentally, the side edges of the first frame 31 and the second frame 32 may be reinforced by screws (screw holes are shown in the figure, and screws are not shown).
As shown in fig. 5 and 6, the first frame 31 and the second frame 32 have a first annular inner flange 311 and a second annular inner flange 321, respectively, which are located opposite to each other, and the first annular inner flange 311 and the second annular inner flange 321 abut against both side surfaces of the inner suspension film 2, respectively (fig. 1). The inner hanging film 2 is clamped by the first annular inner flange 311 and the second annular inner flange 321 which are abutted against the two side surfaces of the inner hanging film 2, so that the cavities at the two sides of the inner hanging film 2 cannot be communicated with the interiors of the first frame 31 and the second frame 32, the cavities at the two sides of the inner hanging film 2 are well isolated, and heat exchange of air flows in the cavities at the two sides is avoided.
Further, in order to further enhance the insulation effect, in an embodiment not shown, it is preferable that the top of the first annular inner flange 311 and the second annular inner flange 321, which are abutted against the inner hanging membrane 2, are mounted with elastic sealing strips.

Further, the fixing base 51 may be formed by integrally cutting and bending a metal plate, and includes a fixing top plate 511 abutting against a first end of the spring 53, wherein two sides of the fixing top plate 511 are respectively bent to form a fixing guide plate 512, and a bottom of the fixing guide plate 512 is bent to form a mounting plate 513; the fixed top plate 511 is formed with a positioning screw hole 5111 for positioning the spring 53; the mounting plate 513 is formed with a mounting screw hole 5131, and the entire elastic tensioner 5 can be mounted inside the tension frame 3 by a screw penetrating into the mounting screw hole 5131.

After passing through the set screw 5111, the set screw 5112 is threaded at its distal end into the end of the spring 53 so that the spring 53 does not disengage from the set screw 5112 during compression and fails.
The telescopic clamping seat 52 can also be formed by integrally cutting and bending a metal plate, and comprises a movable top plate 521 propping against the second end of the spring 53, wherein a telescopic guide plate 522 is formed by bending the bottom of the movable top plate 521 towards one side of the fixed top plate 511, a hanging plate 523 is formed by bending the tail end of the telescopic guide plate 522 penetrating through a guide opening 5113 at the bottom of the fixed top plate 511, and a return hook plate 524 is formed at the tail end of the hanging plate 523; the end of the square section of the spool 20 is non-rotatably caught in a concave space formed by the telescopic guide plate 522, the hanging plate 523 and the return hook plate 524.
