Description

Technical Field

[0001] The utility model belongs to the technical field of perspective films, and in particular relates to a heat-insulating and energy-saving one-way perspective film. Background Art

[0002] One-way vision film (also called one-way film, mirror film, etc.) refers to a film that is pasted on the glass to make the glass have a high reflectivity for visible light. The one-way vision film can achieve the effect that when the outdoor is brighter than the indoor, the one-way vision glass is similar to an ordinary mirror. The outdoor scenery cannot be seen from the outdoor, but the outdoor scenery can be seen clearly from the indoor. Now the one-way vision film is widely used in home life glass film.

[0003] The existing one-way perspective film has poor insulation effect against ultraviolet rays and heat when in use, resulting in excessively high indoor temperatures under long-term exposure. At the same time, at night, the outdoor light intensity is weaker than the indoor light intensity, resulting in clear observation of indoor conditions from the outside, and poor privacy. Summary of the invention

[0004] The utility model provides a heat-insulating and energy-saving one-way perspective film, which aims to solve the problem that the existing one-way perspective film has poor UV protection and heat insulation when in use, and at the same time, the outdoor light intensity is weaker than the indoor light intensity at night, resulting in indoor conditions being observable from the outdoors and poor privacy.

[0005] An embodiment of the utility model provides a heat-insulating and energy-saving one-way perspective film, comprising a window frame, a transparent window panel hinged on the side of the window frame, a perspective film body arranged on the window frame, the perspective film body consisting of a metal film layer, an anti-ultraviolet layer, a heat-insulating layer, a first polarizing film layer, an adhesive layer and a protective layer, the metal film layer being located on the outermost side, the inner side of the metal film layer is fixedly connected with the anti-ultraviolet layer, the inner side of the anti-ultraviolet layer is fixedly connected with the heat-insulating layer, the inner side of the heat-insulating layer is fixedly connected with the first polarizing film layer, the inner side of the first polarizing film layer is fixedly connected with the adhesive layer, the outer side of the adhesive layer is fixedly connected with the protective layer, and the second polarizing film layer is fixedly connected with the transparent window panel.

[0006] Furthermore, the metal film layer is a silver-plated film manufactured by chemical vapor deposition.

[0007] By adopting the above technical solution, the metal film layer adopts a silver-plated film made by chemical vapor deposition, which plays a role in reflecting light and facilitates the one-way perspective function.

[0008] Furthermore, the anti-ultraviolet layer is a spreadable nano coating.

[0009] By adopting the above technical solution, the anti-ultraviolet layer is a spreadable nano-coating, which is convenient for absorbing a large amount of ultraviolet rays in the light.

[0010] Furthermore, the thermal insulation layer is a low-emissivity (Low-E) coating.

[0011] By adopting the above technical solution, the heat insulation layer is a low-emissivity (Low-E) coating, which can effectively isolate heat.

[0012] Furthermore, the adhesive layer adopts polyurethane (PU) glue.

[0013] By adopting the above technical solution, the adhesive layer adopts polyurethane (PU) glue, which has good adhesive performance and is not easy to fall off.

[0014] Furthermore, the protective layer adopts an aluminum oxide or silicon dioxide coating.

[0015] By adopting the above technical solution, the protective layer adopts an aluminum oxide or silicon dioxide coating, which can greatly improve the wear resistance of the surface and enhance the protection ability.

[0016] Furthermore, the transmission directions of the first polarizing film layer and the second polarizing film layer are perpendicular to each other.

[0017] By adopting the above technical solution, when the outdoor light intensity is weaker than the indoor light intensity at night, the transparent window panel is closed so that the light can be isolated because the transmission directions of the first polarizing film layer and the second polarizing film layer are perpendicular to each other, and thus the light cannot be transmitted from the outside to the inside or from the inside to the outside, thereby greatly improving the privacy of the room.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model provides a first polarizing film layer and a second polarizing film layer. When the outdoor light intensity is weaker than the indoor light intensity at night, the transparent window panel is closed, so that the light can be isolated because the transmission directions of the first polarizing film layer and the second polarizing film layer are perpendicular to each other. As a result, the light cannot be transmitted from the outside to the inside or from the inside to the outside, thereby greatly improving the privacy of the room.

[0020] 2. The utility model can greatly improve the ability to block ultraviolet rays in light by providing an anti-ultraviolet layer, a heat-insulating layer and a protective layer, and can effectively provide a heat-insulating effect and prevent the surface from being damaged.

The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 , Figure 2The utility model embodiment proposes a heat-insulating and energy-saving one-way perspective film, comprising a window frame 1, a transparent window panel 2 is hinged on the side of the window frame 1, a perspective film body is arranged in the window frame 1, and the perspective film body consists of a metal film layer 3, an anti-ultraviolet layer 4, a heat-insulating layer 5, a first polarizing film layer 6, an adhesive layer 7 and a protective layer 8, the metal film layer 3 is located at the outermost side, the inner side of the metal film layer 3 is fixedly connected with the anti-ultraviolet layer 4, the inner side of the anti-ultraviolet layer 4 is fixedly connected with the heat-insulating layer 5, the inner side of the heat-insulating layer 5 is fixedly connected with the first polarizing film layer 6, the inner side of the first polarizing film layer 6 is fixedly connected with the adhesive layer 7, and the adhesive layer A protective layer 8 is fixedly connected to the outer side of 7, a second polarizing film layer 9 is fixedly connected to the transparent window plate 2, the metal film layer 3 adopts a silver-plated film manufactured by chemical vapor deposition, which plays a role of reflecting light, so as to facilitate the one-way perspective function, the anti-ultraviolet layer 4 is a spreadable nano-coating, which is convenient for absorbing a large amount of ultraviolet rays in the light, the heat insulation layer 5 is a low-radiation Low-E coating, which can well isolate heat, the adhesive layer 7 adopts polyurethane PU glue, which has good adhesive performance and is not easy to fall off, and the protective layer 8 adopts aluminum oxide or silicon dioxide coating, which can greatly improve the wear resistance of the surface and improve the protection ability.

[0029] Reference Figure 3 The transmission directions of the first polarizing film layer 6 and the second polarizing film layer 9 are perpendicular to each other. When the outdoor light intensity is weaker than the indoor light intensity at night, the transparent window panel 2 is closed so that the light can be isolated because the transmission directions of the first polarizing film layer 6 and the second polarizing film layer 9 are perpendicular to each other. As a result, the light cannot be transmitted from the outside to the inside or from the inside to the outside, which greatly improves the privacy of the room.

[0030] The specific implementation method is as follows: when used during the day, the light intensity outdoors is higher than the light intensity indoors, so that the user can clearly see the outdoors from indoors, and the situation indoors cannot be seen from outdoors, and a one-way perspective effect can be achieved. When used at night, the light intensity outdoors is lower than the light intensity indoors, so that the situation indoors can be clearly seen from outdoors, but people indoors can only see the reflection of the indoors and cannot see the outdoors. Therefore, at night, the privacy of indoor users is greatly reduced. At this time, the user closes the transparent window panel 2, so that a second polarizing film layer 9 appears on the front side of the first polarizing film layer 6 that was originally able to transmit light, and then the transmission directions of the first polarizing film layer 6 and the second polarizing film layer 9 (i.e., the directions in which light is allowed to pass) are perpendicular to each other. Then, the light transmitted by the first polarizing film layer 6 will be completely absorbed or reflected by the second polarizing film layer 9, thereby achieving light isolation, and then at night, the situation outdoors cannot be seen from indoors, and at the same time, the situation indoors cannot be seen from outdoors, which greatly improves the privacy of the user.
