Description

Technical Field

[0001] This utility model relates to the field of tempered glass technology, and in particular to an energy-saving and heat-insulating tempered glass. Background Technology

[0002] Tempered glass is actually a type of prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the load-bearing capacity and enhancing the glass's resistance to wind pressure, temperature changes, and impact.

[0003] Most existing tempered glass has a double-layer hollow structure, with the middle layer either evacuated or filled with inert gas for heat insulation. It is sealed with a sealing material to reduce the gas leakage rate and extend its service life. Although the sealing material itself is not permeable to water, capillary action may cause moisture to be drawn into the air layer along the micro-channels of the sealing material. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an energy-saving and heat-insulating tempered glass. The first tempered glass and the second tempered glass are connected to the inside of the second inner frame by the first inner frame, and the edges are sealed with sealant to reduce the ingress of moisture and extend the service life of the glass. The silica gel drying layer absorbs the moisture that enters due to capillary action to keep it dry and prevent water vapor from forming inside the glass.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An energy-saving and heat-insulating tempered glass includes two outer frames. A first tempered glass is disposed on the inner wall of the upper outer frame, and a first inner frame is fixedly connected to the bottom end of the first tempered glass. A second tempered glass is disposed on the inner wall of the lower outer frame, and a second inner frame is fixedly connected to the top end of the second tempered glass. The outer wall of the first inner frame is snapped into the inner wall of the second inner frame.

[0007] Furthermore, both the first tempered glass and the second tempered glass have a low-emissivity film on their outer ends to reflect some of the solar radiation heat.

[0008] Furthermore, a PVB layer is fixedly connected to the inner side of the first tempered glass and the second tempered glass corresponding to the inner side of the first inner frame and the second inner frame, and a silicone drying layer is fixedly connected to the inner side of the PVB layer.

[0009] Furthermore, an inert gas is filled between two adjacent silica gel drying layers to isolate heat transfer.

[0010] Furthermore, the first tempered glass and the second tempered glass are provided with sealant at their inward ends corresponding to the outer sides of the first inner frame and the second inner frame, in order to seal the inert gas inside the first inner frame and the second inner frame.

[0011] Furthermore, the outer wall of the sealant is tightly adhered to the inner wall of the outer frame, further sealing off inert gases and reducing the ingress of moisture.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the first tempered glass and the second tempered glass are connected to the inside of the second inner frame by the first inner frame, and the edges are sealed with sealant to reduce the entry of moisture and extend the service life of the glass. The silicone drying layer absorbs the moisture that enters due to capillary action to keep it dry and prevent water mist from forming inside the glass.

[0014] 2. In this utility model, the low-emissivity film coated on the outer walls of the first tempered glass and the second tempered glass has high visible light transmittance and low infrared reflectivity, which can effectively prevent indoor heat from being lost to the outside through the window, while reflecting some of the solar radiation heat. Combined with the PVB layer, it can absorb sound waves and improve the sound insulation effect of the glass. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4 This utility model provides an embodiment of an energy-saving and heat-insulating tempered glass, comprising two outer frames 1. A first tempered glass 3 is disposed on the inner wall of the upper outer frame 1, and a first inner frame 6 is fixedly connected to the bottom end of the first tempered glass 3. A second tempered glass 5 is disposed on the inner wall of the lower outer frame 1, and a second inner frame 7 is fixedly connected to the top end of the second tempered glass 5. The outer wall of the first inner frame 6 is snapped into the inner wall of the second inner frame 7. Both the first tempered glass 3 and the second tempered glass 5 have a low-emissivity film 2 at their outward-facing ends to reflect some of the solar radiation heat. PVB layer 9 is fixedly connected to the inner side of the first inner frame 6 and the second inner frame 7 at the inner end of the glass 5. Silica gel drying layer 8 is fixedly connected to the inner end of the PVB layer 9. Inert gas is filled between two adjacent silica gel drying layers 8 to isolate heat transfer. Sealant 4 is provided on the outer side of the first inner frame 6 and the second inner frame 7 at the inner end of the first tempered glass 3 and the second tempered glass 5 to seal the inert gas inside the first inner frame 6 and the second inner frame 7. The outer wall of the sealant 4 is tightly adhered to the inner wall of the outer frame 1 to further seal the inert gas and reduce moisture ingress.

[0023] Specifically, the first inner frame 6 at the bottom of the first tempered glass 3 is inserted into the second inner frame 7 at the top of the second tempered glass 5, forming a closed space filled with inert gas. This improves the heat insulation performance of the glass and ensures that the space has the same air pressure as the outside, preventing external moisture from entering the space due to pressure difference. Inside this space, a silica gel drying layer 8 and a PVB layer 9 are also installed. The silica gel drying layer 8 absorbs moisture that enters due to capillary action, keeping the glass dry and preventing water vapor from forming inside. The PVB layer 9 absorbs sound waves, improving the sound insulation effect of the glass. After the first tempered glass 3 and the second tempered glass 5 are combined, through... The sealant 4 is used to seal and connect the edges, fixing the first tempered glass 3 and the second tempered glass 5 and reducing the possibility of inert gas leakage from the inside, thus extending the service life of the glass. Then, the whole assembly is snapped into the two outer frames 1 and fixed with bolts to protect the sides of the first tempered glass 3 and the second tempered glass 5, while further improving the overall sealing performance of the glass. The low-emissivity film 2 coated on the outer wall of the first tempered glass 3 and the second tempered glass 5 has high visible light transmittance and low infrared reflectivity, which can effectively prevent indoor heat from being lost to the outside through the window, while reflecting some of the solar radiation heat.

[0024] Working principle: When external solar radiation shines on the glass, it is reflected by the low-emissivity film 2, reducing heat transfer into the room. When heat is transferred between the two sides of the glass, it is affected by the inert gas layer between the first tempered glass 3 and the second tempered glass 5, reducing heat transfer. The first tempered glass 3 and the second tempered glass 5 are connected to the second inner frame 7 by the first inner frame 6 and sealed with sealant 4 to reduce inert gas leakage and moisture ingress, extending the service life of the glass. Moisture that enters due to capillary action is absorbed by the silica gel drying layer 8. The outer frame 1 of the outer wall of the first tempered glass 3 and the second tempered glass 5 can further seal and protect the sides of the first tempered glass 3 and the second tempered glass 5.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
