Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat-insulating glass, in particular to a heat-insulating glass. Background Art
[0002] In the field of architecture, glass materials are widely used due to their high transparency and aesthetics. However, with global warming and people's increasing requirements for energy conservation and environmental protection, the thermal insulation performance of traditional glass materials has gradually failed to meet the needs of modern life. Especially in hot summers and cold winters, the temperature difference between indoors and outdoors is large, and traditional glass cannot effectively block the transfer of heat, resulting in excessively high or low indoor temperatures, which not only increases the energy consumption of air conditioning and heating equipment, but also reduces people's living and travel comfort.
[0003] In order to improve the thermal insulation performance of glass, domestic and foreign researchers have conducted a lot of exploration and practice. At present, there are many glass products with thermal insulation functions on the market, such as hollow glass, coated glass, LOW-E glass, etc. These products have improved the thermal insulation performance of glass to a certain extent, but there are still some shortcomings. For example, although hollow glass has a good thermal insulation effect, its production cost is high, and once the seal fails, the thermal insulation performance will be greatly reduced; although coated glass can reflect part of the solar radiation, its light transmittance is poor, and the coating layer is easy to fall off after long-term use; although LOW-E glass has good comprehensive performance, it is expensive and difficult to popularize and apply.

[0022] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0023] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure. Example
[0024] like Figure 1-3 As shown, the utility model provides a heat-insulating glass, comprising:
[0025] A surface glass 1, wherein a tin oxide film 8 is provided on the surface of the surface glass 1;
[0026] An inner layer of glass 2, wherein an inorganic salt layer 9 is provided in the inner layer of glass 2;
[0027] The interlayer 3 is filled with an inert gas.
[0028] The tin oxide film 8 is located on the surface glass 1, and its main function is to increase the hardness and heat resistance of the glass. During the melting process of the glass, the tin oxide reacts with other components to form hard crystals, which can enhance the hardness and flexural strength of the glass and reduce the possibility of scratches on the glass surface. At the same time, it can also improve the high temperature resistance of the glass, enhance the thermal shock resistance and temperature change resistance.
[0029] The inorganic salt layer 9 is located in the inner glass 2. As a part of the heat-insulating glass, its main function is to cooperate with the inert gas in the interlayer 3 to improve the heat-insulating effect. The inorganic salt layer 9 has heat-reflecting and heat-absorbing properties, and can reduce the heat transfer through the glass.
[0030] The inert gas in the interlayer 3 mainly plays the role of heat insulation. The inert gas can reduce the U value of the glass, thereby enhancing the heat insulation performance. In winter, it helps to keep heat energy indoors; in summer, it can block heat from entering the room, thereby reducing the energy consumption of indoor cooling and achieving excellent energy-saving effects.
[0031] Filling with inert gas can also reduce condensation inside the glass, reduce the possibility of condensation and frost, and improve indoor comfort. Inert gas can slow down heat convection in insulating glass, thereby improving sound insulation and noise reduction performance, making the indoor environment quieter. Filling with inert gas can also reduce the internal and external pressure difference, maintain pressure balance, reduce the risk of glass breakage caused by pressure difference, and extend the service life of the material.
[0032] The inorganic salt layer 9 contains at least one of phosphate and silicate, and absorbs a large amount of near-infrared light while absorbing visible light.
[0033] Phosphates and silicates can absorb near-infrared light in large quantities, which greatly reduces the amount of heat transferred through the glass, thereby significantly improving the overall thermal insulation performance of the insulating glass. This helps to lower indoor temperatures in the summer, reduce the use of equipment such as air conditioners, and reduce energy consumption.
[0034] Wherein, the inert gas includes at least one of argon, krypton and xenon.
[0035] Argon, krypton and xenon have extremely low thermal conductivity, and they can effectively slow down the conduction of heat in the interlayer 3. By filling these gases, the overall heat transfer coefficient (U value) of the insulating glass can be significantly reduced, thereby improving its thermal insulation performance.
[0036] In double-layer or multi-layer insulating glass, the gas in the interlayer 3 can slow down or eliminate the thermal convection phenomenon caused by temperature difference. Thermal convection is a main way of heat transfer. By filling inert gas, its convection effect can be significantly reduced, thereby further improving the thermal insulation effect.
[0037] Insulated glass filled with inert gas is less likely to produce sharp fragments when broken, thus improving safety in use. This is because the inert gas can slow down the splashing speed of glass fragments and reduce the risk of injury to personnel.
[0038] Argon, krypton and xenon are chemically stable and are not easy to react with other substances, so the stability and thermal insulation performance of the thermal insulation glass interlayer 3 can be maintained for a long time.
[0039] See also Figure 1 A hydrophobic layer 4 is provided on the outer side of the surface glass 1 and the inner side of the inner glass 2.
[0040] The hydrophobic surface has excellent anti-fouling properties. Water droplets are not easy to accumulate on the surface. They can roll off quickly to carry away dirt and keep the glass surface clean.
[0041] The hydrophobic layer 4 can effectively prevent water molecules in the air from gathering into water mist on the glass surface, keeping the glass clear and transparent in a humid environment or an environment with a large temperature difference.
[0042] The glass equipped with the hydrophobic layer 4 has a self-cleaning function. When rain or clean water falls on the glass surface, it can quickly condense into water droplets and roll down, while taking away the dirt on the surface, reducing the need for manual cleaning.
[0043] The hydrophobic layer 4 is provided on the curtain wall and glass of the high-rise building, which can greatly reduce the cleaning frequency and maintenance cost, and also avoid the danger of high-altitude operation.
[0044] See also Figure 1 , Figure 2 and Figure 3 The outer edges of the surface glass 1 and the inner glass 2 are respectively provided with a first convex edge 5 and a second convex edge 6 , and the surface glass 1 and the inner glass 2 sandwich the interlayer 3 .
[0045] The provision of the first flange 5 and the second flange 6 can increase the strength and rigidity of the glass edge, thereby improving the stability of the entire insulating glass structure. This design helps to prevent the glass from being deformed or damaged when subjected to external forces.
[0046] The convex edge design enables the surface glass 1 and the inner glass 2 to form a tighter sealing structure when sandwiching the interlayer 3, which helps to prevent air, moisture or other impurities from entering the interlayer 3, keeping the interlayer 3 dry and clean, thereby improving the thermal insulation performance and service life of the insulating glass.
[0047] During use, the glass may be slightly deformed or displaced due to changes in environmental factors such as temperature and humidity. The convex edge design can prevent the dislocation or offset between the surface glass 1 and the inner glass 2 to a certain extent, and maintain the stability of the insulating glass structure.
[0048] See also Figure 1 , Figure 2 and Figure 3 The first convex edge 5 on the surface glass 1 is provided with a first slot 51, and the interlayer 3 is provided with a first latch 31, and the surface glass 1 and the interlayer 3 are connected by latches.
[0049] Through the precise fit of the first slot 51 and the first pin 31, a stable connection structure is formed between the surface glass 1 and the interlayer 3. This connection method can effectively prevent the glass from being displaced or deformed due to external factors (such as wind pressure, temperature difference, etc.) during use, thereby ensuring the overall stability of the insulating glass.
[0050] The tight combination of the latch and the slot helps to form a tight sealing structure to prevent air, moisture or other impurities from entering the interlayer 3, which not only keeps the interlayer 3 dry and clean, but also improves the thermal insulation performance and service life of the insulating glass.
[0051] See also Figure 1 , Figure 2 and Figure 3 The second convex edge 6 on the inner glass 2 is provided with a second latch 61, the interlayer 3 is provided with a second slot 32, and the inner glass 2 and the interlayer 3 are connected by latches.
[0052] Through the close connection between the second pin 61 and the second slot 32, a stable connection is formed between the inner glass 2 and the interlayer 3. This connection method ensures the overall structural strength of the insulating glass, enabling it to withstand various external forces (such as wind pressure, stress caused by temperature changes, etc.), thereby maintaining long-term stability and safety.
[0053] The tight fit between the latch and the slot helps to form an efficient sealing structure, effectively preventing air, moisture or other impurities from entering the interior of the interlayer 3. This not only keeps the interlayer 3 dry and clean, prevents condensation or mildew inside, but also ensures that the insulating glass maintains good thermal insulation performance for a long time.
[0054] See also Figure 1 A steel mesh 7 is arranged inside the surface glass 1 and the inner glass 2.
[0055] The presence of the steel mesh 7 significantly enhances the strength and stability of the glass. When subjected to external impact or pressure, the steel mesh 7 can effectively prevent the glass from breaking or deforming, reducing the risk of glass shattering or splashing. This feature is crucial for building safety, especially in situations where it needs to withstand greater wind pressure or unexpected impact.
[0056] Even if the glass breaks after a strong impact, the wire mesh 7 can fix the fragments in place to prevent the fragments from scattering, thereby greatly reducing the risk of personal injury.
[0057] The steel wire mesh 7 not only increases the strength of the glass, but also helps to improve the heat insulation and sound insulation effect. It can effectively block the heat and noise from the outside, providing a more comfortable and quiet environment indoors.
[0058] The addition of the steel mesh 7 makes the glass more stable in extreme situations such as fire, and is not easy to break or deform, thereby enhancing the fireproof performance of the glass to a certain extent.
