Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving glass, in particular to a method for configuring ultra-energy-saving hollow glass. Background Art

[0002] As building energy conservation becomes an important factor in building carbon emissions, doors and windows, as the key link in building energy conservation, the balance between energy-saving effect and cost has become the direction pursued by the industry. However, the better the energy-saving effect of the insulating glass, the more complex the configuration is and the cost is relatively high, which is not conducive to large-scale promotion.

[0003] To this end, technicians in this field have proposed an ultra-energy-saving insulating glass configuration method to solve the problems raised by the background technology by designing a hollow glass configuration method with simple configuration, ultra-low insulation coefficient, and unit cost suitable for most building needs. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a super energy-saving insulating glass configuration method. The insulating glass configuration scheme is: 3mm+18Ar+3mmDP+18Ar+3mmDP, 3mm is ordinary tempered white glass, Ar is argon, the argon content in the 18mm hollow cavity is ≥90%, 3mmDP is a special coated glass with multiple screens, and the 3rd and 5th surfaces in the insulating glass configuration are coated surfaces.

[0005] Preferably, the K value of the insulating glass configuration was tested by the National Glass Quality Supervision and Inspection Center in 2017, and the test standard was EN673:2011.

[0006] Preferably, the hollow glass is a three-glass two-cavity product. Due to the reliable insulation coefficient, thermoplastic spacer sealant is used as the effective spacer of the hollow glass. The film is removed from the edge of the 3mmDP glass, and the film removal width is 10mm away from the edge of the glass. The thermoplastic spacer sealant is pressed at 1 / 3 of the sealing line to form two hollow cavities filled with argon gas with a content of more than 90%. After the finished product is completed, a second layer of sealant is sealed with structural glue on the outside of the first layer of sealant, and the production is completed after it is completely cured.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] This ultra-energy-saving insulating glass configuration method achieves a significant reduction in the thermal insulation coefficient while maintaining a low manufacturing cost by optimizing the configuration and manufacturing methods of the insulating glass. The insulating glass configured by this method has been tested by the National Glass Quality Supervision and Inspection Center, and the K value has reached 0.54W / (㎡*K), which is far lower than the requirement of less than 0.8W / (㎡*K) for the heat transfer coefficient of the entire window of ultra-low energy consumption buildings. It meets the needs of most door and window frame materials, greatly reduces the cost of doors and windows, and has good market promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a flow chart of the configuration method of the ultra-energy-saving insulating glass of the present invention. DETAILED DESCRIPTION

[0010] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0011] As attached Figure 1 As shown:

[0012] Embodiment: The present invention provides a method for configuring ultra-energy-saving insulating glass, which is characterized by comprising the following steps:

[0013] S1. The hollow glass structure is 3mm tempered white glass + 18mm argon filling layer + 3mm multi-screen special coated glass (3mmDP) + 18mm argon filling layer + 3mm multi-screen special coated glass (3mmDP), where the argon content in the 18mm hollow cavity is greater than or equal to 90%;

[0014] S2. In the insulating glass configuration, ensure that both sides of the 3mmDP glass (i.e. the 3rd and 5th sides) are coated surfaces;

[0015] S3. Use thermoplastic spacer sealant to form effective spacers in insulating glass and remove film from the edge of 3mmDP glass. The film removal width should be within 10mm from the edge of the glass.

[0016] S4, placing thermoplastic spacer sealant at 1 / 3 of the sealing line to form two hollow cavities and fill them with argon gas;

[0017] S5. Use structural adhesive to perform secondary sealing on the outside of the first sealant to complete the production.

[0018] From the above, it can be seen that by optimizing the configuration and production method of insulating glass, a significant reduction in the thermal insulation coefficient is achieved while maintaining a low manufacturing cost; at the same time, it meets the needs of most door and window frame materials, greatly reduces the cost of doors and windows, and has good market promotion value.

[0019] In contrast, a method for preparing ultra-energy-saving hollow glass is to select high-performance glass sheets, accurately cut and grind them, clean and dry them, and use high-quality sealant to evenly bond and seal the glass sheets to form a dry gas space; finally, inflate and check the sealing to ensure efficient heat insulation and sound insulation, thereby achieving ultra-energy-saving effects.

[0020] Application example: 10 doors and windows are produced by the ultra-energy-saving insulating glass preparation method of the embodiment and the comparative example, and then the doors and windows are tested. The testing method is: the K value is tested by the National Glass Quality Supervision and Inspection Center, and the test standard is EN673:2011; finally, the following table is obtained:

[0021] Group Heat transfer coefficient Configuration (simple / complex) Cost (high / low) Total effective rate (%) Example 0.54W / (㎡*K) or less Simple Low 92.4 Comparative Example 0.60-0.71W / (㎡*K) complex high 83.6

[0022] It can be seen from the above that this embodiment is optimized over the comparative example in terms of configuration, cost and heat transfer coefficient, and has passed the test of the National Glass Quality Supervision and Inspection Center. The heat transfer coefficient of the embodiment reaches 0.54W / (㎡*K), which is much lower than the requirement of less than 0.8W / (㎡*K) for the heat transfer coefficient of the whole window of ultra-low energy consumption buildings, and meets the needs of most door and window frame materials. At the same time, the total efficiency of this embodiment reaches 92.4%, while the total efficiency of the comparative example is only 83.6%, indicating that the finished product prepared by this embodiment is better and has good market promotion value.

[0023] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
