Description

Technical Field

[0001] The utility model relates to the technical field of hollow glass, in particular to a warm edge strip of hollow glass. Background Art

[0002] Hollow glass currently uses aluminum alloy strips and coated plastic strips for single-pass sealing and double-pass sealing gluing. Traditionally, edge strips made of aluminum alloy are used, but considering the high thermal conductivity of aluminum alloy, the energy loss of forming hollow glass is very large. According to laboratory data, the thermal conductivity of aluminum spacers is 0.106W / MK, and the thermal conductivity of warm edge strips is 0.047W / MK.

[0003] The current warm edge strips are designed to replace the original aluminum alloy edge sealing to ensure the thermal insulation effect of insulating glass. However, the existing warm edge strips have a simple structure and mostly adopt PET material lamination and gluing process, which has poor anti-aging and durability effects. After long-term use, aging will occur, the sealing effect is poor, air leakage, water ingress, and film debonding. It is easy for the entire spacer to fall off from the inner cavity of the insulating glass, causing unnecessary dangers and safety hazards. Utility Model Content

Example

It is easy for the entire spacer to fall off from the inner cavity of the hollow glass, resulting in unnecessary dangers and safety hazards. The overall idea is as follows:

[0017] In view of the problems existing in the prior art, the utility model provides a warm edge strip for insulating glass, including an ASA fiber-reinforced body 11. The warm edge strip in the device adopts ASA, a ternary graft copolymer with the same characteristics as the insulating glass, which is super weather-resistant, UV-resistant, high and low temperature resistant, anti-static, and reduces dust accumulation. The ternary graft copolymer ASA is a polymer material formed by graft copolymerization of acrylonitrile, styrene and acrylate. This material combines the characteristics of the three monomers, exhibits a unique performance combination, has extremely high resistance to ultraviolet rays, is not easy to fade and age under long-term exposure to outdoor conditions, has high impact strength and good dimensional stability, can be injection molded, extruded and other molding processes within a wide processing temperature range (about 170°C to 230°C), and has a smooth surface and stable color, and is suitable for making appearance parts.

[0018] The ASA fiber reinforced body 11 is provided with a high airtight outer layer 12, a high airtight layer 13 is formed between the ASA fiber reinforced body 11 and the high airtight outer layer 12, and a high-efficiency unobstructed air hole channel 14 is opened on the air permeable surface of the ASA fiber reinforced body 11. The ASA fiber reinforced body 11 is made of ASA plus glass fiber material, and the thickness of the ASA fiber reinforced body 11 is 1mm. The high airtight outer layer 12 is made of ASA material, and the thickness of the high airtight outer layer 12 is 0.2-0.3mm. The air holes are improved by the edge strips, and the original small round holes are not smooth. They are designed as rectangular high-efficiency unobstructed air hole channels 14, which are convenient for the desiccant to fully contact the gas in the cavity. The width of the partition strip is less than 12mm for single row and greater than 12mm for double row. The partition strip is made of composite material. At the same time, the high airtight outer layer 12 and the high airtight layer 13 in the equipment are used on the outside, while the high-efficiency unobstructed air hole channel 14 is used on the inside, which is a visible surface, and the rest are non-visible surfaces.

[0019] The back of the ASA fiber reinforced body 11 is provided with an anti-leakage air layer, which is made of ASA material and is compounded on the back of the ASA fiber reinforced body 11 through a co-extrusion process. The shape of the efficient and unobstructed pore channel 14 is rectangular, the width of the efficient and unobstructed pore channel 14 is 0.4 mm, and the length of the efficient and unobstructed pore channel 14 is 2 mm.

[0020] The utility model has a reasonable design and good heat insulation performance, and can effectively and fully absorb the water vapor in the inner cavity to the maximum extent, avoiding the safety hazard of the partition strip falling off in the inner cavity, avoiding the phenomenon of thermal expansion and contraction, ensuring the sealing effect, and at the same time reducing the heat transfer of the glass, improving the heat insulation performance, significantly improving the sealing performance, and significantly improving the anti-aging effect and weather resistance, and the actual use effect is good.

[0021] Working principle: The warm edge strips in the device are made of the same ASA graft copolymer as the insulating glass, which is super weather-resistant, UV-resistant, high and low temperature resistant, anti-static, and reduces dust accumulation. The graft copolymer ASA is a polymer material formed by graft copolymerization of acrylonitrile, styrene and acrylate. This material combines the characteristics of the three monomers and exhibits a unique performance combination. It has extremely high resistance to ultraviolet rays, is not easy to fade and age under long-term exposure to outdoor conditions, has high impact strength and good dimensional stability, and can be used in a wide range of processing temperatures. The air holes of the side strips are improved. The original small round holes are not smooth. They are designed as rectangular high-efficiency and smooth air hole channels 14, which are convenient for the desiccant to fully contact the gas in the cavity. The width of the spacer strips is less than 12 mm for single row and greater than 12 mm for double row. The spacer strips are made of composite materials. At the same time, the high airtight outer layer 12 and the high airtight layer 13 in the equipment are used on the outside, while the high-efficiency and smooth air hole channels 14 are used on the inside, which are visible surfaces, and the rest are non-visible surfaces.

[0022] The utility model has a reasonable design and good heat insulation performance, and can effectively and fully absorb the water vapor in the inner cavity to the maximum extent, avoiding the safety hazard of the partition strip falling off in the inner cavity, avoiding the phenomenon of thermal expansion and contraction, ensuring the sealing effect, and at the same time reducing the heat transfer of the glass, improving the heat insulation performance, significantly improving the sealing performance, and significantly improving the anti-aging effect and weather resistance, and the actual use effect is good.
