Problems solved by technology

[0002] At present, in order to meet the energy-saving requirements of modern buildings, most of the building curtain walls and glass windows use LOW-E insulating glass windows to meet the functional requirements, but the heat transfer coefficient index generally can only reach about 1.78; in order to improve the thermal insulation performance, a A kind of heat-insulating glass (glass with a vacuum layer interlayer), which is characterized by a heat transfer coefficient of about 0.5, but requires high-temperature production, high cost, heavy weight, difficult manufacturing process, and difficult to promote on a large scale and mass-produce

Embodiment 1

[0026] see Figure 1a ~ Figure 1c , Figure 1a ~ Figure 1c Shown is an insulating sheet fixed to the pane, covering the entire pane but not the frame. The thermal insulation sheet includes three layers of support frames 3 made of wood soaked in fireproofing liquid. Adjacent support frames 3 are bonded to each other. A light-transmitting sheet 1 is provided, and the light-transmitting sheet 1 is glued on the support frame 3 . The insulation sheet also has good air pressure regulation. The air pressure adjustment method is to have one or two small pressure-regulating holes with a diameter of 1 to 2 mm on a certain side frame of each layer of air grid, so that the internal air of the insulation sheet can pass through. The small pressure regulating hole on the support frame is connected with the outside.

[0027] In order to further improve the fireproof performance of the insulation sheet, a fireproof layer can be coated on the surface of the insulation sheet. In order to imp...

Embodiment 2

[0031] see Figure 2a ~ Figure 2c , the difference with embodiment 1 is: support frame 3 has four layers, is made of polyurethane, and the thickness of every layer of support frame is 6mm, and light-transmitting sheet has three layers, is made of PET transparent film, and thickness is 0.2mm. mm, the overall thickness of the formed thermal insulation sheet is 27mm, the shape of the pattern layer 4 glued to the light-transmitting sheet 1 is different, and the rest of the structure is the same as that of Embodiment 1.

[0032] The test results of the above-mentioned insulation window in the laboratory are: when the heat transfer coefficient is measured as 2.7 without the insulation sheet, the heat transfer coefficient is reduced to 0.9mm after the insulation sheet is added. The combustion performance of the insulation sheet is Class C.

Embodiment 3

[0034] see Figure 3a ~ Figure 3c , the difference with embodiment 1 is that: the support frame 3 has six layers, made of extruded polystyrene board, and the outside three-layer support frame 3 covers the window frame of the glass window, and the inside three-layer support frame 3 covers the The surrounding of the window glass does not cover the window frame of the glass window, so the thermal insulation effect is better; the thickness of each support frame is 8mm; the light-transmitting sheet has 5 layers, which is made of flame-retardant PC film, and the thickness is 0.1mm; The overall thickness of the formed thermal insulation sheet is 52mm; the shape of the pattern layer 4 glued on the transparent sheet 1 is different. All the other structures are identical to Embodiment 1.

[0035] The test results of the above-mentioned insulation window in the laboratory are: when the heat transfer coefficient is measured as 2.7 without the insulation sheet, the heat transfer coefficie...

Abstract

The invention discloses a composite heat-insulating window, which comprises a glass window; a heat-insulating sheet is fixed on the glass window; the heat-insulating sheet comprises at least three layers of supporting frames made of heat-insulating materials; the adjacent supporting frames are bonded; light-transmitting sheets are arranged among the adjacent supporting frames; the light-transmitting sheets are bonded on the supporting frames; and the supporting frames are provided with pressure regulating holes connecting the interior and the exterior of the heat-insulating sheets. A structure of the composite heat-insulating sheet on the glass window is adopted by the invention, the organic combination of at least two materials is used for the heat-insulating sheet; a large area of supporting main materials have a very low heat conductivity coefficient, and parts of the materials have light-transmitting property and are combined in at least two layers, so that the heat-insulating window has good heat-insulating performance, the energy consumption of a building is reduced, and energy conservation and consumption reduction of the overall process of a building product are really realized, so the invention is suitable for construction of the new building and transformation of the old building, and the low carbon economy is better realized more efficiently. The composite heat-insulating window is produced at the normal temperature, so the energy consumption is reduced; the production technology is simple, the overall weight is lighter, and the cost is lower; and the composite heat-insulating window is suitable for rapid mass production.
