Detailed ways

The present invention will be described in detail below with reference to the drawings and specific embodiments. Note that the following aspects described in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention in any way.

As shown in FIG. 1, the embodiment of the present invention discloses a vacuum organic plate composite insulating glass, which includes a vacuum part 102 placed on the inside and a glass plate 101 placed on the outside. A space is left between the vacuum part 102 and the glass plate 101. The cavity 110, the vacuum part 102 and the glass plate 101 are surrounded by a sealing member 107 ("around" in this text refers to the peripheral edge position), the vacuum part 102 includes at least two organic transparent plates 105, the number of organic transparent plates 105 It can be determined according to needs. In this embodiment, the vacuum unit 102 includes two organic transparent plates 105. An airtight cavity 104 is formed between the organic transparent plates 105, and the inside of the airtight cavity 104 is evacuated.

It should be noted that the "organic transparent board" in the present invention does not specifically refer to a certain material, but refers to a general term for organic material boards that have a certain strength and can withstand vacuum pressure and have a certain degree of light transmittance. For example, it may include But it is not limited to polycarbonate board, polymethyl methacrylate board (ie acrylic board), polystyrene board, polyvinyl chloride board, PETG board or resin board. The thickness of the organic transparent plate 105 may be 0.2 mm to 0.4 mm. In this embodiment, a 0.3 mm thick polycarbonate plate is used.

The main innovation of the present invention is to creatively use the organic transparent plate 105 instead of glass to form the vacuum part, and cooperate with the outer glass plate 1 to form composite glass. Compared with the vacuum hollow composite glass with the same thermal insulation performance, the overall thickness is greatly reduced.了weight. For example, the vacuum glass combination with the same heat transfer coefficient is 5mm glass+12mm air+5mm glass+2mm vacuum+5mm glass+12mm air+5mm glass=46mm, while the thickness of the present invention is 5mm glass+12mm air+0.3mm organic transparent Board + 2mm vacuum + 0.3mm organic transparent board + 12mm air + 5mm glass = 36.6mm, which reduces the thickness by nearly 10mm while maintaining the thermal insulation performance, while reducing the weight by nearly 1/2.

In addition, the thermal insulation performance of the present invention is also greatly improved compared with the prior art. The heat transfer coefficient of insulating glass is generally about 3.0W/(m ² ·K), and the heat transfer coefficient of traditional composite glass is generally 1.9W/(m ² ·K), and the heat transfer coefficient of the embodiment of the present invention can reach 0.7W/(m ² ·K), and the heat preservation and heat insulation performance is excellent.

Preferably, the same material can be used to seal around the organic transparent plate 105 to form a closed cavity (vacuum) 104, so as to ensure that the closed cavity (vacuum) 104 is not easy to enter air and ensure its heat preservation performance. For the vacuuming process of the closed cavity (vacuum) 104, the existing technology can be used, and the present invention is not limited. For example, an opening can be opened on the organic transparent plate 105, and the inside can be vacuumed and sealed with a rubber ball or the like.

In order to prevent the organic transparent plate 105 from being excessively deformed under the action of air pressure, a first support 103 may be provided between the organic transparent plate 105. Preferably, the first support 103 uses the same material as the organic transparent plate 105 to maintain the same thermal expansion performance.

In a possible embodiment, the organic transparent plate 2 is provided with edge ribs 106 extending outwardly, and the edge ribs 106 are supported between the organic transparent plate 105 and the glass plate 101, and can play a supporting role as well as a sealing member. 107 bracket. Similarly, the side ribs 106 are preferably made of the same material as the organic transparent plate 105.

In a possible embodiment, the vacuum part 102 is centrally arranged between the glass plates 101. Those skilled in the art can easily understand that the vacuum part 102 can also be offset to both sides, but it cannot be attached to the glass plates 1 on both sides. The cavity 110 between the vacuum part 102 and the glass plate 1 can be filled with different gases as required.

In a possible embodiment, the sealing element 107 includes a sealing strip 108 arranged around the organic transparent plate 105 and a sealant 109 filled between the sealing strip 108 and the glass plate 101, and the sealing strip 108 can be arranged on the outside of the side rib 106 , Through the cooperation of the sealing strip 108 and the sealant 109, the cavity 110 can be sealed to prevent water vapor from entering the interior.

FIG. 2 is a schematic cross-sectional view of another embodiment of the present invention, which shows a structure with three organic transparent plates 201. Correspondingly, a first support 202 is arranged between the organic transparent plates 201. In addition, in order to maintain the distance between the organic transparent plate 201 and the glass plates 204 on both sides, a second support 203 may be provided between the organic transparent plate 201 and the glass plate 204.

In summary, compared with the composite glass in the prior art, the present invention uses an organic transparent plate to replace the traditional vacuum glass plate, which reduces the overall thickness while reducing the weight, and can achieve better heat preservation and heat insulation. Sound insulation performance.
