Dry air or inert gas such as argon is filled in the spacing layer, and the spacing frame material mainly includes aluminum strip and stainless steel strip, which serves to support and fix the glass sheet and ensure the uniform thickness of the spacing layer.

DETAILED DESCRIPTION

[0020] The utility model will be made further detailed explanation in combination with the drawings and specific implementation.

[0021] As Figs. 1-3 shown, a long-life hollow glass with waterproof and moisture absorption performance comprises at least two glass plates 1 arranged in stack, the adjacent glass plates 1 are kept isolated to improve the overall heat preservation and protection effect, and the glass plates 1 are fixed with sealing frames 2 along the circumference to fix the whole. In order to further improve the internal sealing effect, the sealing frames 2 are filled with sealing glue 3 between the glass plates 1, which simultaneously improves the connection stability of the glass plates 1 and the sealing frames 2. The sealing frame 2 has a dehumidification assembly 4 extending to the glass plates 1, and a negative pressure assembly 5 is arranged between the dehumidification assembly 4 and the sealing frame 2. Unlike the existing drying and dehumidification method, the dehumidification assembly 4 in the embodiment absorbs the excess moisture of the glass plates 1, and the negative pressure assembly 5 maintains a micro-negative pressure environment inside to ensure that the gap is completely sealed.

[0022] Specifically, the sealing frame 2 is made of aluminum alloy material, which has a long service life and structural strength, wherein the sealing glue 3 is made of butyl rubber material to adapt to outdoor environment, and the glass plates 1 have a gap of 3-6mm between them to ensure the basic heat preservation effect.

The sealing glue 3 simultaneously protects the surface of the glass plates 1 and has good buffering effect.

[0024] Further, the dehumidification assembly 4 is designed in a hidden manner and specifically comprises a dehumidification groove 41 arranged on the sealing frame 2, the dehumidification groove 41 is filled with a strip-shaped desiccant 42, the desiccant 42 usually adopts a silica gel strip, and cobalt chloride is added to the silica gel strip to indicate the water absorption state. The dehumidification groove 41 is provided with a moisture absorption hole 43 at the bottom, which is communicated with the gap between the adjacent glass plates 1, and the port of the dehumidification groove 41 is closed by a dehumidification cover plate 44. After the desiccant 42 is tightly fixed, the inside of the glass plates 1 is maintained in a dry environment.

[0025] Further, in order to determine whether the sealing state is good in time, the negative pressure assembly 5 comprises a negative pressure sheet 51 covering the dehumidification groove 41 and the dehumidification cover plate 44, the middle part of the negative pressure sheet 51 is provided with a one-way valve nozzle 52, and the middle part of the negative pressure sheet 51 is provided with an arch-shaped part 53 protruding from the surface thereof. When the glass plate 1 is depressurized, the arch-shaped part 53 of the negative pressure sheet 51 is ejected, at which time the negative pressure sheet 51 affects the sliding of the sealing frame body 2 as a whole.

[0026] In addition, the sealing frame body 2 is internally provided with a first structural cavity 24 and a second structural cavity 25 extending in the circumferential direction, and the first structural cavity 24 and the second structural cavity 25 are internally arranged with reinforcing ribs 26.

[0027] Meanwhile, the outer side of the glass plate 1 is attached with a waterproof layer 6 made of polyvinyl butyral, and the waterproof layer 6 extends to the joint between the glass plate 1 and the sealing frame body 2. The waterproof layer 6 completely seals the gap between the glass plate 1 and the sealing frame body 2, and maintains the structural stability when the glass plate 1 is broken, avoiding the falling of glass fragments.

[0028] Obviously, the outer surface of the sealing frame body 2 is further coated to prolong the service life thereof.

[0029] Obviously, the upper and lower ends of the sealing frame body 2 are provided with sliding grooves 7, and the sliding grooves 7 are fixedly installed with lubricating strips 71 made of polytetrafluoroethylene. The sliding grooves 7 are opposite to the negative pressure assembly 5, and the glass plate 1 is subjected to pressure extraction through the sliding grooves 7.

[0030] Preferably, the middle part of the sealing frame body 2 is provided with a support strip 72 pressed against the outer surface of the glass plate 1, and this structure is mainly suitable for large-area glass plates 1, and different shapes of support strips 72 can be selected for external reinforcement according to actual needs.
