Embodiment 1

[0081] The airgel composite glass was prepared by the following steps:

[0082] (1) Arrange several airgels 42 vertically between two pieces of float glass (1, 2), wherein the airgels 42 are cylindrical in shape, with a pore diameter of 10 mm, a height of 9 mm, and a wall thickness of 0.1 mm, use butyl sealant 5 and bridge-breaking aluminum spacer frame 3 to bond around two pieces of float glass (1, 2), reserve at least one injection port, and then inject molten polycarbonate through the injection port cooling and forming in the gap between the airgel 42 to obtain a composite honeycomb core 4 placed between two pieces of float glass (1, 2);

[0083] (2) Use a spacer to seal the injection molding port, and then use silicone sealant 5 to seal the U-shaped gap formed between the bridge-breaking aluminum spacer frame 3 and the two pieces of float glass (1, 2).

[0084] The airgel composite glass obtained through the above steps has a heat transfer coefficient of 1.24W / m 2 K, the...

Embodiment 2

[0086] (1) Arrange several aerogels 42 vertically between two pieces of float glass (1, 2), wherein the shape of the aerogels 42 is a regular hexagonal prism, the aperture is 20mm, the height is 12mm, and the thickness of the hole wall is 0.5mm, use butyl sealant 5 and bridge-breaking aluminum spacer frame 3 to bond around two pieces of float glass (1, 2), reserve at least one injection port, and then inject molten polypropylene through the injection port cooling and forming in the gap between the airgel 42 to obtain a composite honeycomb core 4 placed between two pieces of float glass (1, 2);

[0087] (2) Use a spacer to seal the injection molding port, and then use silicone sealant 5 to seal the U-shaped gap formed between the bridge-breaking aluminum spacer frame 3 and the two pieces of float glass (1, 2).

[0088] The airgel composite glass obtained through the above steps has a heat transfer coefficient of 0.98W / m 2 K, the visible light transmittance is 70%, and the sola...

Embodiment 3

[0090] (1) Arrange several aerogels 42 vertically between two transparent polycarbonate plates (1, 2), wherein the shape of the aerogels 42 is a square prism with a pore diameter of 80 mm and a height of 40 mm. The thickness is 1mm, using epoxy resin sealant 5 and fiber-reinforced plastic spacer frame 3 to bond around two transparent polycarbonate plates (1, 2), reserve at least one injection port, and then pour the molten poly Methyl acrylate is injected into the gap between the airgel 42 through the injection port, cooled and molded to obtain a composite honeycomb core 4 placed between two transparent polycarbonate plates (1, 2);

[0091] (2) Use a spacer to seal the injection port, and then use silicone sealant 5 to seal the U-shaped gap formed between the fiber-reinforced plastic spacer frame 3 and the two transparent polycarbonate plates (1, 2) .

[0092] The airgel composite glass obtained through the above steps has a heat transfer coefficient of 0.31W / m 2 K, the visi...

Abstract

The invention provides aerogel composite glass and a manufacturing method thereof. The aerogel composite glass comprises a first light-transmitting plate and a second light-transmitting plate; a spacing frame is bonded between the first light-transmitting plate and the second light-transmitting plate through a sealant to form a sealed cavity; the sealed cavity is filled with a composite honeycombcore; the composite honeycomb core comprises a honeycomb core and aerogel; the honeycomb core is composed of a core body and a plurality of through holes which are arranged in parallel on the core body; and the aerogel is filled in the through holes. The manufacturing method comprises the following steps: vertically arranging the plurality of aerogels between the two light-transmitting plates, injecting the molten plastic into a gap between the aerogels, conducting cooling and molding, and finally conducting sealing. The aerogel composite glass disclosed by the invention not only has excellentproperties of heat insulation, sound insulation, fire prevention, explosion prevention and the like, but also organically combines the effects of lighting, visualization, sun shading and the like, and is suitable for the fields of doors and windows, curtain wall glass, indoor intervals, lighting roofs and the like of green buildings and ultralow-energy-consumption buildings.

Description

technical field [0001] The invention relates to the fields of lighting, visibility, heat insulation, heat preservation and sound insulation materials, in particular to an airgel composite glass and a manufacturing method thereof. Background technique [0002] As the world's largest energy-consuming country, my country's energy shortage seriously hinders the sustainable development of my country's social economy. Among them, the energy consumption of building operation is astonishing, accounting for about 30% of the total energy consumption of the whole country, and about 50% of the energy consumption of building envelopes is generated by glass windows. In order to reduce building energy consumption, the design and application of energy-saving glass windows extremely important and urgent. Airgel is a nanoporous solid material with low density, extremely low thermal conductivity, high visible light transmittance and other excellent characteristics, showing excellent light wei...
