Embodiment 1

[0108] The airgel composite glass was prepared by the following steps:

[0109] (1) Mix ethyl orthosilicate, ethanol, deionized water, and hydrochloric acid in a molar ratio of 1:8:2:1×10 -3 Mix and stir evenly, after fully hydrolyzed, then according to the molar ratio of ethyl orthosilicate and ammonia water 1:2.5×10 -3 Add ammonia water, mix and stir to obtain sol;

[0110] (2) Cast the prepared sol into the through hole of the honeycomb core 41 pre-placed in the mold, wherein the shape of the through hole is a cylinder, the diameter of the hole is 10mm, the height is 9mm, and the thickness of the hole wall is 0.1mm. , after being gelled, the mold is demoulded, and the honeycomb core 41 containing the gel is directly put into a drying kettle for carbon dioxide supercritical drying to obtain a composite honeycomb core 4;

[0111] (3) Place the composite honeycomb core 4 between two pieces of float glass (1, 2), use butyl sealant 5 and bridge-breaking aluminum spacer frame ...

Embodiment 2

[0114] (1) Mix ethyl orthosilicate, ethanol, deionized water, and hydrochloric acid in a molar ratio of 1:10:6:1.8×10 -3 Mix and stir evenly, after fully hydrolyzed, then according to the molar ratio of ethyl orthosilicate and ammonia water 1:3.6×10 -3 Add ammonia water, mix and stir to obtain sol;

[0115] (2) Cast the prepared sol into the through hole of the honeycomb core 41 pre-placed in the mold, wherein the shape of the through hole is a regular hexagonal prism with a diameter of 20 mm, a height of 12 mm, and a wall thickness of 0.5 mm. After being gelled, the mold is demoulded, and the honeycomb core 41 containing the gel is directly put into a drying kettle for carbon dioxide supercritical drying to obtain a composite honeycomb core 4;

[0116] (3) Place the composite honeycomb core 4 between two pieces of float glass (1, 2), use butyl sealant 5 and bridge-breaking aluminum spacer frame 3 to bond and seal around the composite honeycomb core 4, and reuse The silicon...

Embodiment 3

[0119] (1) Mix ethyl orthosilicate, ethanol, deionized water, and hydrochloric acid in a molar ratio of 1:3:2:0.8×10 -3 Mix and stir evenly, after fully hydrolyzed, then according to the molar ratio of ethyl orthosilicate and ammonia water 1:1.6×10 -3 Add ammonia water, mix and stir to obtain sol;

[0120] (2) Cast the prepared sol into the through hole of the honeycomb core 41 pre-placed in the mold, wherein the shape of the through hole is a regular square prism, the aperture is 80 mm, the height is 40 mm, and the thickness of the hole wall is 1 mm. , after being gelled, the mold is demoulded, and the honeycomb core 41 containing the gel is directly put into a drying kettle for carbon dioxide supercritical drying to obtain a composite honeycomb core 4;

[0121] (3) Place the composite honeycomb core 4 between two transparent polycarbonate plates (1, 2), and use epoxy resin sealant 5 and fiber-reinforced plastic spacer frame 3 to bond and seal around the composite honeycomb...

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, the 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 honeycomb core, the composite honeycomb core comprises a honeycomb core body and aerogel, the honeycomb core body is formed by arranging a plurality of through holes with the same height in parallel, the through holes are perpendicular to the first light-transmitting plate and the second light-transmitting plate in the height direction, and the through holes are filled with the aerogel. The manufacturingmethod comprises the steps that the honeycomb core containing the gel is directly placed into a drying kettle to be dried and then placed between the two light-transmitting plates to be assembled, andthe honeycomb core containing the gel is obtained. The aerogel composite glass disclosed by the invention not only has excellent properties 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...
