Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building materials, and particularly relates to a light-weight safe energy-saving composite hollow glass and a manufacturing method thereof. BACKGROUND

[0002] Hollow glass has been used in the field of construction for more than a hundred years, and has the characteristics of good transparency, sound insulation and heat preservation. The specific gravity of glass is 2500 kg / m³. In order to save energy and heat preservation, three single-layer glasses are usually used to form a hollow glass. Taking a glass thickness of 6 mm as an example, the weight of 1 square meter of three-layer hollow glass is 45 kg (the weight of the spacer and the sealant is not included). The weight of the glass itself has a high requirement on the frame material and hardware of the door and window, and increases the weight of the door and window and the load of the building, which is not conducive to the reasonable saving and carbon reduction of building materials.

[0003] Glass is a fragile product. Even if it is tempered glass or laminated glass, its safety cannot be guaranteed. Under the action of external force, tempered glass and laminated glass can be easily penetrated, which is not conducive to safety, theft prevention and anti-impact.

[0004] The current mainstream application of energy-saving glass on the market is LOW-E tempered hollow glass. The spacer layer of the hollow glass plays a role in blocking convection and reducing heat conduction. LOW-E is realized by magnetron sputtering silver on the inner surface of the outer glass to reflect infrared rays, so it has the characteristics of heat insulation and heat preservation. However, the LOW-E tempered hollow glass only blocks the heat of radiation, and the glass itself has a large thermal conductivity coefficient. The coating does not change the heat conduction performance of the glass, which is also a defect of the hollow glass in energy saving.
