Description

Hollow glass with good sound and heat insulation effects Technical Field The utility model relates to the technical field of glass, in particular to hollow glass with good sound and heat insulation effects. Background The hollow glass is generally composed of two or more layers of flat glass, the periphery of the hollow glass is made of high-strength and high-air-tightness composite adhesive, the glass sheets are bonded and sealed with sealing strips and frames (such as aluminum alloy frames or glass strips) and are manufactured through cementing, welding or fusion welding and other processes, and the manufactured glass and frames are installed on windows or windowsills. However, the sound insulation performance of the existing toughened hollow glass is usually obviously weaker than the heat insulation performance of the toughened hollow glass, meanwhile, the dry air filled in the hollow layer can expand or contract in volume due to temperature or air pressure change, so that the air pressure in the hollow layer is unbalanced, deformation and even structural damage of the glass panel can be possibly caused, and the sound insulation and heat insulation effects of the glass panel are reduced. Disclosure of utility model The utility model aims to solve the problems that the internal pressure of a hollow layer is easy to be fluctuated and the glass surface is easy to deform or even break in the prior art, and provides hollow glass with good sound and heat insulation effects. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The hollow glass with good sound and heat insulation effects comprises a frame, a limiting structure, at least three groups of glass, a third group of glass and a fourth group of functional coating, wherein the limiting structure is formed on the inner side surface of the frame, sealing elements are filled in the limiting structure, a first hollow cavity and a second hollow cavity are formed between two adjacent groups of glass, inert gas and vacuum are respectively arranged in the first hollow cavity and the second hollow cavity, a first functional coating is arranged on the glass surfaces forming the first hollow cavity and the second hollow cavity, the second functional coating is arranged on the outer side surface of one group of glass, and the third functional coating is arranged on the outer side surface of the other glass.
