Abstract

The invention discloses fireproof and anti-electromagnetic radiation glass and a preparation method thereof. The glass sequentially comprises a bottom glass layer, an inner glass layer, an inside glass layer and a surface glass layer which are separated through separation layers, wherein the separation layers at least include a vacuum layer, a waterproof glue layer and an anti-electromagnetic radiation shielding layer, and each separation layer is one of the vacuum layer, the waterproof glue layer and the anti-electromagnetic radiation shielding layer. A layer of anti-electromagnetic radiationshielding glass is arranged in the fireproof and anti-electromagnetic radiation glass, and meanwhile, at least one piece of glass is coated with a Low-E film, so that the heat conduction and the heatradiation are both interdicted, the high-temperature injury in a fire disaster is effectively prevented, and the glass has the functions of preventing electromagnetic radiation and information leakage and protecting information safety. By utilizing nano-silicon dioxide water glass as fireproof glue, the fireproof and anti-electromagnetic radiation glass has good ageing resistance and fireproof performance.

Description

technical field [0001] The invention relates to the technical field of special glass, in particular to a fire-proof and electromagnetic-radiation-proof glass with long fire-proof time, good heat-insulation effect and electromagnetic-radiation protection and a preparation method thereof. Background technique [0002] With the rapid development of national construction, there are more and more high-rise buildings in cities, and public facilities such as high-speed rail and subway are becoming more and more popular. In order to protect the safety of the people and public property, people's health, fire safety, electromagnetic radiation safety, and national Safety has become more and more important. Fire-resistant glass is widely used because it can not only meet the requirements of lighting, but also have the delay effect of smoke insulation, heat insulation and flame prevention in the event of a fire. The fire-resistant properties of fire-resistant glass can provide valuable ...
