Description

Technical Field

[0001] This utility model relates to the field of tempered glass, and in particular to a fireproof double-layer tempered glass. Background Technology

[0002] Tempered glass is a type of safety glass. It is actually a prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the load-bearing capacity and enhancing the glass's resistance to wind pressure, temperature changes, and impact.

[0003] While ordinary tempered glass has 3-5 times the impact resistance of regular glass, it can shatter instantly at high temperatures due to stress imbalance, easily causing secondary injuries in a fire. Single-pane fireproof glass, although it can withstand 800°C for 1 hour, suffers from excessive weight. Ordinary insulated glass: if some glass only focuses on sound and heat insulation, air convection in the cavity will accelerate heat transfer during a fire. Even if other glass adds an expanded graphite layer between the two panes, it has shortcomings, and the outer pane is prone to local breakage due to high temperatures, easily leading to glass breakage.
