Homothermal double-layer toughened glass

The invention discloses homothermal double-layer toughened glass and belongs to the field of toughened glass. The homothermal double-layer toughened glass comprises upper toughened glass, lower toughened glass, a heating wire, laminated glass cement and a thermostatic controller. The heating wire is arranged between the upper toughened glass and the lower toughened glass. The heating wire, the upper toughened glass and the lower toughened glass are fixed through the laminated glass cement. The thermostatic controller is connected with the heating wire. According to the invention, a layer of the heating wire is sandwiched between the double layers of the toughened glass, and the heating wire with a copper alloy signal line and the thermostatic controller are used to control temperature of the toughened glass to be constant at a set value. Thus, the phenomenon that toughened glass is easy to break automatically in a low-temperature environment is minimized, and safety of toughened glass windows is enhanced. The homothermal double-layer toughened glass also can be used as a material of a thermotank and used in the aspects of hatching and the like.
