Large-size composite bulletproof glass

The invention discloses large-size composite bulletproof glass which comprises a combined functional glass layer and a bulletproof glass layer, and a hollow layer is formed between the combined functional glass layer and the bulletproof glass layer. Wherein the bulletproof glass layer comprises a plurality of pieces of float glass, a first film is arranged between every two adjacent pieces of float glass, and an explosion-proof film is arranged on the outer surface of the float glass farthest from the hollow layer; the combined functional glass layer comprises more than two pieces of semi-tempered glass, and a second rubber sheet is arranged between every two adjacent pieces of semi-tempered glass. According to the bulletproof glass, the most economical mode is adopted, the bulletproof effect is achieved with the minimum total thickness of the glass, meanwhile, the different requirements of energy conservation for thermal performance are met through flexible combination and adjustment of ...
