Abstract

The invention provides a glass plate stacking structure for glass forming, a forming method of the glass plate stacking structure and bulletproof glass, and the bulletproof glass comprises at least three flat glass plates which are mutually stacked, wherein the sizes of all the glass plates are sequentially increased or sequentially decreased according to the stacking direction, overlapping differences exist at the edges of adjacent glass plates, shielding layers are arranged between the adjacent glass plates, at least one shielding layer is arranged between the adjacent glass plates, at least part of the shielding layers are arranged along the edges of the glass plates and cover the overlapping differences between the adjacent glass plates, and gaskets are arranged between the shielding layers and the glass plates adjacent to the shielding layers, and the sizes of the gaskets are larger than or equal to those of the glass plates adjacent to the shielding layers. The method has the advantages of avoiding the direct contact between the shielding layer of the lower glass plate and the upper glass plate, ensuring the integrity of the shielding layer on the lower glass plate by bearing the pressure of the upper glass plate by the gasket, and realizing the formation of a final finished product under the condition of not damaging the basic structure of the bent glass by taking out the gasket after molding.
