Abstract

The invention relates to a method for manufacturing light bullet-proof glass. The method is characterized by comprising the following steps of: processing raw material glass sheets and organic glass plates into products with required specifications, cleaning and drying; sequentially laminating a panel glass sheet, a polyurethane film, an organic glass plate, a polyurethane film and a back plate glass sheet so as to obtain a combination material; putting the combination material on a flat press for pre-pressing; and feeding the pre-pressed combination material into a still kettle for steaming so as to obtain the light bullet-proof glass. The polyurethane film with high toughness and high penetration resistance and the organic glass plate replace a middle glass layer of the conventional bullet-proof glass, so that the impact resistance and penetration resistance of the glass are enhanced, the weight and thickness of the bullet-proof glass are reduced effectively, cost is lowered and the overall dead weight can be reduced by about 20 percent; simultaneously, the rigidity and intensity of the inner and outer sides of the bullet-proof glass are kept the same as those of the conventional bullet-proof glass.

Description

technical field [0001] The invention relates to a method for manufacturing glass, in particular to a method for manufacturing lightweight bulletproof glass. Background technique [0002] With the rapid development of my country's national economy, more and more places and objects need to be protected. Bulletproof glass has been rapidly promoted and used in these key protection fields due to its unique advantages. However, due to its large thickness and self-heaviness, traditional bulletproof glass not only increases the thickness of the window to a certain extent, but also wastes a lot of resources and energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light-weight bullet-proof glass manufacturing method with simple and reasonable process and light weight in view of the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the following tec...
