preparation example Construction

[0019] The method for preparing bullet-proof glass of the present invention includes the following steps: (a) cutting the first semi-finished glass and the second semi-finished glass into the same size; (b) semi-tempering the first semi-finished glass after cutting, and then After preheating, immerse it in 300-500°C potassium salt molten liquid to react for 1-3 hours, and finally lift it to an annealing furnace to cool to room temperature to form the first tempered glass; (c) cut the second tempered glass The semi-finished glass is tempered, then preheated and immersed in a potassium salt melt at 400-500°C for 3-5 hours to react, and finally lifted to an annealing furnace to cool to room temperature to form the second tempered glass; (d) The first tempered glass can be pasted on both sides of the second tempered glass through polyvinyl butyral films; the step (b) and the step (c) are in no particular order. Since the first glass semi-finished product is semi-tempered and then ...

Embodiment 1

[0024] The present embodiment provides a kind of preparation method of bulletproof glass, comprises the following steps:

[0025] (a) cutting the first glass semi-finished product and the second glass semi-finished product to the same size;

Abstract

The invention relates to a preparation method of bullet-proof glass and bullet-proof glass prepared by the method. The preparation method of bullet-proof glass comprises the following steps: (a) cutting; (b) carrying out semi-tempering treatment on a first glass semi-finished product formed after cutting, then preheating the first glass semi-finished product, then dipping the first glass semi-finished product in a potassium salt molten solution at the temperature of 300-500 DEG C for reacting for 1-3 hours, finally lifting the first glass semi-finished product in a cooling furnace and cooling to the room temperature; (c) tempering a second glass semi-finished product after cutting, then dipping the second glass semi-finished product in a potassium salt molten solution at the temperature of 400-500 DEG C for reacting for 3-5 hours, finally lifting the second glass semi-finished product in the cooling furnace and cooling to the room temperature; and (d) respectively correspondingly attaching the first tempered glass on two surfaces of the second tempered glass by virtue of a polyvinyl butyral film. On the one hand, the glass semi-finished product is semi-tempered and then chemically tempered, and the strength of the bullet-proof glass can be effectively improved by combination of physical tempering and chemical tempering; on the other hand, two types of tempered glass can be sandwiched by glue and attached by using the film, and the thickness and the weight of the glass can be reduced.

Description

technical field [0001] The invention belongs to the field of glass processing and relates to a glass, in particular to a bulletproof glass and a preparation method thereof. Background technique [0002] Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. It is usually a transparent material, such as PVB (polyvinyl butyral) / polycarbonate fiber thermoplastic. It has the appearance of ordinary glass and the behavior of transmitting light, providing some protection against small arms fire. [0003] 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 l...
