Embodiment 1

[0040] 1. Flat glass substrate processing:

[0041] The original glass sheet is selected, cleaned and dried, and its surface strength is improved by physical toughening to obtain a semi-tempered glass substrate, and its surface stress is controlled at 24-69Mpa. Next, remove grease and dust on the surface of the semi-tempered glass substrate, and air-dry it.

[0042] 2. The first assembling, pre-pressing and autoclaving:

[0043] Ensure that the laminating room is hygienic and the PVB film is clean, and then follow the lamination sequence of semi-tempered glass substrate, PVB film, and semi-tempered glass substrate in an environment with a temperature of 20±3°C and a relative humidity of 23%±5%. Lamination is carried out to obtain a glass combination. During the stacking process, the four sides should be aligned and there should be no stack difference. There must be no pollutants between the glass and the PVB film.

[0044] Put the stacked glass combination on the roller pr...

Embodiment 2

[0052] The preparation process of embodiment 2 is the same as that of embodiment 1, the difference is that the glass structure of embodiment 2 is: glass substrate / PVB film / glass substrate / PVB film / glass substrate / PU film / PC board, total thickness is 28.55mm mm.

Embodiment 3

[0054] The preparation process of embodiment 2 is the same as that of embodiment 1, the difference is that the glass structure of embodiment 2 is: glass substrate / PVB film / glass substrate / PVB film / glass substrate / PU film / PC board, total thickness is 33.19 mm.

Abstract

The invention discloses a preparation method of impact-resistant high-strength bulletproof glass. The preparation method comprises the following steps: S1, cleaning and air-drying a semi-tempered glass substrate; S2, performing lamination according to the superposing sequence of the semi-tempered glass substrate and the PVB film; S3, placing the superposed glass combination on a roller press for pre-pressing; S4, feeding the pre-pressed glass combination into an autoclave for autoclaving to obtain a semi-finished product glass substrate interlayer combination; S5, overlapping according to an overlapping sequence of the semi-finished product glass substrate interlayer combination, the PU film and the PC board to obtain a combined material; S6, the laminated combined material is put into a vacuum bag to be subjected to edge sealing treatment; and S7, autoclaving the combined material for 4-6 h under the conditions that the temperature is 110-120 DEG C and the pressure is 1.1-1.25 Mpa, thus producing the bullet-proof glass. The invention also discloses the bullet-proof glass prepared by the method. According to the bulletproof glass prepared by the invention, the overall dead weight can be reduced by about 20%-30%, and meanwhile, the impact resistance and bulletproof performance are kept unchanged.

Description

technical field [0001] The invention relates to the technical field of bulletproof glass, in particular to an impact-resistant high-strength bulletproof glass and a preparation method thereof. Background technique [0002] In recent years, terrorist attacks on a global scale have occurred from time to time, and the damage caused by bomb explosions is relatively large, which not only poses a serious threat to the lives of people outdoors, but also causes great harm and harm to people indoors nearby. loss. According to the analysis of security experts and related data, 75% of the injuries caused by bomb explosions are directly related to the scattering of building glass and the splashing of fragments. the main reason. [0003] At present, the existing bullet-proof glass preparation process usually adopts two pre-pressing and autoclaving processes, wherein the second pre-pressing and autoclaving are carried out step by step, and the pre-pressing adopts the roller pressing met...
