Problems solved by technology

And the traditional bullet-proof glass can be bullet-proof, but the anti-smashing effect is much worse. In the important part of the bank, the glass is required to be bullet-proof and smash-proof at the same time. Therefore, a glass that is both bullet-proof and smash-proof is needed.

Embodiment Construction

[0022] Selected raw material configuration: 8mm white glass + 1.14mm PVB film + 8mm white glass + 1.14mm PVB film + 8mm white glass + 1.14mm PVB film + 5mm white glass, the white glass adopts high-quality float method with low iron content and good flexibility Glass is used as the original film. PVB film (polyvinyl butyral) is made of imported high-quality PVB anti-tear film (DuPont or Solutia). The production steps are:

[0023] 1) Cut glass and PVB film;

[0024] 2) Clean and dry the glass;

[0025] 3) Combine glass and PVB film;

[0026] 4) Carry out the initial pressure, the initial pressure temperature is adjusted to 215°C, and the initial pressure is 0.6MPa;

[0027] 5) Carry out high temperature and high pressure in the autoclave, the inflation temperature remains unchanged at 40°C, the equilibrium temperature is 140°C, the equilibrium pressure is 1.25MPa, the equilibrium time is 60 minutes, the exhaust temperature is 40°C, and the cooling time of the glass in the aut...

Abstract

The invention relates to a bulletproof and smash-proof composite glass. High-quality float glass with low iron content and high flexibility is used as an original film; an imported high-quality polyvinyl butyral (PVB) anti-tearing rubber sheet (Dupont and Solutia) is used as a middle layer; by a series of processing technologies of cleaning, preliminary pressing, high-temperature and high-pressure operation, aging treatment and the like, external bullets can be resisted, and impact of external violence such as stones and hammers can be effectively resisted.

Description

technical field [0001] The invention relates to a composite glass, in particular to a bulletproof glass and a manufacturing method thereof. Background technique [0002] Bulletproof glass is used in financial system business places such as banks, credit unions, and postal savings, as well as valuables storage places such as museums and exhibition halls, to provide security for relevant staff, cash, securities, and important vouchers. [0003] The production and processing of traditional bulletproof composite glass adopts wet processing. Wet processing is to directly pour glue in the middle of the glass and then irradiate it with ultraviolet rays. The finished glass has low light transmittance, and there are easy bubbles and overlapping shadows around it. The service life is about three years. And the traditional bullet-proof glass can be bullet-proof, but the anti-smashing effect is much worse. In the important part of the bank, the glass is required to be bullet-proof and ...
