Abstract

The invention relates to the technical field of glass, in particular to bullet-proof glass. The bullet-proof glass comprises inner layer glass, one to three layers of middle layer glass and outer layer glass, wherein a polycarbonate plate is arranged between every two layers of glass partially or totally; each layer of glass and the polycarbonate plate are bonded by a PVB (polyvinyl butyral) glue sheet layer or a polyurethane glue layer; the thickness of the inner layer glass is 5 to 7mm; the thickness of the middle layer glass is 3 to 5mm; the thickness of the outer layer glass is 4 to 6mm; the thickness of the polycarbonate plate is 2 to 5mm; the thickness of the PVB glue sheet layer or polyurethane glue layer is 0.5 to 2mm. The preparation is easy; the bullet-proof capability is high; after each layer of glass uses wired glass, high anti-impact capability can be realized, so that the bullet-proof capability of the glass is higher.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to bulletproof glass. Background technique [0002] Safety glass is usually used in some important facilities, such as bank gates, valuables display cabinets, doors and windows of prisons and correctional institutions, etc. These parts may be successively attacked by bandits armed with various weapons. The high-strength safety glass can resist penetration for a period of time, buying enough time for other devices to react. As a special safety glass, bullet-proof glass can resist bullets within a certain distance without being penetrated while meeting the observation requirements, and protect personal safety to the greatest extent. heat, cold and other characteristics. Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. At present, bulletproof glass is basically obtained by sandwiching an organic m...
