Abstract

The invention relates to the technical field of bulletproof, and discloses a bulletproof glass safety film which comprises at least two layers of ultra-high molecular weight polyethylene calendered films, and a bonding layer of a pressure-sensitive adhesive is arranged between the ultra-high molecular weight polyethylene calendered films. Each ultra-high molecular weight polyethylene calendered film is a composite film prepared by combining ultra-high molecular weight polyethylene and epoxy resin. According to the bulletproof glass safety film, a composite structure and a special structural design are adopted, energy can be effectively absorbed at the moment of loading, the bulletproof capacity is high, and the ultra-high molecular weight polyethylene calendered films are not prone to being torn.

Description

technical field [0001] The invention relates to the field of bulletproof technology, in particular to a bulletproof glass safety film. 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 / polycarbonate fiber thermoplastics (usually lexan resin Also called LEXAN PC RESIN), it has the appearance of ordinary glass and the behavior of transmitting light, and provides certain protection for small arms shooting. The thickest pc board can be 136 mm thick, the maximum width is 2166 mm wide, and the effective time is up to 6664 days, bullet-proof glass is glass that has the light-transmitting and image-transmitting properties of glass, but also has the ability to protect against bullets. The bullet-proof principle of bullet-proof glass is that it can convert the impact kinetic energy of bullets into elastic potential energ...
