The bullet-proof glass has the thickness of 18-24 mm, the light transmittance of 85%-90%, good flame resistance and good heat-insulation sound-insulation performances, is capable of resisting the impact of three continuous bullets emitted from a position with a distance of 10 m by a 79 type 7.62mm submachine gun, has high explosion-proof performance, and is capable of effectively preventing bullets from passing through the glass and preventing secondary damage to human body.
Description
Technical field
The present invention relates to a kind of light-duty, bulletproof glass of splashing without fragment, belong to the special glass technical field.
Background technology
Bulletproof glass is a kind of compound material obtained through special processing by glass (or lucite) and high-quality engineering plastics, and the bulletproof glass that different vendor produces is different.But be all to press from both sides the makrolon material layer in common glassy layer basically, this process is called lamination.In this process, formed a kind of similar simple glass but than simple glass thicker material.Merlon is a kind of rigid transparent plastic.The thickness of bulletproof glass is between 7 millimeters to 75 millimeters.The bullet of penetrating on bulletproof glass can puncture outer field glass, but the Merlon glass material layer can absorb the energy of bullet, thereby stops it to penetrate the glass internal layer.The bulletproof glass of these bulks is being done public purposes during World War II, usually thickly reaches 10.0 centimetres to 12.0 centimetres, and extreme heavy.
CN1690005A discloses a kind of manufacture method of high strength bulletproof laminated glass, polycarbonate membrane is glued between two adhesion films, after forming a reinforcement diaphragm, then utilize the nanometer viscose glue to be adhered between two glass sheets to form laminated glass on this reinforcement diaphragm.CN101961943A discloses a kind of manufacture method of light-duty bulletproof glass, superimposed according to the order of former of former of face glass, polyurethane pellicle, methacrylate sheet, polyurethane pellicle, back-panel glass.
Although above-mentioned bulletproof glass is lightweight, thin thickness but as the special-purpose bulletproof glass of specific use, its light transmittance, sound deadener/insulator are poor, and the situation that exists fragment to splash, and are not suitable for the fields such as aviation, ground forces' main battle weaponry.
Summary of the invention
The purpose of this invention is to provide a kind of light-duty, bulletproof glass of splashing without fragment.
