Pre-fracture belt escape glass, manufacturing method of pre-fracture belt escape glass and application of pre-fracture belt escape glass to high-speed railway escape window glass

Abstract

The invention discloses pre-fracture belt escape glass, a manufacturing method of the pre-fracture belt escape glass and the application of the pre-fracture belt escape glass to high-speed railway escape window glass. A round point is buried between two layers of laminated glass in advance and is made of rubber containing high-hardness materials, a thermoplastic TPS rubber strip is buried within the range 2-10 cm away from the edge of the laminated glass and on the periphery of the laminated glass to serve as a pre-fracture belt, a fracture is formed in the pre-fracture belt to serve as a rubber injecting overflow opening, and the part within the range 10 mm away from the edge of the glass is coated with a TPS sealing ring. The rubber round point containing the high-hardness materials is buried between the two layers of the laminated glass in advance, after the glass is knocked, the internal ultra-hard materials are pressed by the instant knocking pressure, and the front piece and rear piece of glass are broken simultaneously. The thermoplastic TPS rubber strip is buried on the periphery of the glass to serve as the pre-fracture belt, and after the glass is broken, the glass is likely to be cut into two parts from the fracture belt, so that a knocker can push the glass open from the pre-fracture line easily and escape through a glass window.

Description

technical field [0001] The invention relates to an escape glass, in particular to an escape glass with a pre-fracture zone, its manufacturing method and its application on the escape window glass of high-speed rail. Background technique [0002] The deficiencies and defects of the glass used for escape function in traditional crafts: when an escaper wants to escape in an emergency, the window glass cannot be smashed at one time. Excluding the factors of the knocker's knocking method, glass structure defects (laminated glass composed of two layers of glass, after one side is broken, it needs to pass through the middle layer and then break the other side). It takes too long for the glass to be broken (the intermediate bonding layer or the peripheral bonding layer must be destroyed to achieve it, which takes a long time to achieve), which delays the escape time and increases the danger of escapers being trapped After the traditional escape window glass is knocked and broken, t...

[0002] The deficiencies and defects of the glass used for the escape function in the traditional craft: when an escaper wants to escape in an emergency, the window glass cannot be smashed at one time

It takes too long for the glass to be broken (the intermediate bonding layer or the peripheral bonding layer must be destroyed to achieve it, which takes a long time to achieve), which delays the escape time and increases the danger of escapers being trapped ; After the traditional escape window glass is knocked and broken, the whole body directly falls off the vehicle frame, and the heavier glass will smash the escape personnel, causing secondary damage to the escape
