Problems solved by technology

The commonly used PVB laminated glass will have significant relative slip between two pieces of glass after being stressed, the bearing capacity is small, and the bending deformation is large. The bearing capacity is insufficient, and the whole piece will fall off when the glass is broken and then bent and deformed, and the PVB The exposed edge of the laminated glass is easy to be damp and glued, and it is easy to yellow and change color after a long time of use
[0003] At the same time, in the actual production of ionic interlayer laminated glass, static electricity will be generated after the ionic interlayer film is rubbed, which will cause various imp

Embodiment

[0019] Embodiment: The present invention provides a specific embodiment of a manufacturing method of ionic interlayer laminated glass, wherein the ionic interlayer is an ionic polymer interlayer, a copolymer of ethylene and methacrylic acid, trade name SentryGlas Plus, Referred to as SGP interlayer, it includes the following steps:

[0020] The first step, the pre-processing steps of glass, including cutting, cleaning, processing, and tempering steps:

[0021] When cutting, the cutting marks of the original film should be appropriate to obtain a good edge peeling effect, and the size should be accurate, and no difference greater than 0.5mm is allowed to avoid bubbles due to uneven edges; the edge of the glass after cutting should be ground , and then cleaned with a film processor; after cleaning, no oil and other sundries remain on the glass surface, and the cleaned glass can be used after drying and placed at room temperature, and then tempered by conventional methods.

Abstract

The invention discloses a production method of ionic middle membrane laminated glass. The method comprises the steps of earlier stage glass processing, glass lamination, and glass doping, an ionic middle membrane is an ethylene and methacrylic acid copolymer, about 1% of metal sodium ions contained are bonded with the glass by ionic bonds, the bonding strength is larger compared with the strength of PVB (Polyvinyl butyral), the shearing modulus is more than 50 times that of the PVB/PU (polyurethane), the tearing strength is 5 times higher than that of the PVB/PU, and the transparency is good.

Description

technical field [0001] The invention relates to a method for manufacturing ionic interlayer laminated glass. Background technique [0002] Ionic interlayer laminated glass is widely used in doors, windows, floors, curtain walls, ceilings and skylights of buildings. It can also be used as bulletproof glass and anti-theft glass for counters and doors and windows in business halls of banks, securities companies, insurance companies and other financial companies. , or in aerospace, glass skylights and glass windows, curtain walls, military and high-tech industries and other fields also have a wide range of applications. The ionic interlayer laminated glass reduces the thickness of the glass and reduces the amount of glass by about 40%, which also reduces the weight accordingly. Not only is it beneficial to product structure design, but material saving means energy saving, because the production of each standard box of float glass consumes 16Kg of standard coal and 7.5 degrees o...
