Production method of ionic middle membrane laminated glass

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...

AI Technical Summary

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 impurities to be adsorbed on the ionic interlayer film. Although these impurities will not affect the service life of the glass. But It greatly affects the appearance quality and cannot meet the needs of high-end customers. At the same time, the film cutting angle and force cause shrinkage after pre-compression, and because the head absorbs more heat, the furnace temperature drops more in a short time and advances at a constant speed. The glass tail may not be able to absorb enough heat, resulting in insufficient edge sealing and large-area air bubbles, especially in continuous production, which leads to the scrapping of the original ionic interlayer film
