Description

Novel laminated glass

Technical Field

The utility model belongs to the technical field of laminated glass, concretely relates to novel laminated glass.

Background

The laminated glass is a composite glass product which is formed by two or more pieces of glass, wherein one or more layers of organic polymer intermediate films are sandwiched between the two or more pieces of glass, and the glass and the intermediate films are permanently bonded into a whole after special high-temperature prepressing (or vacuumizing) and high-temperature high-pressure processing. The interlayer film conventionally used for laminated glass may be: PVB, SGP, EVA, PU, and the like.
