Problems solved by technology

[0004] The PVB film and SGP film used to bond two pieces of glass in the existing gradient laminated glass can make the glass fragments still adhere to the intermediate laminated film when the glass is broken, and the broken glass surface remains clean and smooth , to ensure personal safety, and has the advantages of blocking infrared and ultraviolet rays, but the PVB film and SGP film have a poor blocking effect on sound waves, and the sound insulation effect is poor, and the PVB film is relatively soft and has a small shear modulus, which makes laminated glass. Reduced bearing capacity
