Abstract

A laminated glass including two facing glass plates and an interlayer film disposed between the two glass plates. The interlayer film has a resin layer having a storage modulus of 1000 MPa or more at a temperature of 25° C. and a frequency of 1×10 5 Hz. The laminated glass may be a windshield for an automobile.

Claims (13)

1 . A laminated glass for a vehicle, comprising:

two facing glass plates; and

an interlayer film disposed between the two facing glass plates, wherein the interlayer film comprises a resin layer having a storage modulus of 1000 MPa or more at a temperature of 25° C. and a frequency of 1×10 5 Hz.

2 . The laminated glass according to claim 1 , wherein the two facing glass plates comprise a first glass plate and a second glass plate that is thicker than the first glass plate, and wherein the resin layer is adjacent to the second glass plate.

3 . The laminated glass according to claim 1 , wherein the laminated glass is a windshield for an automobile.

4 . The laminated glass according to claim 1 , wherein the resin layer has a storage modulus of between 1000 MPa and 7000 MPa at the temperature of 25° C. and the frequency of 1×10 5 Hz.

5 . The laminated glass according to claim 1 , wherein the resin layer has a storage modulus of between 1200 MPa MPa and 7000 MPa at the temperature of 25° C. and the frequency of 1×10 5 Hz.

6 . The laminated glass according to claim 1 , wherein the resin layer comprises a thermoplastic resin.

7 . The laminated glass according to claim 6 , wherein the resin layer further comprises a plasticizer, and a content of the plasticizer in the resin layer is less than 18% by mass based on an amount of the thermoplastic resin.

8 . The laminated glass according to claim 7 , wherein the plasticizer consists of triethylene glycol di(2-ethylhexanoate).

9 . The laminated glass according to claim 7 , wherein the plasticizer consists of a single resin layer.

10 . The laminated glass according to claim 1 , wherein the two facing glass plates comprise a first glass plate and a second glass plate, and wherein the resin layer is located adjacent to and in contact with the second glass plate.

11 . The laminated glass according to claim 10 , wherein the second glass plate is thicker than the first glass plate, and wherein the resin layer is additionally located adjacent to and in contact with the first glass plate.
