INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS |
摘要 |
The present invention provides an interlayer film for a laminated glass which can suppress bubble formation and bubble growth in the laminated glass. An interlayer film 1 for a laminated glass includes a first layer 2 and a second layer 3 laminated on one face 2a of the first layer 2. Each of the first layer 2 and the second layer 3 contains a polyvinyl acetal resin and a plasticizer. In the case of measuring viscoelasticity of a resin film (glass transition temperature: Tg(° C.)) formed from the first layer 2 or a resin film (glass transition temperature: Tg(° C.)) formed with 100 parts by weight of the polyvinyl acetal resin contained in the first layer 2 and 60 parts by weight of a plasticizer of triethylene glycol di-2-ethylhexanoate (3GO), the resin film has an elastic modulus of G′(Tg+80) at (Tg+80)° C. and an elastic modulus of G′(Tg+30) at (Tg+30)° C., and provides a ratio (G′(Tg+80)/G′(Tg+30)) of 0.65 or higher. |
