合わせガラス用中間膜及び合わせガラス
Document Type and Number:
Japanese Patent JP7280830
Kind Code:
B2
Abstract:
Provided is an interlayer film for laminated glass having increased tanδ and excellent sound insulating property in an interlayer film having a low glass transition temperature. An interlayer film for laminated glass according to the present invention includes a resin layer containing a resin component and a plasticizer, and combination of the resin component and the plasticizer in the resin layer is such that when a composition having a glass transition temperature of -10°C is obtained by blending only the plasticizer in 100 parts by weight of the resin component, a blending amount of the plasticizer per 100 parts by weight of the resin component in the composition is 60 parts by weight or less, and the interlayer film satisfies the formula: tanδ1 ≥ 1.3, or satisfies the formula: (tanδ0 - tanδ1)/(Tg0 + 10) ≤ 0.01.
