Problems solved by technology

However, if the plate thickness of the glass plate is reduced, there will be a problem that the sound insulation performance will be reduced.
[0003] For example, Patent Document 1 proposes that the problem of lowering the sound insulation performance can be solved by using laminated glass for the glass plate for window glass and a film having sound insulation performance (hereinafter also referred to as "sound insulation interlayer film") for the interlayer film.

Embodiment 1

[0116] Figure 11 In the laminated glass 24 whose rigidity is about 1.1 times that of the laminated glass plate whose total area of ​​the interlayer film 13 for laminated glass is the shear elastic modulus of the first region 11, it is the second value relative to the area of ​​the glass plates 75 and 76. A graph showing the relationship between the area of ​​the region 12 and the value obtained by dividing the shear modulus of elasticity of the second region against static force by the shear modulus of elasticity of the first region 11 against static force. Figure 11 Among them, the horizontal axis (x) represents the value (unit: times) after dividing the shear elastic modulus of the second region 12 to the static force by the shear elastic modulus of the first region 11 to the static force (unit: times), and the vertical axis (y ) represents the area (unit: %) of the second region 12 relative to the area of ​​the glass plates 75 and 76 , and each dot and line represents a v...

Embodiment 2

[0121] Figure 13 It is a graph showing the relationship between the sound transmission loss and the area occupied by the second region 12 in the central region B when the loss coefficients of the first region 11 and the second region 12 are the same. Figure 13 Here, the horizontal axis represents the area of ​​the second region 12 (unit: %) relative to the area of ​​the central region B, and the vertical axis represents the sound transmission loss (unit: dB). The sound penetration loss shows the value at 3150 Hz as a representative value. In addition, the value of the sound transmission loss of the usual interlayer is 32.8 dB.

[0122] In addition, the shear elastic modulus of the second region 12 is about 100 times that of the first region 11 with respect to the static force, 2 times to 7 times with respect to the sound waves of 2 kHz to 8 kHz, and the first when the sound penetrates. The calculation was performed under the condition that the loss factor of the region 11 ...

Abstract

A laminated substrate for windows, having a plurality of substrates laminated via an intermediate layer structure and having a peripheral edge area along the outer circumference of the laminated substrate for windows in the planar view and a center area on the inside of the peripheral edge area. The intermediate layer structure has a first area and a second area, in the planar view. The second area has an area ratio for the second area relative to the entire area of the laminated substrate for windows, in the planar view, that is at least (-74.87x + 204.47)% when 1.40 <= x <= 2.72 and at least (-0.0067x + 0.87)% when x> 2.72, when x is a value obtained by dividing the second area shear modulus relative to static force by the first area shear modulus relative to static force. The proportion of area occupied by the second area in the center area in the planar view is 0%-83%.

Description

technical field [0001] The present invention relates to a laminated substrate for a window, a laminated substrate for a window having a frame, an automobile provided with a laminated substrate for a window, and an interlayer structure for a laminated substrate for a window. Background technique [0002] In recent years, with the weight reduction of vehicles, the use of a thinner and lighter glass plate has been considered as a glass plate for a window glass that has been used so far. However, if the plate thickness of the glass plate is reduced, there will be a problem that the sound insulation performance will be lowered. [0003] For example, Patent Document 1 proposes that the problem of reduced sound insulation can be solved by using laminated glass for a glass plate for window glass and a film having sound-insulating properties (hereinafter also referred to as "sound-insulating interlayer film") for an interlayer film. [0004] Specifically, by providing a sound-insula...
