Description

The present invention relates to a sound-insulating and heat-insulating material that is excellent in sound insulation and heat insulation, has high transparency and is lightweight.

In recent years, from the viewpoint of energy saving, attempts have been made to achieve a high heat insulation effect from the outside world and to increase the efficiency of air conditioning to the limit. For this purpose, various wall materials having high heat insulation properties have been proposed.
Daylighting is extremely important when considering the living environment of a building. In the current building, it is common to install a glass window in the daylighting section, but it is difficult to exert a high heat insulating effect compared to wall materials and the like. According to the “Energy Conservation Technology Strategy Report” (June 12, 2002, Ministry of Economy, Trade and Industry), it is said that 45% of all energy consumed is lost through openings such as windows.

As glass with high heat insulation, what is called pair glass is proposed (for example, patent document 1 etc.). Pair glass is a glass with a gap between two glasses, a vacuum between the glasses, or an inert gas such as argon blown in. The presence of a space between the glasses tries to exert a high heat insulation effect. To do. However, the pair glass has a problem that it is heavier and bulky than ordinary glass. In addition, a special desiccant has been required to prevent condensation between the glasses. In addition, it costs tens of thousands to hundreds of thousands of yen / m ^{2 in} terms of cost, and is difficult to apply to ordinary houses. Furthermore, there has been a problem that the performance may deteriorate due to the intrusion of air during use for a long period of time to break the vacuum state or outgassing.

On the other hand, as a wall material used for buildings, securing sound insulation is an important issue from the viewpoint of noise countermeasures and the like. Conventionally, inorganic materials such as concrete and metal have been used as wall materials having sound insulation properties. However, although these materials are excellent in sound insulation, there is no transparency, so that daylighting is hindered. In addition, these materials are heavy and have poor effectiveness.

On the other hand, for example, when using the pair glass disclosed in Patent Document 1 etc., it is excellent in transparency, it is possible to sufficiently secure lighting, and it is lightweight and effective. Although it was excellent, there was a problem that it was inferior in sound insulation. Therefore, there has been a demand for a sound insulation and light insulation material that is excellent in sound insulation and heat insulation, has high transparency and is lightweight.
Japanese Patent Application Laid-Open No. 2003-026453

The present invention has been made in view of the above situation, and an object thereof is to provide a sound insulation and light insulation material that is excellent in sound insulation and heat insulation, is highly transparent, and is lightweight.

The present invention is described in detail below.

As a result of intensive studies, the present inventors have determined that a plurality of resin films, or a woven or non-woven fabric made of a plurality of resin fibers or glass fibers (hereinafter referred to as a resin film or a woven or non-woven fabric made of resin fibers or glass fibers). Are collectively referred to as a base material), and a sound insulation and heat insulating material having a structure facing each other across an air layer is affixed to a glass plate or a hard resin plate, or two glass plates or a hard resin plate It has been found that a high sound insulation performance can be exerted by sandwiching between the two, and the present invention has been completed.

The sound insulation daylighting insulating material of the present invention has a structure in which a plurality of resin films, or a woven fabric or a nonwoven fabric made of resin fibers or glass fibers are opposed to each other with an air layer interposed therebetween.
The sound insulation and daylight insulation material of the present invention may have a structure in which an air layer is sandwiched between two base materials (FIG. 1A), but an air layer is provided between three or more base materials. The thing of the structure clamped (FIG.1 (b)) is preferable. The sound insulation daylighting heat insulating material of the present invention having a plurality of air layers can exhibit higher heat insulation effect and sound insulation effect.

In general, as a method for reducing the propagation of sound, there are a method using a sound insulation effect that stops sound transmission and a method using a sound absorption effect that increases sound absorption. The sound insulation daylighting insulating material of the present invention can reduce the propagation of sound by using both of these effects.

The substrate preferably has irregularities on the surface. By having the unevenness, the sound insulation effect of the sound insulation daylighting heat insulating material of the present invention can be enhanced. This is thought to be because the occurrence of resonance can be suppressed by the unevenness.

The material constituting the irregularities is not particularly limited as long as it has translucency, but is preferably the same as the material constituting the spacer described later.

The method of installing only on one side of the material is mentioned.

The substrate preferably has pores on the surface. By having pores on the surface, the sound absorbing effect of the sound insulating and heat insulating material of the present invention can be enhanced. This is presumably because viscous friction is generated by the pores, and the sonic energy can be reduced.

The method of forming the pores is not particularly limited, and examples thereof include a method of perforating by a conventionally known method within a range that does not adversely affect the heat insulation.
The pores differ depending on the porosity per unit area of the base material, but when positively forming perforations, it is preferable to form perforations in the range of 10 mm ² or less in the base material. If it exceeds 10 mm ² , the strength of the sound insulation daylighting insulating material obtained may be insufficient.
When using a woven or non-woven fabric made of the above resin fiber or glass fiber, there is a conspicuous void in the base material itself, so that the effect of pores may be obtained without positively perforating. .

Can be used.
In the woven or non-woven fabric made of the glass fiber, a resin layer may be laminated on both sides or one side in a range where the visible light transmittance of the sound insulation and heat insulating material of the present invention is 20% or more.

Although it does not specifically limit as thickness of the said resin film, A preferable minimum is 10 micrometers and a preferable upper limit is 300 micrometers. When the thickness is less than 10 μm, the strength of the sound insulation and light insulation material obtained may be inferior, and when it exceeds 300 μm, the sound insulation and light insulation material may become thicker than necessary to obtain the same heat insulation effect. A more preferable lower limit is 20 μm, and a more preferable upper limit is 200 μm.

If the basis weight is less than 10 g / m ² , the strength of the sound insulation / light insulation material to be obtained may be insufficient, and the sound insulation / light insulation material may be broken by tension in the manufacturing process. If the basis weight exceeds 60 g / m ² , the translucency of the obtained sound-insulating / light-insulating material may deteriorate and the visible light transmittance may be less than 20%.

The base material may have the same thickness within the thickness range, but it is preferable that the base materials have different thicknesses. By having different thicknesses, the sound insulation can be further improved.

Since the airgel particles are excellent in translucency and have low thermal conductivity, it is possible to improve the heat insulation performance in addition to the sound insulation performance.

It is preferable that the sound insulation daylighting insulating material of the present invention has a spacer between the substrates. The spacer is used for maintaining the air layer (maintenance of the base material interval), sealing the periphery of the air layer, dividing the air layer, and the like. By having such a spacer, it is possible to impart a vibration damping effect and improve the sound insulation performance.

Moreover, a lattice-like thing is suitable for sealing the peripheral part of the air layer and dividing the air layer. Furthermore, you may provide the design property to the sound insulation daylighting heat insulating material of this invention with the shape of the said spacer. In addition, in the sound insulation daylighting insulating material of the present invention, when there are a plurality of the air layers, the spacers constituting each air layer may have the same shape or different shapes. For example, the spacers may be in a lattice shape as a whole by arranging the linear spacers constituting the adjacent air layers so as to be orthogonal to each other.

When the spacer is particulate, the number of the particulate spacer per unit area is not particularly limited, but a preferred lower limit per layer is 80 / m ² .
