Abstract

<P>PROBLEM TO BE SOLVED: To make it possible to get a vacuum layer easily since the clearance between a metal or a synthetic resin board, carried out vacuum packing, can be used as the vacuum layer as both sound isolation and heat insulation. <P>SOLUTION: A spacer is placed between two synthetic resin boards, which is put into one bag of aluminum laminate film and its inside is made to the vacuum. It is a thin light vacuum sound isolation heat insulation panel. Metal or synthetic resin boards are combined using the bag of the aluminum laminate film 1 and the vacuum layer can be made easily by putting the spacer in-between. The ultrathin/ultralight vacuum layer is applied for sound isolation/heat insulation. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

The present invention relates to a thin and lightweight soundproof heat insulating plate used for a soundproof door for a house, a panel, an industrial soundproofing work, and the like.

Vacuum is to say that it is not also conveyed heat is also sound, had been well known, and with the application of an architectural member atmospheric pressure also takes 10 tons of 1m ^2, not compelling thick plate thickness, creating a planar body It was difficult and heavy, and could not be put to practical use.

Problems to be solved by the invention

Listening to music and performing music is a way to enjoy the world of hobbies, such as a space, and that's why you shouldn't leak sound to your neighbors. There is no current situation. Making a loud sound is a source of neighbor troubles, especially at night, and loud sounds at night are annoying and must be self-sufficient. In such cases, it is desirable to use lightweight, high-performance soundproof panels.
As a soundproofing technique, there is a law of mass measurement, and if there is no weight to some extent, the sound will not decrease. In fact, one high-performance soundproof door is 200 kg in weight and 200 mm thick. The present invention utilizes a technology that uses a light plastic plate and does not transmit sound waves in a vacuum, and a lightweight (1 m ² * 860 g) plastic plate can be used to create a vacuum layer to produce a high-performance soundproof door. Although it is not free of defects, it has weak points such as being unable to cut or puncture, but because it is vacuum, it also has high performance heat insulation performance compared to conventional heat insulation materials.

Means for solving the problem

We develop high performance / soundproofing materials / insulation materials that have both high-performance vacuum insulation performance and vacuum soundproofing performance, lightness that can be installed anywhere, and thinness that can be installed anywhere. In order to form a vacuum layer, pyramid type or spherical spacers with a small contact area are arranged finely so as not to lose the pressure of atmospheric pressure so as not to lose the vacuum stress. Moreover, it is an object to be exhausted by wrapping it in an aluminum laminate film that does not need to be welded so that a vacuum layer can be easily obtained.

The invention's effect

The insulation / sound insulation is thin, light and high performance. This heat insulating material / soundproofing material has the same performance as a vacuum heat insulating material, and is excellent in soundproofing effect because it is a vacuum.
In the vacuum, it takes advantage of sound and heat.

Here, two polycardnate plates (910 * 1820 * 2t) are combined, and a sharp resin with poor heat conductivity (0.5 mm to 2 mm) is inserted between them as a spacer. This is put into a bag of highly airtight aluminum laminate film, evacuated, sealed with a sealer, etc. to produce heat insulation and soundproofing materials. Each thickness is made of polycarbonate 2.0t * 2 spacers 2.0t (

The ultra-thin soundproofing / insulating material produced above has a vacuum layer of 2 mm, so it can be used as both a heat insulating material and a soundproofing material.

Instead of using a spacer, a spacer that becomes a protrusion from the time of molding the resin plate may be molded from the beginning. It doesn't matter how you make the space.

In addition, by creating a space (interference space) for the required soundproof performance, the thickness of the conventional soundproofing material has led to narrowing the room and not enough space. Can create a space.

Replacing the resin with a metal plate such as an aluminum plate can provide equivalent performance. In this case, the production unit cost can be selected by changing the material, so that an inexpensive / easy to process product can be selected.

Thus, it is a high performance soundproofing / insulating material that can easily cope with the required performance, cost and thickness.

We can provide ultra-thin soundproofing / insulation material with a light weight of 6mm, and you can select the desired soundproofing / insulation performance by thickness. As a result of improving the desired soundproofing / heat insulation performance, it can be applied as a lightweight, thin soundproofing / heat insulation material.

Claims (2)

Two metal plates (aluminum, stainless steel, iron, etc.) or synthetic resin plates (polycarbonate / acrylic plate 2t to 5t glass plate) are placed facing each other with a minute space. A space is put in the space so that the two plates and the periphery do not adhere closely, and the space is wrapped with an aluminum laminate film bag, and the inside is reduced by a vacuum pump and sealed. The two synthetic resin plates are vacuum soundproof and heat insulating panels characterized in that a vacuum layer is formed by the thickness of the spacer without being in close contact with each other. It is a soundproof and heat insulating panel characterized in that spacers (pyramid type, spherical shape) are arranged on opposing surfaces so that two plates are in point contact.
