Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a soundproofing and vibration-proofing sheet that can be used for walls, floors, and ceilings in general houses, etc. There was no building material used for walls, floors, and ceilings in Japan that had both soundproofing and vibrationproofing properties. For example, in recent years,
Soundproofing materials that are said to be effective against noise pollution (soft soundproofing sheets made by mixing high-density materials such as lead powder into metal plates such as lead plates or synthetic resins, or cellular concrete) etc.) have been widely used, but the sound generated by impact or the sound from upstairs is transmitted downstairs accompanied by vibration.
However, it has not been possible to prevent so-called solid-borne sound.

[Purpose of the invention]

The present invention has been developed in view of the above-mentioned conventional drawbacks, and provides a soundproof and vibration-proof sheet that has both the function of blocking internal and external noise and the vibration-proofing effect against impact noise or vibration sound. It is in.

[Disclosure of the invention]

Hereinafter, the present invention will be described in detail together with all the drawings.

In the figure, J is wood, 4. 2 is a soft sound insulating sheet 3 is a resin foam, and 4 is a decorative surface material.

The wooden material 1 has many recesses 5 bored on its surface.
This recess 5 is filled with a resin foam 3 made of foamable vinyl chloride, urethane, synthetic rubber, or the like. Actual processing may be performed on both sides of the wooden material 1 to facilitate joining.

On the surface of the wooden material 10 in which the resin foam 3 is filled in the recess 5, a metal powder such as lead powder, iron powder, etc., or a high specific gravity material such as barium sulfate is added to a thermoplastic resin such as polyvinyl chloride, polyethylene, or polypropylene. Mix substances to form a specific gravity of 29 tons 1-
A soft sound insulating sheet 2 is pasted, and one side of the soft sound insulating sheet 2 is covered with a decorative surface material 4 such as a wood veneer or a patterned synthetic resin film. Adhesive is integrated.

〔Effect of the invention〕

As described above, the soundproofing and vibration-proofing panel of the present invention has a large number of recesses on the surface of a wooden material, fills the recesses with resin foam, and also has a soft sound-insulating sheet on the surface side of the main material. The soft sound insulating sheet prevents the transmission of noise, and the resin foam absorbs impact and vibration sounds, making it suitable for general residential buildings. It is useful as a soundproofing and vibrationproofing panel for walls, floors, ceilings, etc.

Claims (1)

[Claims] 1) A large number of recesses are provided on the surface of the wood material, and the recesses are filled with resin foam. At the same time, a soft sound insulation sheet is pasted on the surface side of the wood material, and a surface decorative material is also pasted. Soundproofing and anti-vibration panels that are integrated into the body.
