の充填剤を混和させてシート状に成形されている。Means for Solving the Problems The asphalt sheet for vehicle vibration isolation according to the present invention has an asphalt material as its main component, to which a porous, granular ceramic material is added as a lightening agent, and other fillers are mixed therein. It is formed into a sheet shape.
作用
このアスファルトシートではアスファルト材に混入する
粒状のセラミック材がポーラスで極めて軽量なものであ

揮できるようになる。Function: In this asphalt sheet, the granular ceramic material mixed into the asphalt material is porous and extremely lightweight, so even if other necessary fillers are added, the entire asphalt sheet can be made relatively lightweight, and it is also able to withstand vibrations. As a result, vibration energy can be efficiently absorbed in the form of internal loss due to friction generated between other materials and the void, and a sufficient vibration damping effect can also be achieved.

ている。The asphalt sheet described in the example section is placed under the interior floor of the car end or under the floor of the trunk room for vibration and corrosion prevention purposes.It is made of asphalt material as its main component and granular ceramic material as a lightweight agent, as well as this material. By adding other necessary fillers, it is formed into a sheet of desired thickness.

%, blown asphalt 20-3059 granular ceramic material 10-20%, waste paper 3-5%, mica of about 20 meshes 10-25%, butadiene rubber 1-5%, talc 5
Can be mixed at ~20%, preferably straight asphalt 25%, blown asphalt 29%, mica 12
%1 Granular ceramic material 12%, waste paper 3%, talc 15%
, butadiene rubber at a ratio of about 4%, and mica at a ratio of about 12%. These compositions may be heated and mixed well, then calendered to form a sheet with a thickness of about 165 to 3 mm, cooled, and then cut into a predetermined shape to fit the surface on which it will be laid.

振性も極めて良好なものになる。The asphalt sheet obtained in this way is lightweight as a whole because the mica is partially replaced with a porous and granular ceramic material, and the ceramic material absorbs vibration energy through internal friction. The vibration isolation properties are also extremely good.

料に形成することを可能にするものである。Incidentally, it is 1.8 for straight asphalt 15%, blown asphalt 31%, asbestos 15%, and talc 39%.
When compared with a conventional asphalt sheet formed to a thickness of ~2 mm, it was found that the asphalt sheet according to the present invention has a specific gravity that is approximately 10 to 15% lower and vibration damping properties that are improved by 50 to 70%. As described above, according to the asphalt sheet for vehicle vibration isolation according to the present invention, by adding porous and granular ceramic material as a lightweight agent, it is possible to form a sheet material that is lightweight and has excellent vibration isolation properties. It is what makes it possible.
