る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulator for a vehicle, and more particularly to a low-noise type hood insulator for a vehicle complying with the 2002 National Noise Regulations.
【０００２】[0002]

Description of the Related Art In recent years, social demands for automobile noise have become strict, and noise regulations for automobiles, especially large vehicles such as trucks, have been tightened. The current noise regulations are large and medium-sized vehicles 83 dB (A), In contrast to the 78 dB (A) for small cars, the domestic noise regulations for 2002 include 80-82 dB (A) for large / medium cars and 76 dB (A) for small cars. In addition, the above-mentioned noise value is obtained during actual driving (0 → 80k
(at m acceleration running) at a certain measurement point.

さない方法として、吸音材の吸音特性の向上を図ること
が特に注目される。[0003] Therefore, a noise reduction technology of 1 to 3 dB (A) is required. As a noise reduction technology, measures such as improving the sound absorbing properties of the sound absorbing material, and improving the sound insulating properties by closing the gap of the shielding cover, etc. can be considered.However, as a method that does not affect other performances, there is a method of improving the sound absorbing properties of the sound absorbing material. Of particular interest is the improvement.

た。[0004] As a measure for improving the sound absorbing characteristics of this sound absorbing material,
Optimization of the surface covering material and the sound absorbing base material, securing of the back air space, mounting structure of the sound absorbing material, and the like can be considered. Then, the present inventor first tried countermeasures such as increasing the thickness of the glass wool as the sound absorbing base material, increasing the surface density of the glass wool, and increasing the installation area of the glass wool.
【０００５】ところが、グラスウールの厚手化について

能の向上には至らなかった。However, regarding the thickening of glass wool, the sound absorption performance is greatly affected by the thickness.
Although sound absorption performance can be ensured, the installation space for the sound absorbing material around the engine is limited, and it is necessary to reduce the thickness as much as possible. Next, regarding the increase in the surface density of the glass wool, the desired effect was not obtained because the influence on the sound absorbing performance was small as compared with the thickening.
Furthermore, as for the increase in the installation area of the glass wool, since the place where the glass wool can be installed has already been treated, the sound absorbing performance was not further improved.

The substrate is an organic solvent-based or water-soluble adhesive such as 5-20.
g / m 2 and adhered. Incidentally, the backing material, exhibits an effect by 0.3～0.5M 2 placed against the product 1 m 2. The reason is that the backing material needs to be installed at the top of the cylinder block of the lowest engine (the back of the bonnet). In the present invention, the reason why the average fiber diameter of the short glass fibers constituting the backing material is set to less than 2 μm is that the high-frequency (2000 to 4000 Hz) sound absorbing performance is excellent. The surface covering material has a thickness of 0.2 to 10
It is made of a metal foil such as an aluminum foil having an area density of 15 to 150 g / m 2 , an organic fiber non-woven fabric such as a Kansaisha, an inorganic woven fabric such as a glass cloth, or the like, and is adhered to a substrate at the same time or in a later step. When the insulator of the present invention is installed around the engine of an automobile, it is preferable that the back air layer on which the backing material is arranged has a thickness of about 3 to 20 mm.

のである。In order to use the insulator 3 of the present invention, for example, as shown in FIG. 3, a cover material 4 for covering the surface of the base material 1 of the insulator 3 on the back of the hood 6 and on the upper part of the engine 7. The backing material 2 in which the ultrafine glass short fibers are laminated on the back air layer 5 formed by the hood 6 and the base material 1 corresponds to a predetermined location, for example, the cylinder block 8 of the engine 7. In this case, low-frequency noise from the engine 7 is absorbed by the low-frequency sound absorption characteristics of the base material 1, and reaches the backing material 2 from the engine 7 via the back air layer 5. High-frequency noise is absorbed by the high-frequency sound absorption characteristics of the backing material 2. As a result, the noise radiated to the outside can be reduced due to the synergistic effect of the sound absorbing properties of the base material 1 and the backing material 2. The cover material 4 is provided for covering and protecting the surface of the substrate 1.
