Automobile sound insulation materials are designed according to automobile noise. Automobile sound insulation material is mainly butyl rubber, which belongs to environmental protection damping sheet, rubber and plastic, EVA/EPDM board, etc.
Automobile sound insulation materials should be light, moisture-proof, waterproof, corrosion-resistant, moth-proof and not easy to mold. They do not contain harmful substances such as asbestos, glass fiber and heavy metal lead. And the sound insulation materials should be analyzed in detail, and different sound insulation materials should be selected according to different positions of the car.
For automobile sound insulation, five materials are usually used:
1. Damping, sound insulation and anti-vibration pad
2. Shock absorption, sound insulation and sound absorption cotton
3. Hood soundproof cotton
4. Sandwich sound insulation and absorption cotton
5. White cotton (automotive interior sound-absorbing cotton)
Choose the appropriate materials according to the construction site, such as making the chassis, doors and fenders sound-proof, and using shock-absorbing sound-absorbing pads and sound-absorbing cotton. Cover cotton is used for cover sound insulation, and sandwich sound-absorbing cotton is used for firewall sound insulation. If the cost performance is considered, the anti-vibration pad can be partially pasted, as long as all cotton is pasted. Because the door is the secondary part of the sound insulation part of the whole vehicle, the main part is the cockpit floor and trunk. If these two parts are done, make sure to cover the vibration pad and sound insulation cotton.
