The invention discloses a vehicle non-woven liner structure with an electromagnetic shielding function and a preparation method thereof.The vehicle non-woven liner structure comprises an outer layer, the outer layer is formed by combining an isolating layer, a conductive layer and an insulating layer, the isolating layer is arranged at the upper end of the conductive layer, and the insulating layer is arranged at the lower end of the conductive layer; the middle layer is formed by combining a sound absorption layer, a heat isolation layer and a waterproof layer, the sound absorption layer is arranged at the upper end of the heat isolation layer, and the waterproof layer is arranged at the lower end of the heat isolation layer. The vehicle non-woven liner with the special conductive material can effectively shield electromagnetic interference and protect stable operation of electronic equipment in a vehicle, and by reducing the electromagnetic interference, normal functions of an electronic system, including navigation and wireless communication, in the vehicle can be ensured, so that the driving safety is improved, and the service life of the vehicle is prolonged. Various functions of electromagnetic shielding, thermal isolation, sound insulation, water resistance and the like are combined, the performance level of the whole non-woven liner is improved, and a better environment is provided for riding experience.

    本发明公开了具有电磁屏蔽功能的车辆无纺衬垫结构及其制备方法,包括外面层,所述外面层由隔离层、导电层和绝缘层组合而成,所述隔离层设置于导电层的上端,所述绝缘层设置于导电层的下端;中间层,所述中间层由吸音层、热隔离层和防水层组合而成,所述吸音层设置于热隔离层的上端,所述防水层设置于热隔离层的下端。本发明具有特殊导电材料的车辆无纺衬垫能够有效屏蔽电磁干扰,保护车内电子设备的稳定运行,通过减少电磁干扰,有助于确保车辆内的电子系统,包括导航、无线通信的正常功能,从而提高驾驶安全性,结合了电磁屏蔽、热隔离、隔音、防水等多种功能,提高了整体无纺衬垫的性能水平,为乘车体验提供了更好的环境。
