일반적으로 차량의 주행 중에는, 엔진에서 발생하는 소음 및 진동음과, 도어, 헤드라이너 및 차량의 바닥 등을 통해 주행중의 소음 및 진동음이 차량의 실내 공간으로 유입된다. In general, while driving a vehicle, noise and vibration sounds generated by the engine and noises and vibration sounds while driving are introduced into the interior space of the vehicle through the door, the headliner and the floor of the vehicle.

이에, 엔진의 소음을 차단, 제진, 흡음하는 기능과 주행 중 발생하는 저주파, 고주파의 복합에너지를 차량의 실내 공간으로 전달되지 않도록 차량의 실내에 바닥재를 설치하여 왔다. 그런데, 종래의 차량용 바닥재에 있어서는, 바닥재를 이루는 표피재층 및 흡음층에 별도의 차음재를 접착제, 또는 직접코팅 하는 방법 등을 이용하여 접착하므로, 전반적으로 바닥재의 중량이 증가하여 차량의 연비가 증대될 뿐만 아니라 바닥재의 제조공정이 복잡하여 생산성이 저하되는 문제점이 있다.Accordingly, floor coverings have been installed in the interior of a vehicle so as to prevent noise, vibration, and sound absorption of the engine, and to transmit low-frequency and high-frequency complex energy generated during driving to the interior space of the vehicle. By the way, in the conventional vehicle flooring material, since the separate sound insulating material is bonded to the skin layer and the sound-absorbing layer forming the flooring material using an adhesive or direct coating method, the overall weight of the flooring material is increased to increase fuel economy of the vehicle. In addition, the manufacturing process of the flooring is complicated, there is a problem that the productivity is lowered.

The inventors have invented a vehicle flooring material which can not only reduce noise and vibration, but also simplify the manufacturing process of the flooring material, thereby improving productivity and reducing the weight of the vehicle.
