The present invention relates to a multi-functional vehicle interior material for effectively shielding electromagnetic waves generated from an electric vehicle and reducing indoor noise of the vehicle. The vehicle interior material of the present invention is formed of a first sound-absorbing layer, an air permeable powder adhesive layer, an electromagnetic wave shielding layer, and a second sound-absorbing protective layer, which are integrally laminated below an outer layer, and effectively absorbs vehicle noise when used as a mat inside a vehicle or in a trunk. In addition, the vehicle interior material of the present invention effectively blocks propagation of electromagnetic waves generated inside the vehicle to an indoor space, and creates a comfortable riding environment for an electric vehicle particularly which generates high levels of electromagnetic waves and continuous noise by using a high-output and high-voltage electric drive device.

    본 발명은 전기자동차로부터 발생되는 전자파를 효과적으로 차폐할 수 있고, 자동차의 내부 소음도 저감시킬 수 있는 복합기능을 가지는 자동차 내장재에 관한 것이다. 본 발명은 표피층의 하부에 제1 흡음층, 통기성 파우더 접착층, 흠읍성능이 있는 전자파 차폐층 및 제2 흡음 보호층이 일체로 적층 형성되어, 자동차 내부나 트렁크의 매트로 사용 시 차량의 소음을 효과적으로 흡음할 수 있다. 또한, 본 발명은 자동차 내부에서 발생하는 전자파가 내부공간으로 전파되지 않도록 효과적으로 차단할 수 있어, 특히 고출력, 고전압 전기구동 장치가 사용되어 높은 수준으로 전자파와 지속적인 소음이 발생되는 전기차의 안락한 승차환경을 조성하도록 유용하게 사용될 수 있다.
