According to the present invention, provided is lightweight insulation for a vehicle, having a foamed synthetic resin layer such as foamed polypropylene (EPP) which is inexpensive and has excellent formability, and a polyurethane layer, and thus, it is possible to produce the lightweight insulation which is lightweight and can be manufactured inexpensively. Particularly, it is possible to easily produce insulation having a complex shape, and thus, the insulation can be used conveniently. In addition, according to the present invention, provided is lightweight insulation for a vehicle, having a three-layer structure in which a formed synthetic resin layer is formed between two polyurethane layers, and thus, it is possible to further increase noise-prevention properties while minimizing an increase in the weight of the insulation. Moreover, according to the present invention, the foamed synthetic resin layer is at least partially formed on the polyurethane layer or sound-absorbing holes penetrate the foamed synthetic resin layer partially or entirely, and thus, the insulation may be light and inexpensive while having further increased sound-absorbing properties.

    본 발명은 저렴하면서도 성형성이 우수한 발포폴리프로필렌(EPP)과 같은 발포 합성수지층과 폴리우레탄층으로 구성함으로써, 가벼우면서도 저렴하게 제작할 수 있고, 특히 복잡한 형상의 인슐레이션도 쉽게 제작하여 편리하게 사용할 수 있게 한 자동차용 경량 인슐레이션을 제공한다. 또한, 본 발명은 두 개의 폴리우레탄층 사이에 발포 합성수지층을 구성하는 3층 구조로 제작하므로, 중량 증가를 최소화하면서도 소음 성능을 더욱 높일 수 있게 한 자동차용 경량 인슐레이션을 제공한다. 그리고 본 발명은 발포 합성수지층을 폴리우레탄층에 적어도 부분적으로 구성하거나, 발포 합성수지층에 부분적이나 전체적으로 흡음 홀을 관통 성형하므로, 가볍고 저렴하면서도 흡음 성능을 더욱 높일 수 있게 한 자동차용 경량 인슐레이션을 제공한다.
