The present invention relates to interior and exterior materials for an automobile and a manufacturing method thereof, wherein in a state of coupling glass mats (16, 18) to upper and lower portions of an intermediate substrate (14) manufactured to have a space portion (12) with expanded polypropylene, foamed polystyrene, or the like, a body (24) is foam-molded using polyurethane (20, 22) to bond surface paper (26, 28) to one surface or both surfaces of the body (24). Therefore, required and enough strength can be provided, and a weight of the interior and exterior materials for an automobile can be lightened. Moreover, size stability is secured, and strength with respect to moisture can improve the utility value of a product.
본 발명은 자동차용 내,외장재 및 그 제조방법에 관한 것으로, 발포폴리프로필렌이나 발포폴리스티렌 등을 이용하여 공간부(12)를 갖도록 제작된 중간기재(14)의 상하에 글라스매트(16)(18)를 결합한 상태에서 폴리우레탄(20)(22)을 이용하여 본체(24)를 발포성형한 다음 상기 본체(24)의 일면 또는 양면에 표면지(26)(28)를 접합형성하여 구성함으로서, 요구되는 충분한 강도를 지닐 수 있도록 하면서 경량화하고 또 치수안정성을 보장해줄 수 있도록 하며, 수분에 강해 제품의 이용가치를 높여줄 수 있도록 한 것이다.
