The present invention relates to interior and exterior materials for an automobile. The interior and exterior materials for an automobile attach partial blocking papers (32, 40, 42, 44) on an upper part or upper and lower parts of an honeycomb (12) having a space part (34), and delay a penetration rate of the polyurethane (18, 20) to the honeycomb (12) when the polyurethane (18, 20) is supplied for conducting foam molding of a main body (22), thereby minimizing a using amount of the polyurethane (18, 20). Also, The interior and exterior materials for an automobile make a sufficient amount of the polyurethane (18) for being coupled to the honeycomb (12) exist on an upper glass mat (14), thereby preventing occurrence of defects due to lack of the polyurethane (18) during the foam molding of the main body (22).

    본 발명은 자동차용 내,외장재에 관한 것으로, 공간부(34)를 갖는 허니컴(12)의 상부 또는 상하에 부분차단지(32)(40)(42)(44)를 부착형성하여 본체(22)의 발포성형을 위한 폴리우레탄(18)(20)의 공급시 허니컴(12)에 대한 폴리우레탄(18)(20)의 침투속도를 지연시켜서 폴리우레탄(18)(20)의 사용량을 최소화하면서 상부글라스매트(14)에도 허니컴(12)과의 접합을 위한 충분한량의 폴리우레탄(18)이 존재하도록 하여 본체(22)의 발포성형시 폴리우레탄(18) 부족에 의한 불량발생을 방지해줄 수 있도록 한 것이다.
