A method of manufacturing a vehicle ceiling interior material capable of reducing the molding process of the vehicle ceiling interior material and the subsequent assembly man-hours, and at the same time improving the vehicle interior environment (heat insulation and sound absorption performance) for the occupant. And providing a polyurethane material suitable for it. A polyurethane foam is integrally formed with a skin, a wiring member, and the like necessary as a ceiling interior material for a vehicle. This integrally molded product substantially matches the shape of the vehicle interior side of the roof of the vehicle, and can be installed without a gap from the roof shape. This polyurethane foam is prepared from a specific polyurethane raw material, and has excellent heat insulation and sound absorbing properties as a ceiling interior material. [Selection] Figure 2 |
