Example Embodiment
[0023]The technical solutions of the present invention will be further described below with reference to the accompanying drawings.
[0024]This embodiment provides a method of fabricating a vehicle atmosphere, comprising the steps of:
[0025]Step (1): Leather substrate 1 is formed.
[0026]Taking a model car pepper as an example, the size is 1982mm × 1272mm, the weight is 2850g, such asfigure 1 As shown, the topic substrate 1 mainly includes a nonwoven fabric, a glass fiber, and a polyurethane sheet 13, and both side rolls coating MDI glue (the amount of glue is 80 g / m) of the nonwoven fabric.2) And sprayed softening water, the first nonwoven fabric 11, the first glass fiber 12, the polyurethane sheet 13, the second glass fiber 14, and the second nonwoven fabric 15 are in turn laid into the formation. Specifically, the substrate 1 is placed in a molded mold, and the upper mold temperature of the molding die is 115 ° C, the lower die temperature is 85 ° C, the pressure is 9 MPa, and the m...
