- greaves sheet, cushioning, skin material and parison A fiber sheet, a foam sheet, a known backing material, or the like can be laminated to prevent air accumulation between them and the like, and to improve the adhesion strength between the skin material and the parison.
- nonwoven fabrics having a weight per unit area of lOOgZm 2 or more made of synthetic fibers having polyester, polypropylene or polyamide strength are particularly preferred from the viewpoint of moldability.
- the skin material is mainly attached to the surface wall of the surface wall and the back surface wall constituting the plate-shaped main body, a skin material having a non-woven strength is applied to both the surface wall and the back surface wall. By sticking, it is also possible to cover the entire surface with a skin material so that the plate-shaped main body is not exposed.
- at least one of the skin materials to be adhered to both the front wall and the back wall, in particular, the skin material to be adhered to the back wall is reinforced with a bending elastic modulus of 2100 MPa or more and a thickness of 1. Omm or less. It can be a sheet or a non-woven fabric having a breaking strength of 90 kg / m 2 or more.
- blow molding refers to a mold in which a cylindrical Norison or a plurality of resin sheets are melt-extruded or pre-formed resin sheets are heated and melted and placed between split molds. So-called direct blow molding or sheet blow molding, which is formed into a desired shape by tightening, is a question of whether or not air blowing is involved!
- the present invention has a front wall and a back wall produced by blow-molding a thermoplastic plastic, and at least between the front wall and the back wall, the front wall and the back wall are respectively located on the hollow portion side.
- the present invention relates to a panel-shaped automotive interior product having ribs integrally welded to the inner surface and a method for manufacturing the same.
- the automobile interior product according to the present invention is used for a cargo floor panel (a cover panel or luggage board of an automobile luggage compartment) or a rear parcel shelf.
