Abstract
A door trim including a base and a skin firmly bonded via a non-reactive hot melt adhesive layer with less dependence on the material forming bonding surfaces, and a method for manufacturing the door trim are provided. This door trim includes a base and a skin bonded to a surface of the base. A bonding surface of the base to the skin includes a region made of polyolefin and/or a region made of polyurethane. A bonding surface of the skin to the base is made of polyolefin. The bonding surfaces are bonded via a non-reactive hot melt adhesive layer containing acid-modified polyolefin.
Claims24
A door trim comprising:
- a base;
- and
- a skin bonded to a surface of the base, wherein
- the base has a bonding surface S to the skin, the bonding surface S including a region S1 having no polar group and/or a region S2 having a polar group,
- the skin has a bonding surface T to the base, the bonding surface T being bonded with the bonding surface S via a non-reactive hot melt adhesive layer, and
- the non-reactive hot melt adhesive layer contains acid-modified polyolefin.
A method for manufacturing a door trim comprising a base and a skin bonded to a surface of the base, the base having a bonding surface S to the skin, the bonding surface S including a region S1 having no polar group and/or a region S2 having a polar group, the skin having a bonding surface T to the base, the method comprising:
- bonding the bonding surface T with the bonding surface S using a non-reactive hot melt adhesive containing acid-modified polyolefin.
