Definitions
- the present invention relates to compositions based on plasticized polyvinyl chloride (PVC) thermoplastic resins, allowing the production of a layer of "skins" composites or multilayers; these skins or composite structures comprise an outer coating or coating and an inner layer according to the invention; these composite skins are used for passenger compartment parts of motor vehicles, such as in particular instrument panels equipped with visible airbags (with separate flaps) or integrated airbags (also known as airbags invisible to the driver and passengers), central consoles and door trim (or door panels).
- PVC plasticized polyvinyl chloride
- the invention also relates to the process for manufacturing these composite skins by molding.
- Prior art :
- dashboards It is known in the technical field of manufacture of the dashboard of a motor vehicle, to use the skins thereof conventionally made in particular by the hot-powder powder flow molding technique, either by rotational molding or by "slush -moulding "or slugging.
- These dashboards generally include an external "skin” imitation leather that gives the appearance (especially the color, the pattern, the appearance to the touch); typically the main materials used are thermoplastic resins of polyvinyl chloride (PVC), thermoplastic polyurethanes (TPU), thermoplastic polyolefins (TPO), and polyurethanes (PU).
- a foam-based material usually made of polyurethane or expanded PVC, is used as a sub-layer to provide flexibility properties and sound and thermal insulation.
- a “skin” composite (multilayer) can be made to provide particular properties of appearance, in particular: decoration, color, touch or resistance to aging, or abrasion.
- IMC In Mold Coating
- a key problem that arises is the migration of the plasticizers contained in the PVC layer through the coating, resulting in their exudation which gives a greasy feel to the outer surface of the coating. skin and an unsightly appearance, especially for dashboards of motor vehicles; another problem encountered may be the incompatibility between the various additives, such as plasticizers in particular, used in the PVC layer and in the coating.
- Another problem encountered is the migration of amines from the polyurethane into the PVC layer. To limit the migration in the polyurethanes, the crosslinking can be increased but then the properties are reduced at low temperatures.
- plasticizers used are chosen from esters formed from higher (typically C.sub.1-C.sub.13) alcohols and from organic acids such as in particular aromatic acids such as trimellitic acid to give trimellitates (for example octyl-TMO trimellitate), phthalic acid to give phthalates (for example dibutyl phthalate-DBP, dioctyl phthalate-DOP, diundecyl phthalate-DUP, ditridecyl phthalate-DTDP) or benzoic acid (benzoates); other acids such as in particular adipic acid (dioctyl adipate-DOA, diisodecyl adipate-DIDA, ditridecyl adipate (DTDA), oleic acid (butyl oleate), sebacic acid (dioctyl sebacate), DOS, diisodecyl sebacate-DIDS), azelic acid (dioc
