PROCESS FOR MANUFACTURING VEHICLE HEADLINERS

摘要

Manufacturing process for vehicle headliners comprising a substrate and at least one decorative lining extending along one of the faces of said substrate, joined to each other through a layer of adhesive, which specifically comprises the union of the decorative lining to the previously shaped substrate using a thermosetting adhesive with a high viscosity.

1. Process for manufacturing vehicle headliners comprising the following stages:
a) arranging a previously shaped substrate (2) and a decorative lining (1); b) applying a layer of thermosetting adhesive (3) with a Brookfield viscosity between 1000 and 2500 mPa s measured at 25° C. with a no. 3 spindle and rotational speed of 20 rpm on the decorative lining (1); c) introducing the shaped substrate (2) in a thermoforming mould (5) at a temperature between 110 and 150° C.; d) introducing the decorative lining (1) together with the layer of thermosetting adhesive (3) on the shaped substrate (2) such that the layer of thermosetting adhesive (3) is in front of the shaped substrate (2); e) closing the thermoforming mould (5) and applying pressure to establish the union between the decorative lining (1) and the shaped substrate (2) through the layer of thermosetting adhesive (3); f) opening the thermoforming mould (5) and extracting the headliner (10).
