Abstract
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.
Claims4
Process for manufacturing vehicle headliners comprising the following stages:
- a) arranging a previously shaped three-dimensional substrate and a decorative lining;
- b) applying a layer of thermosetting adhesive 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;
- c) introducing the shaped three-dimensional substrate in a thermoforming mould at a temperature between 110 and 150° C.;
- wherein a predetermined shape of the thermoforming mould corresponds to the previously shaped three-dimensional substrate;
- d) introducing the decorative lining together with the layer of thermosetting adhesive on the shaped three-dimensional substrate such that the layer of thermosetting adhesive is in front of the shaped three-dimensional substrate;
- e) closing the thermoforming mould and applying pressure to establish the union between the decorative lining and the shaped three-dimensional substrate through the layer of thermosetting adhesive;
- f) opening the thermoforming mould and extracting the headliner.
