Title:
FORMED INTERIOR TRIM MATERIAL FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2010/029861
Kind Code:
A1
Abstract:
A formed interior trim material for vehicles is provided which includes a sheet of glass paper produced by the wet process, the glass paper having undergone a treatment for imparting satisfactory compatibility with a urethane-based adhesive and for rendering the glass paper optimal for entanglement. This glass paper has been united to a base to impart a practical flexural strength to the trim material. The trim material can be reduced in weight by using a glass-fiber reinforcement in a smaller amount than in glass mats. This interior trim material for vehicles comprises: a base layer (11) constituted of a rigid urethane; first and second glass-fiber reinforcement layers (12 and 14) respectively bonded to both sides of the base layer; a face layer (13) bonded to the outer side of the first glass-fiber reinforcement layer (12); and a back layer (15) bonded to the outer side of the second glass-fiber reinforcement layer (14). At least the first glass-fiber reinforcement layer (12) is a sheet of glass paper composed of glass-fiber filaments, which has been treated with a silane-based treating agent that comprises a silane or a mixture of a silane and a urethane emulsion.
