自動車用内装材のリサイクル方法

Document Type and Number:

Japanese Patent JP4035498

Kind Code:

B2

Abstract:

To provide a method for recycling an automotive interior material, which enables the efficient separation of a substrate from a skin material in a short time, the easy recycling of the recovered substrate and the skin material, and the inhibition of the physical deterioration and appearance failure of the recycled material.

A ceiling material 1 having a substrate 2 comprising a PS-modified PPE resin and a skin material 3 adhered to the substrate 2 is immersed in a mixture liquid 7 in which an organic solvent is contained in an excessive volume based on the volume of limonene, thus separating the substrate 2 from the skin material 3. Then, the substrate 2 is washed with an organic solvent, subjected to a centrifugally liquid-removing treatment, dried, repelletized, and then reused as a recycling material by a foaming extrusion molding method. The skin material 3 is also washed with an organic solvent, subjected to a centrifugally liquid-removing treatment, fibrillated, melt-spun and then felted to reuse as a recycling material.
