RE-PEELABLE LAMINATE AND RE-PEELING METHOD THEREFOR |
| 摘要 |
PROBLEM TO BE SOLVED: To re-peel a bonded panel, which is formed by bonding a decorative metal panel to a porous board, without breaking the same to achieve the recycling of materials. SOLUTION: The decorative metal panel being a surface material is bonded to the porous board being a base material by using (A) an aqueous dispersion containing a polymer forming a film with a tensile force of 1-28 MPa and an elongation of 100-2,000% after drying and (B) an aqueous adhesive composition comprising thermally expansible fine hollow particles as adhesives to form the bonded panel being a laminate. The bonded panel is irradiated with far infrared rays in a heated atmosphere to re-peel the bonded panel being the laminate.
