Polyolefin resin foam particles, foam-particle moulded body, and composite stacked body including said moulded body

摘要

The present invention provides polyolefin resin foam particles, i.e. multilayer foam particles each comprising: a core layer which is in a foamed state, and which is configured from a polyolefin resin; and a coating layer with which the core layer is coated. The coating layer is configured from a mixed resin including a polyolefin resin (A) and at least one resin (B) selected from polystyrene resins and polyester resins. The weight ratio (A:B) of the polyolefin resin (A) to the at least one resin (B) in the mixed resin is in the range of 15:85 to 90:10. The present invention also provides a composite stacked body in which a foam-particle moulded body of said polyolefin resin foam particles is used. The foam-particle moulded body exhibits excellent solvent resistance, and has a surface exhibiting excellent adhesive properties with respect to thermosetting resins. Furthermore, the foam-particle moulded body is capable of providing a composite stacked body which includes a thermosetting resin, and with which excellent productivity is exhibited.
