THERMOSETTING EXPANDABLE RESIN COMPOSITION, LAMINATED SHEET, MOLDING AND STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a thermosetting expandable resin composition which is excellent in heat stability, in which expansion ratio does not drop even when heated to a high temperature, and which is suitably used for the reinforcement of a car body and the like, and to provide a molding and a structural member using the thermosetting expandable resin composition. SOLUTION: The thermosetting expandable resin composition comprises a thermosetting resin composition and heat expansible microcapsules contained in the thermosetting resin composition. The heat expansible microcapsule is formed from an outer shell made of a polymer obtained by polymerizing monomer components including a nitrile monomer and a volatile blowing agent which is sealed within the outer shell and gasified at the softening temperature of the polymer or lower.
