Title:
COMPOSITE RESIN EXPANDED PARTICLE AND MOLDED BODY OF THE SAME
Document Type and Number:
Japanese Patent JP2015129315
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a composite resin expanded particle molded body excellent in rigidity, heat resistance, and restorability; and a composite resin expanded particle capable of producing the molded body.SOLUTION: There is provided a composite resin expanded particle formed of a styrenic resin and a propylene resin. A propylene resin component in the composite resin expanded particle is 40 mass% or less with respect to 100 mass% of the total of the styrenic resin and the propylene resin (excluding 10 mass% or less). In a photograph obtained by using a transmission electron microscope of a cross section of an air bubble film 1 constituting the composite resin expanded particle, a dispersed phase 3 formed of the styrenic resin is dispersed in a continuous phase 2 formed of the propylene resin. A major axis of the dispersed phase 3 is 0.01-1 μm, and a ratio (major axis/minor axis) between the major axis and the minor axis of the dispersed phase 3 is 1-10.
