Title:
EXPANDABLE STYRENE RESIN PARTICLE, PRELIMINARY EXPANDABLE STYRENE RESIN PARTICLE, STYRENIC RESIN EXPANDABLE MOLDING, AND, MANUFACTURING METHOD OF EXPANDABLE STYRENIC RESIN PARTICLE
Document Type and Number:
Japanese Patent JP2022153315
Kind Code:
A
Abstract:
To provide expandable styrenic resin particles high in environmental contribution, capable of developing excellent spheroidizing and excellent in moldability and its manufacturing method, a pre-expanded styrenic resin particles obtained from such expandable styrenic resin particles, and a styrenic resin foam molding molded from such expandable styrenic resin particles or pre-expanded styrenic resin particles.SOLUTION: Expandable styrenic resin particles are expandable styrenic resin particles obtained by injecting a volatile blowing agent into the styrenic resin particles (A) obtained by adding a styrene-based monomer to the recycled styrenic resin particles and polymerizing them. wherein a content of the regenerated styrene resin particles with respect to a total amount of the regenerated styrene resin particles and the styrene monomer is 10 mass% to 90 mass%, an injection temperature when press fitting the volatile foaming agent is 40°C to 89°C.SELECTED DRAWING: None
