Title:
発泡性スチレン系樹脂粒子、予備発泡スチレン系樹脂粒子、およびスチレン系樹脂発泡成形体
Document Type and Number:
Japanese Patent JP7425639
Kind Code:
B2
Abstract:
To provide a styrene resin foam molding which can prevent blocking in foaming and molding, exhibits good fusion property and surface property while suppressing charging property in foaming and molding, and generates less static electricity; foamable styrene resin particles and preliminary foamed styrene resin particles; and a styrene resin foam molding formed from the foamable styrene resin particles and preliminary foamed styrene resin particles.SOLUTION: Foamable styrene resin particles contain a polystyrene resin and a foaming agent. The main body of the foamable styrene resin particles containing the polystyrene resin and the foaming agent is coated with 0.001 pts.mass to 0.3 pts.mass of silicone oil, 0.001 pts.mass to 0.3 pts.mass of an antistatic agent, 0.005 pts.mass to 0.5 pts.mass of a fatty acid metal salt, and 0.01 pts.mass to 0.8 pts.mass of a fusion accelerator based on 100 pts.mass of the main body of the foamable styrene resin particles.SELECTED DRAWING: None
