EXPANDABLE POLYSTYRENE WITH EXCELLENT INSULATING AND FRAME RETARDANCE BY FORMING AN INSULATING PARTICLE-CONTAINING COATING LAYER ON THE SURFACE OF A FOAM RESIN PARTICLE, AND A FOAM BODY FORMED FROM THE SAME, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: An expandable polystyrene is provided to have excellent flame retardance without applying a flame retardant, and to obtain a foam material with excellent strength by preventing separation of a coating layer.;CONSTITUTION: An expandable polystyrene consists of a foam resin particle (10); and a coating layer (20) formed on the surface of the foam resin particle. The coating layer includes a binder (22) and an insulating particle (21). The binder includes a halogen-containing resin. A manufacturing method of the foam polystyrene comprises a step of coating a coating liquid including a volatile solvent, binder, and insulating particle on the foam resin particle; and a step of drying the coated foam resin particle.;COPYRIGHT KIPO 2013
