Flame retardant master batch of expanded polystyrene with enhanced cell uniformity and flame-resistance and a method of the manufacturing

摘要

The present invention relates to a flame-retardant master batch and method for producing expanded polystyrene foam having improved cell uniformity and flame retardancy, and minimizes the incorporation of heterogeneous resins and components when applied to polystyrene foam using a minimum amount of polymeric material, A flame-retardant master batch for polystyrene foaming can be easily manufactured which minimizes changes in mechanical properties, minimizes defective molding upon foaming, and maximizes the content of flame retardant for ensuring high flame retardancy;
