Study on Formula of New Type Flame Retardant Polyethylene
Abstract:
The Formula of flame retardant material for PE insulated cable was developed. It mainly included 42 phrs LDPE,18 phrs EVA,7phr Magnesium carbonate,32phr Aluminum hydroxide,6phr silica,6phr Zinc borate and 5phr Silicone. The mixture was extruded through mixing and samples were made. Relative experiment showed that silicone had good effect on improvement of flame retardant properties of insulating materials. Zinc borate had promoting effect of the flame retardant. Silica had barrier effect. When parts of PE was substituted by EVA, the mechanical and flame retardant properties of the materials increased.
