FLAME RETARDING THERMOPLASTIC ALLOY AND ITS PREPARATION METHOD

摘要

A flame retarding thermoplastic alloy and its preparation method are provided. The alloy comprises the following components with the following parts by weight: ABS resin 5-94, polyester or copolyester or the mixture of them 3-94, brominated flame retardant 1-50, flame retardant auxiliary 1-10, chloropolyethylene (CPE) 0.001-30, anti-dripping agent 0.001-2 and processing aid 0.1-6. The preparation method includes the following steps: premixing all of the components through the high speed mixer, adding into the twin-screw extruder, plastifying, mixing and extruding under 150-250°C, cooling and granulating, then obtaining the flame retarding alloy.
