Study on Flame Retardant and Antistatic Properties of Polypropylene Composites

Polypropylene （PP） composites were prepared based on a fire retardant ANTI?660 and an antistatic agent glyceryl monoacetate （Gm）. The effects of flame retardant and antistatic agent on the flame retardant， antistatic and mechanical properties of the composites were characterized using horizontal and vertical combustion tester， oxygen index tester， surface resistance tester， universal testing machine and pendulum impact testing machine. The result indicated that with the addition of 18.0 wt% fire retardant and 2.0 wt% antistatic agent， the limiting oxygen index of the composites reached 26.0 vol%， their vertical combustion reached a V?0 classification， and their surface resistance decreased down to 1.7×10¹² Ω. There is no obvious difference in mechanical properties between the composite system with only a flame retardant and the system with both of the flame retardant and antistatic system. However， the composites with both of additives still keep high comprehensive mechanical performance.
