摘　　要：分别掺入空壳结构的导电炭黑、乙炔炭黑和抗静电剂 (SP -8)改良软质高聚合度PVC(HPVC)的抗静电性 ,同时考察了填料 (CaCO3)用量与塑炼工艺对抗静电性能的影响。结果表明 ,当导电炭黑用量大于 5 %、SP -8用量大于 2 %时 ,可得到抗静电性良好的HPVC ,碳酸钙用量以小于 10 %为宜 ;制备时塑炼温度以 160～ 180℃、时间以 5～ 10min为宜。The antistatic effect of HPVC was modified by addition conductive carbon black of hollow construction, acetylene carbon black and antistat SP-8.The influence of addition amount of CaCO 3 and processing technique on the antistatic effect was emphatically investigated. The results showed that when the amount of conductive carbon black was above 5%,the amount of SP-8 was above 2%,the amount of CaCO 3 was below 10%,the processing temperature was 160～180℃ ,and the processing time was 5～10 minutes, the antistatic soft HPVC with good antistatic effect was gained.
