摘要:采用模板诱导法和模压成型法制备了高分子型抗静电剂聚丙烯接枝苯乙烯磺酸共聚物-聚苯胺(PP-g
SPS-PANI)和抗静电聚丙烯(P)材料,考察了盐酸用量、过硫酸铵/苯胺(APS/AN)物质的量比、原料磺化度等因素对抗静
电剂产率和抗静电PP材料体积电阻率的影响。结果表明:抗静电PP材料的体积电阻率比PP降低了5个数量级;在一定
范围内,增加盐酸用量和APS/AN物质的量比可提高抗静电剂产率和降低抗静电PP的体积电阻率;随着原料磺化度的提
高,样品体积电阻率逐渐降低;随着样品中抗静电剂含量的提高,样品体积电阻率不断下降,但当抗静电剂质量分数超过
10%后,电阻率变化不大

Abstract: The polymer antistatic agent PP-G-SPS-PANI and antistatic PP were prepared
by template and molding method. The factors such as Hcl amount, the effects of mole ratio
of APS/AN and sulfonation degree on the yield and volume resistivity of antistatic PP were
investigated. The results show that the volume resistivity of the antistatic electricity PP re
duces to approximate 10 "compared to pure PP With the increment of the amount of HCI
and the mole ratio of APS/AN, the yield of antistatic agent improves but the volume resis
tivity of samples decreases. Meanwhile, volume resistivity reduces gradually by the enhance
ment of the sulfonation degrec. However, when the mass ratio of antistatic agent is more
than 10 %, no obvious electronic resistivity change is observed
