摘要
探讨了炭黑和抗静电剂改性硅油分别使用与协同使用对聚甲醛(POM)导电性能和力学性能的影响,同时研究了增韧剂聚氨酯弹性体(TPU)对POM导电性能和力学性能的影响。结果表明:炭黑和改性硅油配合使用,可使POM的表面电阻率达到102Ω,而其力学性能也比单独使用炭黑有所改善。增韧剂TPU进一步提高了导电POM的冲击强度,但使导电POM的表面电阻率增加到106Ω。
The effects of carbon black, modified silicon oil and TPU on conductive and mechanical properties of POM were discussed. The results show that： after adding the compound of carbon black and modified silicon oil, the surface resistivity of POM decreases to 102~, the mechanical property of POM is improved than that modified by carbon black only; the addition of TPU further improves the impact strength of POM, but increases the surface resistivity of POM to 10^6Ω.
