摘　　要：采用湿法球磨对纳米导电炭黑粉体BP2000进行球磨分散，获得高稳定性、高固含量的炭黑浆料。将炭黑浆料添加到聚四氟乙烯PTFE乳液中形成稳定乳液。采用线棒涂布器在玻璃纤维布表面涂布成膜，于380℃烧结后得到防静电PTFE涂层。当炭黑添加量达到1．7％时涂层电阻率低于10^4Ωcm，具有优良的防静电效果。Conductive BP2000 carbon black slurry with high stability and high solid content were obtained by wet bead mill grinding. The carbon black slurry was added to PTFE emulsion and obtained stable mixture. Coating fiberglass cloth with this carbon black PTFE slurry by bar-coatering, and sintering at 380℃, reaching an antistaic PTFE coating. The electrical resistivity of the coating was lower than 106Ω cm when the carbon black content was about 1.7%.
