采用无卤膨胀阻燃剂(IFR)和导电炭黑(CB)对聚丙烯(PP)进行阻燃抗静电改性,制备得到了无卤阻燃抗静电聚丙烯复合材料,研究了无卤膨胀阻燃剂与导电炭黑之间的相互作用关系.结果表明, IFR 能有效提高 PP 的阻燃性能,但会影响 CB 粒子之间的相互接触,降低其导电效率；CB 能有效提高 PP的抗静电性能,改善其阻燃性能,但会降低 IFR 在 PP中的阻燃效果；CB 能提高 PP 在低温区的热稳定性,但 CB 具有高热传导性,会产生“灯芯效应”,加快 PP的分解.当 CB 含量为6份,IFR 含量为30份时,无卤阻燃抗静电聚丙烯复合材料的 LOI 为28％,表面电阻率为8．70×105Ω,拉伸强度为27．1 MPa.
In this paper,halogen-free intumescent flame retardant (IFR)and carbon black (CB)were used to prepare flame retarded and antistatic polypropylene composites.The interaction between antistatic agent and flame retardant of the flame retarded and antistatic polypropylene composites was investigated.The results indi-cated that,IFR effectively improved the flame retardancy of polypropylene,but hindered the contact between the CB particles.CB effectively improved the antistatic property and flame retardancy of polypropylene,and de-creased the flame retardancy of IFR.The high thermal conductivity of CB caused a “wicking effect”,which ac-celerated the decomposition of PP.With 6 phr CB and 30 phr IFR,the flame retarded and antistatic polypropyl-ene composites reached a LOI value of 28%,a surface resistivity of 8.70 × 10 5 Ω and tensile strength of 27.1 MPa.
