【摘要】研究了不同导电炭黑、十溴联苯醚（DBDPO）/Sb₂O₃复合阻燃剂对高密度聚乙烯（HDPE）性能的影响。不同导电炭黑存在不同的逾渗阈值。HDPE/DBDPO/Sb₂O₃/导电炭黑复合材料的基体呈微观网状结构,复合材料具有良好的抗静电性能,表面电阻达2.2×10³Ω,阻燃性能、物理性能等满足MT 558.1—2005的要求。更多还原

【Abstract】 The influences of different conductive carbon blacks（CB）and composite flame retardant consisting of decabrominodiphenyl oxide and Sb₂O₃（DBDPO/Sb₂O₃）on properties of high density polyethylene（HDPE）were studied.The experiments show that different kinds of CB differ in their percolation threshold.The matrix of HDPE/DBDPO/Sb₂O₃/conductive CB composite assumes a micro-reticulate structure.The composite material possesses superior antistatic property and surface resistance of 2.2×10³Ω.Its flame retardance and physical properties satisfies the requirements stipulated in the trade standard MT 558.1—2005 of the domestic coal industry.更多还原
