摘　　要：采用复合阻燃填料氢氧化铝和十溴联苯醚、疏水性气相白炭黑,制备了长效防污闪涂料,考察了改性氢氧化铝与十溴联苯醚复合阻燃材料对涂料阻燃效果、力学性能和电性能的影响,以及气相白炭黑对涂料性能的影响。结果表明,氢氧化铝/十溴联苯醚混合用量为40∶5(相对于每一百份硅橡胶),气相白炭黑用量为12,涂料具有最佳的性能,能够满足《国家电网公司跨区电网输变电设备外绝缘用防污闪涂料使用指导原则(试行)》(以下简称《指导原则》)的要求。A long-acting anti-pollution flashover coating(PRTV) was prepared by compound flame-retardant fillers,aluminum hydroxide[Al(OH)3] and decabromodiphenyl ether(Deca-BDE) in which fumed silica act as reinforcing fillers.The influence of the proportion of ATH to Deca-BDE on the flame retardant effect,mechanical properties and electric properties was studied.The effect of gas hydrophobic silica dosage on the performance of the paints was also investigated.It indicates that the properties of the paints are best w...
