摘　　要：以聚烯烃树脂为基体,将氢氧化铝与磷氮系阻燃剂复配使用,并对阻燃剂进行表面处理,制备了低烟无卤阻燃聚烯烃电缆料。分别考察了树脂体系、阻燃剂体系、表面处理剂对聚烯烃材料性能的影响。通过配方设计,以EVA和LLDPE混合为基体、磷氮系阻燃剂与氢氧化铝复配为阻燃剂、钛酸酯和季戊四醇为表面处理剂,得到了机械性能、阻燃性能、加工性能良好的聚烯烃电缆料,符合无卤阻燃聚烯烃电缆料的技术标准,且将其用于小线径电线时线材能通过UL标准VW-1的燃烧测试。Low smoke halogenfree-flame retardant polyolefin composites were prepared with polyolefin resin as matrix, phosphorus-nitrogen flame retardant and aluminum hydroxide as flame retardant after treatment. The influence of resin system, flame retardant system and surface treating agent on properties of polyolefin composites. Through formula de-sign, polyolefin composites with excellent mechanical properties, flame retandancy and processing property was pre-pared with EVA and LLDPE as matrix, phosphorus-nitrogen flame retardant and aluminum hydroxide as flame retard-ant ,titanate and pentaerythritol as surface treatment agent, which matched the standard of harlogen free-flame retard-ant cable materials and can be used in small diameter wire which can pass VW-1 test.
