摘　　要：采用煅烧高岭土部分替代Sb_(2)O_(3)制备LDPE阻燃电缆护套材料,考察煅烧高岭土与卤锑阻燃剂对LDPE的协效阻燃作用,结果表明:煅烧高岭土部分替代Sb_(2)O_(3)对LDPE阻燃材料维卡软化点温度的影响不大;用20%(质量分数)煅烧高岭土替代氧化锑时,LDPE阻燃材料的起始分解温度提高,点燃自熄时间较短,具有较佳的耐热性,能够与卤锑阻燃剂起到阻燃协效作用,并能降低材料成本。This article investigates the synergistic flame retardant effect of calcined kaolin and antimony halide flame retardant on LDPE by partially replacing Sb_(2)O_(3)to prepare LDPE flame-retardant cable sheath material.The results indicate that partially replacing Sb_(2)O_(3)with calcined kaolin has little effect on the Vicat softening point temperature of LDPE flame retardant materials;When using 20%(mass fraction)calcined kaolin instead of antimony oxide,the initial decomposition temperature of LDPE flame retardant material increases,the self extinguishing time is shorter,and it has better heat resistance;It can have a synergistic effect with halogenated antimony flame retardants and reduce material costs.
