| 摘 要： | 在低密度聚乙烯(PE)中添加了纳米氢氧化镁(Mg(OH2))和磷酸三苯酯(TPP)组成的协同阻燃剂,采用共混挤出的方法制备了纳米Mg(OH2)/PE阻燃光缆护套料.对制得的样品进行了氧指数(OI)、示差扫描量热(DSC)法和力学性能的测试,实验结果表明,样品的OI大幅度提高,力学性能和玻璃化温度均满足阻燃光缆护套的要求.

| Abstract: | A complex flame retardant composed of nano-Mg(OH)2 and triphenyl phosphate(TPP) is added into low density PE by means of co-blending extrusion.And a nano-Mg(OH2)/PE flame retardant optical cable sheath is prepared.Oxygen index(OI),differential scanning calorimetry(DSC) and mechanical properties are used to evaluate the properties of the samples.It is proved that the OI of the samples are largely increased,both the mechanical properties and the vitrification temperature meet the requirements of flame retarda... |
