不同表面活性剂处理的 Sb2O3对PV C复合材料阻燃性能的影响
Effect of Sb2 O3 M odified by Various Surface Active Agents on Flame Retardant Properties of PVC Composite
摘要
Abstract
Sb2 O3 pow ders w ere prepared by high energy ball milling using polyethyleneglycol‐6000 ,so‐dium dodecyl sulfate and OP‐10 to modify the surface properties of the powder . The influence of Sb2 O3 pow ders modified by various surface active agents on flame retardant properties of PVC com‐posite materials was studied .The phase composition ,morphology and the average particle size of the powders were characterized by XRD and TEM .The particle distribution and flame retardant proper‐ties of Sb2 O3/PVC composite materials w ere studied by EDS ,limiting oxygen index instrument and vertical burning test .T he results show that nanometer Sb2 O3 has good dispersion in the PVC matrix because of the higher space steric effect of organic film on the surface of nanometer Sb2 O3 w hen poly‐ethyleneglycol‐6000 was used as the surface active agent .While the content of nanometer Sb2 O3 is 1.26% in the PVC composite material ,the oxygen index of the composite material is 27 .1% and the composite material reaches fire retardant grade .Using sodium dodecyl sulfate and OP‐10 as surface dispersants ,the surface of Sb2 O3 powders can not be coated completely .The particle size of Sb2 O3 powders are 100nm and 150nm ,respectively ,The Sb2 O3 powders have poor dispersion in the PVC matrix ,and even some agglomerating phenomena took place .T he oxygen index of Sb2 O3/PVC com‐posite materials are 24 .7% and 25 .3% ,respectively ,containing 1 .26% Sb2 O3 powders in Sb2 O3/PVC composite material .T he materials don’t achieve flame retardant level .关键词
