摘要
利用十六烷基三甲基溴化铵对钠基蒙脱土进行有机改性,将得到的纳米蒙脱土(NanoMMT)添加到线性低密度聚乙烯(LLDPE)中,通过熔融纺丝制备运动草坪纤维。借助电子强力织物机、磨损试验机和极限氧指数测试仪等手段,研究了Nano-MMT对纤维的力学性能、耐磨性能和阻燃性能的影响。结果表明:Nano-MMT的加入可以提高纤维的力学性能,在Nano-MMT添加质量分数为3%时,力学性能达到最大值,拉伸强度为22.1 N,断裂伸长率达到146.7%;少量Nano-MMT的加入可以降低纤维的磨损量,在Nano-MMT添加量为3%时,纤维的磨损量从30.2mg降低到12.2 mg,比未添加Nano-MMT时的磨损量降低了59.6%;Nano-MMT的加入可以提高纤维的阻燃效果,单独加入阻燃荆的氧指数为19.3%,而加入w=3%的Nano-MMT后,氧指数能达到22.5%。
Montmorillonite was organic modified by cetyl trimethyl ammonium bromide. The linear low density polyethylene （LLDPE）/nano-montmorillonite （nano-MMT） gymnastic artificial turf fibers were prepared by melt spinning. The influences of nano-MMT on the mechanical properties, wear resistance and flame retardant properties of LLDPE fibers were determined by electric fabric strength tester, wear testing machine and limiting oxygen index tester. The results showed that the adding of nano MMT improved the properties of LLDPE fibers. When the mass fraction of nano-MMT was 3%, the properties of LLDPE fibers were the best, the tensile strength was 22. 1 N and the elongation rate was 146.7% ; the wear amount of the fiber decreased from 30. 2 mg to 12. 2 rag, decreased by 59. 6%, the oxygen index value increased from 19.3% to 22.5%.
