摘　　要：为探讨苯乙烯—乙烯/丁烯—苯乙烯共聚物(SEBS)的可熔喷性,对4种不同型号SEBS的切片原料进行了测试分析,筛选出了适合熔喷工艺的SEBS型号,运用正交试验优化工艺参数,并分析了鼓风频率等对非织造布性能的影响。试验结果表明:在挤出频率为2 Hz,接受距离为40 cm,鼓风频率为25 Hz时,SEBS非织造布的性能最好,得到的非织造布弹性回复率达到92%以上,拉伸应变超过700%,制得的弹性熔喷非织造布性能良好。In order to investigate the melting-blowout property of styrene-ethylene/butene-styrene copolymer(SEBS),four kinds of SEBS slicing materials were tested and analyzed,and the SEBS models suitable for melting-out process were selected.Orthogonal experiment was used to optimize the process parameters,and the effects of air blast frequency on the properties of nonwovens were analyzed.The experimental results show that the performance of SEBS nonwovens is the best when the extrusion frequency iS2 Hz,the acceptance distance iS40 cm,and the hot air blast frequency iS25 Hz.The elastic recovery rate of SEBS nonwovens is above 92%,tensile strain exceedS700%,and the elastic melt spray nonwovens have good performance.
