摘　　要：为了获得一种强度高、耐热性强的塑料导爆管,引入硫酸钙晶须(CSW)与沙林(Surlyn)对低密度聚乙烯(LDPE)进行双重增强改性,制备LDPE/CSW、LDPE/CSW/Surlyn,通过拉伸强度试验、断面形貌观察、TG-DSC测试,得到一种综合性能较好的LDPE改性材料(LCS-25),并拉制导爆管。性能测试结果表明:LCS-25导爆管与LDPE导爆管相比,爆速提高了8.43%,最大断裂力提高了38.56%,80℃热收缩率降低2.08倍。In order to obtain a kind of plastic nonel tube with high strength and heat resistance,LDPE was double reinforced by calcium sulfate whisker CSW and Surlyn.LDPE/CSW and LDPE/CSW/Surlyn were prepared,and a kind of LDPE modified material(LCS-25)with good comprehensive properties was obtained by tensile strength test,section morphology observation,TG-DSC test.Test results indicated that compared with LDPE nonel tube,the detonation velocity of LCS-25 is increased by 8.43%,the maximum breaking force is increased by 38.56%,and the heat shrinkage rate at 80℃is decreased by 2.08 times.
