摘　　要：以聚乙烯(PE)电缆回收料为主要原料,制备了再生三层结构PE(3PE)防腐PE专用料,并通过万能材料试验机、熔体流动速率仪、密度天平和热变形维卡测试仪研究了其性能。结果表明:加入聚烯烃弹性体(POE)或乙烯-醋酸乙烯共聚物(EVA)均可以提升3PE防腐PE专用料的拉伸强度和断裂伸长率。当PE电缆回收料、高密度聚乙烯(HDPE)、二甲基硅油、炭黑、irganox 1010、irganox 168、POE的用量分别为70.00质量份、30.00质量份、0.50质量份、6.00质量份、0.30质量份、0.20质量份、2.00质量份时,3PE防腐PE专用料的各项性能满足GB/T 23257—2017《埋地钢质管道聚乙烯防腐层》的性能要求,测试值表现出良好的稳定性,且PE电缆回收料用量较大,具有深入研究的价值。Using polyethylene(PE)cable recycling material as the main raw material,three-layer PE(3PE)anticorrosive polyethylene special material was prepared.Its performance was studied using a universal material testing machine,melt flow rate meter,density balance and thermal deformation Vicat tester.The results show that the addition of polyolefin elastomer(POE)or ethylene-vinyl acetate copolymer(EVA)can improve the tensile strength and elongation at break of 3PE anticorrosive polyethylene special material.When the amounts of PE cable recycling material,high density polyethylene(HDPE),dimethyl silicone oil,carbon black,irganox 1010,irganox 168 and POE are 70.00,30.00,0.50,6.00,0.30,0.20 and 2.00 phr respectively,the various properties of 3PE anticorrosive polyethylene special material meet the performance requirements of GB/T 23257—2017“Polyethylene Coating for Buried Steel Pipeline”.The test values show good stability.The amount of PE cable recycling material is relatively large,which has the value of in-depth research.
