中文摘要: |
以废弃缓冲空气垫( LDPE/ PA6/ LLDPE) 复合薄膜为基体材料,低密度聚乙烯接枝马来酸酐( LDPE-g-MAH)为相容剂,通过混合、挤出、吹塑工艺制备了LDPE/ PA6/ LLDPE 再生共混材料,并对相容剂添加量(质量分数)分别为3%,8%,12%,16%时再生共混材料的力学性能、阻隔性能、熔体流动性能和微观形态结构进行了测试与分析。结果表明,LDPE-g-MAH 的加入明显改善了尼龙和聚乙烯共混两相的界面相容性;相容剂添加量为3% ~8%的再生共混材料的阻隔性能较好,相容剂添加量为8% ~16% 的共混合金的力学性能得到了显著提高。 |
英文摘要: |
Recycled blends were prepared by mixing, extrusion and blow molding process using recycle of the waste air bag made of LDPE/ PA6/ LLDPE as base material and LDPE-g-MAH (maleic anhydride grafted low-density polyethylene) as compatibilizer. The mechanical, barrier, melt flow properties as well as fracture surface microstructure morphology of the blends of 3%, 8%,12%, and16% (mass fraction) compatibilizer were tested and analyzed. The results showed that LDPE-g-MAH addition significantly improved Nylon and polyethylene blends interface compatibility between the two phases; the blend with addition of 3% to 8% compatibilizer has better barrier properties; the mechanical properties of the blends with addition of 8% to 16% compatibilizer has been significantly improved. |
