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几LDPE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。
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 marphology 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.
