Abstract

ABSTRACT Ethylene vinyl acetate (EVA)/thermoplastic polyurethane (TPU) blend at various blend ratios has been modified via reactive processing with 4,4′-methylene diphenyl diisocyanate (MDI). Modification of the blends with even small amount of MDI shows significant improvement in physico-mechanical properties for EVA/TPU 50/50 and 30/70 blends, and it is also supported by the superior melt rheological behavior and dramatic improvement in oil resistance property. After the treatment of electron beam (dose range: 50–150 kGy), radiation crosslinked EVA/TPU (30:70) blend reveals further improvement in various properties. This particular material can find potential application as cable sheathing component. GRAPHICAL ABSTRACT
探讨亚甲基二苯基二异氰酸酯作为改性剂对醋酸乙烯/热塑性聚氨酯共混物的影响
摘要采用4,4′-亚甲基二苯基二异氰酸酯(MDI)对不同配比的乙烯乙酸乙烯酯(EVA)/热塑性聚氨酯(TPU)共混物进行反应改性。即使加入少量MDI,也能显著改善EVA/TPU 50/50和30/70共混物的物理力学性能,并得到优异的熔体流变性能和耐油性能的显著改善。经电子束(剂量范围:50 - 150kgy)处理后,辐射交联EVA/TPU(30:70)共混物各项性能进一步改善。这种特殊的材料可以找到潜在的应用作为电缆的护套组件。图形抽象
