Abstract

ABSTRACT Effect of concurrent inclusion of two type fillers, i.e. OMMT and NOR, on rheological, morphological, thermal and flame retardant properties of the PP/PEVA blends has been studied. The co-continuous morphology became finer with OMMT, NOR and OMMT/NOR inclusion. The result of rheological study revealed that the polymer blend and the NOR loaded composite possess liquid-like, whereas the OMMT composites represent solid-like behavior. Moreover, in OMMT loaded composite, a G’ and G” crossover in low frequency range appeared due to formation of network-like structure between OMMT layers. Thermogravimetric analysis corroborated the concurrent inclusion of OMMT and NOR in nitrogen atmosphere decreases To by 2%, increases the T max1 by 0.9% and increases T max2 by 2% comparing the blended composition. The results of microscale combustion calorimetry showed that concurrent incorporation of OMMT and NOR decreases the peak heat release rate and total heat release by 32% and 4% comparing the polymer blend, respectively.

有机粘土和硝基醚对共连续PP/EVA共混物流变学、热性能和阻燃性能的影响

研究了两种类型的填料(OMMT和NOR)同时包合对PP/PEVA共混物流变、形态、热性能和阻燃性能的影响。随着OMMT、NOR和OMMT/NOR的加入，共连续形貌变得更加精细。流变学研究结果表明，聚合物共混物和负载not的复合材料具有类液体行为，而负载OMMT的复合材料具有类固体行为。此外，在负载OMMT的复合材料中，由于OMMT层之间形成网状结构，在低频范围内出现了G’和G’交叉。热重分析证实，与混合组分相比，OMMT和NOR在氮气气氛中同时夹杂使To降低2%，使tmax1升高0.9%，使tmax2升高2%。微尺度燃烧量热法结果表明，与聚合物共混物相比，同时掺入OMMT和NOR的峰值放热率和总放热率分别降低了32%和4%。

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
