Sustainability and enhancement of recycling differing polymer waste has become a leading driver for industries associated with this type of waste. However, polymer waste streams that have not seen as 'typical' have existed in smaller but not insignificant amounts. This study has focused on the recycling of such a waste resource that is not classified as a typical one in developed countries but appears in other locations globally where opportunities for careful waste pretreatment are hindered, therefore creating a challenge for waste handling and the application of modern techniques. Compatibilizing is a strategy employed to recycle ground tire rubber (GTR) by blending with waste high density polyethylene (w-HDPE). Such processing methods and measurement techniques have been chosen to allow easy access without extra costs. For enhanced incorporation of the filler into the matrix olefin-maleic-anhydride copolymer based additives have been synthesized and have succeeded in creating a more homogenous blend with samples having a good surface appearance and mechanical properties. Outstanding Charpy impact strength at room temperature (10.1 kJ/m) has been achieved in compatibilized 70/30 w-HDPE/GTR (containing 20% PE-contaminant), while elongation at break and tensile strength have been 10.3% and 14.9 MPa. Morphological structure of rubber resources and blends have been assessed by SEM while analytical properties and other features of experimental compatibilizing additives have been studied by e.g. FT-IR.
可持续性和增强对不同聚合物废物的回收利用已经成为与这类废物相关行业的主要驱动力。然而，一些不那么常见的聚合物废物流虽然数量较少，但也不容忽视。本研究专注于回收这种在发达国家不属于典型废物的资源，但在全球其他地方却存在，这些地方缺乏仔细的废物预处理机会，因此给废物处理和现代技术的应用带来了挑战。增容是一种通过与废高密度聚乙烯（w-HDPE）共混来回收磨碎轮胎橡胶（GTR）的策略。选择了这样的加工方法和测量技术，以便在不增加成本的情况下轻松进行。为了更有效地将填料掺入基体中，已经合成了基于烯烃-马来酸酐共聚物的添加剂，并成功地制备了具有良好表面外观和力学性能的更均匀共混物。在增容的 70/30 w-HDPE/GTR（含有 20%PE 污染物）中，在室温下（10.1 kJ/m）实现了出色的夏比冲击强度（10.1 kJ/m），而断裂伸长率和拉伸强度分别为 10.3%和 14.9 MPa。通过 SEM 评估了橡胶资源和共混物的形态结构，通过 FT-IR 等方法研究了实验增容添加剂的分析性质和其他特性。
