Abstract

Ground rubber from automobile tires is very difficult to recycle due to the cross-linking of the macromolecules and thus the lack of thermoplastic properties. The research consisted of assessing the processing possibility via the injection of highly filled PP/GTR compounds modified with 1.5 wt.% 2.5-dimethyl-2.5-di-(tert-butylperoxy)-hexane. GTR dosing ranged from 30 wt.% up to 90 wt.%. The evaluation of the processing properties of the obtained materials was carried out on the basis of the melt flow index test results and the signals recorded during processing by the injection molding by temperature and pressure sensors placed in the mold. The influence of the applied modifier on the changes in the mechanical properties of PP/GTR was determined with hardness, impact and static tensile tests. Moreover, thermal properties were obtained by the differential scanning calorimetry method. It has been found that it is possible to efficiently process compounds with high GTR content using injection molding. The presence of the filler allows to significantly reduce the cooling time in the injection mold and thus the time of the production cycle. It has been confirmed that 2.5-dimethyl-2.5-di-(tert-butylperoxy)-hexane modifies the rheological properties of PP and thus the PP/GTR composition. The lower viscosity of the matrix results in a more accurate bonding with the developed surface of the GTR grains, which results in better mechanical properties of the rubber-filled polypropylene.

摘要

由于高分子的交联作用，汽车轮胎的磨碎胶粉缺乏热塑性，因此很难回收利用。该研究包括评估通过注射含有1.5 wt.% 2.5-二甲基-2.5-二(叔丁基过氧)-己烷改性的高填充PP/GTR化合物的加工可能性。GTR的用量范围为30 wt.%至90 wt.%。根据熔体流动指数测试结果以及通过置于模具中的温度和压力传感器在注射成型过程中记录的信号，对所得材料的加工性能进行评估。通过硬度、冲击和静态拉伸试验确定所应用的改性剂对PP/GTR力学性能变化的影响。此外，通过差示扫描量热法获得热性能。已发现使用注射成型能够高效加工高GTR含量的化合物。填料的存在能够显著缩短注射模具中的冷却时间，从而缩短生产周期。已证实2.5-二甲基-2.5-二(叔丁基过氧)-己烷改变了PP的流变性能，进而改变了PP/GTR组合物的流变性能。基体较低的粘度导致与GTR颗粒的发达表面有更精确的结合，从而使橡胶填充聚丙烯具有更好的力学性能。
