Abstract

The aim of the study is the development of two-layer materials based on ultra-high-molecular-weight polyethylene (UHMWPE) and isoprene rubber (IR) depending on the vulcanization accelerators (2-mercaptobenzothiazole (MBT), diphenylguanidine (DPG), and tetramethylthiuram disulfide (TMTD)). The article presents the study of the influence of these accelerators on the properties and structure of UHMWPE. It is shown that the use of accelerators to modify UHMWPE leads to an increase in tensile strength of 28-53%, a relative elongation at fracture of 7-23%, and wear resistance of three times compared to the original UHMWPE. It has been determined that the introduction of selected vulcanization accelerators into UHMWPE leads to an increase in adhesion between the polymer and rubber. The study of the interfacial boundary of a two-layer material with scanning electron microscopy (SEM) and infrared spectroscopy (FTIR) showed that the structure is characterized by the presence of UHMWPE fibrils localized in the rubber material due to mechanical adhesion.

摘要

本研究的目的是基于超高分子量聚乙烯（UHMWPE）和异戊二烯橡胶（IR），根据硫化促进剂（2-巯基苯并噻唑（MBT）、二苯胍（DPG）和二硫化四甲基秋兰姆（TMTD））开发两层材料。本文介绍了这些促进剂对UHMWPE性能和结构的影响。结果表明，使用促进剂对UHMWPE进行改性后，其拉伸强度提高了28-53%，断裂相对伸长率提高了7-23%，耐磨性是原始UHMWPE的三倍。已确定在UHMWPE中引入选定的硫化促进剂会导致聚合物与橡胶之间的附着力增加。通过扫描电子显微镜（SEM）和红外光谱（FTIR）对两层材料的界面边界进行研究表明，该结构的特征是由于机械粘附作用，UHMWPE原纤维存在于橡胶材料中。
