Abstract

Abstract The oxidation of natural rubber (NR) leads to a decrease in mechanical properties, even resulting in failure of NR products. Many studies focusing on this single factor have failed to fully elucidate the impact of tropical island environment on NR properties. Based on this concern, the synergistic effect of thermal oxygen and ultraviolet (UV) aging on NR was systematically studied. The results revealed that thermal oxygenation can promote UV aging, which leads to the appearance of surface cracks and deepening of color. With the extension of aging time, the mechanical properties of NR correspondingly decreased. Besides, to deeply understand the mechanism of the synergistic effect of thermal oxygen and UV aging on NR, we selected squalene to simulate and analyze the molecular structure changes in NR. Based on these results, a possible synergistic effect of thermal oxygen and UV aging mechanisms on NR could be proposed.

热氧和紫外线老化对天然橡胶的协同作用

摘要天然橡胶（NR）的氧化导致力学性能下降，甚至导致NR产品失效。许多关注这一单一因素的研究未能充分阐明热带岛屿环境对NR特性的影响。基于此，系统研究了热氧和紫外线老化对NR的协同作用。结果表明，热氧化可以促进紫外线老化，导致表面裂纹的出现和颜色的加深。随着老化时间的延长，NR的力学性能相应降低。此外，为了深入了解热氧和紫外线老化对NR协同作用的机理，我们选择角鲨烯来模拟和分析NR的分子结构变化。基于这些结果，可以提出热氧和紫外光老化机制对NR可能的协同作用。

期刊介绍： e-Polymers is a strictly peer-reviewed scientific journal. The aim of e-Polymers is to publish pure and applied polymer-science-related original research articles, reviews, and feature articles. It includes synthetic methodologies, characterization, and processing techniques for polymer materials. Reports on interdisciplinary polymer science and on applications of polymers in all areas are welcome. The present Editors-in-Chief would like to thank the authors, the reviewers, the editorial staff, the advisory board, and the supporting organization that made e-Polymers a successful and sustainable scientific journal of the polymer community. The Editors of e-Polymers feel very much engaged to provide best publishing services at the highest possible level.
