Abstract

Halloysite nanotubes (HNTs) were chemically functionalized with the vulcanization accelerator N-cyclohexyl-2-benzothiazole sulfenamide (CZ) to prepare CZ-grafted HNTs (HNTs-s-CZ), which were incorporated into acrylonitrile butadiene rubber (NBR)/styrene-butadiene rubber (SBR) blends. The chemical grafting of the accelerator at the filler–rubber interface promoted stronger filler–matrix interaction and facilitated the formation of a compact interfacial polymer network. Compared with unmodified HNTs and physically mixed CZ systems, the HNTs-s-CZ filled composites exhibited superior curing and mechanical performance. Notably, tensile strength was enhanced by 147% with HNTs and further increased to 186% with HNTs-s-CZ. While elongation at break and rebound resilience decreased with increasing nanotube content, properties such as tear strength, hardness, and abrasion resistance improved correspondingly. Overall, HNTs-s-CZ reinforced composites demonstrated significantly better performance than those containing pristine HNTs, confirming the effectiveness of the chemical grafting strategy.

n -环己基-2-苯并噻唑磺胺接枝高岭土纳米管对丁腈橡胶/SBR复合材料性能的影响

用硫化促进剂n -环己基-2-苯并噻唑磺胺（CZ）对高岭土纳米管（HNTs）进行了化学官能化，制备了CZ接枝的高岭土纳米管（HNTs-s-CZ），并将其掺入丁腈橡胶(NBR)/丁苯橡胶（SBR）共混物中。促进剂在填料-橡胶界面的化学接枝促进了填料-基质之间更强的相互作用，有利于形成致密的界面聚合物网络。与未改性的HNTs和物理混合的CZ体系相比，HNTs-s-CZ填充复合材料具有更好的固化性能和力学性能。值得注意的是，HNTs的抗拉强度提高了147%，HNTs-s- cz的抗拉强度进一步提高到186%。随着纳米管含量的增加，材料的断裂伸长率和回弹回弹性降低，撕裂强度、硬度和耐磨性等性能相应提高。总体而言，HNTs-s- cz增强复合材料的性能明显优于含有原始HNTs的复合材料，证实了化学接枝策略的有效性。

期刊介绍： The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science. The Journal of Rubber Research welcomes research on: the upstream, including crop management, crop improvement and protection, and biotechnology; the midstream, including processing and effluent management; the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory; economics, including the economics of rubber production, consumption, and market analysis. The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines. Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
