Abstract

Acrylonitrile-butadiene rubber (NBR) composites reinforced with surface-modified graphene oxide were prepared via melt compounding. Graphene oxide was functionalised using 3-aminopropyltriethoxysilane (KH550), 4,4′-diphenylmethane diisocyanate (MDI), and octadecylamine (ODA), and the effects of these modifications on curing, mechanical, swelling, and durability properties were evaluated. The modified fillers enhanced torque and reduced curing time compared to neat NBR. At 6 phr loading, tensile strength improved by 132% with GO, 139% with KHGO, 164% with MDGO, and 185% with ODGO. While elongation at break and rebound resilience decreased with filler loading, hardness, compression set, crosslinking density, swelling, and abrasion resistance increased up to 6 phr but declined at higher contents. Among the fillers, ODA-modified GO offered the best reinforcement, outperforming MDI- and KH550-modified GO as well as unmodified GO.

表面改性氧化石墨烯增强丙烯腈-丁二烯橡胶复合材料的制备及性能研究

采用熔融复合法制备了表面改性氧化石墨烯增强丁腈橡胶（NBR）复合材料。用3-氨基丙基三乙氧基硅烷（KH550）、4,4 ' -二苯基甲烷二异氰酸酯（MDI）和十八胺（ODA）对氧化石墨烯进行功能化，并评估了这些改性对固化、机械、膨胀和耐久性的影响。与纯丁腈橡胶相比，改性填料提高了扭矩，缩短了固化时间。在6phr载荷下，氧化石墨烯的抗拉强度提高了132%，KHGO提高了139%，MDGO提高了164%，ODGO提高了185%。断裂伸长率和回弹回弹率随填料含量的增加而降低，硬度、压缩固结率、交联密度、溶胀性和耐磨性随填料含量的增加而增加，但随填料含量的增加而下降。其中，oda改性氧化石墨烯的补强效果最好，优于MDI-、kh550改性氧化石墨烯以及未改性氧化石墨烯。

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.
