摘要
通过双置换反应合成了一种新型加速器--半胱氨酸铈(Ce-Cys)。通过傅立叶变换红外分析、热分析、乙二胺四乙酸滴定和元素分析,确定该复合物的分子式为 Ce (Cys)3Cl3-3H2O。研究了 NR 复合物的固化特性、交联密度、机械性能和热氧化老化。研究发现,含有 Ce-Cys 的硫化胶具有较高的焦烧时间、出色的机械性能和更好的热氧化老化性能。此外,根据动力学计算得出的结论是,随着 Ce-Cys 含量的增加,交联前体的反应活性增加,而活化能降低。
Effect of cerium cysteine on the vulcanisation property and thermo-oxidative ageing of natural rubber
A novel accelerator, cerium cysteine (Ce-Cys) was synthesised by double replacement reaction. The complex was characterised by FT-IR analysis, thermal analysis, EDTA titration and elemental analysis, respectively, to determine that the molecular formula of the complex was Ce (Cys)3Cl3·3H2O. Cure characteristics, crosslink density, mechanical properties and thermo-oxidative ageing of NR compounds were investigated. The research revealed that the vulcanisates containing Ce-Cys manifested high scorch time, outstanding mechanical properties, and better thermo-oxidative ageing properties. Furthermore, based on kinetic calculations, it was concluded that as the amount of Ce-Cys increased, the reactivity of the crosslink precursor increased while the activation energy decreased.
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.
