摘要
本文研究了用聚丁二烯（M-Talc）改性滑石粉对丁腈橡胶（NBR）的补强性能。为了实现这一目标，通过可逆加成-断裂链转移（RAFT）聚合，合成了聚甲基丙烯酸缩水甘油酯-嵌段聚丁二烯-嵌段聚甲基丙烯酸缩水甘油酯（PGMA-b-PB-b-PGMA）嵌段共聚物。然后将PGMA-b-PB-b-PGMA溶液喷洒到滑石粉（talc）上并干燥，得到改性滑石粉（M-Talc）。m -滑石粉和滑石粉随后被加入丁腈橡胶。结果表明，含m -滑石的丁腈橡胶复合材料的硫化速率明显低于未改性的滑石。此外，m -滑石粉还改善了NBR基质内的分散性。NBR/ m -滑石粉复合材料的机械性能得到显著提高，抗拉强度提高30%，撕裂强度提高17%，断裂伸长率提高757%。此外，压缩组减少了37%。
Effect of talc modified by poly (glycidyl methacrylate)- block -polybutadiene- block -poly (glycidyl methacrylate) on the properties of nitrile butadiene rubber
In this study, we investigated the reinforcement of nitrile butadiene rubber (NBR) using talcum powder modified with polybutadiene (M-Talc). To achieve this, a block copolymer of poly (glycidyl methacrylate)- block -polybutadiene- block -poly (glycidyl methacrylate) (PGMA-b-PB-b-PGMA) was synthesised via reversible addition-fragmentation chain transfer (RAFT) polymerisation. The PGMA-b-PB-b-PGMA solution was then sprayed onto talc powder (Talc) and dried, yielding the modified talc (M-Talc). Both M-Talc and Talc were subsequently incorporated into NBR. The results showed that NBR composites with M-Talc exhibited a notably slower vulcanisation rate compared to those with unmodified Talc. Additionally, M-Talc demonstrated improved dispersion within the NBR matrix. The mechanical properties of NBR/M-Talc composites were significantly enhanced, with a 30% increase in tensile strength, a 17% improvement in tear strength, and an impressive 757% boost in elongation at break. Furthermore, there was a substantial 37% reduction in the compression set.
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.
