创新背景

中国是全球最大的轮胎生产和消费国，溶聚丁苯橡胶的年需求量超过20万吨，主要应用于高性能轮胎的胎面，以提供高抗湿滑性(安全性)。随着中国轮胎行业的快速增长，预计中国溶聚丁苯橡胶的需求量仍会保持年均10%的速率递增。但中国的高端溶聚丁苯橡胶严重依赖进口，几乎被国外垄断。

创新过程

2022年7月23日，由中国科学院青岛生物能源与过程研究所(山东能源研究院)和中石化巴陵石油化工有限公司联合完成的“铁系催化丁戊橡胶合成与应用关键技术”项目通过了中国石油和化学工业联合会组织的科技成果鉴定。
由中国科学院院士、中科院上海有机化学研究所所长唐勇等9位专家组成的鉴定委员会认为，该项目整体技术达到国际先进水平，应加快铁系催化丁戊橡胶合成与应用关键技术的产业化。

青岛能源所(山东能源研究院)针对中国合成橡胶严重依赖进口的问题和石化下游C4~C5烯烃的高值化转化利用迫切需求，通过设计合成新型铁系催化剂，创制了铁系丁戊橡胶新材料，开发了具有自主知识产权的催化剂技术和催化聚合技术。他们与巴陵石化合作，首次实现了铁系丁戊橡胶百吨级间歇聚合和连续聚合中试放大试验，目前正在进行3万吨/年的产业化示范研究。

此外，青岛能源所(山东能源研究院)与山东玲珑轮胎股份有限公司和山东昊华轮胎有限公司等企业合作，进行了铁系丁戊橡胶在轮胎胎面胶中替代溶聚丁苯橡胶的应用技术研究，并完成轮胎制造评测。评测结果表明，铁系丁戊橡胶可以完全替代依赖进口的溶聚丁苯橡胶，且铁系丁戊橡胶轮胎的湿地抓着指数高达1.63，达到欧盟新标签法A级(参比胎B级)。
该项目创制的铁系丁戊橡胶新材料技术与产品，有望解决中国溶聚丁苯橡胶严重依赖进口的难题。该项目已经获得发明专利授权13项，其中欧洲发明专利1项，形成了具有自主知识产权的技术成果。

The new material technology was applied to solve the import problem of SBR

On July 23, 2022, the project "Key Technologies for Synthesis and Application of ferric catalyzed butadiene rubber", jointly completed by Qingdao Institute of BioEnergy and Process, Chinese Academy of Sciences (Shandong Institute of Energy Research) and Baling Petrochemical Co., LTD of Sinopec, passed the scientific and technological achievements appraisal organized by China Petroleum and Chemical Industry Federation.
The appraisal committee, composed of 9 experts including Tang Yong, academician of Chinese Academy of Sciences and director of Shanghai Institute of Organic Chemistry of Chinese Academy of Sciences, believes that the overall technology of the project has reached the international advanced level, and the industrialization of key technologies for synthesis and application of ferric catalytic butadiene rubber should be accelerated.
According to introducing, Qingdao energy (shandong) energy research institute for China's heavily reliant on imports of synthetic rubber and petrochemical downstream C4 ~ C5 olefins high value into use of urgent need, through the design synthesis of new iron series catalyst, created the iron series butyl butyl rubber, new materials developed with independent intellectual property rights of the catalyst and catalytic polymerization technology. In cooperation with Baling Petrochemical Co., LTD., they have for the first time realized the pilot scale test of 100-ton batch polymerization and continuous polymerization of iron butadiene rubber, and are currently conducting the industrialization demonstration study of 30,000 tons/year.
In addition, Qingdao Energy Institute (Shandong Energy Research Institute) cooperated with Shandong Linglong Tire Co., LTD., Shandong Haohua Tire Co., LTD., and other enterprises to carry out research on the application technology of iron series butadiene rubber instead of SBR in tire tread rubber, and completed the tire manufacturing evaluation. The evaluation results showed that iron series butaene rubber could completely replace the imported SBR, and the wet grip index of iron series butaene rubber tire was up to 1.63, which reached the new labeling law of the European Union A (reference tire B).
The NEW MATERIAL technology AND products OF iron series BUTADIene rubber created in this project are expected to solve the problem of China's heavy dependence on imports of SBR. The project has been granted 13 invention patents, including 1 European invention patent, and has formed technical achievements with independent intellectual property rights.
