生物基衣康酸酯橡胶的设计开发与工业应用

Design,development and industrial application of bio-based itaconate rubber

利用可再生资源开发新一代生物基橡胶材料对于实现我国合成橡胶工业可持续发展具有重要意义。多年来,北京化工大学先进弹性体材料研究中心对生物基衣康酸酯橡胶进行了系统的分子设计、应用开发与工程放大研究。实验室阶段的研究主要包括生物基单体的选择、橡胶分子链的构建及聚合体系的优化、官能化技术开发、结构/胎面指标的灵活调控。在此基础上,与山东京博中聚新材料有限公司合作,历经2 L小试—200 L中试—千吨级的生产过程,解决了衣康酸酯橡胶在工业化进程中出现的实际问题,最终建立了千吨级聚合装置以及适配的絮凝干燥线,实现了衣康酸酯橡胶的稳定生产。与山东玲珑股份有限公司合作,基于该生物基橡胶材料的特点,研发了相适配的混炼配方及生产工艺,制备了首批双B级生物基子午线轮胎。生物基衣康酸酯橡胶的生产技术成果转化可以实现生物质资源的高附加值利用,促进我国橡胶产业的绿色可持续发展。

The use of renewable resources to develop a new generation of bio-based rubber materials is of great significance for the sustainable development of synthetic rubber industry in China.Over the years,the Advanced Elastomer Materials Research Center of Beijing University of Chemical Technology has carried out systematic molecular design,application development and engineering scale-up research on bio-based itaconate rubber.The research in the laboratory stage mainly includes the selection of bio-based monomers,the construction of rubber molecular chains and the optimization of the polymerization system,the development of functionalization technology,and the flexible regulation of structure/tread indicators.On this basis,in cooperation with Shandong Chambroad Sinopoly New Material Co.,Ltd.,through the process of 2 L small test—200 L pilot test—thousand-ton production,the practical problems of the itaconate rubber in the process of industrialization were solved,and finally the thousand-ton polymerization device and the suitable flocculation drying line were established,and the stable production of the itaconate rubber was realized.In cooperation with Shandong Linglong Co.,Ltd.,based on the characteristics of the bio-based rubber material,a suitable mixing formula and production process were developed,and the first batch of double B-class bio-based radial tires were prepared.The transformation of production technology achievements of bio-based itaconate rubber can realize the high value-added utilization of biomass resources and promote the green and sustainable development of China’s rubber industry.
