生物基衣康酸酯橡胶的设计开发与工业应用

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.
