[Ten years of development in chemical technology] 184-2023 Signing of the world’s first 10,000-ton biodegradable polyester rubber project
Thread Content
Chemical technology has developed greatly in the past ten years, praising China's prosperity and strength. It is more lively and exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss. Pay attention to fire prevention. On July 20, the signing ceremony of the world's first 10,000-ton biodegradable polyester rubber industrialization project was held in Rudong County, Nantong City, Jiangsu Province. Relevant persons in charge of Jiangsu Henghui Security Co., Ltd., Beijing University of Chemical Technology, South China University of Technology, Tongcheng New Materials Group Co., Ltd., and Yangkou Port Economic Development Zone jointly signed the contract. On the same day, the unveiling and industrialization project signing ceremony of the Jiangsu Green Elastomer Material Industry Academician Collaborative Innovation Center (Academic Innovation Center) was held in Rudong. The project will be launched in Yangkou Port Economic Development Zone, Nantong, Jiangsu, with a total investment of 1 billion yuan. After completion, it can achieve an annual output of 110,000 tons of bio-based degradable polyester rubber, and the first phase will build a production line with an annual output of 10,000 tons. Jointly funded by Henghui Security, Rudong Yineng, and Shenzhen Lixin, the new company was established using the scientific and technological achievements and technologies of Beijing Beihua University Investment Company, South China University of Technology Asset Management Co., Ltd., Tongcheng New Materials, and the scientific research team as shares. According to Wang Chao, a professor at the School of Materials Science and Engineering at Beijing University of Chemical Technology and the technical leader of the project,: Research work related to bio-based polyester rubber began in 2003. His research team broke through a series of technical bottlenecks in the process of new polyester rubber from the laboratory stage to small and pilot tests, solved processing problems and service performance improvement issues, and finally prepared bio-based degradable polyester rubber and its downstream products that are green, low-carbon, non-toxic and harmless and have excellent performance. Under composting conditions, more than 70% of the rubber can be completely transformed into water and carbon dioxide within 130 days, and the remaining part has no risk of environmental pollution. It is a new type of environmentally friendly rubber material. In 2021, it was identified by the China Petroleum and Chemical Industry Federation that this technology is original in terms of molecular structure and has overall reached the international leading level. At present, the research team has successfully developed new degradable products such as degradable tires, degradable shoes, degradable chewing gum, degradable plastic tougheners, and fully degradable masks, which are expected to fundamentally solve the wear debris pollution generated by tires and other products and alleviate the environmental pressure problem of difficult-to-recycle, non-degradable rubber products.

In April 2021, organized by China Petroleum and Chemical Industry Federation, the Advanced Elastomer Materials Research Center of Beijing University of Chemical Technology (affiliated to the School of Materials Science and Engineering and Organic-Inorganic Composite Materials* * The scientific and technological achievements of "Bio-based degradable polyester rubber materials" completed mainly by the Key Laboratory of Science and Technology were appraised and evaluated. This biodegradable polyester rubber is my country's original synthetic rubber variety. The Advanced Elastomer Materials Research Center of Beijing University of Chemical Technology has carried out related work since 2003. * * Key projects of the Natural Science Foundation, Key R&D Plan of the Ministry of Science and Technology during the 13th Five-Year Plan, * * With funding from the Basic Science Center Project of the Natural Science Foundation of China and strong support from well-known domestic and foreign companies such as Tongcheng New Materials Group Co., Ltd., after eighteen years of scientific research, a non-crystalline, cross-linkable bio-based polyester rubber material was synthesized for the first time using molecular structure design. From the laboratory stage to small tests and then to pilot tests, through a large number of experiments, the problem of continuous production process of high molecular weight multi-component copolyester rubber was finally broken through, and a thousand-ton continuous pilot test was completed. Beijing Xinyou Engineering Technology Co., Ltd. and Sinopec Shanghai Petrochemical Polyester Department provided strong support during the pilot test stage.
