The world's first bio-based degradable rubber industrialization project was signed
2023/7/27
The technology of this project is researched and developed by Beijing University of Chemical Technology, invested and developed by Jiangsu Henghui Security Co., Ltd., Beijing University of Chemical Technology, South China University of Technology and Tongcheng New Materials Group Co., Ltd. technology shares, with a total investment of 1 billion yuan, will land in Rudong County Yangkou Port Economic Development Zone.
"We should have materials created by the Chinese themselves, which can be used and contribute to the development of human society." Zhang Liqun, an academician of the Chinese Academy of Engineering, the first initiator of bio-based degradable polyester rubber, said that bio-based degradable polyester rubber Not only has independent intellectual property rights, but also fills the gap in the field of independent synthetic rubber varieties in my country. In the next step, the team will continue to explore new technologies and new applications of synthetic rubber through the development model of in-depth integration of industry, education and research in which enterprises propose questions, universities and enterprises jointly answer the questions, and finally the enterprises review the papers.
Wang Chao, the technical director of the project, a professor at the School of Materials Science and Engineering, Beijing University of Chemical Technology, introduced the overall situation of the project and said that the technology involved in the project has mature industrialization conditions. The research work on bio-based polyester elastomers began in 2003, and it has been more than 20 years. The research team has carried out a lot of research on molecular structure design, polymerization process and equipment, high-efficiency catalysts, composite material composition control and interface interaction, etc. It broke through a series of technical bottlenecks of new polyester rubber from the laboratory stage to the small test and pilot test, solved the processing problem and service performance improvement problem, and finally prepared a green, low-carbon, non-toxic and harmless bio-based rubber with excellent performance. Degradable polyester rubber and its downstream products. Under composting conditions, more than 70% of the rubber can be completely converted 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, the China Petroleum and Chemical Industry Federation appraised that the technology is original in terms of molecular structure and has reached the international leading level as a whole. At the same time, the technology has successfully passed the 100-ton small test and the 1,000-ton pilot test, and successfully developed new degradable tires, degradable shoes, degradable chewing gum, degradable plastic tougheners, and fully degradable masks. Degradable products are expected to fundamentally solve the wear debris pollution caused by tires and other products, and alleviate the environmental pressure of non-recyclable and non-degradable rubber products.
Lei Changchun, secretary-general and vice-chairman of the China Rubber Industry Association, believes that under the background of "double carbon", the industrialization of bio-based degradable polyester rubber has good application prospects and has an important demonstration and leading role in the development of the rubber industry. .
Wang Xianhua, chairman of Henghui Security, said that the construction of bio-based degradable rubber projects can not only meet the company's demand for high-end core raw materials, but also open up a new growth curve that is conducive to the company's development. In the future, it is hoped that this project can be built into a "lighthouse" project for the rubber industry to realize the greening, industrialization, and coordinated advancement of the entire life cycle of the rubber industry.
It is understood that the bio-based degradable polyester rubber project was proposed and developed for the first time in my country. The strong support of the company and so on.
JIN DUN CHEMICAL has built a special (meth) acrylic monomer manufacturing base in ZHEJIANG province. This makes sure the stable supply of HEMA, HPMA, HEA, HPA, GMA with high level quality. Our special acrylate monomers are widely used for thermosetting acrylic resins, crosslinkable emulsion polymers, acrylate anaerobic adhesive, two-component acrylate adhesive, solvent acrylate adhesive, emulsion acrylate adhesive, paper finishing agent and painting acrylic resins in adhesive.We have also developed the new and special (meth) acrylic monomers and derivatives. Such as the fluorinated acrylate monomers, It can be widely used in coating leveling agent, paints, inks, photosensitive resins, optical materials, fiber treatment, modifier for plastic or rubber field. We are aiming to be the top supplier in the field of special acrylate monomers, to share our rich experience with better quality products and professional service.
