三方跨界联合，计划开展木质素轮胎应用研发

Core Insights - The collaboration between South China University of Technology and Shandong Huasheng Rubber Co., Ltd. focuses on the industrial application of lignin in green tire production, showcasing a successful model of industry-academia-research cooperation [1][6] Group 1: Lignin Utilization - Lignin, a byproduct of the paper industry, can achieve high-value utilization in the rubber tire sector, addressing long-standing issues of "easy agglomeration and difficult dispersion" in rubber applications [3][8] - The research team has developed a multi-level nano-micro phase separation structure and dynamic energy sacrifice bonds, significantly improving the compatibility of lignin with rubber [3][8] - The application of lignin can reduce tire rolling resistance by 5-10% and enhance aging resistance by over 20%, while its natural UV resistance helps mitigate performance degradation during use [3][8] Group 2: Cost Efficiency and Economic Impact - Lignin's cost is only 30-50% of traditional reinforcing agents like silica, providing a buffer for tire companies against raw material price fluctuations [3][8] - The collaboration also explores the "lignin + silica" pre-dispersion technology, which improves processing performance and balances the "magic triangle" of rolling resistance, wet grip, and wear resistance in tire formulations [10] Group 3: Circular Economy Initiatives - Huatai Paper Industry is implementing a "waste-to-resource" practice by extracting high-purity lignin from paper black liquor, with a project to produce 50,000 tons of lignin annually using advanced membrane separation technology, reducing costs by 15-20% [10] - The project aims to create a circular economy loop from "green electricity - pulp - lignin - rubber," contributing to environmental sustainability [10] - Current advancements in the application of lignin in tire formulations have shown progress in sidewall and inner liner compounds, although challenges remain for large-scale replacement in tread compounds [10]
