Abstract

The itaconate rubber, as a novel bio-based rubber, holds significance for the sustainable development of synthetic rubber. Guided by the development of tread materials with high bio-based content and high abrasion resistance, a study was conducted on the formulation of composites based on poly (dibutyl itaconate-co-butadiene) (PDBIB). In this paper, based on bio-based itaconate rubber, bio-based silica and lignin/zinc oxide (lignin/ZnO) were used to obtain rubber composites with a bio-based content of 72%. The tensile strength of itaconate rubber composite reinforced by bio-based silica can reach 18 MPa; lignin/ZnO has a good effect on the aging performance of rubber composites, which results the aging factor being increased from 0.49 to 0.62. In order to further improve its abrasion resistance as a tire, we introduced carbon nanotubes to increase its abrasion resistance by 7%, and analyzed the mechanism for the improvement of its abrasion resistance. In summary, this research provides a comprehensive analysis into the use of itaconate rubber in tread application, resulting in a high bio-based and abrasion-resistant tread rubber composite. This work offers strategic insights for the development of bio-based green tires for New Energy Vehicles.

以衣康酸酯橡胶为基材的高生物基耐磨胎面橡胶的制备及性能研究

衣康酸酯橡胶作为一种新型的生物基橡胶，对合成橡胶的可持续发展具有重要意义。以高生物基含量、高耐磨性胎面材料的发展为指导，研究了以聚乙酸二丁酯-共丁二烯（PDBIB）为基的复合材料的配方。本文以生物基衣康酸橡胶为基材，采用生物基二氧化硅和木质素/氧化锌（木质素/氧化锌）制备了生物基含量为72%的橡胶复合材料。生物基二氧化硅增强衣康酸酯橡胶复合材料的抗拉强度可达18 MPa；木质素/ZnO对橡胶复合材料的老化性能有较好的影响，使其老化系数由0.49提高到0.62。为了进一步提高其作为轮胎的耐磨性，我们引入碳纳米管使其耐磨性提高7%，并分析了其耐磨性提高的机理。综上所述，本研究对衣康酸酯橡胶在胎面应用中的应用进行了全面的分析，从而得到了一种高生物基和耐磨胎面橡胶复合材料。这项工作为新能源汽车生物基绿色轮胎的发展提供了战略见解。
