【Frontiers in HaiChuan Chemical Technology】The modified bio-based silica developed independently by the Petrochemical Research Institute has passed application tests

Thread Content

On June 4, the Petrochemical Research Institute used its independently developed in-situ green modification technology to produce modified bio-based silica, which is manufactured from rice husks and carbon dioxide. This modified bio-based silica passed all series of performance tests for tires, demonstrating excellent properties.   White carbon black is another name for nano-silica; it belongs to the category of fine chemical products and is commonly used in industries such as rubber and resins. Test data show that tires incorporating modified bio-based silica not only possess physical and mechanical properties comparable to those of tires using conventional silica, but also exhibit improved key performance indicators: rolling resistance reduced by 3.7%, fatigue temperature rise decreased by 15%, and durability enhanced by 4.5%. This indicates that the modified bio-based silica products developed by the Petrochemical Research Institute are ready for industrial-scale production and market deployment.   Through the integrated application of technologies such as the resource utilization of rice husks, the chemical conversion of carbon dioxide, and green in-situ modification, the Petrochemical Research Institute has successfully produced modified bio-based silica. This material plays a vital role in extending, enhancing, and strengthening the industrial chains of new chemical materials such as synthetic rubber and synthetic resins, providing technical support for the transformation and upgrading of the refining and chemical industry within the group company.   Currently, the R&D team at the Petrochemical Research Institute has applied a series of modified silica samples to solopolymerized styrene-butadiene rubber materials. Through multiple rounds of evaluation and process optimization, the optimal silica modification process has been determined. At the same time, the Petrochemical Research Institute supplies modified samples to the cooperating tire manufacturers for performance testing and market trials, thereby facilitating the transition of technical achievements from laboratory research to industrial application.
