Abstract In recent times carbon black is getting part replaced in the tire industry by silica as the major reinforcing filler for the development of “greener tires”. The green claim comes from the fact that silica reinforcement helps in further fuel saving in vehicles and reduction in CO2 emission into the environment. Making the green claim further, researchers are also looking at reinforcement fillers that are synthesized from bio-waste as raw materials. In this paper we have evaluated the effect of replacing carbon black with highly dispersible silica derived from an agro based by-product such as rice husk ash in a basic tire tread formulation of passenger car tires. Our approach has been to first develop an economical & scalable process for extracting silicate from rice husk ash in the form of sodium silicate followed by synthesizing tire grade functionalized highly dispersible silica that have greater dispersibility in the tire rubber matrix and thereby achieve similar or better physical properties for the tire rubber with potential of reduced rolling resistance of tires.

绿色二氧化硅：在轮胎胎面胶中实现改进的“纳米填料 - 弹性体”相互作用和增强的工业可扩展和可持续方法

摘要 近年来，炭黑在轮胎工业中逐渐被二氧化硅取代，作为开发“绿色轮胎”的主要补强填料。绿色声明来自于二氧化硅增强材料有助于进一步节省车辆燃料和减少二氧化碳排放到环境中的事实。进一步提出绿色主张，研究人员还在研究以生物废物为原料合成的增强填料。在本文中，我们评估了在乘用车轮胎的基本轮胎胎面配方中用源自农业副产品（如稻壳灰）的高分散性二氧化硅替代炭黑的效果。我们的方法是首先开发一种经济且
