Synthesis & Analysis of Silica From Bio-Waste Rice Husk Ash & Its Application in Tire Tread Compounds

Abstract
Currently tyre industry uses silica as reinforcing filler by replacing carbon black for making “greener tires”. Silica reinforcement into tire makes benefits to the environment as by replacing silica it reduces rolling resistance of tires making more fuel efficient tires as well as there is decreased in CO2 emission from the vehicles. Also this silica obtained is from bio-waste such as Rice husk ash (RHA) an agricultural waste which contains silica 80-90% solving environment waste disposal problem. The sodium silicate is extracted from the Rice husk ash & matching specification with commercial standard which further used for synthesizing functionalized highly dispersible grade silica acting as a reinforcing filler in tire & rubber. In this paper we have synthesized highly dispersible silica extracted from Rice husk ash and replaced by carbon black during rubber compounding formulation of basic tire tread compounds used in passenger car tires. In tire tread combination of Amorphous precipitated silica with silane coupling agent will acts as filler which can gives 20% reduction in rolling resistance which ultimately saved the fuel consumption. Here we have evaluated our greener silica into tire tread formulation & studied the rheological, mechanical and dynamic properties of tire rubber.
