Application of New Silane Coupling Agent IMLV in Silica Filled Tread Compound
The application of the new silane coupling agent IMLV in the silica filled tread compound was studied,and the total amount of non methane total hydrocarbons(NMHC)generated during the mixing process was monitored using a gas chromatography analyzer.The results showed that by using an equal amount of silane coupling agent IMLV instead of silane coupling agent Si69 in the tread compound,the Mooney viscosity of the compound was decreased,the scorching time was prolonged,the vulcanization rate was increased,and the Payne effect was strengthened.The modulus at 300％of the vulcanizate was decreased,the elongation at break,the DIN wear and loss factor were increased,the hardness,tensile strength and rebound value were comparable,and the NMHC total amount generated during the mixing process was significantly reduced.
