Application of New Sustainable Silane Coupling Agent NXT Z45 in Green Tire Tread Compound
The application of the new sustainable silane coupling agent NXT Z45 in green tire tread compounds was studied,and the effect of silanization reaction time on the properties of the compound was investigated and compared with coupling agent Si69.The results showed that,when the coupling agent Si69 is replaced by a reduced amount,the silane coupling agent NXT Z45 could improve the dispersibility of silica in the rubber matrix,enhance the processing performance and storage stability of the compound,reduce the rolling resistance of the vulcanizate,improve the wet skid resistance and maintain equivalent basic physical properties.In addition,ensuring sufficient silanization reaction time could improve the wear resistance of the vulcanizate.
