摘　　要：研究偶联剂Si69用量对多相炭黑G10填充半钢轮胎胎面胶性能的影响,并与炭黑及炭黑/白炭黑并用填充胎面胶性能进行对比。结果表明:与炭黑填充胶料相比,炭黑/白炭黑并用填充胶料的门尼粘度较大,t_(90)延长,t_(10)缩短;与炭黑/白炭黑并用填充胶料相比,多相炭黑G10填充胶料的门尼粘度明显减小,t_(90)缩短,混炼胶的Payne效应明显减弱,硫化胶的拉伸强度增大,阿克隆磨耗量和DIN磨耗量减小,压缩生热明显降低,混炼胶中炭黑分散性明显改善;随着多相炭黑G10填充胶料中偶联剂Si69用量的增大,胶料硫化特性和物理性能变化不大,损耗因子减小,其中偶联剂Si69用量为白炭黑用量8%的胶料生热较低,多相炭黑G10分散效果较好。The effect of the amount of coupling agent Si69 on the properties of the tread compound of steel-belted tire filled with multiphase carbon black G10 was studied,and the properties of the above tread compound were compared with that of the tread compound filled with carbon black and carbon black/silica.The results showed that compared with carbon black filled compound,the carbon black/silica co-filled compound had a larger Mooney viscosity,longer t90 and shorter t_(10).Compared with carbon black/silica cofilled compound,the Mooney viscosity of multiphase carbon black G10 filled compound was significantly reduced,t_(90) was shortened,the Payne effect of the compound was significantly weakened,the tensile strength of the vulcanizate was increased,the Akron abrasion and DIN abrasion were reduced,the compression heat build-up was significantly reduced,and the dispersion of carbon black in the compound was significantly improved.With the increase of the amount of coupling agent Si69 in the multiphase carbon black G10 filled compound,the vulcanization characteristics and physical properties of the compound changed little,and the loss factor decreased.The compound with the amount of coupling agent Si69 being 8%of the amount of silica had lower heat build-up and better dispersion of the multiphase carbon black G10 in the matrix.
