摘要：
A series of nano SiO2 grafted with organosilane (HB-2200), nano SiO2 grafted with amino (HB-2205N), nano SiO2 grafted with double bond (HB-2205D) and nano SiO2 grafted with amino-double bond (HB-2205ND) groups were prepared through liquid phase in-situ surface modification method. The structure and properties of nano SiO2/solution polymerized styrene butadiene rubber-polybutadiene rubber (SSBR-BR) composites were characterized by TEM, SEM and rheometer. The results show that compared with the unmodified nano SiO2, the compatibility between surface functionalized nano SiO2 and rubber matrix is improved, Payne effect is reduced, the interaction between nano SiO2 is weakened, and the dispersion of nano SiO2 in SSBR-BR is improved. Compared with nano SiO2/SSBR-BR composite, the mixing torque of HB-2200/SSBR-BR composite is reduced by 35.7%, the mixing energy consumption is saved by 15%, the interfacial bond between the filler and the rubber is strengthened due to the increase in the content of bound rubber, and its tensile strength is increased by 60%. The dynamic mechanical and abrasion performance analyses show that the reactive double bond group grafted on the surface of SiO2 could improve the wet slip resistance of HB-2205D/SSBR-BR composite by 40% and reduce the rolling resistance by 43%. Nano SiO2 surface grafted with reactive double bond could reduce its rolling resistance and improve its resistance to wet slip, without sacrificing the wear resistance of HB-2205D/SSBR-BR composite. It provides the basic raw materials for the preparation of high-performance tires. © 2020, Editorial Office of Acta Materiae Compositae Sinica. All right reserved.
