Research progress in surface modification technology of inorganic
fillers for rubber composite materials

Abstract: Rubber, as an important raw material for tires, its application occasions determine that rubber
composite materials must have good mechanical properties. The use of inorganic fillers as reinforcing materials
to improve mechanical properties has become a development trend in recent years. The current research
hotspot in the field of rubber composite materials is the combination and use of various fillers. However, most
inorganic fillers have strong self polymerization or poor dispersibility due to their high polarity, making them less
compatible with rubber substrates. The surface modification of inorganic fillers through coupling agents can
promote their uniform dispersion in the rubber matrix, thereby endowing tire rubber materials with excellent
mechanical and dynamic mechanical properties. By reviewing relevant literature in the past decade, classify
and extract technical details of interdisciplinary research on surface modification of inorganic fillers. Conduct
a horizontal comparison of the research results of surface modification technologies for different material
systems, summarize the advantages and disadvantages, and conduct in-depth analysis. Finally, through cross
comparison, summarize the current nano level inorganic filler surface modification technologies, solve the
problems in research, and discuss solutions and future research directions.
