Modified spherical silica micropowder, due to its high sphericity and good surface fluidity, can be evenly distributed in composite materials, enhancing the filling amount while reducing the amount of resin needed, maintaining excellent fluidity. The modified treatment lowers the oil absorption value of the silica micropowder, indicating a decreased demand for the organic matrix in the composite, which aids in cost reduction and performance improvement. High sphericity not only improves the material's fluidity but also reduces the system's viscosity, enhancing processing properties, making the composite easier to process and shape. After modification, the compatibility between the spherical silica micropowder and the organic matrix is improved, as is the bonding strength, contributing to the overall performance enhancement of the composite material. The modified treatment can also impart specific functionalities to the spherical silica micropowder, such as improved wear resistance, corrosion resistance, and high-temperature resistance, to meet the demands of different fields.
