Features
Due to the small size and high surface activity of nanoparticles, they are easy to agglomerate and lose their due role in strengthening and toughening the polymer, so the nanoparticles should be fully dispersed when preparing nanoparticle filled composites. Milling, high-speed shearing, ball milling, sanding, ultrasonic and other treatments will help disperse the nanoparticles in the resin.
Because the surface energy of nanoparticles is high, the adsorption effect is strong, easy to gather, and it is difficult to disperse uniformly and stably, so we use grinding, high-speed shear, ball milling, sanding, ultrasonic and other methods and coupling agent treatment methods to promote the uniform dispersion of nano silica in epoxy resin.
According to the single molecular layer theory of coupling agent, the particle size decreases, the amount of coupling agent increases, and the mass ratio of silane coupling agent to nano-silica is 5/100.

Applications
The application of nano silica in epoxy resin:
1, heat resistance: due to the large specific surface area of nano-silica particles, the interface bonding with the epoxy matrix is strong, absorbs a lot of impact energy, but also increases the rigidity of the matrix, so nano-silica particles in a certain range to strengthen and toughen the epoxy resin, but also improve the heat resistance of the material.
2, strengthening and toughening effect: due to the addition of nano silica particles, the impact strength, tensile strength, elongation at break and other properties of epoxy resin composites have been greatly improved in a certain range, which indicates that nano silica particles have played a role in strengthening and toughening. It highlights the filling characteristics of nanoscale silica and greatly improves the properties of the material.
Storage Conditions
Nano silica should be stored in a dry, airtight environment, not exposed to volatile substances.
