                                 Nano silica particles used in epoxy resin, superhydrophobic coating nano silica powder

 

Characteristics of nano-silica surface is a layer of silicone and even silanol groups, these groups have a strong absorption capacity. Silanol susceptible to chemical reaction, so that the nanometer silica surface modified more easily. These special structural and physicochemical properties, the nano silica has excellent acid, alkali, high temperature and electrical insulation, absorption, dispersion, thickening, thixotropic and cut light resistance and other properties.

 

Nano sio2 nano materials as an important member of its surface with a hydroxyl group, is ultra-fine powder, particle size <100nm, usually 20-30nm, high chemical purity, good dispersion, high specific surface area. In the chemical industry, also known as silica, it is the highest yield of a nano-powder material is currently the world's large-scale industrial production. Its products are widely used in electronic packaging materials, the field of polymer composite materials, plastics, paints, rubber, paints, ceramics, adhesives, glass, steel, pharmaceutical carriers, cosmetics and antibacterial materials.

 

Nano-silica in epoxy resin applications:

1. Heat resistance: Due to a large specific surface area of nano silica particles, the interfacial adhesion effect and epoxy matrix is strong, absorb large amounts of impact energy, but also increases the rigidity of the matrix, and therefore within the scope of certain nano silica particles toughening epoxy resin, but also improve the heat resistance of materials.

2, toughening effect: due to the addition of nano silica particles, impact strength epoxy composites, tensile strength, elongation and other properties within a certain range has improved greatly, indicating that nano-silica toughening particles played a role. It highlights the nanoscale silica excellent filling properties, and the material performance has been greatly improved.
