Anti-fouling, heat-resistant and scratch-resistant nanosilica dispersion

Nanosilica is widely used in electronics, medicine, biology, rubber, plastics, paints, coatings, ceramics and other industries. Our company has been producing silica powder with particle sizes in nanometers since the year. This process technology has been identified as the first in China and has reached the international advanced level. It has applied for a national invention patent. With the widespread application of nanomaterials, the problems of easy agglomeration and difficulty in dispersion of nanopowder materials have become increasingly prominent, and nanosilica is no exception. This not only requires special dispersion equipment and is complicated to operate, but what is obtained is only a dispersion of silica agglomerates, far from a dispersion of single nanoparticles. This is because the particles of nanosilica are extremely small, the surface atomic ratio is high, and the specific surface area is Large, the particles are easily attracted to each other through van der Waals force, hydrogen bonding and covalent bonding, forming secondary particle size and tertiary particle size, that is, agglomerates. The resultant force between the particles of these agglomerates (van der Waals force, hydrogen bonding , the sum of covalent bonds) is often above /. The shear force of general mixing equipment can only reach /, so it cannot truly deaggregate and fully disperse. Even if some agglomerates temporarily deaggregate under the action of external force, they will reunite again after the external force is removed.
In order to solve the problem of dispersion of nanomaterials, our company began research on dispersion technology in 2016, and has now successfully developed a new molecular dispersion method that can completely depolymerize nanomaterials. Using this dispersion technology, our company can evenly disperse our self-made nano-silica powder into water, butyl acetate, methyl ethyl ketone, ethylene glycol, diethylene glycol, etc. in the unit of single nanoparticles. In a variety of solvent media, the resulting dispersion has good stability. In a variety of products such as coatings, inks, paints, plastics, rubber, and other polymer materials.
