Nano-silica anti-wear agent and its application effect
Nano-scale inorganic particles, because of their easy agglomeration to form agglomerates, and the coating base
1 a wooden substrate; 2 a wear-resistant agent particles;
3-The adhesion of the paint is very poor, use a conventional film; 4-the surface of the coating film; 5-the pressure roller

The paint production method is difficult to disperse the particles in the base material at the nanometer level, and it is difficult to obtain a transparent coating that does not affect the gloss. Therefore, the surface of the inorganic nanoparticles must be modified to be used as a wear-resistant agent in the paint. At present, most researches on nano-scale inorganic non-metallic materials are nano-scale micronized amide wax oxides such as titanium, aluminum, silicon, zirconium, and nano-scale porcelain clay and clay.

The most reported is nano silica. This article also uses it as an example to introduce the acquisition and application examples of nano-scale silica wear-resistant agents, and illustrate the application potential of emerging nano-materials and technologies in improving the wear resistance of coatings.

Nano-scale silica particles suitable for industrial use are prepared by flame hydrolysis (also known as high temperature hydrolysis) using silicon tetrachloride, so it is called fumed silica (also known as fumed silica) . It is composed of highly dispersible amorphous silica aggregates, but forms numerous agglomerates during high-temperature hydrolysis. The dispersion process of these agglomerate coatings is difficult to completely redisperse into the original initial particles. The aggregate composition is almost spherical, the original particle size is 7-40nm, the surface area is large, 50-500m²/g, and the surface is covered by silanol groups (Si-OH).
