Nano Silica/SiO2 powder used in the field of paint

1.Nano-silica has a three-dimensional network structure, and large surface area, showing great activity, can form a network in the dry coating structure, not only increasing the strength of paint and finish, but also improve the suspension of the pigment.It can keep the color of paint long-term does not fade.

2.In the building interior and exterior paint, if the addition of nano-silica, can significantly improve the coating of the opening effect, the paint is not layered, with thixotropy, anti-sagging, good performance, especially anti-pollution performance greatly improved, with excellent self-cleaning ability and adhesion.

3.Nano-SiO2 can also be used with organic pigments, can be photochromic paint. Researchers used a sol-gel method to synthesize a fully transparent, temperature-resistant coating containing nano-silica. Some synthesized a very thick coating containing nano-SiO2, which can resist high temperature, no cracks at 500 ℃. Other synthetic P MMA-SiO2 nano-coating, and it significantly enhanced the flexibility and strength of the coating.

4.Nano-silica shows the special optical properties compared with conventional SiO2. Nano silica has a strong UV absorption, infrared reflection characteristics. The UV-visible spectrophotometer showed that it had a UV absorption of up to 70% or more at wavelengths of 400 nm and more than 70% of the infrared light reflectance at wavelengths of 800 nm. It was added to the coating to form a shield Role, to achieve the purpose of anti-UV aging and thermal aging, while increasing the thermal insulation of the paint. Through nano-particle filling method, the nano-silicon dioxide doped into the UV assimilation coating, significantly improved UV curing The hardness and adhesion of the coating also diminishes the extent to which UV absorbs the coating to absorb UV radiation, thereby reducing the rate of assimilation of the UV-enriched coating.
