Abstract

The invention discloses a kind of nano-TiOs2The TiO containing isopropyl alcohol dispersant ammonium is added in sodium metasilicate by surface hydrophobicity modification process2In slurry, by 10%H in a manner of spray2SO4It is added thereto, preparing surface precipitation has the TiO of silicic acid2Particle, in TiO2Surface forms one layer of SiO2Film.The present invention is to nano-TiO2Surface hydrophobicity is modified, and nano-TiO is made2The molecular bridge that specific function is generated with organic media, so as to improve the comprehensive performance of nanocomposite.

Description

Nano-TiO2Surface hydrophobicity modification process
Technical field
The present invention relates to a kind of nanometered disposal technique, especially a kind of Nanosurface hydrophobic modification technique.
Background technology
Nano-TiO is added in UV coatings2It can make UV coatings that there is bacteriostasis property, but influence the comprehensive performance of UV coatings.
Invention content
In view of the deficiencies of the prior art, the present invention proposes a kind of nano-TiOs for the comprehensive performance that can improve UV coatings2SurfaceHydrophobic modification technique.
The present invention is achieved through the following technical solutions technical goal.
Nano-TiO2Surface hydrophobicity modification process, thes improvement is that:Sodium metasilicate addition is contained into isopropyl alcohol dispersantThe TiO of ammonium2In slurry, by 10%H in a manner of spray2SO4It is added thereto, preparing surface precipitation has the TiO of silicic acid2Particle, fromAnd in TiO2Surface forms one layer of SiO2Film.
Compared with prior art, the present invention having the positive effect that:To nano-TiO2Surface hydrophobicity is modified, and nanometer is madeTiO2The molecular bridge that specific function is generated with organic media, so as to improve the comprehensive performance of nanocomposite.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Nano-TiO2The TiO containing isopropyl alcohol dispersant ammonium is added in sodium metasilicate by surface hydrophobicity modification process2In slurry, withThe mode of spray is by 10%H2SO4It is added thereto, preparing surface precipitation has the TiO of silicic acid2Particle, in TiO2Surface forms oneLayer SiO2Film.
