Description
Technical field
The invention belongs to anti-corrosion, the preparation method of abrasion resistant film, in particular to a kind of titanium dioxide with nanocrystalline structure,
Zirconium dioxide complex sol preparation method.
Background technique
Annual metal erosion causes heavy losses to national economy, and nano-titanium dioxide mentions metal with not sacrificing cathode
For electrochemical protection function, there is lubricating function, toughening functions, nano zirconium dioxide hardness is 9H, provides anti-corrosion function to metal
Can, the film quality of the two composition is close, smooth, and cracky, while providing protective layer for metal and does not provide electrochemical protection.Nanometer
The electron interaction of titanium dioxide and zirconium dioxide, colloid is more stable, and the functional advantage ratio of the film of formation is dosed more respectively
Add protrusion.
Summary of the invention
Complex sol provided by the invention, wherein the crystal form of nano-titanium dioxide is anatase titanium dioxide or rutile-type or is them
Mixed type, between pH value 3-5, the colloidal sol be it is colorless and transparent or light yellow translucent, concentration is 15%-20%.
Complex sol as described above, preparation method are, with titanyl sulfate and zirconium oxychloride cohydrolysis, wherein oxychlorination
The mass ratio of zirconium and titanyl sulfate is not less than 1:2, and after zirconium oxychloride and titanyl sulfate are first dissolved in water, 60 DEG C are heated 30 minutes,
Solution becomes clear, is swapped after cooling with strongly basic anionic resin, using glacial acetic acid as buffer, when pH value is
To get above-mentioned colloidal sol when 3-5.
Specific example 1:
It takes 20 grams of titanyl sulfates, 10 gram of eight water oxygen zirconium chloride to be added in 120 grams of water and be heated to 60 DEG C, heats while stirring, until
The transparent clarification of solution is added 10 grams of glacial acetic acid after cooling, spent ion exchange resin 201*7 carries out ion exchange, until pH value is
To get vitreosol when 3-5, vacuum distillation adjusts solid point to 15%-20%.
Specific example 2:
It takes 20 gram of eight water oxygen zirconium chloride, 10 grams of titanyl sulfates to be dissolved in 120 grams of water, is heated to 60 DEG C, heats while stirring, until
The transparent clarification of solution is added 10 grams of glacial acetic acid after cooling, spent ion exchange resin 201*7 carries out ion exchange, until pH value is
To get light yellow translucent colloidal sol when 3-5, vacuum distillation adjusts solid point to 15%-20%.
Titanium dioxide of the invention, zirconium dioxide complex sol are colourless or light yellow clear liquid, and partial size is 5-80 to receive
Between rice, pH value has excellent stability between 3-5, and Storage period is 6-12 months.
