It was found from Tables 1 and 2, the aqueous woodware paint with purification air and sterilizing function in embodiment 1-8 removes formaldehyde
Ability and sterilizing ability are superior to comparative example 1-2, empty mainly due in embodiment 1-8, having purification compared with comparative example 1
The aqueous woodware paint of gas and sterilizing function includes ceria, Ti4+The ionic radius (about 60.5pm) of ion is far smaller than Ce4 +The ionic radius (about 103.4pm) of ion, Ti4+Ion can enter ceria (CeO easily2) lattice, so as to cause electricity
Lotus is uneven, due to charge unbalance, can adsorb more hydroxide ions, hydroxide ion obtains nanometer titanium dioxide
More hydroxyl free radicals are formed after the electronics of titanium release, so as to improve the photocatalytic activity of nano-titanium dioxide, further
Improve the oxygenolysis organic pollution of hydroxyl free radical and kill the ability of bacterium.Although containing ceria in comparative example 2,
But lotion is a lack of, titanium dioxide cannot disperse well, titanium dioxide may be caused to flocculate, the nano-titanium dioxide after flocculation
Particle diameter be no longer nanoscale, therefore, without photocatalytic activity.
Embodiment 1 is compared with embodiment 2, it can be seen that has the Waterborne wood of purification air and sterilizing function in embodiment 2
Device paint is better than embodiment 1 except formaldehyde ability and sterilizing ability, can be further due to adding the reason of auxiliary agent in embodiment 2
Prevent titanium dioxide from flocculating, ensure that titanium dioxide is constantly in Nano grade, improve photocatalytic activity.
Embodiment 1 is compared with embodiment 3, it can be seen that has the Waterborne wood of purification air and sterilizing function in embodiment 1
Device paint is better than embodiment 3 except formaldehyde ability and sterilizing ability, it may be possible to impure since the activity of anatase titanium dioxide is higher
Fewer, crystal form does not have rutile stabilization, it is easier to active electronics is produced by photocatalysis.
Embodiment 1 is compared with embodiment 4, it can be seen that has the Waterborne wood of purification air and sterilizing function in embodiment 1
Device paint is better than embodiment 4 except formaldehyde ability and sterilizing ability, it may be possible to since the particle diameter of anatase-type nanometer titanium dioxide is smaller
When, it is easier to active electronics is produced by photocatalysis.
Embodiment 2 is compared with embodiment 5, it can be seen that has the Waterborne wood of purification air and sterilizing function in embodiment 2
Device paint is better than embodiment 5 except formaldehyde ability and sterilizing ability, it may be possible to since dispersions of polyurethanes is compatible with nano-titanium dioxide
Property it is fine, in dry solidification, moisture can evaporate woodcare paint from paint film, form pore, in Nanometer Titanium Dioxide Hydrosol,
Hydrone and nano-titania particle compatibility are fine, during moisture evaporation, can carry nano-titania particle and reach paint film
Surface, so that avoid nano-titanium dioxide from being wrapped up completely by dispersions of polyurethanes, it is larger range of more to be held by illumination, release electronics
Easily.
Embodiment 1 is compared with embodiment 8, it can be seen that has the Waterborne wood of purification air and sterilizing function in embodiment 1
Device paint is better than embodiment 8 except formaldehyde ability and sterilizing ability, it may be possible to since ceria is without pre-treatment, ceria molecule
It is difficult to it is attached to the reason of titanium dioxide nanoparticle.
Above in association with most preferred embodiment, invention has been described, but the invention is not limited in implementation disclosed above
Example, and the modifications that essence carries out various according to the present invention, equivalent combinations should be covered.
