Compared with prior art, beneficial effects of the present invention are as follows：
The present invention touches type Formaldehyde decomposition catalyst using non-light and adulterates four acicular type zinc oxide crystal whisker.Four acicular type zinc oxide crystal whisker
It is that uniquely the whisker with stereoeffect holds very much because of its unique three-dimensional four needle-shaped three-dimensional structure in all whiskers so far
Easily realize being uniformly distributed in basis material, to isotropically improve the physical property of material, while it is more to assign material
The unique functional characteristic of kind, such as wear-resisting, enhancing, vibration damping, anti-skidding, noise reduction, suction wave, anti-aging, antistatic, antibacterial performance.
Common nano-titania photocatalyst can be detached electrons and holes by ultraviolet light excitation, and electronics is made
For activated centre, can in air oxygen and water function generate hydroxyl radical free radical, the superoxide anion isoreactivity factor, it is active because
Son has superpower chemism, and the pernicious gases such as energy decomposing formaldehyde, benzene, this is the mechanism of photocatalyst decomposing formaldehyde.But one
As there is no very strong ultraviolet light in domestic environment, therefore, add in coating, remove the effect of formaldehyde and unstable.This hair
It is bright using pass through transition metal ions (Fe3+, Cu2+) doping treatment nano zine oxide, contained by transition metal from
Electron absorption can be left electrified cavity (h that can not be compound by son+) and electronics (e-), the effect in activated centre is played, incorporation is worked as
Variable valency metal ions become ion (such as Fe of inferior stable state more and more due to absorbing electronics2+、Cu+), system again not
Stablize, to discharge electronics and become stable high valence ion (Fe3+, Cu2+).At this point, the electronics released becomes new work again
Property Central growing point, play depollution of environment active function.So cycle, achievees the purpose that long-acting purification air.In addition, transition is golden
The level structure for belonging to the also changeable zinc oxide system of ion doping, forms additional dopings energy level, is conducive to electrons and holes separation,
Be conducive to generate activated centre.Therefore, the four acicular type zinc oxide crystal whisker for the doping treatment that the present invention uses touches type first for non-light
Aldehyde distintegrant solves existing nano-titania photocatalyst decomposing formaldehyde and ultraviolet light is needed to trigger, and Formaldehyde decomposition efficiency is low
The problem of.
The present invention is using ultra-fine ground granulated blast furnace slag as inorganic coagulation material and formaldehyde adsorbent, active Blast Furnace Ore
Ground-slag specific surface area reaches 420m2The specific surface area of/kg, super large assign its powerful formaldehyde absorbing ability, the formaldehyde of absorption
The catalytic decomposition for touching type Formaldehyde decomposition catalyst by non-light again, achieve the purpose that it is long-acting remove formaldehyde, while it is again with inorganic
The activity of cementitious material can replace all or part of inorganic coagulation material, coating is made only to add the inorganic gels such as a small amount of cement
In the case of material, remaining to keep excellent water resistance and wash-resistant property, (adding the inorganic coagulation materials such as a large amount of cement will
Weaken the adsorption capacity of coating).
Specific implementation mode
With reference to embodiment, the invention will be further described, but it should be recognized that embodiment is not to this hair
Bright claimed range is construed as limiting.
