Description
Technical field
The present invention relates to board technology field, more particularly to a kind of hydrophobic impervious self-clean type plastic plate and its preparation side
Method.
Background technology
Titanium Dioxide is a kind of transition metal oxide while being also a kind of semi-conducting material, as which has preferable life
The thing compatibility, can resist chemical attack, the advantages of harmless, meanwhile, the material abundance of titanium source content makes Titanium Dioxide thing
Produce abundant and cheap, therefore obtained people and widely paid close attention to, the application of Titanium Dioxide is embodied in each that people live
Aspect, current Titanium Dioxide have reached world lead level without mechanical goods usage amount.Due to the characteristic of Titanium Dioxide, Ke Yizuo
For very important inorganic chemical industry material, thus its have in various fields such as national defence aviation industry, commercial production, hard-core technologies huge
Big power of influence and application.Titanium Dioxide can have color as Chinese white using titanium white production coating out again
Bright-coloured, colorability is strong, and the advantages of covering power is high, and its service life is longer compared with other pigment, therefore its usage amount accounts for institute
Have the 80% of Chinese white.Rather than the other Titanium Dioxide of pigment-level still has the field of being widely applied, be concentrated mainly on metallurgy,
The fields such as pottery, glass, sheet material；As Titanium Dioxide has the ability for absorbing ultraviolet and higher photocatalytic activity, therefore can
To prepare catalyst, adsorbent, antibacterial etc. using this characteristic, in the 70's of eighties of last century, people are found that to water
Middle interpolation Titanium Dioxide, under the irradiation of visible ray, water can resolve into oxygen and hydrogen.Subsequently, and special because of Titanium Dioxide
Some physicochemical properties and every excellent properties, so be widely used in numerous fields, including environment, the energy, information,
Material, health, building, medical treatment etc., especially in fields such as photocatalysis, solaode, gas sensor, sterilizations, embody very
Big researching value；
Nano titanium oxide has excellent photocatalytic activity, has quite varied application prospect, however, there is also some
Weak point, nano titanium oxide just must can play a part of catalyst under the promotion of ultraviolet light, and solar energy is produced
Great waste, which greatly limits the use of nano titanium oxide.So we are needed by modified this
Method improves utilization of the nano titanium oxide to solar energy, allows it to make full use of the light of visible region.Research shows, when subtracting
During the size of little titanium dioxide nanoparticle, its surface area, surface tension can be strengthened therewith with surface energy.Little chi is accordingly provided with
The characteristics such as very little effect, quantum size effect, skin effect, it is widely used various that these speciality also cause Titanium Dioxide to become
Inorganic material product；
Catalysis material improves the living environment of people, and we are can be not only used for using the photoelectric characteristic of catalysis material
Solaode is prepared, can be with degradation of contaminant, maintaining ecological balance.But the problem that needs are solved is, catalysis material
Can't more efficiently using solar energy, this causes energy transition rate low or the shortcomings of poor photocatalytic degradation efficiency；On the one hand
Shortage of resources, is on the one hand unable to effectively utilizes effective energy（Visible light part）, will all cause the extreme loss of resource.Cause
This, for how to improve problem of the Titanium Dioxide as photocatalysis efficiency, still needs to further study and improve；
Polyacrylate has pollution-free, low cost and other advantages, has obtained in fields such as building, automobile, packaging, printings more wide
General application, but there is also thermostability, hardness etc. poor the problems such as, limit to a certain extent its apply, using inorganic nano
Titania modified polyacrylate, can significantly improve the performances such as the hardness of polyacrylate, thermostability, impact strength, from
And further expand its use range；
However, as the specific surface area of nano titanium oxide is big, surface energy is high, in non-thermodynamics stable state, prepared answers
The shortcomings of easily there is nanoparticle reunion, composite poor storage stability, complicated process of preparation in condensation material.
