Background technology
One of the problem of China's textile industry is faced is exactly that the scientific and technological added value of weaving face fabric is low.Current home textile fabric development
On the developing focus or flower pattern of worker, color matching and product style, the exploitation of functional fabric is ignored.And it is used as curtain face
Material is often exposed in sunlight and air, inevitably adheres to dirt, and textile fabric genus polyporus material, easily absorption
Mushroom, and the growth of bacterium easily causes cross-infection and spread disease, and produces peculiar smell, damages fiber, therefore, being badly in need of exploitation has
The window curtain fabric of automatically cleaning and sterilizing function.
The content of the invention
It is an object of the invention to provide a kind of preparation method of photocatalysis smelly eliminating automatically cleaning window curtain fabric, solve above-mentioned existing
One or more in technical problem.
A kind of preparation method for photocatalysis smelly eliminating automatically cleaning window curtain fabric that the present invention is provided, is comprised the steps of：
A1, weigh meso-porous titanium oxide powder, add the acetone soln for containing mass percent for 1-5% silane coupler
In, wherein the solid content of the titanium dioxide powder is 45-50%, stirred using agitator, afterwards ultrasonically treated 1-2h；Will
Above-mentioned mixed liquor, which is placed in 60-80 DEG C of vacuum drying chamber, dries 24-48h, is ground after taking-up, obtains particle diameter for 200-
300nm modification meso-porous titanium oxide powder；
A2, the silicon sol solution that solid content is 40-45% is prepared, the obtained modifications of A1 are added in silicon sol solution mesoporous
Titanium dioxide powder, is stirred afterwards, until modified meso-porous titanium oxide powder particle is uniformly dispersed, obtains mixed liquor；
A3, the quality that acrylic emulsion, the acrylic emulsion and the mixed liquor are added in the mixed liquor that A2 is obtained
Than for 1:1, after stirring, it is coated in base fabric, the thickness of the coating is 1-100 μm, and 50-60 DEG C is placed in afterwards
36-48h is dried in vacuum drying chamber, the photocatalysis smelly eliminating automatically cleaning window curtain fabric is obtained.
Photo-catalyst deodorization principle：Titanium dioxide is considered as most promising photochemical catalyst, the electronics knot of titanium oxide
Structure feature is full valence band and empty conduction band, and its band-gap energy is 3.2ev, it is necessary to which wavelength is less than 387.5nm ultraviolet light, electricity
Son, while producing corresponding hole in valence band, could form the electron-hole pair of high activity from valence to conduction band.Now
Will occur the H of redox reaction, hole and adsorption on surface2O or OH-Reaction forms the work with very strong oxidizing property
Property hydroxyl；Electronics then reacts with the oxygen molecule of adsorption, generates superoxide ion.Superoxide ion can further react with water, raw
Into perhydroxyl radical and hydrogen peroxide, these materials can react with large biological molecule such as lipid, protein, enzyme and nucleic acid molecule,
Directly damage or by a series of oxidation chain reactions, and cause extensive damaging fearness bad to biological cell structure, to reach
The effect of sterilization.By silane coupler modified, meso-porous titanium oxide can be well mixed in coating solution, be applied in base fabric
During cloth, it can be effectively dispersed in base fabric, to reach optimal photo-catalyst effect.
In some embodiments, the preparation method of meso-porous titanium oxide comprises the following steps：
B1, by TiO2·nH2Both O and KOH mol ratios are 0.6-0.8, add appropriate water, are ground, then in horse
Not it is warming up in stove after 500-600 DEG C and is incubated 2h, slow cooling obtains interphase K to room temperature2Ti4O9；
B2 and then by scattered intermediate product K2Ti4O7Put into a small amount of water, 24-36h is placed after grinding, then will
It is stirred in the product input suitable quantity of water of gained, 0.5mol/L hydrochloric acid is constantly added dropwise, the pH value of solution is controlled with acidometer
For 3.0-4.0；
B3, suction filtration goes out intermediate product after stable system reaches balance, is washed with water to neutral and dry to constant weight and produced
Thing metatitanic acid, then sinters to 400-450 DEG C in Muffle furnace, is incubated 2h, and slow cooling to room temperature obtains described meso-porous titanium oxide.
And meso-porous titanium oxide can increase the specific surface area of titanium dioxide due to its meso-hole structure, biology can be more effectively adsorbed
Macromolecular or mushroom, to carry out photo-catalyst, so as to strengthen the performance of its deodorization and sterilization.
In some embodiments, the particle diameter of Ludox is 100-120nm.
In some embodiments, the preparation method of Ludox comprises the following steps：
C1, by weight/mass percentage composition be 10% sodium silicate solution, by cationic ion-exchange resin, obtain active silicic acid；
C2, by weight/mass percentage composition for 10% active silicic acid add retort, in retort add KOH solution regulation
PH value is 9-11, is heated by vapor, and heating and temperature control is at 100-120 DEG C, and the heat time is 10-20h, obtains solid content
