Description
Technical field
The present invention relates to technical field of modification, specifically, being a kind of preparation side of novel terylene modifying titanium dioxide
Method.
Background technique
Titanium dioxide is important chemical fibre delustering agent, and general there are three types of crystal phases: brockite, rutile and Anatase.
Wherein, brookite is in transitional face, it is difficult to obtain；Rutile Type hardness is higher, is easy to cause to wear to filament spinning component, thus
Influence the service life of equipment and the quality of spinning；Anatase phase titanium dioxide source relative abundance, property are relatively stable, and are with it
Fiber made from delustering agent and natural fiber opacity are similar, thus at present delustering agent based on anatase titanium dioxide,
But it is irregular there is also dispersing in the melt, photocatalytic degradation reaction easily occurs, the problems such as function is more single, this is just to two
More stringent requirements are proposed for the production preparation of titanium oxide and modification technology.
Currently, frequently with the modified mode in surface to improve the dispersibility of titanium dioxide powder, and it is living to reduce its photocatalysis
Property etc., such as application No. is 201510669822.3 using 2,2- dihydromethyl propionic acid in alcohols solvent system, to calcined
Nano-titanium dioxide is modified, and is improved the dispersibility of titanium dioxide in a polymer matrix, is reduced its photocatalytic activity.
Summary of the invention
It is irregular there is dispersing in the melt to solve current titanium dioxide, easily occur photocatalytic degradation reaction, function compared with
The problems such as being single, the invention proposes a kind of modifying titanium dioxides and preparation method thereof, and preparation method is relatively simple, modified
Titanium dioxide have the advantages that antibacterial functions, changeable colour, good dispersion, photocatalytic activity are low etc..
It also proposed application of the modified titanium dioxide in terylene simultaneously.
The present invention is achieved by the following technical solutions: a kind of preparation method of modifying titanium dioxide is following steps:
(1) dipping of titanium dioxide
It is filtered after titanium dioxide powder is impregnated 15-30 min in the ethanol solution of silver nitrate, powder is dried；
Preferably, titanium dioxide powder is selected from anatase titanium dioxide powder, diameter of particle is 250-400 nm.It is sharp
Titanium ore type titanium dioxide source relative abundance, property are relatively stable, and using it as fiber made from delustering agent and natural fiber not
Transparency is similar
Preferably, the ethanol solution concentration of silver nitrate is 5-18 mmol/L, the quality of titanium dioxide contains in dipping system
Amount is 5-20%, and silver nitrate purity > 99%, ethyl alcohol is using dehydrated alcohol.
Preferably, first stirring ultrasound again before impregnation, be conducive to be uniformly mixed.
Preferably, dry using vacuum drying oven.
(2) reduction of nano-Ag particles
Powder after drying ultraviolet lighting is handled into 12 h or more, until taupe is presented in powder；
This is that the silver nitrate presoma on its surface is reduced to nano-Ag particles, and nano-Ag particles partial size is 15-20 nm,
Load quality is 0.1-0.5%.Nano-Ag particles have preferable anti-microbial property, and there are stronger electricity between titanium dioxide
Sub- transmitting effect, can influence the optical property of titanium dioxide.
Titanium dioxide powder colour developing is reversible in this step, can be extensive through treatment with ultraviolet light again after visible-light treatment develops the color
Multiple taupe, after be in again corresponding color through panchromatic light or monochromatic light processing.
(3) titanium dioxide powder surface coating modification
Ball milling after powder made from step (2), water, polyethylene glycol, auxiliary agent are mixed is changed after filtering, separation, drying
Titanium dioxide after property.
The usage amount of water is to stablize mixed liquor, uniform to measure.
Preferably, the mass ratio of powder and polyethylene glycol is 9-499:1, polyethylene glycol is used for titanium dioxide surface packet
It covers.
Preferably, the mass ratio of polyethylene glycol and auxiliary agent is 9-99:1.The auxiliary agent includes dispersing agent and antioxygen
Agent, wherein the mass ratio of dispersing agent and antioxidant is 1-9:1.Dispersing agent is selected from charge modifiers, preferably hexa metaphosphoric acid
Sodium, antioxidant are selected from butylated hydroxy anisole.
Preferably, Ball-milling Time is 2-5 hours, Ball-milling Time is unsuitable too long, serious through sedimentation removal reunion after ball milling
Particle.
Modified titanium dioxide is white in taupe, then after panchromatic light processing after ultraviolet light is handled, or
In corresponding monochromatic light color after monochromatic light processing, while there are antibacterial functions, and dispersibility is preferable in polyester fondant, light
Catalytic activity is lower.
Modified titania powder is again through wet ball grinding surface cladding polyethylene glycol to improve it in polyester fondant
Dispersibility.Therefore modifying titanium dioxide made from a kind of preparation method of modifying titanium dioxide of the present invention is on terylene
Application.There is the terylene of preparation antibacterial, different light sources to irradiate the multiple functions such as lower changeable colour, and after coated with polyethylene glycol
Dispersibility is preferable in polyester fondant, while reducing the activity of its photocatalytic degradation PET molecule.
Compared with prior art, the beneficial effects of the present invention are:
(1) preparation method is easy；
(2) modified titanium dioxide has the advantages that antibacterial functions, changeable colour, good dispersion, photocatalytic activity are low etc.；
(3) modified titania powder improves the dispersibility in polyester fondant in terylene, reduces its light
The activity of catalytic degradation PET molecule.
