Description
Technical field
The invention belongs to ceramic field, more particularly to a kind of aluminum oxide ceramic membrane and its system with super hydrophobic surface
Preparation Method.
Background technology
With developing rapidly for membrane separation technique, all kinds of membrane materials are widely used in the fields such as food, medicine, biochemistry,
Requirement of the people to membrane structure, performance also improves constantly.The seperation film used at present in industrial production, daily life is mostly high score
Sub- material, including polytetrafluoroethylene (PTFE), polypropylene etc., belong to the polymer of organic monomer, this kind of film has quick solidifying, prepares letter
The advantages that single.But due to the characteristic of high polymer material in itself, film is easily swelled, aging, and irreversible deformation occurs, in harshness
Less stable in environment.By contrast, ceramic membrane is due to excellent heat endurance, chemical stability and being readily cleaned again
The advantages that raw and be that numerous scholars are of interest, be used widely at present in fields such as food, medicine, chemical industry, metallurgy, particularly
Played a significant role in water treatment field.
The content of the invention
It is an object of the invention to provide a kind of good aluminum oxide flat ceramic with super hydrophobic surface of chemical stability
Film and preparation method thereof.
In order to realize above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of aluminum oxide ceramic membrane with super hydrophobic surface, it is characterised in that first by alumina powder and fluxing agent
Mixing, using titanium sulfate as presoma, is modified Membranes On Alumina Particles Surface；Then inversion of phases the tape casting and high temperature sintering are used
Prepare ceramic membrane；Ceramic membrane is finally used into microwave radiation technology, surface grafting fluorosilicone, obtains the oxidation with super hydrophobic surface
Aluminium ceramic membrane.
The described aluminum oxide ceramic membrane with super hydrophobic surface, it is characterised in that its by following steps prepare and
Into：
（1）By kaolin, zinc oxide with 1：0.9-1.1 mass ratio mixing, is placed in 80-90 DEG C of vacuum drying chamber and dries 5-
6h, then through wet ball grinding, drying, pulverize and sieve to obtain the mixed-powder of 200-250 mesh, it is stand-by；
（2）By alumina powder and mixed-powder with 1：0.02-0.03 mass ratio is placed in reaction vessel, is added equivalent to oxygen
Change the deionized water of 15-20 times of aluminium micropowder weight part, ultrasonic vibration 50-60min, make its fully dispersed, sulphur is added dropwise while stirring
Sour titanium solution, magnetic agitation 30-40min, is then added dropwise ammoniacal liquor and adjusts the pH value of system to 9.5-10.5, continue magnetic at room temperature
Power stirs 2-3h, filtering, washing, dries, obtains surface modification alumina powder；
（3）By polyether sulfone, polyvinylpyrrolidone and 1-Methyl-2-Pyrrolidone with 1：1.5-1.8：6-8 mass ratio mixing,
It is placed in ball mill, drum's speed of rotation at the uniform velocity stirs 1.5-2h under conditions of being 300-400r/min, forms uniform and stable gather
Compound mixed liquor；The surface modification alumina powder of 2-3 times of parts by weight is added, drum's speed of rotation is 600-800r/min condition
Lower ball milling mixing 6-8h, obtains homogeneous ceramic slurry；
（4）By ceramic slurry by froth in vacuum after, pour into curtain coating grinding tool material fluid bath in, adjust knife away from, control scraper lead
It is 2-3m/min to draw speed, uses the smooth polyester film in surface as carrier band, and the ceramic slurry in groove is evenly laid out in carrier band
Surface；
（5）The film strips level being cast is immersed in coagulating bath, standing 20-24h makes its curing molding, then takes out in air
Middle dry 40-48h, dried raw embryo body cuts into required size, is put into Muffle furnace, with 2-3 DEG C/min heating rate
Temperature programming is incubated 5-6h, is cooled to 500 DEG C with 4-5 DEG C/min rate of temperature fall, naturally cools to room to 1450-1550 DEG C
Temperature, obtain ceramic membrane；
（6）By 17 fluorine decyl triethoxysilanes, deionized water and absolute ethyl alcohol with 1：4-5：95-100 mass ratio mixing,
Magnetic agitation 5-6h at room temperature, obtain silicon fluoride solution；By the quiet stain of ceramic membrane in silicon fluoride solution 20-24h, take out, be placed in
Microwave heats 50-60s in micro-wave oven；Again will by the quiet stain of ceramic membrane in silicon fluoride solution 20-24h, take out, be placed in micro-wave oven
Microwave heats 50-60s；Dried in 90-100 DEG C of vacuum drying chamber, obtain a kind of aluminum oxide flat board with super hydrophobic surface
Ceramic membrane.
The preparation method of the described aluminum oxide ceramic membrane with super hydrophobic surface, it is characterised in that step（2）In
Titanium and the mass ratio of aluminum oxide are 1 in titanium sulfate solution：200-250.
The preparation method of the described aluminum oxide ceramic membrane with super hydrophobic surface, it is characterised in that step（4）'s
Knife is away to scrape distance of the edge of a knife away from polyester film, and knife is away from for 0.5-0.6mm.
The preparation method of the described aluminum oxide ceramic membrane with super hydrophobic surface, it is characterised in that step（5）'s
The environment of Muffle furnace high-temperature calcination is atmospheric atmosphere.
The preparation method of the described aluminum oxide ceramic membrane with super hydrophobic surface, it is characterised in that step（6）'s
The power of micro-wave oven is 700-800W.
By above-mentioned technical scheme, the beneficial effects of the invention are as follows：
