The preparation method of glue.
Background technology
Aluminium magnesium silicate inorganic gel is to be modified the monodimension nanometer material formed through special process by natural montmorillonite, dispersible
Yu Shuizhong, forms thixotropy gel;System is generally translucent to transparent, is sheared or the effect of other external force recovers necessarily
Mobility.
Aluminium magnesium silicate inorganic gel is widely used in the fields such as daily use chemicals, medicine, pesticide, industry.
At present, the technology of preparing of natural montmorillonite processing inorganic gel is mainly wet method slurrying, thinner disperses, centrifugation divides
Product is obtained from purification, sodium modification and some other processing.
A large amount of well-regulated laminated structure aggregations are included in the powder form for the inorganic gel that natural montmorillonite processing obtains
Body, in aqueous the cationic charge of laminated structure Inter layer adsorption wafer surface, a large amount of water penetrations can be dragged to by electrostatic attraction
Laminated structure depolymerization is caused to interlayer swelling, is finally mutually lapped to form " card room formula " net structure, makes it have good increasing
Consistence, suspension, thixotropy etc., in the field extensive use such as cosmetics, toothpaste, medicine, pesticide, coating.
But calcium-base bentonite, during aluminium magnesium silicate inorganic gel is processed, it is difficult to be lifted there are viscosity, or after drying again
The phenomenon that aquation viscosity declines, constrains the application of aluminium magnesium silicate inorganic gel;In addition, the hydrophily of aluminium magnesium silicate inorganic gel
By force, the phenomenon that powder is united occurs in aqueous dispersion, causes jitter time in aqueous systems elongated, the life to application producer
Production efficiency and production cost impact;Therefore, it is necessary to develop it is a kind of can in aqueous dispersion rapid dispersion aluminium-magnesium silicate
Inorganic gel materials.
The content of the invention
For solve the deficiencies in the prior art, it is an object of the invention to provide a kind of high dispersibility high viscosity aluminium-magnesium silicate without
The preparation method of machine gel.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
A kind of preparation method of high dispersibility high viscosity aluminium magnesium silicate inorganic gel, comprises the following steps:
S1, powder, aluminium-magnesium silicate raw material is crushed;
S2, modification, above-mentioned powder and modifying agent, water are mixed by certain mass percent and ore pulp are made;
S3, purifying, using the Dynamic Separation method of purification of centrifugal force field, separating-purifying ore pulp, takes suspension;
It is S4, compound, it is high-pressure homogeneous multiple after being polynary mineral by suspension and the functional mineral of certain mass percent compounding
Close;
Product after S5, dry above-mentioned homogeneous, is made inorganic gel product.
Raw material in above-mentioned steps S1 is natural montmorillonite, and the raw material granularity after crushing is 2mm-5mm.
The concentration of ore pulp in above-mentioned steps S2 is 7-12wt%, and modifying agent is a kind of or at least two combinations sodium salts, is used
Measure as the 1-5% of aluminium-magnesium silicate quality.
Separation factor in above-mentioned steps S3 is 500-2500, disengaging time 5-20min.
Functional mineral in above-mentioned steps S4 is sepiolite, one or both of attapulgite, Chun Du≤96%;It is multiple
Resultant pressure is 100-200MPa.
Drying in above-mentioned steps S5 is vacuum freeze drying, and drying temperature is -40 DEG C -30 DEG C.In vacuum refrigeration state
Under, by the distillation of hydrone by moisture removal, maintain the physical arrangement and molecular structure of aluminium magnesium silicate inorganic gel.
The invention has the beneficial effects that:
A kind of preparation method of high dispersibility high viscosity aluminium magnesium silicate inorganic gel of the present invention, by compounding functional mineral,
By high pressure homogenizing by polynary mineral sequential combination, acted on using the bridge chain of sepiolite, the fibre structure of attapulgite, to swollen
" card room formula " net structure that aluminium magnesium silicate inorganic gel prepared by profit soil is formed in aqueous dispersion realizes that mutually overlap joint is filled out
Fill, form more closely knit, more stable " card room formula " three-dimensional net structure;Compared with conventional aluminium magnesium silicate inorganic gel, it 5%
Aqueous dispersions viscosity improves 200-300mpa.s after static 24h;
By vacuum freezing drying dehydration, subliming water of removing, maintain aluminium magnesium silicate inorganic gel physical arrangement and
Molecular structure, thus there is excellent rehydration, can be with the state before recovering dry in the short time in aquation;Can be by silicic acid
1% water jitter time of magnalium inorganic gel is reduced to 3min from 5-15min, considerably reduces aquation jitter time.
A kind of preparation method of high dispersibility high viscosity aluminium magnesium silicate inorganic gel of the present invention, its step is simple, Yi Shi
Apply, manufacturing cost is low, and compared to existing aluminium magnesium silicate inorganic gel, significant effect, has very strong practicality and widely fit
The property used.
