Abstract
The present invention is the preparation method that a kind of mineral feed takes off mould dose, and this method is using attapulgite as primary raw material, and a small amount of tourmaline is as skeleton, while the addition of rectorite, tourmaline can effectively reduce the secondary agglomeration of atapulgite fibres after wet ball grinding.Then atapulgite fibres surface is made to form micro- organic phase by organically-modified, it is easier to dissolve in micro- organic phase according to solute theory of distribution liposoluble substance, micro- organic phase will not influence the common absorption of attapulgite because of its small volume substantially simultaneously, it is equivalent to and provides a kind of absorption driving force for attapulgite, the absorption reduced to the absorption of liposoluble substance to water-soluble substances can be improved to a certain extent.Because mycotoxin is mostly fat-soluble, need through the nutrient that feed supplements to be mostly water solubility, present invention can apply to feeds to take off mould field.
Description
Technical field
The invention belongs to non-metal ore advanced processing technical areas, and in particular to a kind of mineral feed takes off mould dose of preparation side
Method.
Background technique
Attapulgite is a kind of aluminium silicate mineral of aqueous rich magnesium with rhabdolith structure, is mineralogically subordinate to
In sepiolite group, stick crystalline substance is about 1-5 μm, and diameter about 20-70nm is natural monodimension nanometer material.Due to unique one-dimensional
Nanostructure and cellular structure, attapulgite have been assigned special physicochemical properties, have in absorbent fields and answer extensively
With.With the continuous development of adsorbent, people put forward new requirements adsorbent --- selective absorption.Such as it is de- in feed
Mould field, people require adsorbent improving the absorption reduced to the greatest extent while the absorption to mycotoxin to nutrient.Cause
This by attapulgite be used in preparation have selective absorption take off mould dose aspect can further expand its application.
CN105253947A discloses one kind by medical stone, six ring stones, diatomite, tourmaline, zeolite, montmorillonite, bumps
Natural minerals water purification mineralising Ceramic Composite made of stick stone, rectorite, sericite are finally sintered by mixing granulation drying
Material, in drinking water pollutant and heavy metal have good suction-operated.The composite material by high temperature sintering and
At there is no more loose structure is formed because interaction occurs for high temperature, high temperature can destroy different components instead
The structures of component mineral, specific surface area is greatly lowered, thus may decline to the adsorption capacity of mycotoxin.It is high simultaneously
Temperature energy consumption, can make increased costs.
CN106721945A, which is disclosed, a kind of takes off mould dose using attapulgite, tourmaline, iron tailings and sorbic acid as raw material.
By carrying out granularity downgrade processing respectively to raw mineral materials, then mixed sintering is mixed to get with sorbic acid solutions again takes off mould dose.
Although this, which takes off mould dose, has the effect of wide spectrum detoxification, secondary agglomeration can occur for when attapulgite downgrade processing, need to add
Grinding aid may cause secondary pollution, while need high-temperature process after its mixing, and power consumption energy consumption is at high cost.
Summary of the invention
It is an object of that present invention to provide the preparation method that a kind of mineral feed takes off mould dose, this method is main with attapulgite
Raw material, a small amount of tourmaline is as skeleton, while the addition of rectorite, tourmaline can effectively reduce concave convex rod after wet ball grinding
The secondary agglomeration of mineral wool.Then so that atapulgite fibres surface is formed micro- organic phase by organically-modified, distributed according to solute
Theoretical liposoluble substance is easier to dissolve in micro- organic phase, while micro- organic phase will not influence attapulgite because of its small volume substantially
Common absorption, be equivalent to and provide a kind of absorption driving force for attapulgite, can be improved to a certain extent to fat-soluble
The absorption of substance reduces the absorption to water-soluble substances.Because mycotoxin is mostly fat-soluble, the nutrition supplemented by feed is needed
Element is mostly water solubility, and present invention can apply to feeds to take off mould field.
Technical solution of the present invention is achieved as follows:
A kind of mineral feed takes off mould dose of preparation method, and the process of this method is:
1) attapulgite, rectorite and tourmaline are weighed, wet ball grinding mixing, 500~1000r/min of revolving speed, ball milling 8~
12h, drying, grinding obtain mixture；
2) it weighs quaternary cationics to be add to deionized water, in 50~100 DEG C of heating stirrings to complete
It is dissolved in water entirely, the mass ratio of the attapulgite and quaternary cationics is 50:1~5:1；
3) mixture for obtaining step 1) is added in the quaternary cationics solution that step 2) obtains,
It is made into suspension, the mixed processing under 50~100 DEG C of waters bath with thermostatic control, mixed processing is stir process or ultrasonic treatment, when stirring
Between be 1-6h, ultrasonic time be 10~90min；
4) it after mixed processing, is centrifuged under the revolving speed of 2500~5000r/min, removes supernatant, use deionized water repeatedly
Washing to halogen ion-free, drying, ground 200 mesh obtains mineral feed and takes off mould dose.
A kind of mineral feed takes off mould dose, this is taken off mould dose and is made using above-mentioned preparation method.
A kind of feed adds above-mentioned mineral feed in the feed and takes off mould dose, and the mineral feed takes off mould dose by mass fraction
0.01~0.8% is added in complete feed.
After adopting the above technical scheme, the present invention has the following beneficial effects:
1, step of the present invention is simple and easy, three kinds of raw mineral materials while wet ball grinding, and it is organic then to carry out quaternary ammonium salt together
Modified, effective process simplification saves cost, does not influence to improve the adsorption capacity for taking off mould dose while palatability, fits
Close large-scale production.
2, mineral feed prepared by the present invention, which takes off mould dose, has selective absorption.In practical applications, existing in the market
Adsorbent often also nutrient in a large amount of adsorption feed while absorbing mycotoxin, reduces the quality of feed,
Cause great waste.Animal needs to be mostly water-soluble (lysine, methionine, dimension life by the nutrient that feed supplements
Plain C, vitamin B2 etc.), the main mycotoxin for polluting feed is fat-soluble (aflatoxin B1, zearalenone etc.),
The quaternary surfactant that the present invention is added is adhering closely to fiber surface by ion exchange, and passes through hydrophobic interaction
Micro- organic phase is formed, does not influence even to reduce to nutrient (water while realizing high absorption (fat-soluble) on mycotoxin
Dissolubility) absorption, efficiency can be improved in practical applications, avoid wasting, save the cost.
3, the present invention carries out fiber dissociation to attapulgite by wet ball grinding, separates bundles of fiber, in this way may be used
To improve the specific surface area of mineral, adsorption capacity is promoted；Tourmaline and rectorite are introduced simultaneously, in fiber dissociation, on a small quantity
Tourmaline, rectorite enter among the fiber of dispersion as skeleton, are interspersed between attapulgite, effectively inhibit concave convex rod
Secondary agglomeration of stone during drying, at the same also avoid plus grinding aid caused by secondary pollution, it is attapulgite, electrical
Stone, rectorite have chemiluminescence.In addition to this, tourmaline also has the function of discharging negative ions radiation far infrared,
The surface tension of water can be reduced, activating and purifying water promotes the metabolism of animal, immunity of organisms is improved, to improve fowl
The quality of poultry.
