The invented germicide possesses xtensive application fields and its production process is simple and cost is low.
Description
Technical field
It is solid-state with suspension liquid bactericide and preparation method thereof to the present invention relates to a kind of copper-loaded montmorillonite.
Background technology
Copper-based fungicide, fungicide are used widely in fields such as agricultural, aquacultures.Compare with organic synthesis bactericide, fungicide, the inorganic compound of copper has advantages such as safe, that antibacterial range is wide, the term of validity is long, as copper sulphate, Kocide SD etc.But on using, directly use copper-containing compound need expend a large amount of copper, be unfavorable for reducing production costs, in addition, excessive copper can be residual in soil, causes environmental pollution.The copper-loaded montmorillonite that the present invention relates to utilizes the slowly releasing effect of clay mineral, and the remaining electric charge of copper-loaded back mineral surfaces, has improved the biologically active of copper ion greatly, is the important improvement to existing copper-based fungicide, fungicide.Compare with traditional copper compound type antibacterial agent, it only contains a little copper element, and antibiotic effect obviously strengthens, and less to the negative effect of environment.
Summary of the invention
It is solid-state with suspension liquid bactericide and preparation method thereof to the purpose of this invention is to provide a kind of copper-loaded montmorillonite.
Bactericide is a kind of montmorillonite that contains commutative copper ion, and by weight percentage, the content of copper in montmorillonite is 0.5～6.5%.
Preparation method's step is as follows:
1) adopts na-montmorillonite; Perhaps, make na-montmorillonite through following steps through separating calcium base, the magnesium base montmorillonite of purifying:
A) montmorillonite adds water and stirs together with the sodium salt that is equivalent to the about 5-15% of ore weight, makes the suspension ore pulp of concentration about 10%;
B) under 40～100 ℃ of temperature, the ion-exchange reactions time is no less than six hours, during stir frequently;
C) behind the centrifugal or filtering means dehydration, water cleans 1-2 time;
2) add the mantoquita that copper content is equivalent to ore weight 2-10%, or its water-containing crystal salt, add the ore pulp that water is made concentration about 10% again, stir the back under 40～100 ℃ of temperature, the ion-exchange reactions time is no less than six hours, during stir frequently;
3) behind the centrifugal or filtering means dehydration, clean 1-2 time, and dehydration again;
4) the step 3) gains are cool naturally shines dryly, or dries being lower than under 80 ℃ of temperature, selects for use suitable equipment to be ground to less than 300 orders, obtains water content less than 10% powder, stand-by;
Perhaps: the step 3) gains add maximum 5% dispersant, add water and stir, and make the ore pulp of 10-30%, select for use suitable spray drying device to carry out drying, and the spray dryer EAT should be controlled at 150～180 ℃ of scopes; The discharging opening temperature is no more than 70 ℃, obtains water content less than 10% powder, and is stand-by;
Perhaps: step (3) gains add maximum 5% dispersant, add water and stir, and make the suspension of debita spissitudo again, and are stand-by.
Said sodium salt is sodium chloride, sodium nitrate, sodium sulphate.Mantoquita is copper sulphate, copper chloride, copper nitrate.Dispersant is a sodium tripolyphosphate, tetrasodium pyrophosphate, one or more in the sodium lignosulfonate.
Advantage of the present invention is:
1) utilize the cation exchange capacity (CEC) of natural montmorillonite to carry copper ion, production cost is low;
2) copper content is low in bactericide, the fungicide, has reduced the environment residual quantity;
3) slow-release capability of montmorillonite is renderd a service lastingly product sterilization, antifungal;
4) safe in utilization, applied widely.
Embodiment
The raw material that the present invention uses is the natural montmorillonite of purifying through separating, and has another name called bentonite.The purification technique of montmorillonite is well-known, and it comprises that pulverizing, making beating make suspension, classification and collect approximately steps such as particle less than 2 μ.This highly purified montmorillonite is the clay mineral of a kind of light green color, light yellow tool layered crystal structure.Separate purification process and can select conventional mining equiment for use.
Be applicable to that dispersant requirement of the present invention is not very strict.The dispersant of recommending to use is a sodium tripolyphosphate, one or more in tetrasodium pyrophosphate and the sodium lignosulfonate.The purpose that adds dispersant is the viscosity that reduces slurry, makes the atomized drying of high concentration slurry become possibility, thereby reduces energy consumption for drying; In addition, dispersant can increase the stability of suspension, delays its precipitation.
In manufacturing process of the present invention, it is not very strict that the water yield that relevant step is added requires, and under the prerequisite that equipment such as stirring, mixing and atomized drying can run well, should reduce water, to reduce production costs as far as possible.Stirring and mixing can be selected conventional equipment for use, and the time limit of mixing is advisable can form obviously uniform slurry.
Ion-exchange reactions is carried out in two steps, and the first step is used sodium salt solution, makes the Na in the solution
+Ca in the ion exchange montmorillonite mineral lattice
2+, Mg
2+With other interlayer cation, said sodium salt is sodium chloride, sodium nitrate, sodium sulphate.Second step was used copper salt solution, made the Cu in the solution
2+Na in the ion exchange montmorillonite mineral lattice
+With other interlayer cation, said mantoquita is copper sulphate, copper chloride, copper nitrate.The requirement of sodium salt and mantoquita usage amount is not very strict, and generally speaking, the sodium salt consumption is not less than 8% of montmorillonite dry weight, and copper content is not less than 2.5% of montmorillonite dry weight and is advisable in the mantoquita.
Copper-loaded later montmorillonite can be selected the conventional drying method for use, and baking temperature should be above 80 ℃; Also can the natural drying drying at the arid climate environment, again it is ground to granularity and is not more than 300 orders.
The most handy spray drying device of slurry carries out drying, and the spray dryer EAT is controlled at 150～180 ℃ of scopes, and the discharging opening temperature is no more than 70 ℃.Spray dried products is a kind of runny pressed powder.Being used for spray drying device of the present invention is routinely, and technical is well-known.
Preparation of the present invention has two types, and water content is less than＜10% pressed powder and contain the suspension of dispersant.Wherein the solid powder preparation copper content is generally between 2～3%.When dilute with water, swelling and mechanical agitation by montmorillonite are easy to form uniform aqueous dispersion.
Embodiment 1: the preparation of granular pattern copper-loaded montmorillonite bactericide, fungicide
