Abstract
The present invention relates to a kind of tebuconazole aqueous emulsion, the aqueous emulsion includes 10~30% Original Tebuconazoles, 10~25% dimethyl sulfoxide (DMSO)s, 5~15% dimethylformamides, 5~15% isooctyl acetates, 5~10% emulsifying agents and 45~65% water by mass percentage；During making, the dimethyl sulfoxide (DMSO) in its component, dimethylformamide and isooctyl acetate are squeezed into agitating device in the lump by mass percentage, Original Tebuconazole is added while stirring and dissolved, emulsifier for mixing is added uniformly, water is slowly added to afterwards and is well mixed.Using the present invention, show according to testing result, long lasting foam amount therein（Place 1min)/mL indexs are reduced to≤8, and other the key technical indexes keep constant, therefore in real process, can be easier to efficiently control the dosage of institute's medication in the case where using same spray volume（Concentration）, promote drug effect normally to play, and foam yield is small, excursion is small, and the number of times of allotment and time are reduced, so as to improve operating efficiency.
Description
Technical field
The present invention relates to a kind of tebuconazole aqueous emulsion, particularly 25% tebuconazole aqueous emulsion for preventing and treating pear scab.
Background technology
At present, the tebuconazole aqueous emulsion of in the market, its Chinese common name is Tebuconazole, and ISO is general entitled
Tebuconazole, chemical name is（ks）-1-（4 monochloro-benzene bases）- 4,4- dimethyl -3-（1H-1,2,4 ,-triazol-1-yl first
Base）Amyl- 3- alcohol, molecular structure is shown in accompanying drawing 1.Its component includes Original Tebuconazole, certain herbaceous plants with big flowers acid amides, emulsifying agent, antifreezing agent and water；It is above-mentioned
The preparation method of Tebuconazole is to add Original Tebuconazole in certain herbaceous plants with big flowers acid amides to dissolve, and adds emulsifier for mixing and uniformly constitutes oil phase,
Composition aqueous phase is mixed evenly in antifreezing agent, water, oil phase is slowly added to aqueous phase stirring mixing under high-speed shearing machine shearing
Uniformly.By tebuconazole aqueous emulsion made from above-mentioned component and method, show according to testing result, its long lasting foam amount（Place
1min)/mL index≤25, it is higher, when in the case of same spray volume, one is that more foam and change can be produced when using
Scope is big, is accomplished by reducing the amount for loading medicament in automiser spray accordingly and excursion is also big, accordingly, it is difficult to control used
The dosage of medicine（I.e. concentration is inaccurate）, such as dosage is too high easily to produce negative harm to biology, and dosage is too low, does not reach original
Prevent and treat the effect of pear scab；Two be relatively accurate in order to ensure the dosage of medicine, in addition it is also necessary to by froth breaking, the allotment of dosing again
Process, therefore time-consuming take a lot of work.
The content of the invention
It is an object of the invention to provide can improve long lasting foam amount（Place 1min)/mL indexs, so that in actual use mistake
Cheng Zhongneng more effectively controls the dosage of institute's medication（Concentration）, promote drug effect normally to play, and operating efficiency when using can be improved
A kind of tebuconazole aqueous emulsion.
The present invention is adopted the technical scheme that：A kind of tebuconazole aqueous emulsion, it is characterised in that by mass percentage including such as
Lower component：10~30% Original Tebuconazoles, 10~25% dimethyl sulfoxide (DMSO)s, 5~15% dimethylformamides, 5~15% acetic acid are different pungent
Ester, 5~10% emulsifying agents and 45~65% water.
Described a kind of tebuconazole aqueous emulsion, it is characterised in that its preparation method is：By mass percentage by its component
10~25% dimethyl sulfoxide (DMSO)s, 5~15% dimethylformamides and 5~15% isooctyl acetates squeeze into the lump in agitating device, side
Stir side and add 10~30% Original Tebuconazoles and dissolve, it is uniform to add 5~10% emulsifier for mixing, it is slowly added to 45 afterwards~
65% water is well mixed.
Using the present invention, show according to testing result, long lasting foam amount therein（Place 1min)/mL indexs are reduced to≤8,
And other the key technical indexes keep constant, therefore in real process, can relatively it hold in the case of using same spray volume
Easily efficiently control the dosage of institute's medication（Concentration）, promote drug effect normally to play, and foam yield is small, excursion is small, adjusts
The number of times matched somebody with somebody and time are reduced, so as to improve operating efficiency.
Brief description of the drawings
Fig. 1 is the structural formula of the present invention.
Fig. 2 is the quality control index of the existing product before the present invention.
Fig. 3 is the quality control index of the existing product of the present invention.
Embodiment
The present invention is described in further detail with reference to embodiment.It comprises the following steps：
First, the tebuconazole aqueous emulsion includes following component by mass percentage：10~30% Original Tebuconazoles, 10~25% 2
Methyl sulfoxide, 5~15% dimethylformamides, 5~15% isooctyl acetates, 5~10% emulsifying agents and 45~65% water.
2nd, its preparation method is：By mass percentage by 10~25% dimethyl sulfoxide (DMSO)s in its component, 5~15% diformazans
Base formamide and 5~15% isooctyl acetates are squeezed into agitating device in the lump, are while stirring added 10~30% Original Tebuconazoles
Dissolving, adds 5~10% emulsifier for mixing uniformly, and the water that 45~65% are slowly added to afterwards is well mixed.
3rd, the product quality that n times are carried out as tebuconazole aqueous emulsion in above-mentioned component and made from preparation method is detected, its
Quality control index result is as shown in figure 3, long lasting foam amount therein（Place 1min)/mL≤8 are substantially reduced.Therefore exist
In real process, it can be easier to efficiently control the dosage of institute's medication in the case where using same spray volume（Concentration）, promote
Enter drug effect normally to play, and foam yield is small, excursion is small, and the number of times of allotment and time are reduced, so as to improve work effect
Rate.
