Description
Technical field
The present invention relates to technical field of pesticide, more particularly to a kind of Ficam wettable powder and preparation method thereof.
Background technique
Ficam (bendiocarb) is a kind of insecticide, and sterling is white solid, is soluble in acetone, dimethyl sulfoxide.
The Ficam phenol that can be generated by pyrogallic acid and 2,2-dimethoxypropane effect, reacts with methyl isocyanate and produces.It is right
Pest have tag, stomach poison function, be mainly used for preventing and treating cockroach, cricket, ant, the sanitary insect pests such as bedbug, also can be used as at soil
Reason prevention and treatment subterranean pest-insect.
The main dosage form of Ficam is suspending agent in the prior art, and suspending agent is a kind of thermodynamic unstable system, can not
It is made into high-content preparation, storage ability is poor, and effective component is degradable.Ficam is dry suspending agent there are also a kind of dosage form,
Formula is complicated, and production and processing difficulty is big, and the dehydration and drying step especially in preparation process needs high temperature, is easy to cause in formula
Ficam melting, auxiliary agent desorption seriously affects product quality.
Summary of the invention
The object of the invention is that overcome above-mentioned deficiency, a kind of Ficam wettable powder and preparation method thereof is provided.
In order to achieve the above objectives, the present invention is implemented according to following technical scheme:
A kind of Ficam wettable powder, component include: to be calculated by mass percentage, Ficam raw medicine 10%~80%, wet
Moisten agent 2%~8%, dispersing agent 2%~6%, urea 0%~60%, remaining is filler；Wherein hundred meter of Ficam raw medicine folding.
Preferably, the wetting agent component includes being calculated by mass percentage, alkylnaphthalene sulfonate 60%~100%, sulphur
Base dioctyl succinate sodium 10%~15%.
Preferably, the dispersant component includes being calculated by mass percentage, Negel formaldehyde condensation products
> 88%, sodium sulphate < 12%, water < 2%, naphthalene < 0.002%.
Preferably, urea is used when Ficam raw medicine mass fraction is less than 75%.
Preferably, the filler is white carbon black.
The invention also includes the preparation methods of Ficam wettable powder, comprising the following steps:
S1, level-one are stirred: Ficam raw medicine, wetting agent, dispersing agent, urea, filler being mixed, uniformly mixed
Close material；
S2 is crushed: the obtained mixture of step S1 is crushed using airslide disintegrating mill, obtains mixing fines；
S3, second level are stirred and pack: mixing fines being continued to be stirred, obtains Ficam wettable powder；Then will
Ficam wettable powder is fitted into water soluble bag, obtains finished product.
Preferably, the mixing fines of the step S2 mixing fines that fineness requirement is 99% or more after air-flow crushing
74 microns of sieves can be passed through.
Action principle of the invention:
Ficam wettable powder prepared by the present invention has only used Ficam raw medicine, wetting agent, dispersion in the formula of the pulvis
Agent and filler.From the point of view of formula, the Ficam content of the formula is 10%~80%, and the high-content that can be prepared into Ficam can
Wet powder.Three kinds of wetting agent, dispersing agent, filler auxiliary agents, Ficam raw medicine and above-mentioned auxiliary agent have been used in formula of the invention
It is mutually attached together after mixing, so that Ficam wettable powder stability of the invention is more preferable, is more suitable for storing and transport.
The Ficam wettable powder that the present invention is prepared is packed using water soluble package i.e. water soluble bag, and when application is direct by medicine bag
It puts into water, medicine bag dissolves in 60 seconds, and pulvis is naturally fallen in water, and the avoidable dust of this packaged form is elegant to cause drug unrestrained
Take, reduces the health hazard and environmental pollution to operator.
Mixing stirring device and air flow crushing device are only used in preparation process of the invention, whole process only needs
The raw material of each component are stirred by level-one, are crushed, second level is stirred and packaging and other steps can obtain finished product.System
Preparation Method is simple to operation, whole process less energy consumption, and is not related to high-temperature operation step in preparation process, can guarantee
The stability of effective component Ficam guarantees product quality.
Compared with prior art, the invention has the benefit that
Ficam wettable powder of the invention, effective component Ficam stability is good, can store for a long time；Preparation of the invention
Journey is simple to operation, and whole preparation process is not necessarily to hot conditions, avoids the melting of Ficam raw medicine, auxiliary agent desorption, it is ensured that at
Quality；Using water soluble bag packaged form, avoid dust it is elegant caused by medicament waste, environmental pollution and application safety ask
Topic；Every quality index of Ficam wettable powder of the invention meets World Health Organization's WHO standard, and pharmacodynamic test proves
There is preferable insect killing effect to pests such as mosquito, fly, cockroaches.

Survey project includes Ficam active constituent content, wet screening fineness, suspensibility, holds bubble property, wettability.The mark that above-mentioned detection is relied on
Quasi- file difference is as follows:
1, Ficam active constituent content: " Ficam effective component qualitative test " (232/WP/ (M)/2, CIPAC is used
Handbook D, p.12,1988)；" test of Ficam content analysis " (232/WP/ (M)/3, CIPAC Handbook D,
P.12,1988).
2, it wet screening fineness: uses " measurement of fineness " (MT 185, CIPAC Handbook K, p.149,2003).
3, the suspensibility: " measurement of suspensibility；" (MT 184, CIPAC Handbook K, p.142,2003).
4, bubble is held: " measurement of persistent foamability " (MT 47.3, CIPAC Handbook F, 2013).
5, wettability: " measurement of wetting time " (MT 53.3.1, CIPAC Handbook F, p.165,1995).
Can be seen that be prepared wettable powder indices according to the present invention qualified from Fig. 1 to Fig. 6, effectively at
Divide content up to standard, suspensibility is high, and MEBO ribbon gauze is short.Know that the final product quality that the present invention obtains is stablized.
Certain disease is entrusted according to " GB/T 13917.1-2009 agriculture chemical registration with hygienic insecticide indoor pharmacodynamic test and evaluation "
Sick prevention and control center carries out indoor pharmacodynamic test come the product prepared to the embodiment of the present invention 1 to embodiment 6.
Using housefly, Culex pipiens pallens, Groton bug as test worm, wherein using 120mg for housefly and Culex pipiens pallens
a.i./m2Dosage, to Groton bug use 300mg a.i./m2Dosage tested.After medicament is watered dilution,
It is even to be applied in three kinds of test plate faces, for testing after air-drying.It is primary every 15d test, until when being tested as defined in three kinds of plate faces
Between.Glass plate (not sorbent surface) tests 90d, varnish plate (semi-absorbing surface) test 60d, lime plate (sorbent surface) test
45d, such as testing certain test worm at the appointed time, (blattaria 72h) death rate is lower than 70% for 24 hours to certain panel.Then the panel is not
It is further continued for testing.
Test method: using contactor is forced, test worm is put between forced contactor baffle and pulling plate, is restored to test worm
After normal activity, pulling plate is pulled out in the case where not injuring test worm, test worm is forced with absorbent cotton and contacts, and timing immediately is forced and connect
After touching 30min, whole test worms are transferred to clean support and are doted in cage, feeding standard is restored, record test worm mosquitos and flies (blattaria for 24 hours
72h) death toll, the test worm that 30min does not go down are included in test worm number living.It tests in triplicate every time, and does blank control simultaneously
Group.
Fig. 7 to Figure 12 is embodiment 1 to the test result of embodiment 6, and Figure 13 is evaluation criterion.
