Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and a part for constitution instruction, the reality with the present invention
Apply example to be used to explain the present invention together, be not construed as limiting the invention.In the accompanying drawings：
Fig. 1 is present invention process flow chart；
Embodiment
As shown in figure 1, prothioconazoles and the aqueous suspension agent formula of pyraclostrobin 30%, its step are as follows：
Prothioconazoles and the aqueous suspension agent formula of pyraclostrobin 30%, its step are as follows：
S1, by the prothioconazoles active compound (purity 96%) of quality 15.8%, 15.8% pyraclostrobin, (purity is
96%), 6% BP/CC wetting dispersing agents, 6.5% propane diols (antifreezing agent), 0.3% aluminium-magnesium silicate (thickener),
0.15% xanthans (thickener), 0.5% bactericidal agent and the mixing of 54.95% deionized water；Wherein, the BP/CC points
Powder acrylate copolymer and EO/PO block polymers composition.
The selection of wetting dispersing agent agent：In order to resist thermodynamic unstable system, increase the stability of suspending agent, must add
A certain amount of surfactant, its effect are that protective layer is formed around the pesticide granules in suspending agent, hinder suspending agent middle peasant
Medicine particle phase inter coagulation, so that pesticidal solid microparticle, is evenly dispersed in each position in suspension system, under study for action
Need to consider the various problems such as crystallization, aggregation, sedimentation.The reasonable employment of surfactant is the pass for solving these problems
Key.According to the above and the theory and prothioconazoles of suspending agent stabilising system and the physicochemical property of pyraclostrobin active compound, this hair
Bright priority carries out experiment sieving from domestic and international all multi items auxiliary agents.For appearance luster is bad, auxiliary dosage is big, produces wadding
Coagulate, be even difficult to grind, the auxiliary agent that particularly heat storage stability can't pass is eliminated.As a result show to use compound wetting and dispersing
Agent BP/CC, process of lapping is very smooth, no flocculation, and particularly heat storage product property indices reach requirement.Experimental result
It see the table below.The effect of different wetting agent see the table below：Wherein, -- represent " very poor " ,-" poor " is represented ,+" general " is represented, ++ represent
" medium ", ++ represent " good "
The selection of thickener：The viscosity height of suspending agent, is a key factor for influenceing product bin stability.Suitably
Viscosity can make product that there is good stability and very high suspensibility.Viscosity is too low, and preparation stability is poor, and viscosity is too high,
Then product is not easy to flow, and brings extreme difficulties to production and influences the use of product.In order to preferably improve the pourability of product,
Particle velocity is reduced, improves suspensibility and bin stability, product viscosity must be made in stable scope.Basis of the present invention
In the experience of industrialized production suspending agent, many stability tests are done on screening thickener, with No. BB-203 formula for base
Plinth, it is screened, determine that No. BB-204 formula XG (xanthans) and SB (aluminium-magnesium silicate) collocation using effect are preferable, entirely
System indices are stable, and its result is listed in the table below：
The selection of antifreezing agent：The suspending agent is using water as decentralized medium, is had in storage process low by severe cold
Wen Hou, remain to keep its stability.In order to prevent product from freezeout occur in storage, transportation, using effect is influenceed.
The present invention has selected several different antifreezes to be tested, and can reach when making antifreezing agent from ethylene glycol and propane diols
Performance requirement, it is economically relatively inexpensive to calculate ethylene glycol, from environmental requirement consideration with propane diols preferably, its result such as following table：
Prepare the selection of water：Effective content concentration is high in the formula system, and water occupies a small amount of part, in order to ensure that product exists
Drug effect is played stably during smooth, storage, the still stable and use of transport product are ground in processing.The present invention has selected difference
Water quality carried out lot of experiments, recognize different quality in this process, have influence on the whole process of lapping of the aqueous suspension agent.It is special
The other smooth degree to grinding plays great role, other performance indications is influenceed little.By the side using measurement electrical conductivity
Formula final choice deionized water, can reach performance requirement, pure water is slightly worse.Its result such as following table；
The selection of defoamer：All multi-products have a large amount of foams to produce in process of lapping, need to add proper quantity of defoaming agent.This hair
The bright experience by accumulating in conventional formula development, in the formula system during selective wetting dispersant, set comprehensively
Meter, by the adjustment of wetting dispersing agent, almost accomplish that not having to defoamer can smoothly produce.Defoaming experiment is have also been made herein,
Add minimal amount of silicone defoamer, you can reach extraordinary effect.
S2, mixed material is put into sand mill be ground, add the defoamer of compound gross mass 0.2%, wherein
Grinding temperature is 20-35 DEG C, milling time 2.5-4h.
S3, the size using Rise-2202 fully-automatic laser dynamics analyzer detection particle diameter and distribution；Examination criteria is 2
μm number of particles>90%.
S4, lapping liquid is filtered and allocated obtain product, wherein filter type is as follows：The sand mill was provided with
Filter screen, lapping liquid is filtered by the screen pack；Dispensing mode is as follows：It is water-soluble that xanthans is made in the xanthans
Liquid, then by the lapping liquid after xanthan gum solution supplying filtering.
Final product quality index such as following table produced by the present invention：Wherein low-temperature stability and heat storage stability experiment, every three
The moon is carried out 1 time.
Finished product detection account produced by the present invention is as follows：
As seen from the above table, the present invention has advantages below：
(1) aqueous suspension agent produced by the present invention not only stable performance, good drug efficacy and reliable in quality, has high content and height
Suspensibility advantage；
(2) present invention is simple and easy, and environmental pollution is small, and developing direction and the mankind for meeting environment friendly agricultural novel form are sustainable
The requirement of stable development target.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, although with reference to foregoing reality
Apply example the present invention is described in detail, for those skilled in the art, it still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent substitution to which part technical characteristic.All essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
