Description
Technical field
The present invention relates to the granular pesticide applying a kind of coalescents to prepare high-load, this high-content particle agent includes：A
Phase component and B phase component, wherein A phase component is 1%-40% agricultural chemicals function sexupara powder；B coordinates and is divided into：1%-10% binding agent,
1%-20% derivant, 0.1%-5% warning coloration, balance of particulate vector.The invention still further relates to above-mentioned high-load pesticide granules
The preparation method of coating and shaping of agent, this preparation method can be produced not by adjusting medicine film layer thickness and the uniformity
With pesticide activity constituent content coating method granule.Its preparation method includes：After first pesticide original medicine being pulverized, with suitable
Mixed method carries out being mixed the function sexupara powder of proper content with coalescents and other auxiliary agents.Use binding sizing agent and load again
Body carries out being mixed and made into coating method granule.
Technical background
By the method for coating film forming by the active component uniform adhesion of agricultural chemical insecticide at a diameter of 12-50 mesh (0.27-
On particulate vector 1.4mm), form coating method granule.Coating method granule has following important feature：
1) form with hidden dispenser, utilizes interior suction, conduction function that plant has by medicine to be transmitted in plant, reaches anti-
The functions such as disease is cured the disease, insect killing and preventing and chemical weed control.
2) coating method granule can be according to the cycle of plant growth, by adjusting physical volume or the active component content of dispenser
Height, the efficacy of a drug needing in plant whole growth period is persistently provided, a dispenser can reduce the disease in Crop growing stage
Pests Damage degree, is greatly reduced medication quantity and the spraying times in planting cycle, be pesticide reduction medication can not or
The preparation formulation lacking.
3) medicine is directed to target pest and disease damage, and natural enemy not damage to crops, therefore extremely safe to natural enemy, it is all agricultural chemicals systems
One of formulation can preserved the ecological environment in agent.
Make, by coating membrane formation process, the history that granular pesticide has had decades in China, but film forming application technology develops
Very slow, with adhesive, active ingredient is coated film forming, there is following common technical problems in this technology：
1) diameter of carrier granular determines the specific surface area of carrier, and can active ingredient be uniformly distributed in the table of limited carrier
Face.The uniformity of medicine film and thickness determine granule active constituent content, for a long time, in addition to the formulation of low content,
The control medicine film uniformity is in space state with the technical elements of thickness；
2) differential tension that adjacent interfaces exists between granule makes during film forming due to solid-liquid, it may appear that flowing exhibition
Cloth and Levelling defects, cause active ingredient can not film forming or can not completely film forming and become free state, and affect the conjunction of product
Lattice rate.Meanwhile, it is coated that film forming is insecure to be caused medicine film to come off affecting the safety normally playing and jeopardizing user of the efficacy of a drug.
3) the excessive fluid binder of application is by medicine coated carrier, but causes simultaneously and bond between adjacent particle, gather
Group.In order to avoid such phenomenon, to reduce the ratio of slurry to prevent clay phenomenon.But, the insufficient amount of feelings of slurry
Under condition, medicine film cannot be formed, and its result is coming off and forming toxic dust of active ingredient.
4) in the case of lacking medicine film levelling film forming and thicken technology.The active ingredient number of cladding is limited, therefore, once
The low content granule less than 5% for the active ingredient can only be made in the case of coating.Make and need higher than 5% high-content particle agent
Coating that will be above twice, difficulty of processing is big, expends resource many, and production cost is high.
5) with hidden insecticide-applying way, or long holding effect quick-acting with the change of the content control efficacy of a drug by different in kind consumptions plays,
The comprehensive granular pesticide formulation solving phytopathy, worm, prevention and control of weeds and safe medication.Seriously pull because of the existence of the problems referred to above
Elbow its normal use.

It according to efficacy of a drug release principle, is coated on rate of release and the carrier of the active constituents of medicine on granule carrier surface
Specific surface area is relevant, and efficacy of a drug rate of release is long-pending to specific grain surface to be directly proportional, more big more beneficially medicine the release of specific surface area.
Under conditions of specific surface area is constant, by improving the active component content of carrier carrying, can have under identical release conditions
Effect adjusts the deenergized period of the efficacy of a drug, it is thus achieved that the longer lasting period.
The lasting period effect demonstration of the different quantity of goods produced of identical active component：
Experimental principle：Cholinesterase can be catalyzed indophenols acetic acid esters (red) and be hydrolyzed to acetic acid and indophenols (blue), amino first
Whether acid esters agricultural chemicals has inhibitory action to cholinesterase, makes catalysis, hydrolysis, colourshifting process change, thus judge in sample
With the presence of carbamate pesticide.(GB5009.199-2003)

0.01%-3% warning coloration purple or any one of acid black or other direct dyess for alkalescence
1%-10% derivant sucrose
Balance of 12-50 mesh silica river sand or fragmented rock particle are any.
6. the preparation method of the granule according to claim 1 to 5 any one, is characterized in that, comprises the following steps：
The first step prepares the function sexupara powder of A phase component：First former for active component medicine is carried out mechanical crushing or air-flow crushing, obtain
Particle diameter is the 325 former medicine fine powders of purpose.Take active component former medicine fine powder 1%-30% more by weight；Coalescents 0.5%-
10%；Water reducer 0.5%-10%；Dispersant 0.1%-5%；Wetting agent 0.1%-5%, is placed in Agravicmixer and loses
Heavily mix, obtain function sexupara powder, standby；
Second step prepares the bonding slurry of B：Take 1%-10% binding agent according to weight ratio；1%-10% derivant；0.01%-
3% warning coloration is placed in the container with stirring and heating, stirs to homogeneously at 90 DEG C, standby；
3rd step prepares finished product：Taking 70%-90% particle diameter by weight is that 12-50 mesh carrier granular is placed in mixing seed-coating machine,
Add 3%-15% binding sizing agent in the state of stirring, continue stirring to binding sizing agent uniform wet and be distributed in particle surface；Again
Add 1%-30% function sexupara powder, until female powder forms medicine film at particle surface, obtain the wet feed of finished product.Again wet feed is placed in
It is dried in roll-drying machine, obtain coating method granule finished product.
