Abstract
The invention discloses an acetamiprid water dispersible granule, which comprises the compositions by weight portion of: 5 to 80 percent of acetamiprid, 2 to 25 percent of dispersant, 2 to 20 percent of disintegrant, 1 to 15 percent of wetting agent, 0.1 to 10 percent of binder and others filler which is added for up to 100 percent. The acetamiprid water dispersible granule of the invention has the advantages of stable physical and chemical properties, not easy to be decomposed and degenerated. The acetamiprid water dispersible granule is not require to use organic solvents, and has no floating powder, no inflaming and exploding possibility, thus saving petroleum resources and reducing environmental pollution, being safe to operators and environment in producing and using; the preparation with high content can be processed according to the needs, and also has the advantages of saving cost of packaging, storing and transporting.
Description
Technical field
The invention belongs to formulations of pesticide field, be specifically related to a kind of acetamiprid water dispersible granules and preparation method.
Background technology
Acetamiprid (acetamiprid) belongs to the bionical insecticide of anabasine, acetyl courage receptors bind in this insecticide and the insect bodies makes the insect exaltation, whole body spasm, paralysis and dead, every mu only needs with effective ingredient 0.5 gram is the harm of controlled field insect, be one of minimum insecticide of present consumption, moderate toxicity.This insecticide is also effective to the insect that pyrethroid, organic phosphates, carbamates produce resistance.Be applicable to the various pests of crops such as control cotton, paddy rice, fruit tree, vegetables, upland grain, tea tree, tobacco, especially lepidoptera pest, homoptera pest, coleopteran pest, thrips order insect all had special efficacy.Common formulations is 3% missible oil at present, that is to say in 1 ton of 3% acetamiprid EC, to have only 30 kilograms of effective ingredients, and all the other 970 kilograms is organic solvent and auxiliary agent.From above situation as can be seen, for the insecticide that makes super-high-efficient can evenly distribute in the field, allow all insects in field can both touch medicament, method originally is when being processed into cream preparation, content is reduced as far as possible, under the effect of a large amount of organic solvents, the effective ingredient of trace is infiltrated in the insect bodies, reach the purpose of kill pests.For this reason, not only consume a large amount of petroleum resources, increased a large amount of packings, stored cost and cost of transportation, more seriously caused environmental pollution, influenced people's healthy and social lasting, harmonious development.The scope of application and the service life of the bionical insecticide Acetamiprid of super-high-efficient have been limited simultaneously.
Summary of the invention
The objective of the invention is to overcome acetamiprid EC and need consume a large amount of organic solvents and environment is caused the defective of severe contamination, develop a kind of environment-friendly highly efficient, broad spectrum pesticide that contains Acetamiprid.
Purpose of the present invention can reach by following measure:
A kind of acetamiprid water dispersible granules, its quality group becomes: Acetamiprid 5～80%, dispersant 2～25%, disintegrant 2～20%, wetting agent 1～15%, binding agent 0.1～10%, filler complements to 100%.
The dispersant that the present invention selects for use comprises lignosulfonates, alkyl sulfate, alkylsulfonate, naphthalene sulfonic acid-formaldehyde condensation product, the styryl phenol polyethenoxy ether, alkylaryl polyoxyethylene polyoxy third rare ether, alkylaryl methyl ether resin APEO, Alpha-Methyl Bian Ji APEO, the alkyl sulfonic acid salt anionic surfactant, phosphate type anion surfactant etc., preferred dispersing agent is an alkylaryl sulfonates, fatty alcohol-polyoxyethylene ether, aliphatic alcohol sodium sulfate, cocoyl sodium sulfonate or 16 carbon fatty alcohol sodium sulphate, most preferably sodium methylene bis-naphthalene sulfonates.
Be applicable to that disintegrant of the present invention comprises starch, mineral salt, sodium carboxymethyl starch, polyvidone etc., preferred disintegrant is sodium carboxymethyl starch or polyvidone, most preferably sodium carboxymethyl starch.
Be applicable to that wetting agent of the present invention has alkyl sulfate, naphthalene sulfonic acid-formaldehyde condensation product, styryl phenol polyethenoxy ether, alkylaryl polyoxyethylene polyoxy third rare ether, alkylaryl methyl ether resin APEO, Alpha-Methyl Bian Ji APEO, alkyl sulfonic acid salt anionic surfactant, phosphate type anion surfactant etc., preferred humectants is lauryl sodium sulfate, to methoxyl group fatty acyl amido benzene sulfonic acid sodium salt or sodium butylnaphthalenesulfonate, most preferably be methoxyl group fatty acyl amido benzene sulfonic acid sodium salt.
Binding agent of the present invention such as xanthans, gum Arabic, cellulose base compound, starch compound etc.Preferred binding agent is sodium carboxymethylcellulose, Ac-Di-Sol, polyvinyl alcohol or gum Arabic; Most preferably sodium carboxymethylcellulose or Ac-Di-Sol.
Filler of the present invention such as bentonite, white carbon, mineral salt etc., preferred filler is mineral salt such as sodium sulphate, urea, ammonium sulfate or sodium chloride, most preferably is anhydrous sodium sulfate.
Water dispersible granules of the present invention adopts the processing technology of mixing-pulverizing-mixing-granulation again-screening.Concrete preparation method carries out coarse crushing with Acetamiprid, dispersant, disintegrant, wetting agent, binding agent and filler earlier, mixes then, carry out ultra-fine grinding again, obtain the above superfine powder of particle diameter 1000 orders after, carry out granulation again, sieve with vibratory sieve at last, obtain finished product.
Be compared with the prior art, advantage of the present invention and good effect are:
1, neither need to use organic solvent, do not have the dust drift again, can not burn, can not explode, can save petroleum resources and alleviate environmental pollution, produce and use in to operator and Environmental security.
2, the preparation of high-load be can be processed into as required, packing, storage, cost of transportation saved.
3, physics, stable chemical performance are difficult for decomposing rotten.
4, finished product is a granular solids, good fluidity, and not sticking wall after toppling over can not remain in and form secondary pollution in the packing container.
5, available papery packing is convenient to reclaim and is destroyed or natural degradation.
6, medicine grain diameter is superfine, helps target and fully absorbs and play a role, and can reduce the effective ingredient consumption, improves effect.
7, meaning of the present invention is not only to research and develop out environment-friendly highly efficient, broad spectrum pesticide; but can be extended on other super-high-efficient insecticide, bactericide, weed killer herbicide and the plant growth regulator by the present invention; improve the level of processing of China's formulations of pesticide; to improve the availability of pesticide active ingredient; reduce the use of auxiliary agent, organic solvent, auxiliary material; reduce agricultural chemicals to greatest extent to negative effect that environmental protection brought; promote China's agricultural chemicals competitiveness in the international market simultaneously, for country strives for foreign exchange.
