Abstract
The present invention discloses a method for preparing a pesticide suspending agent, comprising the steps of mixing and then primarily pulverizing an original solid pesticide and solid auxiliary agents into powder of 150-250 mesh, executing rigid gas flow pulverization and flexible gas flow pulverization to obtain a dust concentrate powder of 5-10 mum, mixing and then shearing the dust concentrate powder, liquid auxiliary agents and water to obtain the pesticide suspending agent. The present invention has the advantages of simple process, convenience in dissemination and popularization, energy consumption reduction of 20-50%, and greatly enhances application performances of suspending agents due to small grain diameter of particles pulverized and homogeneous dispersion.
Description
Technical field
The invention belongs to formulations of pesticide field, be specifically related to a kind of weed killer herbicide, bactericide, agrochemical agricultural chemicals suspension agent formulation manufacture method.
Background technology
Missible oil, pulvis, wetting powder, granule four major types are occupied an leading position on the formulations of pesticide at present, and wherein the missible oil formulation accounts for half of agricultural chemicals total amount.Farm chemical emulsion preparation not only expends a large amount of organic solvents, and serious environment pollution.Therefore, use no or little organic solvent in recent years aborning, the novel form good with Environmental compatibility obtains exploitation as far as possible.At present, the novel form development trend just towards water-based, granular, slowly-releasing, multi-functional, laborsaving, become more meticulous and the direction of high concentrationization develops, some are efficient, safety, economy, labour-saving formulation are risen.
Suspending agent is that domestic and international pesticide industry is generally acknowledged, once is referred to as the novel form of " epoch-making ".Undoubtedly, the exploitation of this novel form, the production and the application of giving the solid pesticide that is insoluble in water and organic solvent have been started vast potential for future development, and have been had very strong competitiveness.Because it has outstanding advantage than missible oil, pulvis, wetting powder, and be studied, production and application units extensively note and pay attention to.Now existing hundreds of suspending agent exploitations are put into production.Its processing technology is not quite similar, and the sand mill of use, colloid mill, ball mill etc. are arranged, but the waterproof pulverization that the method for using both at home and abroad now all is to use, this method need comprise all raw materials that water all carries out waterproof pulverization, energy consumption is very high.
Summary of the invention
The objective of the invention is to overcome the shortcoming in the grinding mode process of waterproof pulverization, propose that a kind of technology is simple, energy consumption is low, be convenient to the dry pulverization process manufacture of the agricultural chemicals suspension agent of penetration and promotion.
Purpose of the present invention can reach by following measure:
A kind of manufacture method of agricultural chemicals suspension agent, the former medicine of agricultural chemicals solid is mixed the back just be ground into 150～250 purpose powder with solid additive, pass through rigidity comminution by gas stream and flexible comminution by gas stream again, obtain female powder of 5～10 μ m, with shearing after female powder, liquid adjuvants and the water mixing, obtain agricultural chemicals suspension agent.
Wherein just pulverize and adopt hammer mill to pulverize, the rigidity comminution by gas stream adopts flat airslide disintegrating mill (as rotating disc type air-flow machine) to pulverize, and flexible comminution by gas stream adopts the fluidized bed type airslide disintegrating mill to pulverize.Shearing mining height speed clipper shears.
The present invention adopts three grades of pulverizing process in pulverizing process, earlier be ground into 150～250 purpose powder through hammer mill, be ground into 600～800 purpose powder through flat airslide disintegrating mill again, after the fluidized bed type airslide disintegrating mill is pulverized, get ultra-fine female powder of 5～10 μ m again.The feeding air pressure of wherein flat airslide disintegrating mill and fluidized bed type airslide disintegrating mill is 0.3～0.9MPa, and the pulverizing air pressure is 0.6～1.5Mpa, and charging rate is 15～130kg/h.
Concrete grammar of the present invention is: former medicine of agricultural chemicals solid and solid additive are mixed, be ground into 150～250 purpose powder through hammer mill, be ground into 600～800 purpose powder through flat airslide disintegrating mill again, after pulverizing, the fluidized bed type airslide disintegrating mill gets female powder of 5～10 μ m again, the feeding air pressure of airslide disintegrating mill is 0.3～0.9Mpa, the best is 0.8Mpa, the pulverizing air pressure is 0.6～1.5Mpa, the best is 1.2Mpa, charging rate is 15～130kg/h, and the best is 45～50kg/h.To shear in the adding high-speed shearing machines such as female powder, liquid adjuvants, water, shear rate is 500～3500 commentaries on classics/min, can obtain even agricultural chemicals suspension agent of the present invention.
The quality of agricultural chemicals suspension agent composition is generally among the present invention: former medicine 2～60%, and dispersant 2～25%, antifreezing agent 0.1～10%, wetting agent 1～15%, thickener 0～5%, defoamer 0～5%, stabilizing agent 0～5%, water complements to 100%.
The former cartridge bag that the present invention selects for use is drawn together various weed killer herbicides, bactericide, agrochemical agricultural chemicals, as atrazine, Imidacloprid, dichloro quinolinic acid, two careless ether, own azoles alcohol etc.
The dispersant that the present invention selects for use comprises lignosulfonates, alkyl sulfate, alkylsulfonate, 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, polyacrylate etc., and preferred dispersing agent is alkylaryl sulfonates, fatty alcohol-polyoxyethylene ether, aliphatic alcohol sodium sulfate, cocoyl sodium sulfonate or 16 carbon fatty alcohol sodium sulphate, polyacrylate.
Be applicable to that defoamer of the present invention comprises organic silicone, eight to ten carbon fatty alcohols, ten to 20 carbocyclic aliphatic alcohol esters or ether etc., preferred defoamer is the organosilicon ketone.
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 be lauryl sodium sulfate, to methoxyl group fatty acyl amido benzene sulfonic acid sodium salt or sodium butylnaphthalenesulfonate.
Thickener of the present invention such as xanthans, gum Arabic, cellulose base compound, starch compound etc.Preferred binding agent is xanthans, aluminium-magnesium silicate.Antifreezing agent such as ethylene glycol, propane diols, glycerine, urea, mineral salt etc.Preferred binding agent is ethylene glycol, propane diols.Stabilizing agent such as acetic acid, hydrochloric acid, sodium hydroxide, potassium hydroxide, triethanolamine etc., preferred stabilizing agent is acetic acid, triethanolamine.
Technology of the present invention is simple, be convenient to penetration and promotion, because of just wherein the solid material of pulverizing, and that the solid material generally only accounts for is whole 8～50%, so energy consumption can save 20～50%, and the pulverized particles particle diameter is little and be uniformly dispersed, and has increased the application performance of suspending agent greatly.
