Abstract
The invention discloses a dichlorbenzuron suspending agent and a preparation method thereof. The dichlorbenzuron suspending agent comprises the following raw materials by mass percent: 3-8% of urea, 0.3-0.8% of carboxymethyl cellulose, 0.5-1% of aluminum magnesium silicate, 3-5% of an emulsifier 6419, 3-5% of an emulsifier 7106, 0.5-1% of benzoic acid, 20-25% of a dichlorbenzuron active compound and the balance of deionized water. The dichlorbenzuron suspending agent and the preparation method, provided by the invention, are efficient, low in toxicity, free of pollution, safe to environment, human beings and poultry and low in probability of producing drug resistance; urea is used for substituting ethylene glycol, so that the production cost is reduced and the environment pollution is reduced too; aluminum magnesium silicate and carboxymethyl cellulose are used as thickeners to substitute xanthan gum used in the current production, so that the work efficiency is increased, and the requirement for realizing continuous large-scale production is satisfied.
Description
Technical field
The present invention relates to technical field of pesticide, be specifically related to a kind of Chlorbenzuron deflocculant and preparation method thereof.
Background technology
Agricultural chemicals can be used for kill insects, fungi and other damages to crops growth biology.The agricultural chemicals used the earliest has dichlorodiphenyl trichloroethane, hexachlorcyclohexane etc., and they can eliminate destructive insects in a large number.But their good stability, can long-term existence in the environment, and constantly accumulates in animals and plants and human body, is eliminated for this reason.Use organophosphorous pesticide instead afterwards, as dichlorvos etc., substitute initial agricultural chemicals.But they contain P elements, easily cause aquatic organism eutrophication.
Suspending agent is a kind of novel form of pesticide processing.It is pesticide original medicine and carrier and dispersant and water composition, and the thickness utilizing wet method to carry out ultramicro grinding can flow, drug effect high low without dust, cost.And have the advantage of wetting powder and missible oil concurrently, can be readily wetted by water, after thin up, suspension is good.Suspending agent has the following advantages: (1) without dust harzard, to operator and Environmental security; (2) take water as dispersion medium, the inflammable and drug injury problem do not produced by organic solvent; (3) compared with wetting powder, the former medicine selecting different-grain diameter is allowed, to make the biological effect of preparation and physical stability reach best; (4) liquid suspension spreads well in water, directly can make spray liquid and use; (5) than great, packaging volume is little.(6) dispersiveness of suspending agent and plate-out ability all relatively good, suspensibility is high, and the ability sticking to plant corpus surface is stronger, resistance of rainwater washing against, and thus comparatively wetting powder is significantly and also more lasting for drug effect.(7) have that particle is little, active surface is large, penetration is strong, drug effect high low without dust, cost when making up a prescription.And have the advantage of wetting powder and missible oil concurrently, can be readily wetted by water, after thin up, suspension is good.
D ichlorbenzuron is a kind of insect growth regulator, IGR, belongs to specificity insecticide.After pests or contact medicament, suppress epidermis chitinous synthesis, larva can not normally be casted off a skin and dead.Mainly stomach poison function, also has certain action of contace poison, but without interior absorption.Have special efficacy to Lepidoptera and Diptera larvae, do not kill adult, but adult can be made sterile, ovum can not normal incubation.But current d ichlorbenzuron toxicity is comparatively large, and use procedure is comparatively complicated, have impact on promoting the use of of d ichlorbenzuron.
Summary of the invention
The invention provides a kind of Chlorbenzuron deflocculant and preparation method thereof, the comparatively large and troublesome problem of use with the toxicity solving prior art existence.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Chlorbenzuron deflocculant, raw material comprises urea, carboxymethyl cellulose, aluminium-magnesium silicate, emulsifier 6419, emulsifier 7106, benzoic acid, benzoylphenyl urea original medicine and deionized water, and wherein each constituent mass content is: urea 3% ~ 8%; Carboxymethyl cellulose 0.3% ~ 0.8%; Aluminium-magnesium silicate 0.5% ~ 1%; Emulsifier 64193% ~ 5%; Emulsifier 71063% ~ 5%; Benzoic acid 0.5% ~ 1%; Benzoylphenyl urea original medicine 20% ~ 25%, surplus is deionized water.
The preparation method of above-mentioned Chlorbenzuron deflocculant, urea is added in deionized water and dissolves, add carboxymethyl cellulose and aluminium-magnesium silicate again and stir, dropping into emulsifier 6419, emulsifier 7106 and benzoic acid after stirring, then drop into benzoylphenyl urea original medicine, finally add appropriate amount of deionized water again, carry out emulsification, after emulsification is qualified, proceed to sand milling, after sand milling granularity reaches standard, carry out filling.
The invention provides a kind of efficient, low toxicity, pollution-free, to Chlorbenzuron deflocculant that environment, people, animal safety and insect not easily develop immunity to drugs and preparation method thereof, urea is used to substitute ethylene glycol, reduce production cost, reduce environmental pollution, use aluminium-magnesium silicate and carboxymethyl cellulose to substitute the xanthans used in production at present as thickener, improve work efficiency, reach the demand realizing serialization large-scale production.
