Abstract
The invention discloses a diflubenzuron suspending agent and a preparation method thereof. The diflubenzuron suspending agent comprises the following raw materials by mass: 3%-8% of urea, 0.3%-0.8% of carboxymethyl cellulose, 0.5%-1% of aluminium-magnesium silicate, 3%-5% of an emulsifier 6419, 3%-5% of an emulsifier 7106, 0.5%-1% of benzoic acid, 5%-25% of diflubenzuron raw material drugs and the balance of deionized water. The diflubenzuron suspending agent which is efficient, low-toxic, pollution-free, and harmless to the environment, people and livestock and the preparation method for the diflubenzuron suspending agent are provided by the invention, pests do not generate resistance easily to the diflubenzuron suspending agent, the urea is used to replace ethanediol, so that the production cost is reduced, the environmental pollution is reduced, the working efficiency is improved as the aluminium-magnesium silicate and carboxymethyl cellulose are used as a thickening agent to replace xanthan gum used in production at present, and the demand of realizing continuous large-scale production is met.
Description
Technical field
The present invention relates to technical field of pesticide, be specifically related to a kind of diflubenzuron suspension 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.
Diflubenzuron is benzoxy phenyl ureas insecticide, and sterling is white crystals, and former powder is that white is to yellow crystalline powder.Water insoluble.Be insoluble in most of organic solvent.More stable to light, heat, meet alkali easily decompose, stable in acid and neutral medium, have larger toxicity to shell-fish and silkworm, to other biological safety in people and animals and environment, belong to low toxicity public nuisance-free agricultural chemicals.
Summary of the invention
The invention provides a kind of diflubenzuron suspension 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 diflubenzuron suspension, raw material comprises urea, carboxymethyl cellulose, aluminium-magnesium silicate, emulsifier 6419, emulsifier 7106, benzoic acid, the former medicine of diflubenzuron 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%; The former medicine 5% ~ 25% of diflubenzuron, surplus is deionized water.
The preparation method of above-mentioned diflubenzuron suspension, urea is added in deionized water and dissolves, add carboxymethyl cellulose and aluminium-magnesium silicate again and stir, after stirring, dropping into emulsifier 6419, emulsifier 7106 and benzoic acid, then dropping into the former medicine of diflubenzuron, 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 diflubenzuron suspension 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.
