Abstract
Provided is a synthetic method of cyhalothrin water emulsion. After raw materials are mixed, D-phase emulsification is used for making the water emulsion, and the raw materials comprise, by weight, 2.5%-10% of efficient cyhalothrin, 10%-20% of solvents, 3%-10% of emulgator RED number 102, 0.5%-6% of cosolvent,and the balance deionized water.
Description
Technical field
The present invention relates to a kind of synthetic method of cyhalothrin aqueous emulsion.
Background technology
Emulsion reduces greatly to the toxicity of warm blooded animal, and the poisoning of plant is alleviated greatly, and its active matter content modification scope is large.Aqueous emulsion is compared with microemulsion, because its amount of auxiliary consuming is less, so production cost is well below microemulsion.From preparing pesticide concentration scope, aqueous emulsion can compound concentration up to more than 60%, and microemulsion can only be below 20%; And aqueous emulsion under certain condition can be mixed mutually with other medicament such as suspending agent or liquid fertilizer, as can be compound with aqueous suspension (SC), makes suspension emulsion (SE).
Pyrethroid pesticide is the outer middle larger insecticide of usage amount of Present Domestic, and genus is tagged, stomach toxicity type insecticide insecticidal activity is high, can effectively prevent and treat the multiple lepidoptera pest on cotton, soybean, fruit tree, vegetables, peanut and other crops.Insecticidal spectrum is wide, and active high, drug effect is rapid.Resistance of rainwater washing against after spray medicine, low-residual, to ecological environment security.Some kinds can doublely be controlled mite class.
Along with the development of agricultural chemicals compound probability, pyrethroid pesticide is abundanter now, and nearly twenties kinds, wherein agricultural chrysanthemum ester class just has ten kinds of left and right.But the preparation of pyrethroid pesticide is sold and is only limited to missible oil, wetting powder on market, for other formulations, phoenix feathers and unicorn horns on market.
Summary of the invention
technical problem
In view of this, the technical problem to be solved in the present invention is that the synthetic method of the cyhalothrin aqueous emulsion that a kind of yield is high, production cost is low is provided.
solution
In order to solve the problems of the technologies described above, the invention provides a kind of synthetic method of cyhalothrin aqueous emulsion, after raw material is mixed, make by the emulsification of D phase, described raw material is mixed by following components by weight percentage: gamma cyhalothrin 2.5%～10%, solvent 10%～20%, emulsifier 3%～10%, cosolvent 0.5%～6% and surplus deionized water.
Preferably, described cosolvent is the mixture of n-butanol and propane diols.
Preferably, described solvent is solvent naphtha 180#.
Preferably, described emulsifier is RED102#, agriculture breast 500 or 1101#.
beneficial effect
The invention provides the synthetic method of the cyhalothrin aqueous emulsion that a kind of yield is high, production cost is low.
Embodiment
Embodiment 1
The former powder 2.5% of gamma cyhalothrin; Solvent 180#15%; RED102#8%; Propane diols 5%; Glacial acetic acid 0.05%; Deionized water adds to 100%.Processing method is for utilizing D phase emulsion process, utilize the aqueous emulsion of this method processing may access particle more evenly, the better pesticide emulsion in water of stability.
In 2.5% gamma cyhalothrin aqueous emulsion, use solvent naphtha 180#, its oil phase density levels off to the density of water, can prevent better that analysing or the generation of layering because density variation causes too greatly breast from appearring in aqueous emulsion.
Constant speed stirrer can not provide enough abilities to form required drop, so the sample bleed rate of preparation is all higher before and after heat storage, cold storage.And stator-rotor configuration in high speed dispersion homogenizer can be supplied with higher mechanical energy.
Embodiment 2
Gamma cyhalothrin 10%, solvent naphtha 180#10%, emulsifier 1101#5%, propane diols 5%; Glacial acetic acid 0.1%; Deionized water adds to 100%.
The selected process equipment of high speed shear homogenizer as aqueous emulsion that utilize; Processing method is for utilizing D phase emulsion process, utilize the aqueous emulsion of this method processing may access particle more evenly, the better pesticide emulsion in water of stability.
The test of pesticide effectiveness shows, after control cabbage caterpillar (Pieris rapae L.) medicine, preventive effect is more than 90%, and this medical instrument has good quick-acting and lasting effect.It is compared under equal effective ingredient consumption with the efficient cyhalothrin emulsifiable concentrate that contrasts agricultural chemicals dosage, and preventive effect difference is not remarkable.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
