Abstract
An aqueous emulsion of abamectin is proportionally prepared from abamectin, solvent, emulsifier, thickening agent, anti-freezing agent, defoaming agent and water through preparing oil phase, preparing water phase and mixing while shearing.
Description
Technical field
The present invention relates to a kind of agricultural chemicals and preparation method thereof, relate in particular to a kind of abamectin aqueous emulsion of preventing and treating crop pests such as paddy rice rice leaf roller, striped rice borer, paddy stem borer and preparation method thereof.
Background technology
Great changes have taken place in global in recent years agricultural chemicals policy, particularly developed country is very strict to the use restriction of high poison, persistent pesticide, particularly played the whole nation on January 1st, 2007 and forbid that high-toxic pesticide is after using on the agricultural, with increasing, and high malicious type pesticide species will unfeelingly be eliminated under the effect of forbidding order to the demand of the environmental protection type agricultural chemical of efficient, low toxicity, low-residual in the domestic market.Limiting the use of and further forbid the trend that high-toxic pesticide is social development, also is the needs of realizing agricultural sustainable development.At present, China's high-toxic pesticide occupies quite great proportion, accounts for 70%, and the western developed country situation is then opposite, only accounts for about 30%.
Data show, when totally supply exceed demand, low toxicity high-efficiency environment friendly class agricultural chemicals was in the tangible propagation process at agricultural chemicals, therefore, can estimate, and along with the increasing of governability dynamics, this of high-toxic pesticide and environment-protection pesticide disappears those long relations will be more obvious.
Along with improving constantly of people's living standard; people are to the raising of environmental protection consciousness; and the Chinese government is to the attention of ecotope, on the domestic and international market to be fit to controlling crop diseases and insect pests and nuisanceless production needs efficiently, the demand of low toxicity, low-residual, free of contamination environment protection biological agricultural chemicals and chemical pesticide is increasing.And the low toxicity efficient and environment-friendly type agricultural chemicals market demand is supplied less greatly in the market.
For a long time, the pesticide original medicine of every liquid state and the solid-state former medicine of sizable solvability is arranged in organic solvent, no matter be insecticide, miticide, or bactericide or weed killer herbicide etc., all be that the form of making missible oil is used mostly, emulsifiable concentrates for agricultural chemicals is the important formulation of pesticidal preparations always, but owing to contain a large amount of inflammable organic solvents in the missible oil, strict to aspects such as production, storing and uses, as poor management, intoxicating phenomenon takes place or produces poisoning in misoperation easily.Particularly in long-term use, a large amount of organic solvents evaporate in the atmosphere, and environment has been caused serious pollution, and all these problems have caused people's extensive concern.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of safe in utilization, the feature of environmental protection good, lower-cost abamectin aqueous emulsion and preparation method thereof.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of abamectin aqueous emulsion is characterized in that, it is raw material that this aqueous emulsion adopts the material of following component and weight content:
Avermectin 0.5%～10%,
Solvent 1%～10%,
Emulsifier 1～10%,
Thickener 0.1%～5%,
Antifreezing agent 0.5%～5%,
Defoamer 0.1%～1%,
Moisturizing to 100%.
Described solvent is selected from one or both the mixture in dimethylbenzene, the toluene.
Described emulsifier is selected from the EO-PO block copolymer.
Described EO-PO block copolymer is selected from one or more the mixture in polyoxyethylene alkylphenol, polyoxyethylene alkaryl phenol, polyoxyethylene fatty alcohol, the sorbitol ester.
Described thickener is selected from polyvinyl alcohol or xanthans.
Described antifreezing agent is selected from one or both the mixture in ethylene glycol, the propane diols.
Described defoamer is selected from organosilicon.
A kind of preparation method of above-mentioned abamectin aqueous emulsion is characterized in that, this method comprises following processing step:
(1) makes oil phase
Avermectin 0.5～10 weight % adds with solvent 1～10 weight % and is in the same place, and makes Avermectin be dissolved in fully in the solvent, becomes even oil phase;
(2) make water
Emulsifier 1～10 weight %, thickener 0.1～5 weight %, antifreezing agent 0.5～5 weight %, defoamer 0.1～1 weight % and moisturizing to 100 weight % be added in be mixed together, become the homogeneous water;
(3) shear
Under high-speed stirred, water is added oil phase, form finely disseminated aqueous emulsion.
Described speed of agitator is 1000～20000 rev/mins, and mixing time is 3～60 minutes.
Abamectin aqueous emulsion of the present invention is the functional novel form initiative agricultural chemicals that Shanghai Nongle Biological Product Co., Ltd. develops, because abamectin aqueous emulsion does not contain poisonous inflammable benzene class equal solvent, there is not the danger of catching fire, no unpleasant poisonous smell, little to eye irritation, reduced pollution, improved safety greatly production, storing and user to environment.On the other hand, abamectin aqueous emulsion is a matrix with cheap water, greatly reduces to use farming originally.Therefore form after the industrialization, not only economic benefit is obvious, and helps promoting the development of high-new environment friendly agricultural technology, to promoting environmental protection, has obvious social, is the Research on Sustainable Development direction.
