Abstract
The invention discloses a butene-fipronil aqueous suspending agent and a preparation method thereof, belonging to the technical field of insecticide containing heterocyclic compounds. The butene-fipronil aqueous suspending agent comprises the following raw material ingredients in percentage by mass: 1-40% of butene-fipronil raw pesticide, 1-5% of a wetting and dispersing agent, 0.5-5% of a penetrating agent, 0.1-2% of a thickening agent, 0.5-5% of an anti-freezing agent, 0.1-0.5% of an antifoaming agent, and 43-90% of water. The butene-fipronil aqueous suspending agent disclosed by the invention has the following advantages: the solvent of the butene-fipronil aqueous suspending agent is water instead of an organic solvent in a conventional pesticide missible oil preparation; therefore, production cost is lowered, and pollution is reduced, the butene-fipronil aqueous suspending agent is convenient to use and can be sprayed directly or after being diluted. The butene-fipronil aqueous suspending agent further has the advantage that the average grain diameter of the grains generally is less than 3 microns, thus greatly increasing the suspension rate of the grains in a water medium, and enhancing the absorption of crops for the agent.
Description
Technical field
The present invention relates to a kind of Tintinnid nitrile aqueous suspension agent and preparation method thereof, it belongs to and contains heterocyclic compound insecticide technical field.
Background technology
Present many pesticidal preparations are missible oil; Wherein solvent is an organic solvent; For example: fluorine worm nitrile. phoxim emulsifiable concentrate (patent No. is CN101002568A) has adopted a large amount of organic solvents, like toluene, xylol, methyl alcohol etc., inflammable and explosive, the serious environment pollution of these organic solvents; And people and animals are constituted direct harm, also waste a large amount of non-renewable resources.With an organic solvent not only improve the pesticide producing cost in large quantities, increase heavy financial burden, and also can cause serious waste, give to produce and store and transport and bring many inconvenience packing material to the peasant.Improving constantly of Along with people's quality of life and becoming more and more important of environmental protection, the environment-friendly pesticide preparation will become the main developing direction of agricultural chemicals.
Summary of the invention
In order to solve the problem that exists in the above-mentioned prior art, the object of the invention provides a kind of Tintinnid nitrile aqueous suspension agent and preparation method thereof, under the prerequisite that guarantees drug effect, can reduce effectively surrounding environment is polluted, and also reduces simultaneously and produces and use cost.
The technical scheme that the present invention adopts is: a kind of Tintinnid nitrile aqueous suspension agent, and its characteristics are: the material composition and the mass percent of said composition Tintinnid nitrile aqueous suspension agent are:
Composition quality percentage
A, the former medicine 1-40% of Tintinnid nitrile
B, wetting dispersing agent 1-5%
C, bleeding agent 0.5-5%
D, thickener 0.1-2%
E, antifreezing agent 0.5-5%
F, antifoaming agent 0.1-0.5%
G, water 43-90%
The material composition mass percent sum of said composition Tintinnid nitrile aqueous suspension agent is 100%.
Described wetting dispersing agent is selected from one or more in APES, phenethyl phenol polyethenoxy ether, alkyl phenol formaldehyde resin polyoxyethylene ether, alkylaryl polyoxyethylene poly-oxygen propylene aether, APES sulfosuccinate, aliphatic alcohol polyoxyvinethene phosphate and the NPE phosphate.
Described bleeding agent is selected from the organosilicon bleeding agent.
Described thickener is selected from a kind of or any two kinds of mixtures in gum Arabic, xanthans, methylcellulose, carboxymethyl cellulose, hydroxyethylcellulose, white carbon, bentonite, the aluminium-magnesium silicate.
Described antifoaming agent is selected from a kind of in n-octyl alcohol, the silicone defoaming agent.
Described antifreezing agent is selected from a kind of in ethylene glycol, glycerine, the urea.
The preparation method of described a kind of Tintinnid nitrile aqueous suspension agent comprises the steps:
(1) batching: with wetting dispersing agent, bleeding agent, antifreezing agent, antifoaming agent and water; Put in the mixing kettle according to said formula ratio; Stir 15-25 minute even to mixing of materials, under stirring, put into former medicine of Tintinnid nitrile and thickener then according to said formula ratio, stirred 25-35 minute.
(2) ball milling: above-mentioned material is put into ball mill carry out ball milling, ball milling is to there not being visible bulk particle.
(3) sand milling: the material that ball milling is good is put into sand mill again and is carried out sand milling, makes its particle diameter be no more than 3 microns.
(4) packing: the material that sand milling is good transfers to preparation still, packing after the assay was approved.
Beneficial effect of the present invention is: this Tintinnid nitrile aqueous suspension agent compared with prior art; A large amount of costs of material have been practiced thrift through the change of formulation; Organic solvent in the conventional cream preparation is up to 60-80%; If the price of toluene or xylol is by 9000 yuan of calculating per ton, the solvent of producing 300 tons of cream preparation consumption per year is about ten thousand yuan of 162-216.As Tintinnid nitrile aqueous suspension agent solvent of the present invention is water, and it has replaced the organic solvent in the conventional cream preparation, and cost almost can be ignored, and just can practice thrift ten thousand yuan of 162-216 so over a year, and reduce the pollution to surrounding environment effectively.Being also advantageous in that of Tintinnid nitrile aqueous suspension agent, the average grain diameter of its particle have been improved the suspensibility of particle in water quality greatly generally below 3 microns, have strengthened the absorption of crops to medicament.
