Abstract
The invention discloses an emamectin benzoate suspending agent and a preparation method thereof. The emamectin benzoate suspending agent comprises the following components by weight percent: 0.2-5 percent of emamectin benzoate, 1-10 percent of wetting dispersant, 2-10 percent of antifreeze agent, 1-6 percent of stabilizing agent, 1-5 percent of defoamer, 0.1-1 percent of thickening agent, 0.1-1 percent of preservative and the balance of water. In the emamectin benzoate suspending agent, an anion active agent is added, thereby the problems of grinding and livering of the emamectin benzoate are solved. Organic solvent harmful to the human and the environment is not adopted in the invention, thereby reducing pollution of the organic solvent to the environment; besides, the adopted dosage form has lower cost, thereby effectively reducing the solvent cost, the package cost and the transportation expense.
Description
Technical field
What the present invention relates to is a kind of emamectin benzoate suspending agent and preparation method thereof.
Background technology
Emamectin-benzoate (being called for short first dimension salt), trade name procloim (banleptm).It is a kind of super-high-efficient green pesticide.Emamectin-benzoate is to be got through chemosynthesis by Avermectin, and the Avermectin series of products are in medicine, agricultural chemicals, field of veterinary extensive use, and being described as is medical revolution again after penicillin.And from Avermectin B1a, through the synthetic first dimension salt of chemical modification and parent Avermectin mutually specific activity improved 10-1000 times, the characteristics that have super-high-efficient, wide spectrum, closely nontoxic, noresidue, do not develop immunity to drugs are assert that in the industry will replace other insecticides becomes 21 century insecticide leading products.The present industrially developed country in the world of emamectin benzoate insecticidal agent has been widely used in the control of grain, economic crops and vegetable-crop pest-insect.Affirm (Merck Co.) is to make paralysis, food refusal, slow or motionless rapidly in the insect several hours by suppressing the intranueral aminobutyric acid transmission of pest movements, and dead in 24-28 hour, is environment friendly agricultural the most efficiently at present.The mode of action of Affirm (Merck Co.) is the main action of contace poison that has concurrently with the stomach toxicity.The a lot of insects of first dimension salt pair have the incomparable activity of other agricultural chemicals, especially to Lepidoptera, diptera, thrips class super-high-efficient.
But first dimension salt pref is still based on missible oil at present, and about 80% (weight ratio) is toluene, dimethylbenzene, methyl alcohol etc. have harm to the mankind and environment organic solvent in the preparation.Used solvent has not only increased the expense of the preparation cost of raw material and packaging material and transportation in the cream preparation, and environment is polluted, so the exploitation of novel environment friendly preparation is the inexorable trend that replaces cream preparation.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of environmental protection, emamectin benzoate suspending agent that cost is low are provided.
Another object of the present invention provides the preparation method of above-mentioned emamectin benzoate suspending agent.
To achieve these goals, the present invention adopts following technical scheme:
A kind of emamectin benzoate suspending agent, form by following component and percentage by weight: emamectin-benzoate 0.2～5%, wetting dispersing agent 1～10%, antifreezing agent 2-10%, stabilizing agent 1-6%, defoamer 1-5%, thickener 0.1-1%, preservative 0.1-1%, surplus is a water.
In above-mentioned emamectin benzoate suspending agent, described wetting dispersing agent is preferably one or more mixing in sodium lignin sulfonate, naphthalene sulfonate, lignosulfonates, fatty alcohol-polyoxyethylene ether, phenethyl phenol polyethenoxy sodium sulphate, alkylphenol-polyethenoxy phosphoric acid fat, polymerization of carboxylic acid salt, the calcium dodecyl benzene sulfonate.
In above-mentioned emamectin benzoate suspending agent, described antifreezing agent is preferably one or more mixing in ethylene glycol, propane diols, urea, the glycerine.
In above-mentioned emamectin benzoate suspending agent, described stabilizing agent is one or more mixing among BHT (2.6-BHT), BHA (butylated hydroxy anisole), the TBHQ (ditert-butylhydro quinone).
In above-mentioned emamectin benzoate suspending agent, described defoamer is preferably organosilicon ketone, C8-C10 fatty alcohol or polyethers defoamer etc.
In above-mentioned emamectin benzoate suspending agent, described thickener is preferably one or more mixing in gum Arabic, xanthans, carboxymethyl cellulose, bentonite, the Magnesiumaluminumsilicate.
In above-mentioned emamectin benzoate suspending agent, described preservative is preferably paraformaldehyde, isothiazolinone or Sodium Benzoate.
The preparation method of above-mentioned emamectin benzoate suspending agent comprises the steps: earlier emamectin-benzoate, wetting dispersing agent, antifreezing agent, stabilizing agent, defoamer to be deployed into mother liquor, through the sand mill wet grinding to particle diameter 3-5nm; Then thickener and preservative are mixed into the thickener mother liquor in proportion, two kinds of mother liquor mixing preparations become emamectin benzoate suspending agent.
Compared with prior art, the present invention has following beneficial effect: emamectin benzoate suspending agent of the present invention has added anion surfactant, has solved the problem of first dimension salt grinding livering; Not adopting has the organic solvent of harm to human and environment, thereby has reduced the pollution of organic solvent to ecotope; And the formulation cost that it adopts is lower, effectively reduces solvent cost, packing cost and freight.
