Abstract
The invention relates to a diniconazole suspending agent formula and a preparation method thereof, which are suitable for a technique for producing pesticide preparations and belong to the technical field of chemical engineering. Because wettable powder can generate dust pollution easily during processing and using and the suspension percentage of the wettable powder is lower than that of a suspending agent, a product can generate drug misadventures easily. A diniconazole suspending agent is prepared from the substances such as a diniconazole material medicament, a wetting agent, a dispersing agent, a thickening agent, a defoaming agent, an antifreezing agent, an antiseptic agent and the like according to certain percentages by weight and a specific preparation method. The diniconazole suspending agent has the advantages that the diniconazole suspending agent can be evenly mixed with and dispersed in water in any ratio, has good fluidity, is not influenced by the water quality and the water temperature, is convenient to use, cannot pollute the environment easily, and can be used for spraying directly or after being diluted.
Description
Technical field
The present invention relates to a kind of pesticidal preparations prescription and preparation method thereof, be applicable to the pesticidal preparations manufacturing technology, belong to chemical technology field.
Background technology
Alkene azoles alcohol belongs to triazole bactericidal agent, suppresses 14 α-demethylation effect in the ergosterol biosynthesis of fungi, causes that ergosterol lacks, and causes fungal cell membrane undesired, final fungi death.Alkene azoles alcohol mainly is market-oriented with 12.5% wetting powder at home.Because wetting powder is easy to generate dust pollution when processing and use, the suspensibility of wetting powder is lower than suspending agent in addition, and product easily produces poisoning.Therefore, along with the enhancing of people's environmental consciousness, and the needs of modern agricultural development, exploitation is safely, the pesticides new formulation meaning is very important efficiently.Because suspending agent is processed with wet method, does not produce dust, be that water replaces organic solvent, be fit to environmental requirement, product granularity is thinner than wetting powder in addition, and active ingredient is loose evenly, suspensibility height, drug effect are present more satisfactory environmental protection novel forms than wetting powder height.
Summary of the invention
In order to solve the problem that existing wetting powder dust works the mischief to people, livestock and environment easily, the invention provides a kind of diniconazole suspending agent formula and preparation method thereof.
Technical scheme of the present invention is achieved in that it is made up of the former medicine of alkene azoles alcohol, wetting agent, dispersant, thickener, defoamer, antifreezing agent, preservative, wherein the percentage by weight of each component is: the former medicine 5～85% of alkene azoles alcohol, wetting agent 0.5～10%, dispersant 0.5～10%, thickener 0.1～5%, defoamer 0.1～5%, antifreezing agent 1～10%, preservative 0.1～10%, surplus is a water.
Preparation method of the present invention is with the former medicine of a certain amount of alkene azoles alcohol, wetting agent, dispersant, thickener, defoamer, antifreezing agent, preservative and water, is 1～5 μ m with the sand mill waterproof pulverization that repeatedly circulates to grain fineness, carries out homogenize, thickening, froth breaking with homogenizer again and is prepared from.
Wetting agent is selected from one or more in aliphatic alcohol sulfate, a-alkene sulfonate, dialkyl group succinate sulfonate sodium, fatty alcohol, alkylphenol polyoxyethylene succinic acid half ester sulfonate, fatty acid amide N methyl taurine sodium salt, alkylphenol polyoxyethylene sulphate, Negel, alkylphenol polyoxyethylene, the fatty alcohol-polyoxyethylene ether in the prescription; Dispersant is selected from one or more in fatty alcohol ether phosphate, nonyl phenol ether phosphate, triphen ethyl-phenol APEO, the phosphate triethanolamine salt;
In dispersant preferred fat alcohol sulfate, fatty acid amide N methyl taurine sodium salt, fatty alcohol, the alkylphenol polyoxyethylene succinic acid half ester sulfonate one or more; In dispersant preferred fat alcohol ether phosphate, nonyl phenol ether phosphate, the phosphate triethanolamine salt one or more.The suspending agent that adopts above-mentioned wetting agent and dispersant to form has increase dispersed and mobile;
Thickener is selected from one or more in gum Arabic, xanthan gum, methylcellulose, carboxymethyl cellulose, hydroxyethylcellulose, PAA, polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl acetate, gaseous state silica, the Magnesiumaluminumsilicate; Defoamer is selected from fatty alcohol, C10～20 representative examples of saturated aliphatic carboxylic and the ester class thereof of organosilicon ketone, C8～10, in the ester one ether type compound one or more: antifreezing agent is selected from one or more in ethylene glycol, propane diols, glycerine, diethylene glycol (DEG), triethylene glycol, polyethylene glycol, monoethylin diglycol, methyl trimethylene diglycol, urea, ammonium sulfate, the citric acid: preservative is selected from formaldehyde or paraformaldehyde;
Advantage of the present invention is evenly to mix dispersion with the water arbitrary proportion, and good fluidity is not influenced by water quality, water temperature, and is easy to use, is difficult for contaminated environment, can directly or after the dilution spray.
