Abstract
The invention discloses 80 percent phosethyl-aluminum water dispersible granules. The granules consist of the following components in percentage by weight: 85 to 87 percent of 95 percent phosethyl-aluminum raw drug, 2 to 5 percent of 50 percent alkyl glycoside, 2 to 5 percent of dodecyl dimethyl betaine, 1 to 5 percent of binder gum Arabic, and 5 to 10 percent of filler ammonium sulfate or urea. The preparation method comprises the following steps: uniformly mixing the raw materials, crushing, mixing with water, granulating, and drying to obtain the 80 percent phosethyl-aluminum water dispersible granules. The 80 percent phosethyl-aluminum water dispersible granules have long pesticide effect time and few application times to crops, a fertilizer is applied to the crops while insects and diseases of crops are prevented and controlled, and the crops can absorb nutrition to facilitate growth.
Description
Technical field
The present invention relates to a kind of phosethyl-Al water-dispersible granules (WGD) and preparation method thereof.
Background technology
Phosethyl-Al, common name: fosetyl aluminium, chemical name: three (O-ethylphosphonic acid) aluminium, molecular weight: 354, the former medicine of triethylphosphine aluminium is white powder, colourless, tasteless.Phosethyl-Al is good novel organophosphorus fungicide, has the characteristic of efficient, wide spectrum, safety, mainly prevents and treats the economic crops such as fruit tree, vegetables by downy mildew, the caused disease of phytophthora.Phosethyl-Al bactericide is developed the earliest by French Luo Na-Rhone-Poulenc, in China's production history, grows and has the former medicine of numerous manufacturer production phosethyl-Als, and more than existing former medicine yearly productive capacity reaches ton, it more than 80% is processed into formulation products.But formulation products formulation is single, take 80% phosethyl-Al wetting powder (WP), 90% phosethyl-Al soluble powder (SP) as main.Because the former medical instrument of phosethyl-Al has the easy moisture absorption, density little, all bring certain pollution in production and processing, packed and transported, dispenser use procedure personnel and environment, the long term storage product rotten quality problems that cause of can luming produce.
Water-dispersible granules (WGD) is the novel form of a kind of green, environmental protection.The physical and chemical performance of water-dispersible granules is stable, good product mobility, relative density compared with large, volume is little, the fine solution wetting powder of environmentally friendly energy and soluble powder weak point, give the production and processing of product, packing, the overall process that stores, transports, uses are brought very large economic benefit and social benefit.
Therefore the exploitation of phosethyl-Al water-dispersible granules has wide market prospects and good economic benefit, is deeply subject to the welcome of users at home and abroad.
Summary of the invention
One of object of the present invention is to provide a kind of phosethyl-Al water-dispersible granules.
Two of the object of the invention is to provide the preparation method of above-mentioned a kind of phosethyl-Al water-dispersible granules.
Technical scheme of the present invention
A 80% phosethyl-Al water-dispersible granules, counts by weight percentage, and its composition and content are as follows:
The former medicine 85-87% of 95% phosethyl-Al
50% alkyl glycoside 2-5%
Empgen BB 2-5%
Binding agent gum Arabic 1-5%
Filler ammonium sulfate or urea 5-10%;
The preparation method of above-mentioned a kind of 80% phosethyl-Al water-dispersible granules, be about to that 95% phosethyl-Al, 50% alkyl glycoside, empgen BB, gum Arabic mix rear pulverizing with filler ammonium sulfate or urea, add water mixing, granulation, be dried, finally obtain 80% phosethyl-Al water-dispersible granules;
The fineness <23um of the material after pulverizing is controlled in described pulverizing;
Material after pulverizing adds water and mixes, and calculates in mass ratio, and amount of water accounts for 7% of material total amount;
Described granulation carries out extruding pelletization by screw extruder pelletizer;
The described dry Vibratingfluidbeddrier that adopts is dry, controls dryer gas phase temperature <120 ℃, granula moisture content <0.6% after control oven dry.
Beneficial effect of the present invention
In 80% phosethyl-Al water-dispersible granules of the present invention, physical property due to the former medicine of phosethyl-Al, particularly through pulverizing the former medicine of processing fineness >600 order, wetting in water, bad dispersibility, easily flocculation, the poor easy fragmentation of particle intensity after processing granula, make to phosethyl-Al water-dispersible granules and bring certain difficulty, the present invention is by selecting novel environment friendly non-ionic surface active agent alkyl glycoside (APG) and empgen BB to form the compound auxiliary agent of high osmosis, guarantee the former medicine of fineness >600 order phosethyl-Al, after adding appropriate this compound auxiliary agent, in water, there is better wetability, dispersed, higher suspension rate, and the use of this compound auxiliary agent reduces the surface tension of phosethyl-Al original liquid to crop, greatly improve the interior suction conducting power of phosethyl-Al original liquid in crop, thereby control efficiency obviously increases.
Further, 80% phosethyl-Al water-dispersible granules of the present invention, according to the characteristic of the former medicine material of phosethyl-Al in conjunction with water-dispersible granules granulation mode, select hydrophilic agglomerant gum Arabic, because the use of binding agent not only facilitates material granulating and forming, and the intensity of increase granula, more than making particle ratio of briquetting >96%, the phosethyl-Al original liquid that contains a certain amount of this binding agent has adhewsive action to crop blade face, resistance of rainwater washing against, thereby prolongation phosethyl-Al medicine original is imitated effective control phase.Minimizing, to crop spraying times during prevention of damage by disease, treatment, has been saved agriculture originally.
Further, 80% phosethyl-Al water-dispersible granules of the present invention, is filler owing to selecting ammonium sulfate or urea, therefore, when preventing and treating disease for crop, has also played crop is applied to chemical fertilizer, makes Crop nutrient, is more conducive to the effect of plant growth.
