Abstract
The invention relates to paraquat-containing water dispersible granules for a pesticide herbicide and a preparation method thereof. The invention aims to solve the problem of animal poisoning of the existing paraquat water dispersible granules in the processes of production, storage and use. The technical scheme of the invention is as follows: paraquat water dispersible granules comprise the following components in percentage by weight: 5 to 95 percent of paraquat; 0.1 to 2 percent of wetting agent; 3% -8% of dispersant; 1% -35% of disintegrating agent; 0.1 to 4 percent of stabilizer; 0.1 to 4 percent of adhesive and 100 percent of filler. The paraquat water dispersible granule processed by the formula has the characteristics of good weeding effect, quick disintegration, good dispersibility, small environmental pollution, safety for users, simple package, convenient storage and transportation and the like.
Description
Technical field
The present invention relates to a kind of paraquat water dispersible granules and preparation method thereof that contains, specifically, what the present invention relates to that a kind of pesticide herbicide uses contains paraquat water dispersible granules and preparation method thereof.
Background technology
Paraquat, chemical name are 1-1-dimethyl-4-4-bipyridine cation salt, are a kind of quick steriland herbicides, have action of contace poison and certain systemic action.Can make it withered rapidly by the green plant tissue absorption.To the not effect of non-chlorenchyma.In soil, combine and purifying with soil rapidly, invalid to plant root and perennial subterranean stem and perennial root.Be the quick-acting contact killing types natural disposition quaternary ammonium salts weed killer herbicide that goes out.Active ingredient is extremely strong to chloroplast tunic destructive power; Make the synthetic termination very soon of photosynthesis and chlorophyll; Blade behind the medicine and promptly to be begun the variable color of being injured in 2-3 hour; Gramoxone all has very strong destruction to unifacial leaf and dicotyledon chlorenchyma, is one of product of consumption maximum in the present weed killer herbicide kind.But paraquat has only the aqua kind in the market, and the user eats by mistake easily and poisons, and is very big to people's toxicity; And there is not specific drug; The oral ingestion lethality can reach more than 90%, in order to solve the harm of aqua to human body, paraquat is made the poisoning problem that water dispersible granules has solved the people.
Summary of the invention
The present invention aims to provide a kind of paraquat water dispersible granules and preparation method thereof that contains, to solve the poisoning problem of paraquat.With this paraquat water dispersible granules graininess that contains provided by the invention, disintegration is fast, good dispersion, little, the easy to use, safe coefficient of environmental pollution are high, little to human harm.
Another object of the present invention provides a kind of preparation method of above-mentioned paraquat water dispersible granules.
Technical scheme of the present invention is: a kind of paraquat water dispersible granules comprises following component by weight percentage:
Selected wetting agent is for being selected from NPE; OPEO; Aliphatic alcohol sulfate; Lauryl sodium sulfate; The alkylol polyethenoxy ether sodium sulfate; Alkyl phenol polyethenoxy ether sodium sulfate; APES formaldehyde condensation products sulphate; Sodium alkyl sulfonate; Sodium alkyl benzene sulfonate; Alkylnaphthalene sulfonate; Dialkyl succinylsuccinate sulfonate; Monoalkyl phenyl APEO succinic acid sodium sulfonate; Fatty alcohol ethylene oxide adduct sulfonate; Alkylphenol formaldehyde condensation product ethylene oxide adduct sulfonate; In the alkyl amide taurate one or more.
Selected dispersant is to be selected from aliphatic alcohol polyethenoxy base ether, naphthalenesulfonate formaldehyde condensation compound, alkylphenol-polyethenoxy base ether, lignosulfonates, polycarboxylate, farming breast 602, farming breast 33, farming breast 34, the castor oil series one or more.
Selected disintegrant is to be selected from urea, white sugar, gluconic acid sodium salt, sodium carboxymethylcellulose, ammonium sulfate, ammonium chloride, anhydrous sodium sulfate, calcium chloride, layer silicon, surfactant, bentonite, the polyethyl acrylate one or more.
Selected synergist is to be selected from spreader-sticker, stabilizing agent, warning colouration, in anti-elegant dose one or more.Selected knot agent is to be selected from xanthans, aluminium-magnesium silicate, sucrose, gelatin, polyvinyl alcohol, polyvinylpyrrolidone, polyethylene glycol, starch, the sodium carboxymethylcellulose one or more.
In said components, paraquat, promptly former medicine is as pesticide herbicide.Wetting agent, dispersant, disintegrant and synergist general designation auxiliary agent are in the preparation of product and the general name of the various supplies that use in using, and do not have biologically active as the one of which.It is rapid that wetting agent, dispersant are used for product entry disintegration, and former medicine can be by the moistening dissolving of water; Disintegrant, it can help former medicine to be evenly dispersed in the preparation; Synergist can prevent active ingredient decomposition, prevent the person poultry poisoning, increase herbicidal effect etc.
Prepare the method that contains the paraquat water dispersible granules of the present invention, may further comprise the steps:
(1) by weight percentage, with component paraquat 5%～95%, wetting agent 0.1%～2%, dispersant 3%～8%, disintegrant 1%～5%, synergist 0.1%～4%, binding agent 0.1%～4%, mix the back and get into the cracker pulverizing;
(2) step (1) gained material is mediated, granulation, required paraquat water dispersible granules finally is processed in oven dry.
The paraquat water dispersible granules that adopts prescription of the present invention to process, its implementation result show that this product in use has safe in utilization, the characteristics that herbicidal effect is good.
Description of drawings
Through the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the present invention will become apparent and understand easily.
Fig. 1 is paraquat water dispersible granules technological process of production figure of the present invention.
