Abstract
The invention relates to diazinon emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The diazinon emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of diazinon, 5%-10% of emulsifying agent, 8%-12% of water-soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid diazinon and the emulsifying agent uniformly firstly; adding diazinon after mixing into a water solution of the water soluble polymer, and mixing uniformly, thus viscous emulsion is obtained; then adding the carriers into the viscous emulsion, thus a pre-granulating mixture is obtained; and finally granulating and drying. The granules provided by the invention are emulsifiable granules without adding an organic solvent, can be completely emulsified by adding water in use, can achieve good effect at low concentration, have quick acting and duration, and can maintain a long-term superior effect; and bactericidal effect is superior to other dosage forms with the same active ingredients.
Description
Technical field
The present invention relates to a kind of agricultural chemical insecticide, but but be specifically related to the preparation method of a kind of diazinon emulsification granula and diazinon emulsification granula.
Background technology
Diazinon is the organophosphorous pesticide (insecticidal/acaricidal agent) of wide spectrum, efficient, low toxicity; Have tag, stomach toxicity, stifling and certain systemic function; Its mechanism of action is acetylcholine esterase inhibition; Various pests such as Lepidoptera, Homoptera are all had favorable effect, and the control soil insect of also can dressing seed is applicable to the control of control tealeaves, fruit, cotton, paddy rice, wheat, vegetables, flowers and other crops insect and mite class.
At present, diazinon has microemulsion, aqueous emulsion and three kinds of formulations of missible oil, but these three kinds of formulations all have deficiency in quick-acting, lasting effect, the feature of environmental protection, have the not good problem of drug effect, needs to use heavy dose of diazinon just can reach the purpose of desinsection.And the used solvent of missible oil formulation (EC) mainly is aromatic hydrocarbon substances such as toluene and xylol, and promptly contaminated environment has been wasted a large amount of petroleum resources again, does not meet the requirement and the trend of agricultural sustainable development.
Summary of the invention
Said defective above the objective of the invention is to be directed against, but a kind of quick-acting is provided, lasting effect is excellent and the diazinon emulsification granula of environmental protection.
But another object of the present invention provides a kind of preparation method of diazinon emulsification granula.
The present invention seeks to be achieved through following technical scheme.
But a kind of diazinon emulsification granula is characterized in that, comprises the raw material of following weight portion: diazinon 20-60%, and emulsifier 5-10%, water-soluble polymer 8-12%, surplus is a carrier.
Said diazinon is a liquid.
Said emulsifier is selected from a kind of in nonionic and anion compounded surfactant, nonionic phosphate, the nonionic sulfuric ester.
Said water-soluble polymer is selected from a kind of in polyvinyl alcohol (PVA), sodium carboxymethylcellulose (CMC), the sodium carboxymethyl starch (CMS), is made into the aqueous solution by 1:8-12.
Said carrier is selected from a kind of in dextrin, sugar, urea, ammonium sulfate, glauber salt, carbonic hydroammonium, Sodium Benzoate, the soluble starch.
But a kind of preparation method of diazinon emulsification granula; It is characterized in that; Earlier that liquid diazinon and emulsifier is even, mixed diazinon is added in the aqueous solution of water-soluble polymer, mixes the emulsion that obtains thickness; Carrier is added in the emulsion of thickness again and obtain preparatory granulation mixture, last granulation is also dry.
The invention has the beneficial effects as follows: but 1, the present invention is for a kind of emulsification granula that does not add organic solvent, adds water emulsification fully during use, uses low concentration just can obtain high effect, drug effect is superior to other formulation of identical effective ingredient; 2, have quick-acting and lasting effect, can keep long-term superior effect; 3, said emulsifier has high HLB value; Be not easy to be saltoutd out; Said water-soluble polymer can keep colloidal stability in the preparation that solidifies; But can prepare the emulsification granula that contains the former medicine of a lot of liquid, said carrier is water-soluble, with the adsorbable a lot of liquid of the prilling process of rotation extrusion comminutor extrusion molding; 4, the particle body is convenient to packing and transportation.
