In the making method, pelletizing, chemical impregnating and coating procedure is adopted. The weight pencents of the ingredients of said pren. are as follows: aldicarb 5-25%, organic carrier 10-40%, inorganic carrier 30-60%, binder 0.1-1%, coating agent 1-15%, warning colour 0.1-3%. Said pesticide is mainly used to kill the mite, nematode and other injurious insect. The making method features rational technological design, no environmental pollution, low cost, convenient operation, good insecticidal resulats and durable efficacy of pesticide.
Description
The present invention relates to a kind of process for preparing insecticide, specifically a kind of spacetabs type Aldicarb coated granule insecticide that in soil, uses and preparation method thereof.
The Aldicarb insecticide in nineteen sixty-five by reports such as M.H.J.Weiden, produce by U.S. Union Carbide Corp. company, now produce by French Rhone-Poulenc Agrochimie company.This agent belongs to high-toxic pesticide, is 0.81-0.93mg TC/Kg to white mouse acute oral toxicity test LD50 great and mighty or powerful; Dead in following 5 minutes of the big white mouse 0.2mg/L air concentration; Human aceptable daily intake (ADI) is the 0.005mg/Kg body weight.Aldicarb preparation on the existing market, single agent mainly is a granule, the Aldicarb content of making carrier with corncob is 100 or 150gAI/KG, three kinds of specifications such as the granule of making carrier with gypsum has 50,100,150g/Kg.The manufacture craft of above-mentioned granule mainly is the kneading method of one-step shaping, and its technology adds the former medicine or the pulvis of Aldicarb for carrier powder is broken to certain fineness, is kneaded into spherical shape, as sale of finished goods.The advantage of kneading method prilling is: the particle fluidised form is good, grain shape is regular, the high difficult fragmentation of intensity etc., and shortcoming is that cost height, production efficiency are low, the malicious operation of open type belt, and intoxication accident easily takes place, operating personnel seriously polluted to operating environment.At present, also do not have the first granulation of employing to soak medicine again, back dressing is produced the reported in literature of high toxicity Aldicarb coated granule pesticide product and technology, and the application report of Aldicarb coated granule insecticide aspect the crops deinsectization do not arranged yet.
The purpose of this invention is to provide that a kind of technology is simple, production cost is low, production security is strong, operating personnel's long Aldicarb coated granule insecticide of danger, environmentally safe and lasting period and preparation method thereof of not poisoning.
The objective of the invention is to realize in the following manner: adopt first granulation, after soak medicine, the technology of Bao Fuing again.Adopt the extrusion molding granulation, thereby production efficiency improved significantly, owing to do not take the medicine operation in the granulation process, thereby can in the airly protect facility, can openly produce, reduce equipment investment.The particle of producing soaks medicine and dressing in airtight container, thereby high safety, and environmentally safe, and mechanization degree height can make production cost reduce significantly.This granule adopts art for coating in addition, and the granule slow release is increased substantially, and the lasting period reached more than 60 days.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, the dressing that soaks medicine, granule that comprises feedstock production, carrier granulation, particle, this method adopts first granulation, after soak medicine, the preparation method of Bao Fuing again, the weight percent of each composition of said preparation consists of: the former medicine 5-25% of Aldicarb, organic carrier 10-40%, inorganic carrier 30-60%, binding agent 0.1-1%, seed coating medicine 1-10%, warning color 0.1-3%.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, employed inorganic carrier is in the raw material: the mixture of one or more in potter's clay, atlapulgite, diatomite, bentonite, talcum, calcium carbonate, gypsum and the brick powder, mixture with potter's clay, gypsum and common brick powder is best, and smashing fineness is 200 orders.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, employed organic carrier is in the raw material: wood chip, corncob and crop stalk are best with the mixture of wood chip and corncob, and smashing fineness is 200 orders.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, binding agent can be one or more the mixture in starch, dextrin, arabia gum, soybean protein, polyvinyl acetate, polyvinyl alcohol and the waterglass, is preferably polyvinyl alcohol and waterglass.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, employed seed coating medicine is: the mixture of one or more in paraffin, pitch, polyvinyl alcohol, polypropylene, PIC, the acrylic polyester is best with paraffin.
In Aldicarb coated granule insecticide of the present invention and preparation method thereof, warning color can be a kind of in carbon black or the graphite.
Aldicarb coated granule insecticide of the present invention and preparation method thereof; prilling process is an extrusion molding; in proportion fineness is added in a mixing bowl less than 200 purpose organic carriers, inorganic carrier and adhesive; stir; cause particulate vector through the extruded type comminutor, particulate vector is dry for standby under 100-500 ℃ temperature.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, the particulate vector of oven dry is put into a mixing bowl again, organic solvent and the former medicine of Aldicarb added in a mixing bowl in the mixed solution of 3: 1 ratio stir, the solution that contains former medicine is fully adsorbed by particulate vector, temperature with a mixing bowl rises to 50 ℃ while stirring, start the vavuum pump vacuum distillation recovered solvent, vacuum degree control is at 0.01-0.08MPa, solvent adopts the chlorohydrocarbon of C1-C3, is best with tetrachloromethane, dichloroethane.
Aldicarb coated granule insecticide of the present invention and preparation method thereof, the particulate vector that contains Aldicarb that removes solvent is warming up to 65-70 ℃ in a mixing bowl, add paraffin and carry out dressing, stirring 2-4 minute dressing finishes, add warning color carbon black or graphite again, while stirring a mixing bowl is cooled to room temperature rapidly, the granule finished product is poured out just can be packed sale.
