Abstract
The present invention relates to poison-less sanitary pesticide and its preparation process. The poison-less sanitary pesticide is prepared with artificially synthesized amorphous industrial SiO2 and sintered diatomite as main material, and through mixing in certain ratio, and adding pest attracting additive to raise the pesticidal effect. The present invention is suitable for preventing and controlling pests in household, animal and grains.
Description
The present invention relates to a kind of non-toxic sanitary insecticide and formulation method thereof, belong to the product and the manufacturing technology of chemical field.
The hygienic insecticide of existing use mainly is the organic phosphorus compound that chemical synthesis is produced, and the toxicity by these compounds kills off the insect pests.In use, can cause poisonous substance residual, contaminated environment, harm people's health.To kill the new medicine of cockroach (the mark Q/HDLXY001-2000 of enterprise) is example, and its active ingredient is go out young urea and orthene.This product can kill cockroach faster, is that product is assert by national Patriotic Health Committee.But this product is toxic, and the young urea that goes out is a hypotoxicity, and orthene (content is 5% in the prescription) toxicity is higher.The state health standards regulation, the highest limit the quantity of of orthene in food is 0.2mg/kg.If intoxicating phenomenon promptly can take place after contacting or suck with pet in the people.In addition, use this type of medicine that leans on the toxicity desinsection for a long time, insect is developed immunity to drugs, influence insecticidal effect.In addition, its production process also can cause in various degree pollution to environment.Adopt the nontoxic insect-proof agent (document 1) of amorphous SiO2 preparation, can kill household insects such as cockroach.But this product does not have the trapping function, influences result of use.In addition, this method is begun by basic material, and technological process is long, and investment is big, and is subjected to the restriction in the natural material place of production, and plant site selection is restricted.
At the above-mentioned deficiency of prior art, the invention provides a kind of non-toxic sanitary insecticide and formulation method thereof.With semi-finished product is raw material, and technological process is short, small investment, and the factory site is unrestricted, and products obtained therefrom has the function of insects such as trapping cockroach, ant.
The present invention realizes above-mentioned purpose by following technical measures.
1, burning till product (to call natural product in the following text) with the amorphous silica industrial goods (to call composite in the following text) of synthetic and diatomite is raw material, begins processing by semi-finished product, saves each operation of basic material processing.
2, adopt successively metering, drying, mixing sorting, classification 1, product by composite to mix, separate recoverys, packaging process and be exported between the product mixed processes inlet technological process of circulation pulverizing of Lian Jieing and classification 2 operations formation successively at classification 1 coarse fodder with natural product; Circulation is pulverized and is adopted high speed reflection-type mechanical crushing to replace the supersonic airstream pulverizing.
3, the technical recipe that adopts composite, natural product and nontoxic bait compound to mix mutually; According to the characteristics of insect, the composite ratio is adjusted in the 5-100% scope, and the ratio of natural product is adjusted in the 0-95% scope, and the bait compound is adjusted in the 0.1-3.0% scope.
After taking above-mentioned measure, product has the performance of insect-killing trapping, has improved insecticidal effect.Owing to begin processing from semi-finished product, technological process is shortened, and is not subjected to the restriction in the places of origin of raw materials.After the pulverizing of high speed reflection-type mechanical crushing replacement supersonic airstream, saved the air compressor of comminution by gas stream, power consumption and noise significantly reduce.
Fig. 1 is a process flow diagram of the present invention.Technical process is as follows:
Composite is after metering, drying, and the natural product mixing sorting with measuring discards impurity.The melange of sorting is sent into classification 1 classification by air-flow, and the satisfactory fines of particle diameter flows to into the product mixed processes; Undesirable coarse fodder is sent into the circulation pulverizing process.Materials flow after circulation is pulverized enters classification 2 classifications for the second time, and the product mixed processes is sent in the satisfactory materials flow of particle diameter; Undesirable material returns the circulation pulverizing process again to be continued to pulverize, until meeting the requirements.The bait compound is sent in the lump after mixing and is separated the disposable separation recovery of recovery process through being metered into the product mixed processes, and clean air enters atmosphere, and product packs at packaging process.
According to the different product requirement, select different physical indexs for use and the low composite of content of beary metal, ratio is adjusted in the 5-100% scope; Baking temperature is 105-250 ℃.Natural product select for use the diatomite that content of beary metal is low, specific surface area is bigger to burn till product, and ratio is adjusted in the 0-95% scope.The bait compound is selected according to pest species, and ratio is adjusted in the 0.1-3.0% scope.The critical particle diameter of classification 1 and classification 2 is adjusted in the 5-20 mu m range as required.Whole system adopts air-flow to carry negative-pressure operation.
