Problems solved by technology

But these dosage forms of sodium rosinate have many unavoidable shortcomings: sodium rosinate emulsifiable concentrate, use a large amount of organic solvents to put into environment, cause environmental pollution and waste of resources serious; Sodium rosinate aqueous emulsion pesticide is unstable in water, long-term storage easily decomposes Failure; Sodium rosinate microemulsion often undergoes the following changes during storage: stratification, flocculation, phase inversion, demulsification, rancidity, etc.
Theoretically, sodium rosinate is processed into water-dispersible granules, which can overcome the existing defects of other dosage forms, and has a series of advantages of water-dispersible granule pesticides, but on the market, sodium rosinate insecticides are not Water-dispersible granules are never present

Abstract

The invention discloses a sodium abietate insecticide and a preparation method thereof. The sodium abietate insecticide is a water dispersible granule containing 15wt% of sodium abietate. The preparation method comprises the following steps of: A, weighting a soluble powder containing 20wt% of sodium abietate, and mechanically crushing into granules of 180-200meshes; B, evenly mixing the soluble powder containing 20wt% of sodium abietate, sugar-free sodium lignin sulfonate, sodium sulfate and a dispersant, and crushing the mixture by a jet mill at the pressure of 600kg; C, dropwise adding a liquid substance, evenly stirring, and prilling by a rotary granulator; and D, placing in a thermostat, and drying for 8-10 hours at 54 DEG C to obtain the water dispersible granule containing 15wt% of sodium abietate. The sodium abietate water dispersible granule has the advantages of a water dispersible granule. By combing the technical process disclosed by the invention, the sodium abietate insecticide and a preparation method thereof are worthy of popularization.

Description

technical field [0001] The invention relates to a sodium rosinate insecticide and a preparation method thereof. Background technique [0002] Sodium rosinate is a new type of low-toxic botanical biopesticide based on natural raw materials. The active ingredient is sodium rosinate. So far, the formulations that have been invented include emulsifiable concentrate, emulsion in water, microemulsion, and soluble powder. But these dosage forms of sodium rosinate have many unavoidable shortcomings: sodium rosinate emulsifiable concentrate, use a large amount of organic solvents to put into environment, cause environmental pollution and waste of resources serious; Sodium rosinate aqueous emulsion pesticide is unstable in water, long-term storage easily decomposes Failure; Sodium rosinate microemulsion often undergoes the following changes during storage: stratification, flocculation, phase inversion, demulsification, rancidity, etc. And liquid pesticides are not conducive to storag...
