Abstract
The invention relates to a preparation method of imidacloprid suspension concentrate. The method is characterized in that an imidacloprid original drug is adopted as a raw material, water is adopted as a solvent, calixarene is added as a dispersant and emulsifier in order to prepare the imidacloprid suspension concentrate, and the calixarene is sulfonic calix[5]arene. The imidacloprid suspension concentrate with the content of 350g/L is prepared by adding the novel calixarene as the dispersant and emulsifier to the raw material imidacloprid original drug, and enables the product suspension rate to reach above 95%.
Description
Technical field
The present invention relates to a kind of preparation method of imidacloprid suspending agent, belong to preparation technique of pesticide field.
Background technology
Imidacloprid is nicotinoids super-high-efficient insecticide, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to features such as people, animal, plant and natural enemies securities, and have tag, the multiple action such as stomach toxicity and interior suction.Be mainly used in preventing and treating sucking pest, as aphid, aleyrodid, leafhopper, thrips etc.
Suspendability is an important indicator that ensures Imidacloprid insecticidal properties, therefore how to improve its suspendability and just seems very important.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of preparation method of the imidacloprid suspending agent that can improve Imidacloprid Suspension index.
The technical solution used in the present invention is for this reason: the present invention carries out according to the following steps: taking the former medicine of Imidacloprid as raw material, taking water as solvent, adding calixarenes is that dispersant and emulsifier process imidacloprid suspending agent, and described calixarenes is sulfonation cup [5] aromatic hydrocarbons.
Calixarenes addition is the 0.5%-2% of Imidacloprid quality.
Advantage of the present invention is: the present invention adopts taking the former medicine of Imidacloprid as raw material, and adding from Calix aromatic hydrocarbons is that dispersant and emulsifier are processed 350 grams per liter imidacloprid suspending agents, and product suspensibility is reached more than 95%.
