Embodiment 1

[0016] According to the technical scheme of the present invention, weigh 7% of Flonicamid technical, 5% of methanol, 10% of xylene, 3% of castor oil polyoxyethylene ether, 2% of fatty alcohol polyoxyethylene ether, and alkylphenol formaldehyde resin. Polyoxyethylene ether sulfate 1%, coke gallic acid 2%, peanut oil 2%, mix and fully dissolve to obtain the oil phase; mix 4% ethylene glycol and the remainder of deionized water in the preparation kettle and make it The water phase, after turning on the stirring, slowly add the oil phase to the water phase, and shear at 6000 revolutions per minute for 30 minutes to obtain a 7% flonicamid water emulsion.

Embodiment 2

[0018] According to the technical scheme of the present invention, weigh 10% of Flonicamid technical, 3% of ethyl acetate, 15% of Solvesso200, 2% of alkylphenol polyoxyethylene ether, polyhydric alcohol fatty acid ester and its ethylene oxide addition 1.5% of the final product, 2% of sodium di-octyl maleate sulfonate, and 1% of polycarboxylates.

[0019] Mix antioxidant 264 2% and peanut oil 3% to fully dissolve the oil phase; mix glycerol 4% and the remainder of deionized water in the preparation kettle and then make the water phase, turn on the stirring and slow the oil phase Add to the water phase, shear at 6000 revolutions per minute for 30 minutes to obtain a 10% flonicamid water emulsion.

Embodiment 3

[0021] According to the technical scheme of the present invention, weigh out Flonicamid original drug 15, ethanol 3%, and Solvesso 150 20%.

[0022] Castor oil polyoxyethylene ether 4%, polyoxyethylene sorbitan fatty acid ketone 2%, fatty alcohol polyoxyethylene ether 1%, alkylphenol formaldehyde resin polyoxyethylene ether sulfate 1%, epoxy soybean oil 5% , Mix and fully dissolve to obtain the oil phase; mix 4% glycerol and the balance of deionized water in the preparation kettle and then make the water phase. After turning on the stirring, slowly add the oil phase to the water phase at 6000 rpm Cut for 30 minutes to obtain 15% flonicamid water emulsion.

[0023] The flonicamid water emulsion product of the present invention has stable performance, is easy to produce and store, is environmentally friendly, and is safe to use. Tests have proved that it has a good control effect on vegetable aphids such as cucumber and cabbage and fruit tree aphids such as apples and citrus. The av...

Abstract

The invention discloses a flonicamid water emulsion and a method for preparing the flonicamid water emulsion. The flonicamid water emulsion comprises the following components in percent by weight: 1-15% of flonicamid, 3-25% of solvent, 4-15% of emulsifying agent, 0.5-2% of dispersing agent, 1-5% of stabilizing agent, 1-5% of anti-freezing agent and the balance of deionized water. The method for preparing the flonicamid water emulsion comprises the following steps: dissolving the flonicamid into the solvent, adding the emulsifying agent, the stabilizing agent and the dispersing agent to prepare an oil phase, mixing the anti-freezing agent with the deionized water to prepare a water phase, and adding the oil phase into the water phase or the water phase into the oil phase slowly under the high shearing condition to prepare the flonicamid water emulsion. The flonicamid water emulsion is a safe and environmentally friendly agricultural pesticide with a good effect.

Description

Technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a flonicamid water emulsion and a preparation method thereof. Background technique [0002] Flonicamid is effective against various piercing and sucking mouthparts pests and has a good penetration effect. It can penetrate from the root to the stem and leaf, but the penetration from the leaf to the stem and root is relatively weak. The medicine works by hindering the sucking action of the pests. The pests stop sucking soon after taking the medicine, and finally die of starvation. Due to its unique mechanism of action and extremely high biological activity, as well as its high safety to humans, animals and the environment, and its effectiveness against other insecticide-resistant pests, it has a lot of room for development . [0003] Modern pesticide formulations are developing towards water-based, ultra-micronization, non-powdering and controlled release, tha...
