Embodiment 1

[0019] Example 1 : (5% emamectin suspension concentrate).

[0020] First weigh the following materials in proportion: emamectin 5%, fatty alcohol polyoxyethylene alcohol 1%, naphthalenesulfonate formaldehyde condensate 1.5%, polycarboxylate dispersant 2%, nano-titanium dioxide 5%, White carbon black 1%, aluminum magnesium silicate 1.5%, XG 0.08%, propylene glycol 5%, silicone defoamer 0.3%, deionized water balance. Then use deionized water to dissolve fatty alcohol polyoxyethylene alcohol, naphthalenesulfonate formaldehyde condensate, polycarboxylate dispersant, and propylene glycol, and then add them to the reaction kettle with stirring and mixing functions, turn on the stirring and shearing, and then put the Nano-titanium dioxide and emamectin benzoate raw materials are fully mixed and then added to the reaction kettle. Finally, white carbon black, propylene glycol, and silicone antifoaming agent are added and mixed evenly. , and finally poured into the shearing tank, addi...

Abstract

The invention relates to a pesticide suspending agent containing an inorganic nano-material and a preparation method thereof. The suspending agent comprises the components of pesticide active ingredients, an inorganic nano-material, a wetting dispersant, a thickening agent, an antifreeze, an antifoaming agent and water. The method comprises steps of: dissolving the wetting dispersant and antifreeze with deionized water, and adding the mixture into a reaction kettle; fully mixing the nano-material and an emamectin benzoate chlorfenapyr original drug, and adding the mixture into the reaction kettle; and mixing, grinding and shearing. The pesticide suspending agent provided by the invention has strong anti-photolysis performance, and increases utilization rate of the pesticide and reduces the application amount and usage frequency of the pesticide; in addition, the pesticide suspending agent can sterilize for a long time under the effect of ultraviolet ray in the light, so as to reduce the usage amount of the bactericide pesticide.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a pesticide suspension containing inorganic nanomaterials and a preparation method thereof. Background technique [0002] According to research, most of the active ingredients of pesticides will accelerate their decomposition speed under sunlight exposure. If the decomposition speed is not high, it is benign. If the decomposition speed is too fast, it will affect the active ingredients to play a role. This leads to repeated use of pesticides by farmers, which increases costs and increases the risk of environmental pollution. Especially those containing double bond structure in the structure of the active ingredient are especially unstable to light. A large number of studies and literature have shown that photolysis may first be an oxidation reaction, that is, the transition from a non-oxidized state to an oxidized state. The mechanism may be that when the oxygen in the ...
