Abstract

The invention discloses a method for preparing pesticide emulsion in water by ultrasonic emulsification and a pesticide emulsion in water prepared by the method. Compared with the prior art, the pesticide emulsion in water, which is prepared by the method of the invention, has smaller particle size range, thus the pesticide emulsion in water has the advantages of favourable stability, high pesticide effect and the like; meanwhile, compared with the currently universal high-shear and homogenizing emulsification, the emulsion in water, which is prepared by ultrasonic emulsification, has the advantages of simple preparation, high production efficiency, low cost, high emulsification quality and the like.

Description

technical field

[0001] The invention relates to a pesticide preparation, in particular to a pesticide emulsion in water and a preparation method thereof. Background technique

[0002] As an environment-friendly water-based pesticide preparation, the research and industrialization of pesticide emulsion in water have made remarkable progress in recent years. Since all or most of the organic solvents are replaced by water, the water emulsion has the advantages of environmental friendliness, low toxicity, low residue, low processing cost, high safety during production, storage, transportation and use. However, the existing water-emulsion emulsion has an average droplet size of 0.2-5 μm and a droplet size distribution range of 0.1-10 μm, which belongs to a thermodynamically unstable system, and also has some disadvantages in practical applications, such as being difficult to stabilize (inherent instability) ), prone to delamination; production conditions and process requirements...
