Water emulsion of hostathion and preparation method thereof

Abstract

The invention discloses a triazophos aqueous emulsion and its preparing process, wherein the aqueous emulsion comprises 25-50% of triazophos, 5-15% of emulsifying agent, 1-4% of stabilizer, 0-10% of auxiliary solvent, 0-2% of dispersing agent, 0-3% of thickening agent, 0-4% of anti-freeze agent, and balancing water as dispersive medium. The emulsion is prepared through shearing emulsification or high-pressure homogeneity process and homogeneous decentralizing.

Description

Technical field:

[0001] The invention relates to an insecticide and acaricide, in particular to an aqueous emulsion containing triazophos and a preparation method thereof. Background technique:

[0002] Organic solvents in pesticide emulsifiable concentrates not only cause a waste of petroleum resources and increase production costs, but also pollute the environment and are harmful to pesticide applicators. In some countries, the use of emulsifiable concentrates containing aromatic hydrocarbon solvents has been restricted or banned, which has prompted Pesticide formulations are constantly updated and developed, among which water-based formulation is one of the leading directions for the development of pesticide formulations.

[0003] Pesticide emulsion in water (Emulsion oil in water, EW) is the water-insoluble original drug liquid or the liquid obtained by dissolving the original drug in a water-insoluble organic solvent as the dispersed phase, with the aid of emulsifiers a...
