Technical Field

The invention belongs to the technical field of processing of suspending agents, and particularly relates to a pesticide suspending agent and a preparation method thereof.

Background

The suspending agent, the international code of which is SC, is a silk-sticky flowable suspension which is prepared by mixing an original pesticide, a carrier and a dispersing agent and carrying out superfine grinding by a wet method. The liquid-solid system is formed by dispersing solid raw medicine which is insoluble or slightly soluble in water uniformly through superfine grinding by means of certain auxiliary agents. The suspending agent is generally composed of active ingredients, a dispersing agent, a thickening agent, an anti-settling agent, an antifoaming agent, an antifreezing agent, water and the like. The content of the effective components is generally 5 to 50 percent. The average particle size is typically around 3 microns. Is a new formulation for processing pesticides.
