Abstract

The invention discloses a furfuran hydrazide insecticidal suspending agent and preparing method, which is composed of furfuran hydrazide with structural formula as formula (I) and suspending agent. The preparing method comprises the following steps: placing furfuran hydrazide and insecticidal suspending agent in the cutting autoclave, staring high-cutting emulsifying machine, blending the cut material evenly, grinding for 1-2 times.

Description

technical field [0001] The invention relates to an insecticide, in particular to a furanfenozide insecticidal suspension, and also relates to a preparation method of the insecticidal suspension. Background technique [0002] Suspending agents are mostly solid pesticides with low water solubility and high melting point (generally > 60°C), adding suitable wetting agents, dispersion suspending agents, tackifiers, antifreeze agents, preservatives and water and other components, Made by wet grinding with sand mill. The characteristics of this dosage form are: (1) Good drug effect: the average particle size of the dispersed solid drug in the suspension is 2-3 microns, the particles are close to spherical, the particle size range is small, and the distribution is uniform; Micro-bubbles are adsorbed on the surface of the particles, thereby improving the suspension rate and stability; after spreading, the adhesion is strong and it is resistant to rain erosion. Therefore, the dru...
