Abstract

The invention discloses a processing technology of a novel formula suspension agent with high penetration and rainwash resistance. The processing technology comprises the following steps: weighing each raw material according to the formula, wherein the suspension agent is prepared from the following components in parts by weight: 30-40 parts of imidacloprid, 3-4 parts of emulsifier, 2-3 parts of anti-caking agent, 1-3 parts of preservative, 3-5 parts of antifreeze agent, 3-7 parts of thickener, 2-6 parts of high-penetration agent, 2-6 parts of antifoaming agent, 1-4 parts of dispersing agent,and 50-65 parts of water; dispersing at high speed; grinding; and feeding for the second time. The suspension agent prepared by the processing technology has better dispersibility and spreadability and high suspension rate, and can adhere to the surfaces of plants closely and resist rain washing, so that the effect of the suspension agent is more significant and lasts longer than that of wettablepowder; the suspension agent has good quick-acting property and long lasting effect, which lowers the application frequency and reduces the labor cost; the processing technology and the suspension agent are both environmentally friendly and have good market potential.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a processing technology for a new formula suspending agent of a high-osmosis and anti-rainwater scouring auxiliary agent. Background technique [0002] Suspending agent is a viscous and flowable suspension formed by mixing the original pesticide, carrier and dispersant, and ultrafinely pulverizing it by wet method. The insoluble or slightly water-soluble solid original drug is dispersed in water relatively uniformly through ultrafine pulverization with the help of some additives, forming a stable liquid-solid system with fine particles, high suspension, and flowability. Suspending agents are usually composed of active ingredients, dispersants, thickeners, anti-sedimentation agents, defoamers, antifreeze agents and water. The content of active ingredients is generally 5% to 50%. The average particle size is generally about 3 microns. It is a new dosage form for pesticide processing. ...
