Abstract

The invention discloses a formula for a broad-spectrum aqueous pesticide suspension dispersant. The formula comprises, by mass, 150-500 parts of amino acids, 150-600 parts of an organic acid, 700-900parts of deionized water, 10-100 parts of a chain transferring agent, 10-100 parts of an initiator, 6-10 parts of an alkali, 12-20 parts of polyol and 6-18 parts of an antifoaming agent. The additionof the polyol in raw materials can improve the whole antifreeze effect, ensure the low-temperature stability and non-volatility of the dispersant and improve the stability of the aqueous pesticide suspension dispersant under low-temperature cold conditions; and the addition of the antifoaming agent and a mixed liquid of C8-10 fatty alcohols and C10-20 aliphatic carboxylic acids and esters thereofin the raw materials can effectively eliminate a large amount of bubbles in the processing process and improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a broad-spectrum pesticide aqueous suspension dispersant formulation. Background technique [0002] The so-called dispersant refers to a class of substances that can prevent the mutual aggregation of solid-liquid dispersion particles and keep solid particles uniformly dispersed in the liquid phase for a long time. [0003] Traditional dispersants mainly include anionic surfactants and nonionic surfactants. Anionic surfactants include: sulfonate surfactants, phosphate surfactants and sulfate surfactants. Nonionic surfactants include: alkylphenol polyoxyethylene phosphate and polyoxyethylene polyoxypropylene ether block copolymer. The most important of the traditional dispersants are lignosulfonate and its derivatives, naphthalene or alkylnaphthalene formaldehyde condensate sulfonate and its derivatives. [0004] The polycarboxylate dispersant can stabilize the system throug...
