Abstract

The invention discloses a dispersing agent special for a pesticide water suspension agent and a preparation method thereof, relates to the technical field of agriculture, and aims to provide the dispersing agent special for the pesticide water suspension agent, which has the advantages of simple operation, low cost and safety and environmentally friendly effect and the preparation method thereof. The dispersing agent special for the pesticide water suspension agent is prepared from the following raw materials in parts by mass: 100 to 600 parts of 2-vinylpyridine, 100 to 900 parts of organic acid, 1000 parts of deionized water, 10 to 150 parts of chain transfer agent, 10 to 150 parts of initiator and 6 to 20 parts of alkali. The dispersing agent special for the pesticide water suspension agent has the characteristic of large molecular weight; the dispersing agent is used as an auxiliary to prepare the pesticide water suspension agent, the dosage of the dispersing agent is little, and the prepared pesticide water suspension agent has good dispersibility and high suspension rate in standard hard water. The dispersing agent special for the pesticide water suspension agent has the advantages of simple preparation process, short production period and low production cost, has no environmental pollution in the production process, and is suitable for industrial scale production.

Description

technical field

[0001] The invention relates to the technical field of agriculture, in particular to a dispersant for pesticide water suspensions. 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 through steric hindrance and e...
