Problems solved by technology

Among them, the powder needs to be dispersed in water before spraying. In order to make the powder disperse evenly, it is necessary to use solvents and additives to prevent uneven concentration or precipitation, which will ultimately affect the spraying effect.
Commonly used solvents and additives are organic solvents, which will cause great pollution to the environment during their use

Embodiment 1

[0018] Take 7 kg of methyl oleate, 1.5 kg of ethanol, 1 kg of triethanolamine dodecyl phosphate, and 1.5 kg of Tween-40. Weigh the above components by weight, mix dodecyl phosphate triethanolamine and Tween-40 with ethanol, then add methyl oleate, heat up to 45°C and stir to fully mix, then cool naturally have to.

Embodiment 2

[0020] Take 5 kg of methyl oleate, 0.5 kg of ethanol, 1.5 kg of triethanolamine dodecyl phosphate, and 1 kg of Tween-40. Weigh the above components by weight, mix dodecyl phosphate triethanolamine and Tween-40 with ethanol, then add methyl oleate, heat up to 50°C and stir to fully mix, then cool naturally have to.

Embodiment 3

[0022] Take methyl oleate as 8kg, ethanol as 2kg, dodecyl phosphate triethanolamine as 2kg, and Tween-40 as 3kg. Weigh the above components by weight, mix dodecyl phosphate triethanolamine and Tween-40 with ethanol, then add methyl oleate, heat up to 40°C and stir to fully mix, then cool naturally have to.

Abstract

The invention relates to a high-dispersive dispersant for pesticide. The high-dispersive dispersant for the pesticide is prepared from, by weight, 5-8 parts of methyl oleate, 0.5-2 parts of ethyl alcohol, 1-2 parts of anion surfactant and 1-3 parts of tween. The invention further relates to a preparation method of the dispersant. The dispersant is green, environmentally friendly, high in dispersion of pesticide and capable of enhancing the effect of the pesticide.

Description

technical field [0001] The invention relates to the technical field of pesticide solvents, in particular to a high-dispersion dispersant for pesticides. Background technique [0002] Pesticide formulations mainly include emulsifiable concentrates, water emulsions, microemulsions, soluble liquids and various powders. Among them, the powder needs to be dispersed in water before spraying. In order to disperse the powder evenly, solvents and additives are needed to prevent uneven concentration or precipitation, which will ultimately affect the spraying effect. Commonly used solvents and additives are organic solvents, which will cause great pollution to the environment during their use. Therefore, how to better improve the dispersion effect of pesticides in water, and increase the efficacy of pesticides while being green and environmentally friendly, has increasingly become the goal pursued by people. Contents of the invention [0003] The object of the present invention is ...
