(ZH) 一种含阿特拉津和精异丙甲草胺的微囊悬浮-悬浮剂及其制备方法
Abstract
(EN)
A microcapsule suspension-suspending agent containing atrazine and s-metolachlor and a preparation method therefor. The method comprises: a. mixing a urea-formaldehyde resin prepolymer aqueous solution and s-metolachlor oil emulsion at a weight ratio of 1: (0.5-2) to obtain a first material; b. adjusting the pH of the first material to 5.0-6.5 to obtain a second material; c. adjusting the pH value of the second material to 2.5-4.5 to obtain a third material; d. subjecting the third material to curing polycondensation, and then adjusting the pH value of the material subjected to the curing polycondensation to be neutral and mixing with a first dispersant, a thickener, and antifreeze uniformly to obtain a fourth material; and e. after mixing the fourth material with an atrazine suspending agent, adding a second dispersant, and mixing uniformly. The preparation method significantly improves the storage stability of a microcapsule suspension-suspending agent containing atrazine and s-metolachlor and the control effect on weeds.

Agent de suspension à suspension de micro-capsule contenant de l'atrazine et du s-métolachlore et son procédé de préparation. Le procédé consiste à : a. mélanger une solution aqueuse de prépolymère de résine d'urée-formaldéhyde et d'une émulsion d'huile de s-métolachlore selon un rapport pondéral de 1:(0,5-2) pour obtenir un premier matériau ; b. ajuster le pH du premier matériau à 5,0-6,5 pour obtenir un deuxième matériau ; c. ajuster la valeur du pH du deuxième matériau à 2,5-4,5 pour obtenir un troisième matériau ; d. soumettre le troisième matériau à une polycondensation de durcissement, puis ajuster la valeur du pH du matériau soumis à la polycondensation de durcissement pour qu'elle soit neutre et mélanger avec un premier dispersant, un épaississant et de l'antigel de façon uniforme pour obtenir un quatrième matériau ; et e. après le mélange du quatrième matériau avec un agent de suspension d'atrazine, ajouter un second dispersant, et mélanger uniformément. Le procédé de préparation améliore considérablement la stabilité au stockage d'un agent de suspension à suspension de micro-capsule contenant de l'atrazine et du s-métolachlore et l'effet de lutte contre les mauvaises herbes.
