Title
(EN) Microcapsule suspension-suspending agent containing atrazine and (S)-metolachlor, and preparation method of microcapsule suspension-suspending agent
(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)
The invention discloses a method for preparing a microcapsule suspension-suspending agent containing atrazine and (S)-metolachlor, and the microcapsule suspension-suspending agent. The method comprises the following steps: a. mixing a urea-formaldehyde resin prepolymer aqueous solution with (S)-metolachlor emulsifiable concentrate according to a weight ratio of 1 to (0.5-2) so as to obtain a firstmaterial; b. adjusting the pH value 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. carrying out solidification and condensation polymerization on the third material, then adjusting the pH value of the material, subjected to solidification and condensation polymerization, to be neutral, and then uniformly mixing with the product with a first dispersant, a thickener and an antifreezing agent to obtain a fourth material; e. mixing the fourth material with an atrazine suspension agent, then adding a second dispersant and evenly mixing. The preparation method provided by the invention significantly improves the storage stability and the control effect on the weeds of the microcapsule suspension-suspending agent containing the atrazine and the (S)-metolachlor.
