36%二氯异噁草酮悬浮剂的研制OA

To develop a 36%Bixlozone Suspension Concentrate(SC),a systematic study was conducted on the effects of different co-formulant systems on formulation performance.Focus was placed on investigating the compatibility and proportion of wetting and dispersing agents(lignin,sulfonate complexes,polycarboxylates,etc.),thickeners(silica,magnesium aluminum silicate,etc.),and antifreeze agents(ethylene glycol).They were evaluated using indicators including accelerated storage stability,low-temperature stability,particle size distribution,suspensibility,and flowability.The results showed that the optimal formulation consisted of 5%lignin 88A,1%polycarboxylate D205,and 2%DS539 as wetting and dispersing agents;2%silica as the filler;0.05%xanthan gum+0.5%magnesium aluminum silicate SF04 as thickeners;5%ethylene glycol as the antifreeze agent;and 0.2%defoamer,with deionized water added to make up the balance to 100%.The prepared SC exhibited controllable particle size growth(D90＜7 μm)after accelerated storage,suspensibility less than 15%,and qualified wet-sieving performance,meeting the technical indicators for SC formulation and demonstrating excellent system stability.This study provides a formulation basis for the industrial production of 36%Bixlozone SC.
