摘要:

利用十二烷基二甲基苄基氯化铵对钠基膨润土进行有机改性。对制得的1227有机膨润土(1227-ben)进行了红外光谱(FT-IR)分析,并将其作为抗沉降剂应用于4%烟嘧磺隆油悬剂的制备中,考察了1227-ben对4%烟嘧磺隆油悬体系物理性能的影响。红外分析结果表明,1227碳链进入到膨润土的片层间。沉降试验表明,随着1227-Ben的使用及其用量的增加,制剂析油率明显降低,粘度和屈服值则显著提高,并且体系悬浮率提高,可见十二烷基二甲基苄基氯化铵改性膨润土可以作为4%烟嘧磺隆油悬浮剂的抗沉降剂进行使用。

Abstract:

The anionic surfactant 1227 was first used to the preparation of sodium base betontte. The prepared 1227-ben was given further determination by FT-IR and used as subsidence-resistance for preparing 4% nicosulfuron oil-suspension. The effect of 1227-ben on the physical property of oil-suspension was examined eventually. FT-IR spectra showed that the organic agents had intercalated into the layer of montmorillonite. Subsidence-resistance test showed that the increase in 1227-Ben dosage could decrease oil separation rate and improve the viscidity and yield value and suspension rate of oil-suspension, that is, 1227-ben could be used as subsidence-resistance for the preparation of 4% nicosulfuron oil-suspension.

Key words: Organicallymodified bentonite,nicosulfuron oil-suspension,rheological characteristics,physical stability
