摘要
探讨了正丁胺对锂皂石的改性及与氟化钠改性膨润土进行复配对烷基烯酮二聚体(AKD)的乳化与稳定作用,同时研究了所制备的AKD乳液的浆内施胶性能。结果表明,当改性膨润土用量为4%(相对于AKD质量,下同)、正丁胺用量为6%(相对于锂皂石质量,下同)、锂皂石用量为2.5%(相对于AKD质量,下同)时,可将AKD乳化成水包油型Pickering乳液,并且所制备的乳液稳定性和施胶性能较好。
The modification of laponite by n-butylamine as well as the emulsification and stabilization of the modified laponite together with NaF modified bentonite on AKD were investigated,meanwhile the sizing performance of the AKD emulsion on BCTMP was also studied in this paper.The results showed that when the dosages of modified bentonite,n-butylamine,laponite were 4wt%(based on AKD),6wt%(based on laponite),and 2.5wt%(based on AKD),respectively,AKD Pickering emulsion(O/W type) with better emulsion stability and sizing performance was obtained.
