【摘要】 以环己烷为油相,AASpan80/黄原胶/Span80为复配分散稳定剂,过硫酸钾和亚硫酸氢钠为引发剂,N,N’-亚甲基双丙烯酰胺为交联剂,丙烯酸、丙烯酸钠为单体,采用悬浮聚合法合成高吸水性树脂。考察了交联剂用量、聚合温度、反应时间等对高吸水性树脂吸水率影响,确定了最佳实验条件。实验结果为:环己烷100 mL,水相50 mL,水相中丙烯酸-丙烯酸钠浓度为3 mol/L,反应时间为3 h,反应温度为63℃。更多还原

【Abstract】 Acrylic acid,sodium acrylate solution were used to synthesize super absorbent resin agent by means of inverse suspension polymerization with cyclohexane was used as continuous phase and water as dispersed phasa and AASpan8/Xanthan gum/Span80 as the compound emulsifier and N,N’-methylenebisacrylamide as cross-linking and Potassium persulfate and sodiumbisulfite as initiator.The effects of dosages of cross-linking agent,reaction temperature,reaction time on thickener viscosity have been studied.The optimum experimental conditions were determined,and the ideal reaction conditions determined as follows: Cyclohexane 100 ml; water 50 ml; the mass ratio of compound emulsifier is: m（Span80 AA）∶m（Xanthan gum）∶m（Span80）= 0.8∶0.3∶0.1 and monomer concentration is 3 mol·L^-1;reaction time is 3 h,reaction temperature is 63℃.as well as its good anti-imbibition,anti-electrolyte,and rheological behavior.更多还原
