以N,N-亚甲基双丙烯酰胺为交联剂,1173为光引发剂,采用紫外光引发聚合的方法制备了高岭土/聚(丙烯酸一丙烯酰胺一苯乙烯磺酸钠)(AA-AM-SSS)高吸水性复合树脂.研究了苯乙烯磺酸钠、高岭土含量、交联荆用量和引发剂用量等对复合树脂的吸水率的影响,并用FT-IR和SEM等表征了复合树脂的结构,用TGA和DSC表征了复合树脂的耐热性.结果表明:引发剂、交联剂和高岭土用量影响高岭土复合树脂的吸水率和保水率.当苯乙烯磺酸钠的质量分数为10%,高岭土的质量分数为10%时,高岭土复合树脂具有较好的性能,平衡吸水率为540g/g.SEM结果表明,高岭土呈颗粒状不规则地分布于树脂中,树脂的表面有许多微小的圆孔.

A high water superabsorbent kaolinite/poly(acrylic acid-co-acrylamide-co-sodium p-styrenesulfonate) was prepared by UV photopolymerization,using N,N-methylene bisacrylamide as crosslinker and 1173 as the photoinitiator.Factors affecting the water absorbency such as amount of kaolinite,crosslinking agent and initiator were systematically studied.FT-IR and SEM were used to characterize the structure of the composite superabsorbent.TGA and DSC were used to characterize thermal stabilities of the composite superabsorbent.The results showed that the composite superabsorbent had good water absorbency of 540g/g when 10%SSS and 10%kaolinite were used.SEM indicated that kaolinite irregularly distributed within the superabsorbent,and the surface of the superabsorbent had many deep and small capillaries.
