摘　　要：采用高温快速的水溶液聚合方法合成了高岭土/聚丙烯酸高吸水性复合材料,探讨了复合材料合成过程中各种因素,如引发剂用量、交联剂用量、中和度、高岭土超细粉用量等对复合材料吸水倍数的影响,还对该高吸水性复合材料进行表面亲水改性研究,结果表明表面亲水改性有利于提高复合材料的吸水速率。By high temperature rapid-induced solvent polymerization reaction between kaolin ultrafine powder and acrylic acid, the superabsorbent composite was synthesized. The relationship between the absorbency of the superabsorbent eomtosite and the reaction condition was investigated, such as the amount of initiator and crosslinking agent, the degree of neutralization, and the amount of kaolin. The surface modification of the composite was investigated. The results showed the surfaoe modification would improve the absorbing rate of the composite.
