中文摘要	利用水溶液聚合法合成了聚丙烯酸系高吸水性高保水性树脂,其吸水倍率均在800 g/g以上,且在50 min内吸水饱和。研究了共聚单体和交联剂用量对树脂加压保水能力和恒温保水能力的影响。研究结果表明,树脂恒压放置7 d后保水率均在30%以上,保水能力随丙烯酰胺用量增加先增大后减小,随交联剂MBA用量增加先增大后减小。同时,PAA-AM-AMPS在沙土中恒温50℃时放置7 h后,保水率为75.5%,说明树脂能提高沙土的饱和含水量,有效地改良沙土的保水能力,为沙漠保水提供有效的保水剂。
英文摘要	The SAP (superabsorbent polymer)was synthesized by water solution polymerization.The absorbency rate was above 800 g/g and the saturation point was within 50 min.The effect of the amount of the co-monomers and cross-linking agent on water-retention capacity at constant pressure and temperature was investigated.The results show that the water-retention capacity of the SAP was above 30% after being placed under constant pressure for 7 d.The results also indicate that the waterretention capacity increased at first and then decreased with the increase of the amount of acrylamide and MBA.At the same time,the water-retention rate of the SAP was above’75.5% after being placed at constant temperature 50 ℃ for 7 h,which demonstrate that the SPA can efficiently improve the saturated water content of the sand and the water-retention capacity of the sand and can be used as an excellent water-retention agent in desert area.
