摘要
高吸水性树脂凭借其优越的吸水和保水性能,已成为国民经济各个领域中不可或缺的重要材料,但传统的高吸水性树脂吸水速度慢、耐盐性差、凝胶强度低等问题限制了其发展。针对高吸水性树脂日益明显的缺陷,科研人员开始着手研究合成和加工新方法,以降低树脂生产成本低,提高树脂生物降解性、凝胶强度、吸水性和耐盐性等性能,从而推广产品使用范围。本文基于近年来该领域的研究,概括了高吸水性树脂目前主要存在的性能缺陷,并提出相应的改性策略来提高吸水性树脂的综合性能。
The superabsorbent resin has become an indispensable material in all areas of the national economy by virtue of superior water absorption and water retention. However, the slow water absorption, poor salt tolerance, low gel strength and other issues of traditional super absorbent resin have restricted its development. In view of the increasingly obvious defects in the traditional superabsorbent resin, researchers have begun to study the synthesis and processing new methods of reducing resin production cost, improving biodegradability of resin, gel strength, water absorption and salt tolerance, so as to promote the use of products. Based on the recent research in this field, this paper summarizes the current performance defects of the superabsorbent resin, and puts forward the corresponding modification strategy to improve the comprehensive performance of the water absorbent resin.
