一种利用超声波辐照制备高吸水性树脂的方法
摘要：
本发明公开了一种利用超声波辐照制备高吸水性树脂的方法，其采用超声波辐照聚合技术在水相体系中反应制备高吸水性树脂。具体通过以下步骤实现：1．对玉米秸秆的改性处理；2．在超声波辐照条件下进行高吸水性树脂的聚合。本发明将超声波辐照技术应用于吸水树脂制备，大大缩短了反应时间，制备工艺简单，无需氮气保护；所制得的产品吸水能力强。所得产品可用于医疗用品、个人卫生用品及农用保水缓释剂等。本发明的优点在于：制备的吸水树脂结构均匀，单体转化率高，且制备工艺简单、成本低廉。？
摘要（英）：

The invention discloses a method for preparing high-water-absorptivity resin by using ultrasonic irradiation. Reaction is carried out in a water-phase system to prepare the high-water-absorptivity resin by using the ultrasonic irradiation polymerization technology. The method comprises the following steps: 1, modifying maize straws; and 2, polymerizing the high-water-absorptivity resin under the condition of ultrasonic irradiation. The invention applies the ultrasonic irradiation technique to the preparation of water-absorbing resin, thereby greatly shortening the reaction time and having the advantages of greatly reduced reaction time, simple preparation technique and no need of nitrogen protection; and the product has high water absorptivity. The product can be used in medical supplies, personal hygienic products, agricultural water-retention slow-release agents and the like. The invention has the advantages of uniform structure of water-absorbing resin, high monomer conversion rate, simple preparation technique and low cost.
