摘要

以芦荟 (Aloe)、丙烯酸 (AA)为主要原料采用接枝共聚法合成了环境友好型高吸水树脂 (P(AA-

-Aloe))。通过红外光谱 (FTIR)、扫描电子显微镜 (SEM)等对高吸水树脂结构、形貌等进行了分析。探究了不同合成条件对高吸水树脂吸水(盐)性 (蒸馏水1194.2 g/g

自来水339.8 g/g

0.9 wt% NaCl 103.3 g/g)的影响。同时在pH=7时溶胀性最好

反复溶胀5次溶胀率仍达70.8%

在80 ℃时经过12 h后

其保水率达31.67%。该高吸水树脂能够应用于干旱沙漠地区保水固沙、农林园艺、农业种植保水等方面。

Abstract

Environmentally friendly and highly absorbent resin (P(AA-

-Aloe)) was synthesized by grafting copolymerization of Aloe and acrylic acid (AA). The structure and morphology of the superabsorbent resin were charicterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The effects of different synthetic conditions on the water absorption (salt) of the highly absorbent resin (distilled water 1194.2 g/g

tap water 339.8 g/g

0.9 wt% NaCl 103.3 g/g) were investigated. Meanwhile

the swelling property was the best when pH=7

and the swelling rate was 70.8% after five times of repeated swelling

the water retention rate reached 31.67% after 12 h at 80 ℃. The Aloe-based superabsorbent resin can be applied to water retention and sand fixation in arid desert areas

agriculture and forestry horticulture

water retention in agricultural planting and so on.
