摘要

以丙烯酸、丙烯酰胺和羧甲基纤维素(CMC)为原料,加入改性纳米TiO2颗粒,采用反相悬浮聚合法制备光/生物双降解纳米TiO2/CMC基高吸水树脂。采用傅里叶变换红外光谱仪、扫描电子显微镜和X射线衍射仪对高吸水树脂进行了表征并分析了其结构。研究了引发剂用量、交联剂用量和油水(环己烷、水溶液)体积比对高吸水树脂性能的影响。在引发剂用量为0.85%(质量分数),交联剂用量为0.08%(质量分数),油水体积比为4∶1条件下,纳米TiO2/CMC基高吸水树脂吸蒸馏水倍率为838.3g/g,吸0.9%生理盐水倍率为90.3g/g,在土壤中98d降解率达28.72%,紫外光照射下降解率在48h内达到27.78%,说明制备的高吸水树脂具备较强的生物和光降解能力,有望应用于农林业中作物的保水保肥。

Abstract

Nano-TiO2/CMC superabsorbent polymer was prepared by inverse suspension polymerization method which AA,AM and carboxymethyl cellulose (CMC) were used as raw materials,and then the superabsorbent polymer was obtained with adding the nano-titanium dioxide particles.The structure of product was characterized by fourier transform infrared absorption spectroscopy,scanning electron microscopy and X-ray diffraction.The optimized parameters for superabsorbent production were as follows:the initiator dosage was 0.85%,the crosslinking agent dosage was 0.08% and the ratio of oil to water was 4∶1.Under this condition,the absorbency of superabsorbent polymer to distilled water and saline water (0.9%) was 838.3g/g and 90.3g/g,respectively.The soil degradation rate reached 28.72% in three months,and the UV degradation rate reached 27.78% in 48h.The results inferred that nano-TiO2/CMC superabsorbent polymer had strong biological and optical degradation ability that can be applied to the water and fertilizer conservation of crops in agriculture and forestry.
