淀粉／AMPS／DMC高吸水树脂的合成及其吸水保水性能研究
Synthesis of starch/AMPS/DMC super absorbent resin and its properties of water absorbent and retention
摘要
Abstract
The superabsorbent was carried out by aqueous solution polymerization,with 2-acrylamido-2-methyl propanesulfonic acid ( AMPS) and methacryloyloxyethyl trimethyl ammonium chloride ( DMC) as raw materials,( NH4 ) 2 S2 O8 as initiator and MBAM as crosslinking agent.The structure of the super absorbent polymer was characterized by IR and SEM.It was investigated that the effects of the ratio of m( AMPS) and m( DMC) ,the pH value and the amount of starch,initiator and crosslinker on absorbency in distilled water and salt water.The results showed that under optimal conditions the resin can absorb 698 times in distilled water and 86 times in salt water with saline concentration of 0.9%.Simultaneously,studying on the water retention properties of the soil with the resin, the results indicated that the water retention property was greatly raised by adding the starch/AMPS/DMC superabsorbent,and when the resin in an amount of 0. 25 g/50 g, the soil water retention was postponed, and the saturated water content of different soil improved 4.02~5.73 times in water and 1.70~2.04 times in salt water with saline concentration of 0.9%.关键词
