摘  要:
以新疆哈密褐煤为原料提取腐植酸,以丙烯酸和丙烯酰胺为单体,采用溶液聚合法,合成聚丙烯酸钠-丙烯酰胺(PSA-AM)高吸水性树脂。在PSA-AM的基础上加入粉煤灰和腐植酸,合成一种加粉煤灰和腐植酸的高吸水性树脂。合成的吸水性树脂有较好的保水性和吸水性,能促进植物的生长,改善土壤的理化性质,同时能降低树脂的合成成本,有较好的经济和利用价值。

摘  要:
Using humic acid extracted from Sinkiang Hami brown coal as raw material,and acrylic acid and acrylamide as monomer,PSA-AM polymer was synthesized by the method of solution copolymerization.Based on PSA-AM,a new super absorbent polymer was synthesized through adding humic acid and fly ash.The new polymer had well capacity of retaining and adsorbing water,and could promote plant growth,and improve soil physi-chemical properties.Meantime,its cost was lower relatively.Thus,the new polymer had a good economic and use value.
