摘要 以水为溶剂,丙烯酸(AA)和烯丙氧基聚醚羧酸钠(APEX)为单体,合成了一种新型的无磷聚醚共聚物(APEX/AA)。 通过红外光谱、热重分析及凝胶渗透色谱对聚合物进行了表征。 通过静态法评价了APEX/AA用量、溶液钙离子浓度、pH值、温度对APEX/AA阻磷酸钙垢率的影响。 结果表明,聚合物APEX/AA有良好的热稳定性(至350 ℃才明显失重),相对分子质量分布可控(PDI=1.41~1.88)。 APEX/AA在用量6 mg/L时阻磷酸钙垢率达到100%,APEX/AA阻磷酸钙垢效果优于羟基亚乙基二膦酸、丙烯酸/丙烯酸羟丙酯、2-膦酸丁烷-1,2,4-三羧酸等商业阻垢剂,适用于高钙(Ca2+浓度200~2000 mg/L)、高pH值(7.5~11.0)和高温(75~95 ℃)水质,是一种工业循环水系统中性能优良的阻磷酸钙垢无磷阻垢剂。

Abstract:A new type of polyether copolymer—allyloxy polyether carboxylic acid sodium/acrylic acid(APEX/AA) was synthesized using water as solvent and APEX and AA as monomers. Polymer APEX/AA was characterized by infrared spectroscopy, thermogravimetric analysis and gel permeation chromatography. The dosage of APEX/AA, calcium ion concentration in solution, pH and temperature were evaluated on phosphate calcium scale inhibition efficiency through static method. The results show that the polymer APEX/AA has good thermal stability at temperature above 350 ℃, and its relative molecular mass distribution is controllable(PDI=1.41~1.88). The phosphate calcium scale inhibition efficiency of APEX/AA reached 100% when a concentration of 6 mg/L aqueous system was used. The results show that APEX/AA is suitable for water with a high calcium ion concentration(200~2000 mg/L), high pH(7.5~11.0) and high temperature(75~95 ℃). The scale inhibition effect of APEX/AA is superior to that of commercial calcium phosphate scale inhibitors such as 1-hydroxyethylidine-1,1-diphosphonic acid(HEDP), hydroxypropyl acrylate/acrylic acid(T-225) and 2-phosphonobutane-1,2,4-tricarboxylic acid(PBTCA), indicating that APEX/AA is an excellent non-phosphorus phosphate calcium scale inhibitor in the industrial circulating water systems.
