| 摘 要： | 采用烯丙基聚乙二醇单醚APEO10为原料制备了大分子单体磺酸盐封端聚醚APES10和羧酸盐封端聚醚APEC10并分别与小分子单体丙烯酸AA聚合生成两种聚羧酸类阻垢剂AA/APES10和AA/APEC10,用红外光谱、核磁共振对其结构进行了表征。实验确定了聚合反应单体最佳质量比为m(APES10):m(AA)=1:1,m(APEC10):m(AA)=2:3。通过静态阻垢实验对比了两种聚合物的阻磷酸钙垢性能。结果表明,合成的两种阻垢剂AA/APES10和AA/APEC10在临界值6 mg·L-1时阻磷酸钙垢率分别为92%、100%,但羧酸盐封端聚醚大单体合成的阻垢剂AA/APEC10阻磷酸钙垢能力优于磺酸盐封端聚醚大单体合成的阻垢剂,且聚合物AA/APEC10只含碳、氢、氧、钠4种元素,无氮、磷污染,可以充当循环水用环保型阻磷酸钙垢阻垢剂。

| Abstract: | Capped polyether macromonomers APES10 and APEC10 were synthesized from allyl polyethylene glycol sole ether APEO10,and their polycarboxylic acid type copolymers AA/APES10,AA/APEC10 as antiscalants were prepared from small molecule monomers acrylic acid AA.The products were characterized by FT-IR and 1H NMR and the performance of their copolymers of calcium phosphate inhibition was evaluated by the static scale-inhibiting method.The studies indicated that when mass ratio of APES10 to AA was 1:1,APEC10 to AA was 2:3,both AA/APEC10 and AA/APES10 had much better ability to inhibit the precipitation of calcium phosphate than other mass ratios.It was also shown that both AA/APEC10 and AA/APES10 had superior ability to inhibit the precipitation of calcium phosphate when the dosage was 6 mg·L-1,approximately showing 100%,92% inhibition,respectively. While compared to that of AA/APES10,AA/APEC10 had superior ability to control calcium-phosphate deposition.Furthermore,the synthesized AA/APEC10 is an environmentally friendly antiscalant,only containing four elements of carbon (C),hydrogen (H),oxygen (O),sodium (Na),without phosphorous (P)and nitrogen (N).AA/APEC10 is an excellent performance non-phosphorus inhibitor for calcium phosphate scaling in industrial recycling water systems. |
