摘要:

以乙烯基异丁醚(VIBE)、丙烯酸(AA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)为单体,合成了单体比例不同的系列聚合物。采用静态阻垢法评价了其对碳酸钙、磷酸钙的阻垢性能和对氧化铁以及锌盐的分散性能。结果发现,含醚基磺酸基聚合物具有临界值效应,对碳酸钙的阻垢作用,对氧化铁、锌盐的分散作用要优于AA/HPA/AMPS聚合物,其中醚基含量越高,其对碳酸钙垢的阻垢作用和对锌盐的分散作用越好,但对磷酸钙垢的抑制作用要比AA/HPA/AMPS聚合物低。

关键词: 共聚物, 阻垢, 分散

Abstract:

A series of copolymers containing vinyl isobutyl ether (VIBE), acrylic acid(AA), 2- acrylamido- 2- methyl propane sulfonic acid(AMPS) have been synthesized. The effect of using static inhibition on the inhibition performances of CaCO3, Ca3(PO4)2, Fe2O3 and zinc salt are evaluated. It is found that the copolymers containing ether and sulfonic group have threshold effect. The inhibition effect of VIBE/AA/AMPS copolymer on CaCO3, the dispersion effect on Fe2O3 and zinc salt are better than AA/HPA/AMPS copolymer. The higher content of ether group in VIBE/AA/AMPS copolymer, the better inhibition effect on CaCO3 and zinc salt. But the inhibition effect of VIBE/AA/AMPS copolymer on Ca3(PO4)2 is worse than AA/HPA/AMPS copolymer.

Key words: copolymer, scale inhibition, dispersion
