中文摘要:
      合成了离子液体甲基丙烯酸二甲氨基乙酯顺丁烯二酸盐(DMAEMA-MA),并作为交联剂应用于2-丙烯酰胺-2-甲基丙烷磺酸(AMPS)和丙烯酰胺(AAm)的交联聚合,制备了水凝胶IC-P(AMPS-co-AAm)。以N,N'-亚甲基双丙烯酰胺(BIS)为非离子交联剂制备了水凝胶BIS-P(AMPS-co-AAm),与IC-P(AMPS-co-AAm)的性能进行了比较。通过SEM发现IC-P(AMPS-co-AAm)具有与BIS-P(AMPS-co-AAm)相似的孔道结构,当DMAEMA-MA的添加量为1.6%时,在水中的溶胀率可以达235.97%,同时电导率达到58.8μS/cm。热重分析(TGA)表明,DMAEMA-MA能提高IC-P(AMPS-co-AAm)的热稳定性。考察了不同DMAEMA-MA含量的IC-P(AMPS-co-AAm)与BIS-P(AMPS-co-AAm)的除锈性能,结果表明,当DMAEMA-MA含量为1.6 wt%时,对锈蚀等级为C级的Q235低碳钢除锈效果可达A级。
英文摘要:
      DMAEMA-MA as a new ionic liquid with unsaturated covalent bonds for both anion and cation was synthesized. Poly(2-acrylamide-2-methylpropane sulfonic acid-co-acrylamide) (IC-P(AMPS-co-AAM)) was prepared by polymerization of acrylamide (AAm) and 2-acrylamide-2-methylpropane sulfonic acid (AMPS) using DMAEMA-MA as the crosslinker. BIS-P(AMPS-co-AAm) was prepared by using N,N'-methylene bisacrylamide (BIS) as a non-ionic crosslinker, and the performance of BIS-P(AMPS-co-AAM) and IC (AMPS-co-AAM) was compared. Similar pore structure was observed by SEM. When the addition of DMAEMA-MA was 1.6%, the swelling rate in water could reach 235.97% and the conductivity reached 58.8 μS/cm. TGA shows that DMAEMA-MA can improve the thermal stability of IC-P(AMPS-co-AAM). The derusting performance of IC-P(AMPS-co-AAM) with different DMAEMA-MA content and BIS-P(AMPS-co-AAM) was investigated. The results showed that the derusting effect of Q235 low carbon steel with rust grade C could reach Grade A when DMAEMA-MA content was 1.6 wt%.
