摘要/Abstract

摘要：

考察了一种丙烯酸-聚醚改性丙烯酸酯共聚物HS-C的结构特征、聚合物性能（螯合性、抗沉积性）以及表面活性（表面张力、临界胶束浓度、润湿性、乳化性、起泡性和去污力）。并分别对比了HS-C与常用螯合剂、抗再沉积剂以及表面活性剂在不同方面的性能。结果表明，HS-C的螯合值为554.70 mg/g，其螯合性能优于EDTA·4Na及GLDA·4Na，但略低于未改性的丙烯酸盐聚合物PM；其抗炭黑沉积性能与市售抗再沉积剂SRP接近，而PM无抗炭黑沉积作用。在表面活性方面，HS-C的临界胶束浓度和平衡表面张力分别为0.005%和41.85 mN/m；其润湿性能和泡沫性能比LAS、AEO-9、AES相对差，但乳化能力比低分子表面活性剂更好；HS-C具有比LAS更加优越的去污性能，与LAS、AEO-9、AES复配时存在协同增效去污的作用。

Abstract:

An acrylic copolymer modified with surface active groups （HS-C） was studied. Its structural characteristics, polymer properties （chelation and anti-deposition） and surface activity （surface tension, critical micelle concentration, wettability, emulsification, foaming and detergency） were investigated. The performance of HS-C was compared with that of commonly used chelating agents, anti-redeposition agents and surfactants, respectively. The results of FT-IR showed that the main structure of HS-C was similar to that of unmodified sodium polyacrylate （PM）, but with more unsaturated bonds and alcohol and/or ether groups. The experimental results showed that the chelation value of HS-C was 554.70 mg/g, which was higher than that of EDTA·4Na and GLDA·4Na but slightly lower than that of PM. Its anti-deposition performance to carbon black was close to that of commercially available anti-redeposition agent SRP, whereas PM had no anti-deposition effect to carbon black. The critical micelle concentration and equilibrium surface tension of HS-C were 0.005% and 41.85 mN/m, respectively. Its wetting and foaming properties were relatively poorer than those of LAS, AEO-9 and AES, but its emulsifying ability was better than that of low-molecular-weight surfactants. HS-C had detergency superior to LAS, and there was synergistic effect when combined with LAS, AEO-9 and AES.
