摘要
将苯酚、甲醛与胺类化合物(如正丙胺、三乙胺、二乙基乙醇胺等)在一定条件下反应,可得到胺基改性的阳离子型酚醛树脂(CPFR);该阳离子型的酚醛树脂与聚氧化乙烯(PEO)共用组成新型的助留体系,能显著提高浆料中细小组分的留着率,增强聚氧化乙烯的助留效果。
A modified phenol-formaldehyde resin containing cationic amine groups (CPFR) was prepared by the reaction of phenol, formaldehyde and amine compounds, for example n-propyl amine, triethyl amine, diethyl ethanol amine and so on. A new retention system comprised of the modified phenol-formaldehyde resin and polyethylene oxide can improve the retention efficiency remarkably.
