摘要
利用胺类化合物(如正丙胺、三乙胺、二乙基乙醇胺等)与苯酚和甲醛反应,得到胺基改性的带阳离子性的酚醛树脂(PFR);该阳离子性的酚醛树脂与聚氧化乙烯(PEO)共用组成新型的助留体系,能显著提高纸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 is achieved by the reaction of phenol, formaldehyde and amine compounds, for example, n - propyl amine, triethyl amine, diethyl ethanol amine and so on. The new system comprised of modified phenol - formaldehyde and polyethylene oxide can improve the retention greatly.
