摘要
苯酚、甲醛 (或酚醛树脂 )与胺类化合物 (如正丙胺、二乙基乙醇胺、三乙胺等 )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 。
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 remarkably.
