摘要/Abstract

摘要： 将硫酸盐纸浆废液浓缩后,100%用作生产木材胶粘剂的原料.对废液中木素进行活化处理,用酚醛树脂、PAPI增强废液胶的效果.结果表明,在废液中加入甲醛后,可提高废液中木素的反应活性;用30%甲阶酚醛树脂或20%PAPI作增强剂,可使废液混合胶代替纯酚醛树脂生产Ⅰ类胶合板;原料成本比纯酚醛树脂分别降低了55.5%和49.0%.该法充分利用了废液中的有机物资源,减少了环境污染,具有较好的经济、社会和生态效益.文中还运用红外光谱分析了废液制胶粘剂方法的可行性.

Abstract: In this paper,one hundred percent of condensed sulfate paper pulp waste liquid was used as the raw material of adhesive,and the activation of its lignin as well as the improving effects of phenol formaldehyde resin and polyfunctional aqueous polymer isocyanate (PAPI) were studied.The results showed that adding formaldehyde to the waste liquid could increase the reactivity of contained lignin,and adding 30% phenol formaldehyde resin or 20% PAPI could make the waste liquid in place of pure phenol formaldehyde resin for producing classⅠplywood.Furthermore,the cost could be reduced by 55.5% and 49.0%,respectively,in comparing with pure phenol formaldehyde resin.This approach fully used the organic resources in paper pulp waste liquid,reduced environment pollution at the same time,and had unexceptionable economic,social and ecological benefits.The feasibility of preparing adhesives from paper pulp waste liquid was also analyzed by infrared spectrum.

Key words: Sulfate paper pulp waste liquid, Lignin, Phenol formaldehyde resin, Polyfunctional aqueous polymer isocyanate, Infrared spectrum analysis
