摘    要:采用多种分析仪器和手段包括红外光谱,凝胶色谱,色谱-质谱联用技术,核磁共振波谱等,探讨了水性聚氨酯乳液中的溶剂和树脂成分的定性定量分析方法。对组成水性聚氨酯乳液中的低聚物多元醇种类,异氰酸酯种类,扩链剂,成盐剂,水和有机溶剂,乳化剂等进行了全分析,同时用凝胶色谱对树脂进行分子量及其分布测定。分析结果表明该水性聚氨酯乳液应为羧酸型阴离子聚氨酯乳液,是由聚酯二元醇,异佛尔酮二异氰酸酯及含羧基的二羟基化合物(DMPA)生成聚氨酯预聚体,然后用丙酮溶解预聚体后在水中乳化形成的。

关 键 词:水性聚氨酯乳液  溶剂和树脂成分  定性定量分析

Abstract:Qualitative and quantitative analysis of the ingredients of Water-borne polyurethane emulsion which usually consists of polyols,diisocyanate,chain extender,salifying agent water and organic solvents and so on,was discussed by multi-analytic techniques such as IR,GPC,GC/LC/MS and NMR.Molecular weight and its distribution were determined by gel permeation chromatogram.The experimental results showed that this kind of water-borne PU was carboxylate anionic type emulsion.Isophorone diisocyanate(IPDI),polyester ...
Keywords:water-borne polyurethane(PU) emulsions  solvents and components of PU  qualitative and quantitative analysis
