摘要:以异佛尔酮二异氰酸酯(IPDI)、聚四氢呋喃醚二醇(PTMG)、二羟甲基丁酸(DMBA)、1,4-丁二
醇(BDO)和自制红色蒽醌染料(DYE-R)为原料合成聚氨酯(PU),以甲基丙烯酸羟乙酯(HEMA)为封端
剂制得了双键封端的水性聚氨酯,再采用无皂乳液聚合法与甲基丙烯酸甲酯(MMA)和丙烯酸丁酯(BA)单
体共聚制备了玫红色水性聚氨酯-丙烯酸酯乳液,采用 FTIR、纳米粒度仪、TEM、UV-Vis、TG 对乳液及胶膜进
行了表征。结果表明,随着丙烯酸酯单体用量的增加,乳液粒径增加,当 m(PU)∶m(MMA 与 BA)为 10∶2 时,
乳液的综合性能最好,粒径为 81 nm,稳定性好且有一定耐碱性。该乳液着色效果明显,热迁移率为 3.54%,耐
干、湿摩色牢度为 4~5 级。当该乳液胶膜质量保留率为 50%时,所对应温度为 396.1 ℃。

Abstract: Polyurethane (PU) was synthesized with isophorone diisocyanate (IPDI), polytetrahydrofuran
ether glycol (PTMG), dimethylol butyric acid (DMBA), 1,4-butanediol (BDO) and self-made red
anthraquinone dye (DYE-R), and 2-hydroxyethyl methacrylate (HEMA) was used as end-capping agent to
prepare double-bond terminated waterborne polyurethane. Then rose red waterborne polyurethane-acrylate
emulsion was prepared by soap-free emulsion polymerization with methyl methacrylate (MMA) and butyl
acrylate (BA) monomers. The emulsion was tested and characterized by FTIR, nano-particle size analyzer,
TEM, UV-Vis and TG. The results showed that the particle size of the emulsion increases with the increase
of the amount of acrylate monomer, and when m(PU)∶m(MMA and BA)=10∶2, the emulsion with a
particle size of 81 nm, good stability and certain alkali resistance, exhibited the best overall performance.
Furthermore, the emulsion had obvious coloring effect with a thermal mobility 3.54% and color fastness to
dry and wet rubbing 4~5 grades. When the mass retention rate of the emulsion film was 50%, the
corresponding temperature was 396.1 ℃.
