摘要
以聚醚多元醇、聚酯多元醇、异佛尔酮二异氰酸酯（IPDI）、二羟甲基丙酸（DMPA）等为原料，采用预聚体自乳化的方法合成脂肪族水性聚氨酯，通过单因素分析法，优化出最佳合成工艺：预聚反应65℃，2h；扩链反应70℃，2h；R值[n（异氰酸酯）：n（羟基）]为1．8～2．4，DMPA用量3．5％～5．5％．整理后，防皱效果良好．
Aliphatic waterborne polyurethane （WPU） was synthesized using polyether polyols, polyester polyols, isopropyl ketone diisocyanate （IPDI） and dimethylol propionic acid （DMPA） as raw materials through pre-polymerization self-emulsion method. The optimal synthetic technology was obtained through single factor method： pre-polymerization process was conducted at 65 ℃ for 2 h, extended chain reaction was per-formed under 70 ℃ for 2 h, R value （the molar ratio of isocyanate and hydroxyl） was 1.8-2.4 and DMPA dosage was 3.5%-5.5%. The finished fabric had good wrinkle resistance.
