以异佛尔酮二异氰酸酯(IPDI)与聚醚(N210)为原料，采用自制羟丙基封端聚硅氧烷(HP-PDMS)替代部分聚醚(N210)，制备羟丙基封端聚硅氧烷改性水性聚氨酯乳液，并用于涤纶织物涂层整理.研究改性剂HP-PDMS用量对乳液及胶膜性能的影响，测试涂层织物的应用性能.结果表明：随着HP-PDMS用量的增加，乳液粒径变大，稳定性变差，胶膜水接触角变大，吸水率变小.HP-PDMS用量为6%时，乳液稳定，胶膜水接触角为106.2°，吸水率为32.49%.与未改性的聚氨酯涂层织物相比，改性聚氨酯涂层织物静水压、柔软度均有所提高；与聚醚型聚硅氧烷改性水性聚氨酯涂层织物相比，羟丙基封端聚硅氧烷改性水性聚氨酯涂层织物的静水压和接触角均有所提高，尤其接触角提高显著，达到136.1°.

The waterborne polyurethane emulsion modified with hydroxypropyl polysiloxane (HP- PDMS) was prepared with isophorone di socyanate (IPDI) and polyether (N210) as raw materials, and HP- PDMS in?stead of part of N210, and the modified polyurethane was applied to coat the polyester fabric. The effect of the dosage of HP- PDMS on the properties of emulsion and its film was investigated, and the application prop?erties of the coated fabrics were tested. The results showed that as the dosage of HP- PDMS increased, the particle size of the emulsion increased, the stability of the emulsion decreased, the water contact angle of the film increased, water absorption rate of the film decreased; when the dosage of HP- PDMS was 6%, the sta?bility of the emulsion was good, the water contact angle of the film was 106.2° and the water absorption of the film was 32.49%. Compared with the unmodified waterborne polyurethane coated polyester fabric, the soft?ness and the hydrostatic pressure of the fabric coated with modified waterborne polyurethane were improved. Compared with fabric coated with polyether- polysiloxane modified waterborne polyurethane, the hydrostatic pressure and the water contact angle of the fabric coated with waterborne polyurethane emulsion modified with hydroxypropyl polysiloxane was improved, especial y water contact angle increased significantly, could reached 136.1°.
