| 中文摘要: |
| 目的 采用传统涂料印花工艺时，由于合成树脂和助剂的石油基原料的占比超过50%，对不可再生石化资源的高度依赖加剧了能源危机和环境污染。相比之下，生物基原料具有环保、可再生、低VOC排放等优势，因此以生物基原料制备的水性聚氨酯(WPU)有望从源头降低涂料印花行业的碳足迹，推动行业绿色转型。方法 以生物基聚三亚甲基醚二醇(PO3G 1000)、聚碳酸酯二醇(PCDL 2000)、1,5-五亚甲基二异氰酸酯(PDI)为主要原料，以异山梨醇(IS)为扩链剂，采用预聚体分散法制备一系列生物基WPU乳液，并进行性能测试。结果 随着IS含量的增加，固化膜的热稳定性、力学性能和水接触角都显著提升，当IS的用量(质量分数)为2.6%时，其综合性能最优。结论 当IS的用量(质量分数)为2.6%时，固化膜的水接触角从70°提高至80.2°，最大热分解温度从372.16 ℃提升至402 ℃，布板皂洗牢度大幅提升，满足涂料印花领域的应用要求。该研究为生物基水性聚氨酯在印花领域的应用提供了理论支撑，助力涂料印花行业绿色转型升级。 |

| In traditional coating printing processes, petroleum-based raw materials account for over 50% of synthetic resins and additives, exacerbating energy crises and environmental pollution due to high dependence on non-renewable fossil resources. In contrast, bio-based raw materials offer advantages such as environmental friendliness, renewability, and low VOC emissions. Therefore, the work aims to adopt bio-based raw materials to prepare water-based polyurethane (WPU), thus reducing the carbon footprint of the coating printing industry from the source and driving its green transformation. With bio-based poly(trimethylene ether) diol (PO3G 1000), polycarbonate diol (PCDL 2000), and 1,5-pentamethylene diisocyanate (PDI) as primary raw materials and isosorbide (IS) as a chain extender, a series of bio-based WPU emulsions were prepared by the prepolymer dispersion method and tested for properties. As the IS content increased, the thermal stability, mechanical properties, and water contact angle of the cured film significantly improved. When the IS content reached 2.6%, the overall performance was optimal. When the IS content is 2.6%, the water contact angle of the cured film increases from 70° to 80.2°, the maximum thermal decomposition temperature rises from 372.16 ℃ to 402 ℃, and the fabric plate soap wash fastness significantly improves, meeting the application requirements of the coating printing industry. This study provides theoretical support for the application of bio-based waterborne polyurethane in the printing field, contributing to the green transformation and upgrading of the coating printing industry. |
