摘要

传统的双组分水性聚氨酯(2K WPU)耐水性较低,限制了其在广泛领域的应用。本研究以氟改性丙烯酸酯乳液为羟基组分,亲水改性多异氰酸酯为固化剂,成功制备了氟改性 2K 水性聚氨酯薄膜(2K-WFPUs)。傅立叶变换红外光谱、扫描电子显微镜和 X 射线光电子能谱分析表明,六氟丁基丙烯酸酯(HFBA)被成功引入到 2K-WFPU 中。研究了 HFBA 含量对 2K-WFPU 表面、热稳定性、耐水性、机械和应用性能的影响。与未改性薄膜相比,随着 HFBA 含量从 0% 增加到 8%,2K-WFPU 的静态水接触角从 66°增加到 92°,表面自由能从 42.7 mJ m-2 降低到 28.4 mJ m-2,吸水率从 15.9% 降低到 9.9%。热重分析表明,2K-WFPU 的热稳定性显著提高。同时,添加 HFBA 不会削弱 2K-WFPU 的抗冲击性、柔韧性和粘附性,并保持了最高水平。氟改性 2K WPU 涂料有望应用于木制家具和汽车涂装。

Preparation and application of fluorine-containing acrylate emulsion in two-component waterborne polyurethane coatings

Traditional two-component waterborne polyurethane (2K WPU) has low water resistance, which limits its application in the wide field. In this work, fluorine-modified 2K WPU films (2K-WFPUs) were successfully prepared using a fluorine-modified acrylate emulsion as hydroxyl component and a hydrophilically modified polyisocyanate as curing agent. Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray photoelectron spectroscopy analysis indicate that hexafluorobutyl acrylate (HFBA) was successfully introduced into the 2K-WFPUs. The effects of HFBA content on the surface, thermal stability, water resistance, mechanical, and application properties of 2K-WFPUs were investigated. Compared with the unmodified film, with the increase in HFBA level from 0 to 8%, the static water contact angle of 2K-WFPUs increased from 66° to 92°, the surface-free energy decreased from 42.7 to 28.4 mJ m−2, the water absorption reduced from 15.9 to 9.9%. Thermogravimetric analysis shows that the thermal stabilities of 2K-WFPUs were improved remarkably. Meanwhile, adding HFBA did not weaken the impact resistance, flexibility, and adhesion of 2K-WFPUs and maintained the highest level. The fluorine-modified 2K WPU coatings have potential application in wood furniture and automotive finishing.
