Description

一种具有荷叶效应的生物基亮光水性清面漆
技术领域
本发明涉及一种自交联的生物基亮光水性清面漆，其表面能形成荷叶效应，属于水性功能涂料技术领域。
背景技术
涂料是一种材料，这种材料可以用不同的施工工艺涂覆在物件表面，形成粘附牢固、具有一定强度、连续的固态薄膜，使被涂物体的表面与环境介质相隔离，从而对被涂物体起到的保护和装饰的作用。根据涂膜的反光性，涂料分为无光涂料、平光涂料、亚光涂料、亮光涂料等。
油性木器涂料以各种有机溶剂如苯类、酮类、酯类、醚类等为分散介质，这些溶剂容易挥发，有刺激性气味且对人体存在着不同程度的毒害，在生产过程、应用过程及干燥过程中不断挥发到空气中或被人体吸收，严重地破坏环境，伤害人体健康。
中国专利CN103333598A公开了一种具有高硬度、高光泽木器用亮光白面漆，其使用聚酯树脂DP315加上进口钛白粉等配成亮光白面漆为甲组分，将正丁酯、HX-90B等配制成乙组分，以正丁酯、丙二醇甲醚醋酸酯、碳酸二甲酯、EGDA和二甲苯配制成施工时的稀释剂等配成丙组分，将甲、乙、丙组分混合配制成具有高硬度、高光泽木器用亮光白面漆；其含有机溶剂较多，不符合“绿色”发展。
中国专利CN102363705A公开了水性单组份全亮光清面漆及其制备方法，其采用聚丙烯酸改性聚氨酯和水性聚氨酯分散体经过自身化学交联发应，再混合润湿剂、流平剂、消泡剂、成膜助剂、水组成的一种涂料，其最大的特点在于其性能除具有溶剂型的性能外，还包括环保、低碳、优异的光泽、优异的耐污染性并能解决常规水性漆与其他水性体系相容性不好问题的水性单组份全亮光清面漆；但其漆膜表面张力大，易被污染物污染，时间越长光泽越低，持久性较差。
我国水性木器涂料起步较晚，整体技术水平相对落后，应用也有局限性，与油性木器涂料的性能相比，水性木器涂又普遍存在耐水性能不好、光泽低等问题，因此，研发一种疏水水性能好、光泽高的水性木器清面漆，对于促进木器涂料的全面水性化、推动木器涂料的转型升级，具有十分重要的经济效益与社会价值。
发明内容
本发明所述的具有荷叶效应的生物基亮光水性清面漆，采用一种生物基氟改性水性聚氨酯树脂，包含聚氨酯软硬链段、多元胺扩链段以及氟封端基团和蓖麻油封端基团；该树脂不仅具有聚氨酯硬度大、耐腐蚀、柔韧性好等性能，还具有氟原子的低表面和化学惰性，以及蓖麻油原料可再生、成本低、提高光泽等特点；因蓖麻油中含有双键，能在氧气存在下发生自交联固化，从而提高漆膜硬度。
氟原子半径小且具有很强的电负性，以及独特的低表面张力、低表面自由能和低摩擦系数，这赋予涂层表面具有荷叶效应。
