Sun-proof and waterproof ink and preparation method thereof

The invention provides a sun-proof and waterproof ink and a preparation method thereof. A SiO2/fluorine-containing polyacrylate composite emulsion is used as a binder of the ink, SiO2 is good in chemical stability and excellent in ultraviolet shielding capability, and the sun-proof performance of the ink can be enhanced; the fluorine-containing polymer has good hydrophobicity so that the waterproof capability of the ink can be improved; on the basis, the invention provides the water-based ink formula and the preparation method thereof, the components of the ink are well compounded, the emission of VOCs in the production and use process is low, and the ink has broad market prospects. 本发明提供一种耐晒防水的油墨及其制备方法，用SiO/含氟聚丙烯酸酯复合乳液作为油墨的连结料，SiO化学稳定性好，具有优良的紫外屏蔽能力，能够增强油墨的耐晒性能；含氟聚合物具有很好的憎水性能，可以增加油墨的防水能力；在此基础上提供一种水性油墨配方及其制备方法，油墨各组分复配良好，生产使用过程中VOCs排放低，具有广阔色市场前景。
