Method for preparing water-soluble polyether-ether-ketone paint

The invention belongs to the field of polyether-ether-ketone materials and particularly discloses a method for preparing a water-soluble polyether-ether-ketone paint. The method comprises the following steps: (1) synthesis of polyether-ether-ketone; (2) preparation of a dispersion liquid; (3) preparation of a water solution; (4) desolvation; and (5) coating and cross-linking. The prepared water-soluble polyether-ether-ketone paint can be kept stable in a water dispersion system for a long time, the viscosity of a coating system can be adjusted through a pure water phase without adding any assistant, the coating thickness can be flexibly adjusted according to requirements of different work conditions and environments during the use, a 'touch dry' coating can be obtained within a relativelyshort time, dust adsorption and defect repair are reduced. 本发明属于属于聚醚醚酮材料领域，具体公开种水溶性聚醚醚酮涂料的制备方法，包括以下步骤：(1)聚醚醚酮合成，(2)分散液制备，(3)水溶液制备，(4)去溶剂，(5)涂装、交联。本发明制备得到水溶性聚醚醚酮涂料，可以长期在水分散体系保持稳定，涂料体系粘度可以通过单纯的水相进行调节，无需添加任何助剂，在使用过程中可以根据不同工况和环境的
