The invention belongs to the technical field of fluorine-containing high polymer materials, and particularly relates to a multi-component copolymerized ion exchange resin dispersion liquid as well as a preparation method and application thereof. The dispersion liquid comprises multi-component copolymerized ion exchange resin, an organic solvent and water. The multicomponent copolymerized ion exchange resin dispersion liquid is uniform in dispersion, free of white incompletely dissolved resin residues and good in storage stability, and the proton exchange membrane prepared from the dispersion liquid has high chemical stability and high ion exchange capacity. 本发明属于含氟高分子材料的技术领域，具体的涉及一种多元共聚离子交换树脂分散液及其制备方法和应用。所述分散液包括多元共聚离子交换树脂、有机溶剂和水。该多元共聚离子交换树脂分散液分散均匀，无白色未完全溶解的树脂残留，存储稳定性好，且由该分散液制得的质子交换膜具有高的化学稳定性、高的离子交换容量。
