The invention relates to a high-oxygen-permeability fluorine-containing phosphoric acid-sulfonic acid resin dispersion liquid and a preparation method thereof. Perfluorosulfonic acid phosphonic acid resin is composed of a fluorine-containing olefin unit, a perfluorovinyl ether phosphonic acid unit, a perfluorovinyl phosphonic acid unit and a sulfonyl fluoride-containing perfluoroheterocyclic olefin ether unit. The molar content percentage of each polymerization unit is as follows: the fluorine-containing olefin unit accounts for 40-80%, the perfluorovinyl ether phosphonic acid unit accounts for 5-35%, the perfluoroethylene phosphonic acid unit accounts for 5-35%, and the sulfuryl fluoride-containing perfluoro heterocyclic olefin ether unit accounts for 5-50%. The prepared novel perfluorinated ion resin dispersion liquid is uniform in dispersion, the micelle particle size is 145-195 nm, no white incompletely-dissolved resin residue exists, the storage stability is good, and the novel perfluorinated ion resin d
