| description | An ion-conducting membrane used in the chlor-alkali industry and a preparation method thereof are disclosed. The ion-conducting membrane includes a perfluorinated ion exchange resin base film, a porous reinforcing material and a perfluorinated ion exchange resin micro-particle surface layer. The perfluorinated ion exchange resin micro-particles are a mixture of one or two of perfluorocarboxylic acid resin micro-particles and perfluorosulfonic acid carboxylic acid copolymer resin micro-particles with perfluorosulfonic acid resin micro-particles. A mass percentage of perfluorosulfonic acid resin micro-particles in the mixture is 50-95%. The surface layer of the present invention has good compatibility and adhesion, and maintains a good degassing effect during the entire lifespan of the ion-conducting membrane. The present invention is used in the chlor-alkali industry, stably and effectively processes alkali metal chloride solutions having a wide range concentration and suitable for operating in a zero polar distance electrolytic cell under novel high current density conditions. |
