Summary: | The invention discloses a preparing method of an anion-exchange membrane. The method comprises the following steps of (1) membrane liquid preparation: two kinds of monomers including methacryloyloxyethyl trimethyl ammonium chloride and dimethyl amino ethyl methacrylate are mixed with crosslinking agents, initiators and organic solvents to be prepared into uniform solution for obtaining membrane liquid; (2) membrane liquid adsorption: non-woven fabrics are used as substrates, the substrates are soaked into the membrane liquid prepared in the first step, after the sufficient soaking, the substrates are taken out and are placed between two polyethylene terephthalate thin films, bubbles possibly existing between the substrates and the thin films are eliminated, so the substrates and the two thin films form a composite body; (3) heat polymerization treatment: the composite body prepared in the second step is placed under the temperature condition being 60 DEG C to 140 DEG C, so the polymerization reaction is initi |
