Abstract
1. Армированная ионообменная мембрана для электролиза, выполненная в виде пленки из сополимера тетрафторэтилена и сульфированного перфторвинилового эфира, армированной политетрафторэтиленом, распределенным по объему пленки, и снабженной каркасом из сшитого с помощью вулканизующего агента фторкаучука, отличающаяся тем, что, с целью снижения напряжения при использовании мембраны в процессе электролиза, мембрана содержит каркас в поверхностном слое по меньшей мере с одной стороны при толщине слоя до половины общей толщины мембраны.2. Способ получения армированной ионообменной мембраны для электролиза путем формирования пленки из композиции, включающей сополимер тетрафторэтилена и сульфированного перфторвинилового эфира, политетрафторэтилен и фторкаучук, гидролиза пленки и термообработки при 100 - 350С в присутствии вулканизующего агента, отличающийся тем, что перед стадией термообработки по меньшей мере одну поверхность пленки прокалывают вулканизующим агентом на глубину до половины общей толщины пленки.1. Reinforced ion-exchange membrane for electrolysis, made in the form of a film of a copolymer of tetrafluoroethylene and sulfonated perfluorovinyl ether, reinforced with polytetrafluoroethylene, distributed over the volume of the film, and equipped with a frame made of a vulcanizing agent crosslinked with a vulcanizing agent; membrane in the electrolysis process, the membrane contains a frame in the surface layer at least on one side when the layer thickness to half the total thickness of the membrane. A method of obtaining a reinforced ion-exchange membrane for electrolysis by forming a film from a composition comprising a tetrafluoroethylene and sulfonated perfluorovinyl ether copolymer, polytetrafluoroethylene and fluororubber, film hydrolysis and heat treatment at 100 - 350С in the presence of a curing agent, characterized in that at least one surface films are punctured with a vulcanizing agent to a depth of half the total film thickness.
