Изобретение касаетс пленочного материала на основе сополимера тетрафторэтилена с перфтор-2 (2-фторсульфонилэтокси) - пропилвиниловым эфиром и может быть использовано дл изготовлени ионообменных мембран, фильтров, а также Б электрохимической промышленности дл разделени электрохимических энементов.The invention relates to a film material based on a copolymer of tetrafluoroethylene with perfluoro-2 (2-fluorosulfonylethoxy) -propyl vinyl ether and can be used to manufacture ion-exchange membranes, filters, and B electrochemical industry for the separation of electrochemical elements.
Известен пленочный материал на основе сополимера тетрафторэтилена с перфтор-2 (2-фторсульфонилэтокси ) - п юпилвиниловым эфиром, получаемый прессованием его в формах при температуре и давлении 2000 ат.Known film material based on a copolymer of tetrafluoroethylene with perfluoro-2 (2-fluorosulfonyloxy) -p yupylvinylether, obtained by pressing it in forms at a temperature and pressure of 2000 at.
Цель изобретени - упрощение технологии получени пленочного материала - достигаетс тем, что в сополимер тетрафторэтилена с перфтор-2 (2-фторсульфонилэтокси) - пропилвиниловым эфиром введен фторсодержащий сополимер при соотношении компонентов соответственно 85:15 - 75:25. Получаетс пленочный материал, который далее обрабатываетс раствором NaOH дл превращени SO F-групп в SOjNa.The purpose of the invention is to simplify the technology for the production of the film material by achieving the fluorine-containing copolymer in the copolymer of tetrafluoroethylene with perfluoro-2 (2-fluorosulfonylethoxy) -propyl vinyl ether with a ratio of components of 85:15 - 75:25. A film material is obtained, which is further processed with a solution of NaOH to convert the SO F groups to SOjNa.
ПРИЗЕР I. На вальцах с температурой валков в течение 3-5 мин развальцовывают 20 вес.частей сополимера винилиденфторида с перфтср - (метилвиииловым) эфиром и в него постепенно ввод т 80 вес. частей порошкообразного сополимера тетрафторэтилена с перфтор-2 (2-фторсульфонилэтокси) - пропилвиниловым эфиром до получени однородной массы. Смешение провод т в течение 15-18 мин. В результате получают пленочный материал.SIGNATURE I. On rollers with a roll temperature, for about 3-5 minutes, 20 parts by weight of a copolymer of vinylidene fluoride with perftsr - (methylviiiyl) ether are expanded and 80 wt. Are gradually added to it. parts of powdered copolymer of tetrafluoroethylene with perfluoro-2 (2-fluorosulfonylethoxy) -propyl vinyl ether to obtain a homogeneous mass. Mixing is carried out for 15-18 minutes. The result is a film material.
ПРИМЕР 2. По методике, описанной в примере I, получают пленочный материал с использованием в качестве второго компонента сополимера винилиденфторида с гексафтоопиопиленом . EXAMPLE 2. According to the method described in example I, a film material is prepared using vinylidefluoride-hexafto-biopylene copolymer as the second component.
