Abstract
FIELD: chemical engineering. SUBSTANCE: claimed composition comprises savilene, xylene and butyl cellosolve. The use of the claimed makes it possible to make memebranes having maximum pore diameter of not greater than 2,5•10m and breaking strength of at least 2.0 MPa, total porosity of membranes being at least 60%. EFFECT: improved properties of the composition.
Claims (1)
Предполагаемое изобретение относится к пористым пленкам на основе полиолефинов, получаемых из растворов и может быть использовано в химической технологии при получении сепараторов аккумуляторных батарей. Предложена композиция, содержащая сэвилен, ксилол, бутилцеллозольв. Использование предлагаемой композиции позволяет получить мембраны с максимальным диаметром пор, не превышающем 2,5• 10-6м и прочностью при разрыве не менее 2,0 МПа, при этом общая пористость у мембран не менее 60%.The alleged invention relates to porous films based on polyolefins obtained from solutions and can be used in chemical technology for the production of battery separators. A composition comprising sevilen, xylene, butyl cellosolve is proposed. Using the proposed composition allows to obtain membranes with a maximum pore diameter of not more than 2.5 • 10 -6 m and a tensile strength of at least 2.0 MPa, while the total porosity of the membranes is not less than 60%.
