Alkaline electrolyzed water device sealing element and preparation method thereof
The invention provides a sealing element of an alkaline water electrolysis device and a preparation method of the sealing element. The method comprises the following steps: S1, adding polytetrafluoroethylene into a solvent, and carrying out first stirring to obtain a first membrane solution; s2, adding an initiator into the first membrane liquid, and performing second stirring to obtain second membrane liquid; s3, adding perfluoropropyl vinyl ether into the second membrane liquid, and performing third stirring to obtain third membrane liquid; s4, adding an inorganic filler into the third membrane solution, and performing fourth stirring to obtain a fourth membrane solution; and S5, the fourth membrane liquid is subjected to tape casting treatment and sintering treatment in sequence, and the alkaline electrolyzed water device sealing element is obtained. According to the invention, polytetrafluoroethylene is used as a base material, perfluoropropyl vinyl ether is introduced to modify the base material, and an inorganic filler is used as an auxiliary material, so that the alkaline water electrolysis device sealing element which has good sealing performance, mechanical strength and creep resistance and also shows excellent strong alkali aging resistance is prepared.
本发明提供了一种碱性电解水装置密封件及其制备方法。该方法包括：步骤S1，将聚四氟乙烯加入溶剂中，经第一搅拌得到第一膜液；步骤S2，将引发剂加入第一膜液中，经第二搅拌得到第二膜液；步骤S3，将全氟丙基乙烯基醚加入第二膜液中，经第三搅拌得到第三膜液；步骤S4，将无机填料加入第三膜液中，经第四搅拌得到第四膜液；步骤S5，第四膜液依次经流延处理和烧结处理，得到碱性电解水装置密封件。本发明将聚四氟乙烯作为基材，通过引入全氟丙基乙烯基醚对其改性，同时辅助无机填料，制备得到具有良好的密封性、力学强度以及抗蠕变性，同时表现出优良的抗强碱老化能力的碱性电解水装置密封件。
