METHOD FOR PRODUCING ARAMID PAPER

A method for producing aramid paper that involves performing a hot-pressing step of mixing short aramid fibers and aramid fibrids in a mass ratio of 60/40 to 10/90 and forming a sheet, sandwiching the sheet obtained between a pair of heating elements, and applying a pressure of at least 500 kg/cm2 a...

Zusammenfassung:	A method for producing aramid paper that involves performing a hot-pressing step of mixing short aramid fibers and aramid fibrids in a mass ratio of 60/40 to 10/90 and forming a sheet, sandwiching the sheet obtained between a pair of heating elements, and applying a pressure of at least 500 kg/cm2 at least two times, wherein the hot-pressing step that is performed at least two times comprises a hot-pressing step (a) at a temperature exceeding the glass transition temperature of aramid and a hot-pressing step (b) performed thereafter at a temperature less than the glass transition temperature of aramid. 芳族聚酰胺纸的制造方法，所述芳族聚酰胺纸的制造方法包括：将芳族聚酰胺短纤维和芳族聚酰胺纤条体以60/40～10/90的质量比混合形成片状物，将所得片状物夹在一对发热体之间，进行至少2次施加500kg/cm2以上的压力的热压加工处理工序，其中，进行至少2次的热压加工处理工序包括：在超过芳族聚酰胺的玻璃化转变温度的温度下的热压加工处理工序(a)；以及之后进行的在低于芳族聚酰胺的玻璃化转变温度的温度下的热压加工处理工序(b)。
