An additive potassium titanate whisker aramid paper and its preparation method

The present invention discloses a method for preparing aramid paper and adding potassium titanate whisker, by the addition of high performance, less expensive potassium titanate whisker, potassium titanate whisker and an aramid fiber dispersion are mixed and ease a homogeneous suspension copied on inclined wire machines the forming, pressing, drying and further pressing to obtain the aramid paper in a hot press. It can significantly reduce production costs aramid paper, aramid paper while improving the mechanical properties of aramid paper, especially high-temperature properties and wear resistance; in addition, aramid fibers and potassium titanate whiskers mixed, yielding "fiber - whiskers "coated fine structure, exert a synergistic fiber confounding effects, to improve the overall performance of the paper, to improve machine speed and productivity. The method of the present invention provides aramid paper compared to current conventional production, simple process, low production cost and excellent performance.
