Title:

INORGANIC FIBER PAPER

Document Type and Number:

WIPO Patent Application WO/2006/057240

Kind Code:

A1

Abstract:

This invention provides an inorganic fiber paper that consists essentially of inorganic materials and has a basis weight of less than 100 g/m² and has been mainly produced by a wet sheet making method. The inorganic fiber paper comprises inorganic fibers and an inorganic binder as materials, wherein the inorganic fibers have been bound to each other with the inorganic binder. In the inorganic fiber paper, the content of impurities during wet sheet making is low, the water resistance and flexibility are good, and satisfactory strength and high porosity can be realized. The inorganic fiber paper is produced from a material comprising 60 to 97% by mass of inorganic fibers having an average fiber diameter of not more than 5 μm and 3 to 40% by mass of an inorganic binder composed mainly of a silica-based flaky inorganic material that has a hydroxyl group content per specific surface area of not less than 20 µmol/m² as measured by a BET method, an average particle diameter of not more than 2 µm as measured by a laser scattering method and an aspect ratio of not less than 10.
