摘要： 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.
摘要翻译： 本发明提供一种无机纤维纸，其基本上由无机材料组成，其单位面积重量小于100g / m 2，主要通过湿法制片方法制备。 无机纤维纸包括无机纤维和无机粘合剂作为材料，其中无机纤维已经用无机粘合剂彼此结合。 在无机纤维纸中，湿法制片时的杂质含量低，耐水性和柔软性好，能够实现令人满意的强度和高孔隙率。 无机纤维纸由平均纤维直径不大于5μm的无机纤维为60〜97质量％，主要由二氧化硅系片状无机材料构成的无机粘结剂为3〜40质量％ 通过BET法测定的比表面积的羟基含量为20μmol/ m 2以上的材料，通过激光散射测定的平均粒径为2μm以下 方法和纵横比不小于10。
