Abstract

The invention belongs to the technical field of ceramic fiber materials and in particular relates to a high-temperature resistant ceramic fiber plate. The high-temperature resistant ceramic fiber plate is prepared from the following raw materials in parts by weight: 95-96 parts of alumina silicate fiber, 1-2 parts of dispersing agent and 3-4 parts of zirconium latex, wherein the dispersing agent is a mixture of Na2SiO3 and CaCO3 and the zirconium latex is a mixture of ZrO2, Y2O3 and H2O2. The invention also provides a preparation method of the high-temperature resistant ceramic fiber plate. The preparation method comprises the following steps: mixing and stirring the raw materials, carrying out wet vacuum molding, drying and processing to obtain a product, wherein the drying time is 110-120 DEG C and the time is 22-24 hours. The high-temperature resistant ceramic fiber plate prepared by the preparation method can bear the high temperature being above 1100 DEG C and does not lose cohesive force.

Description

technical field [0001] The invention belongs to the technical field of ceramic fiber materials, and in particular relates to a high-temperature-resistant ceramic fiber board. Background technique [0002] In addition to the excellent performance of the corresponding loose ceramic fiber cotton, the ceramic fiberboard has a hard texture, excellent toughness and strength, and has excellent wind erosion resistance. It does not expand when heated, is light in weight, convenient in construction, and can be cut and bent at will. It is an ideal energy-saving material for kilns, pipelines and other insulation equipment. [0003] When the ceramic fiberboard prepared in the prior art encounters high temperature (above 800° C.), it loses its binding force and presents a loose state. Contents of the invention [0004] The object of the present invention is to provide a high-temperature-resistant ceramic fiber board, which can withstand high temperatures above 1100°C without losing coh...
