High-density ceramic fiberboard and preparation method thereof
The invention provides a preparation method of a high-density ceramic fiberboard, which comprises the following steps: A) mixing water, an inorganic binding agent, a dispersing agent, a surfactant andan infrared opacifying agent to obtain a suspension, pulping the ceramic fibers, and mixing the pulped ceramic fibers with a refractory filler and a filter aid to obtain slurry; b) mixing the suspension with the slurry to obtain slurry; and C) molding and pressing the slurry to obtain the high-density ceramic fiberboard. The invention further provides the high-density ceramic fiber board. The density of the high-density ceramic fiberboard added with the infrared opacifying agent is 600-1000 kg/m3, and the high-density ceramic fiberboard can be used in the field of heat preservation and insulation, is particularly suitable for heat preservation and insulation of a fire facing surface at a high temperature, has the advantages of high strength, compressive strength of 12 MPa and low heat conductivity coefficient, and has an average heat conductivity coefficient of less than 0.125 W/(m.k)@700 DEG C.
本发明提供了一种高密度陶瓷纤维板的制备方法，包括以下步骤：A)将水、无机结合剂、分散剂、表面活性剂和红外遮光剂混合，得到悬浮液；将陶瓷纤维打浆后与耐火填料、助滤剂混合，得到料浆；B)将所述悬浮液与所述料浆混合，得到浆料；C)将所述浆料进行成型、压制，得到高密度陶瓷纤维板。本申请还提供了一种高密度陶瓷纤维板。本申请制备的添加有红外遮光剂的高密度陶瓷纤维板，密度为600～1000kg/m3，可以用于保温隔热领域，尤其适用于高温下迎火面的保温隔热，其具有强度高，耐压强度为12MPa，导热系数低的优点，平均700℃导热系数为＜0.125W/(m·k)。
