Aerogel composite ceramic fiber board as well as preparation method and application thereof

The invention provides application of aerogel and a binding agent in preparation of a ceramic fiber board. The binding agent is a water-based acrylic emulsion and/or a water-based polyurethane emulsion. The invention further provides an aerogel composite ceramic fiber board and a preparation method thereof. The aerogel composite ceramic fiber board provided by the invention is low in heat conductivity coefficient, excellent in thermal insulation performance and mechanical property, low in heat conductivity coefficient and good in flexibility, does not drop powder during processing, can be applied in manners of flat laying, small-amplitude bending and the like, further greatly improves the compression strength after burning, and can meet the thermal insulation requirements under different working conditions. Meanwhile, the preparation process is simple, mild in condition, easy to control, low in production cost and environmentally friendly, and popularization and application of industrial continuous production
