Foam ceramic insulation material and preparation method thereof
The invention discloses a foam ceramic insulation material and a preparation method thereof. The preparation method comprises the steps of injecting a filling medium for a foam ceramic insulation material into a foam ceramic filter by virtue of vacuum equipment until gaps inside the filter are filled with the filling medium, and drying in a drying oven at 90-110 DEG C, wherein the foam ceramic filter has a mesh number of 300-400mesh/inch, a filter accuracy of 50-80ppi and a thickness of 40-60mm; the filling medium for the foam ceramic insulation material is prepared from the following raw materials in percentage by weight: 2-3 percent of sodium carboxymethyl cellulose, 38.8-56.0 percent of glass microspheres and the balance of water. The foam ceramic insulation material has excellent insulation performance, excellent compression strength, relatively high size accuracy, good flame retardance, good thermal shock resistance, low hot-shrinkage rate, low heat expansion coefficient, low production cost, simple preparation process and no special equipment, and is suitable for industrial production.
