Abstract

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.

Description

technical field [0001] The invention relates to a foam ceramic thermal insulation material and a preparation method thereof, belonging to the field of thermal insulation materials. Background technique [0002] With the depletion of the traditional three major fossil energy sources, energy conservation and environmental protection have become an increasingly hot topic. At present, my country's building energy consumption has risen sharply year by year, reaching 45% of the country's total energy consumption, which has caused a huge burden on the development of the national economy. Therefore, building energy saving is imminent. Maintaining the temperature inside the building and reducing its heat loss is an effective way to improve the energy efficiency of the building. At present, the insulation materials used in more than 80% of domestic buildings are mainly organic materials such as expanded polystyrene board (EPS), extruded polystyrene board (XPS), sprayed polyurethane ...
