Foamed ceramic thermal insulation board and manufacturing process thereof
The invention relates to a foamed ceramic thermal insulation board, which is characterized in that it comprises the following raw materials by weight: 80-90 parts of silica, 30-40 parts of aluminum oxide, 4-5 parts of magnesium oxide, 5-8 parts of kaolin, 8-12 parts of water glass, and 25-30 parts of starch. The particle size of the starch is 3-5 micrometers, and the particle sizes of the rest raw materials are all 75-100 micrometers. The manufacturing process provided by the invention has the characteristics of low cost, environmental protection and no pollution. With starch as the foaming agent, under the conditions of the invention, uniform and compact closed-cell bubbles are produced, the thermal insulation performance is greatly improved, and with proper amounts of magnesium oxide and aluminum oxide, the strength is also improved obviously.
