Compared with the traditional refractory insulating plate, the graphite silicon refractory insulating plate prepared by the invention has the following advantages:
1. high fire resistance: the melting point of the graphite silicon fireproof heat insulation board is more than 2000 ℃, and the strength and the structural integrity of the graphite silicon fireproof heat insulation board are not reduced in a test environment of 850-1100 ℃;
2. the heat insulation performance is good: the normal temperature heat conductivity coefficient (25 ℃) of the graphite silicon fireproof heat insulation plate is less than or equal to 0.042W/(m.K), and the high temperature heat conductivity coefficient (1000 ℃) is less than or equal to 0.091W/(m.K);
3. the volume and the mass are light: the graphite silicon fireproof insulation board is a light fireproof material, and the density of the graphite silicon fireproof insulation board is only 180-260 KG/m;
4. the structural strength is high: the graphite silicon fireproof heat insulation board is a hard board, and overcomes the defects of low strength, fiber shedding and the like of light fireproof materials such as rock wool, ceramic fiber cotton and the like;
5. the construction efficiency is high: compared with the existing construction scheme of wrapping rock wool and fireproof plates outside the metal air pipe, the fireproof heat insulation plate can be directly applied to construction after being molded, the fireproof plates do not need to be attached to the surfaces of the fireproof heat insulation plates, the construction efficiency is greatly improved, and timely delivery of projects is ensured;
