High temperature resistant calcium silicate thermal insulation material and preparation method thereof
The invention discloses a high temperature resistant calcium silicate thermal insulation material and a preparation method thereof. The calcium silicate thermal insulation material is mainly composed of 5CaO.6SiO2.5H2O and 6CaO.6SiO2.5H2O, wherein 5CaO.6SiO2.5H2O accounts for 30 to 45 wt% of the total weight of the calcium silicate thermal insulation material, the highest application temperature of 5CaO.6SiO2.5H2O is 650 DEG C; 6CaO.6SiO2.5H2O accounts for 55 to 70 wt% of the total weight of the calcium silicate thermal insulation material, and the highest application temperature of 6CaO.6SiO2.5H2O is 1000 DEG C. Two substances are evenly mixed to form a calcium silicate thermal insulation material, which is suitable for being used at a temperature of 650 to 800 DEG C. The dynamic method and static method are combined to produce the calcium silicate thermal insulation material, which fulfills the gap that no calcium silicate thermal insulation material can be used in the temperature range of 650 to 800 DEG C, and the provided material is unique and has a good thermal insulation effect. Moreover, the fineness of raw materials is optimized during the preparation process, the reaction rate is accelerated, and the product yield is improved.
