The invention discloses a refractory foamed brick and a preparation method thereof, and relates to the technical field of building ceramics. The raw materials of the refractory foamed bricks include 70-98 parts of silicate main material, 0.3-1 part of foaming agent, 2-8 parts of titanate and 0.1-0.5 part of diluent. By introducing titanate into the raw material formula, the fire resistance limit performance of refractory foamed bricks is significantly improved, and cracking will not occur after long-term high-temperature heating. The preparation method of refractory foamed bricks, through the improvement of formula raw materials, especially the addition of titanate, significantly improves the fire resistance limit performance of refractory foamed bricks, and solves a major problem that restricts the application of foamed bricks for a long time. It has broad application prospects in the field of building materials. |
