Low-porosity high-thermal-shock-resistance clay brick and preparation method thereof
The invention discloses a clay brick with low porosity and high thermal shock resistance. The clay brick is prepared from the following raw materials in parts by weight: 5-15 parts of mullite particles with Al2O3 content of greater than or equal to 70% and less than or equal to 90% and Fe2O3 content of less than or equal to 2%, 40-90 parts of flint clay with Al2O3 content of greater than or equalto 45% and less than or equal to 80% and Fe2O3 content of less than or equal to 1%, 1-10 parts of light calcined magnesia powder, and 5-15 parts of white mud with Al2O3 content of greater than or equal to 34% and less than or equal to 60% and Fe2O3 content of less than or equal to 2%. According to the invention, the apparent porosity of a traditional clay brick can be effectively reduced, and thethermal shock resistance is improved.
本发明公开了一种低气孔高抗热震粘土砖，由以下重量份数的原料制成，由70％≤Al2O3≤90％且Fe2O3≤2％的莫来石颗粒5‑15份，45％≤Al2O3≤80％且Fe2O3≤1％的焦宝石40‑90份，轻烧镁砂粉1‑10份，34％≤Al2O3≤60且Fe2O3≤2％的白泥5‑15份。本发明可有效降低传统粘土砖的显气孔率且提高抗热震性能。
