High-refractoriness-under-load mullite composite brick and preparation method thereof
The invention relates to the technical field of refractory materials, and discloses a high-refractoriness-under-load mullite composite brick which comprises the following raw materials in parts by weight: 30-50 parts of corundum mullite, 120-150 parts of bauxite clinker, 3-7 parts of silica powder, 2-6 parts of nanoscale metal aluminum powder, 10-15 parts of sillimanite, 3-5 parts of phosphoric acid and additional paper pulp waste liquid accounting for 2-4% of the total weight of the various raw materials. According to the high-refractoriness-under-load mullite composite brick and the preparation method thereof, after a green brick is placed in a mold, a plate is driven by a lifting device to move up and down, so that the green brick is extruded, air holes in the prepared composite brick can be greatly reduced, and the strength and the comprehensiveness of the composite brick are improved; phosphoric acid, silica powder, nano-scale metal aluminum powder and fragments are mixed, phosphoric acid reacts with a silicon-aluminum system and corundum mullite to generate compound phosphate with cementing capacity, and the raw materials can be mutually combined, so that the internal bonding performance is improved.
本发明涉及耐火材料技术领域，且公开了一种高荷软莫来石复合砖，包括以下重量份数配比的原料：刚玉莫来石30‑50份，铝矾土熟料120‑150份，硅微粉3‑7份，纳米级金属铝粉2‑6份，硅线石10‑15份，磷酸3‑5份，外加占上述各种原料总重量2％到4％的纸浆废液。该高荷软莫来石复合砖及其制备方法，在将砖坯放置到模具内后，通过升降装置带动一块板进行上下移动，从而对砖坯进行挤压，这种方式能够极大的减少制成后的复合砖内部气孔，使复合砖自身的强度以及其综合性得到提高，通过磷酸、硅微粉、纳米级金属铝粉和碎块进行混合，磷酸与硅铝系和刚玉莫来石发生反应生成具有胶结能力的复式磷酸盐，可将原料相互结合起来，使其内部粘接性能得到提高。
