Lightweight high-strength thermal-insulation refractory brick and preparation method thereof
The invention belongs to the technical field of refractory materials, and discloses a lightweight high-strength thermal-insulation refractory brick and a preparation method thereof. The lightweight high-strength thermal-insulation refractory brick is prepared from the following raw materials in parts by mass: 65-80 parts of aluminum ash, 0.1-0.5 part of an exciting agent, 5-10 parts of a tackifier, 5-7 parts of a rheology improver, 3-7 parts of a medium-temperature foaming agent, 0.1-0.5 part of a high-temperature foaming agent, 5-10 parts of a setting agent, 0.1-0.5 part of a water reducing agent and 15-20 parts of water. According to the invention, the aluminum ash is used as a main raw material, and a process of high-temperature foaming and sintering after low-temperature excitation self-foaming shaping is adopted, so that the aluminum ash in the electrolytic aluminum industry can be effectively consumed, the problem of hazardous waste disposal is solved, efficient utilization of resources is realized, and the problem of fluorine pollution of the aluminum ash is also solved; and the prepared refractory brick has relatively high compressive strength, relatively low volume density, relatively high refractoriness and relatively high added value of products.
本发明属于耐火材料技术领域，公开了一种轻质高强保温耐火砖及其制备方法。该轻质高强保温耐火砖由包含以下质量份数的原料制备而成：铝灰65～80份，激发剂0.1～0.5份，增粘剂5～10份，流变改善剂5～7份，中温发泡剂3～7份，高温发泡剂0.1～0.5份，定型剂5～10份，减水剂0.1～0.5份，水15～20份。本发明以铝灰为主要原料，采用低温激发自发泡定型后，再高温发泡、烧结的工艺，可有效消耗电解铝行业的铝灰，解决了危废处置的问题，实现了资源的高效利用，还解决了铝灰的氟污染问题，且制备的耐火砖具有较高的耐压强度、较低的体积密度和较高的耐火度，产品附加值较高。
