The invention discloses a high-strength fly ash brick containing wood fibers. The high-strength fly ash brick is prepared from the following raw materials in parts by weight: 100-120 parts of fly ash,20-30 parts of modified fibers, 15-20 parts of a flame-retardant filler, 10-15 parts of gravels, 8-10 parts of quick lime and 10-20 parts of distilled water. According to the invention, the modifiedfibers and the flame-retardant filler are prepared, the surface of the modified fibers has a layer of a hydrophobic film, so the fly ash brick can be effectively prevented from absorbing water, the strength of the modified fibers is improved; compared with an existing organic phosphorus flame retardant, the volatility of the flame-retardant filler is greatly reduced, so the flame retardance of thefly ash brick is more durable; and magnesium hydroxide is added and subjected to ultrasonic treatment, and the magnesium hydroxide is embedded into grooves in the surface of a graphene carrier to prepare the flame-retardant filler, and thus, the flame-retardant filler can release a large amount of water to dilute oxygen on the surface of a combustible material during combustion, active magnesiumoxide generated by decomposition is attached to the surface of the combustible material, and combustion is further prevented.
本发明公开了一种含有木质纤维的高强度粉煤灰砖，由如下重量份原料制成：粉煤灰100‑120份、改性纤维20‑30份、阻燃填料15‑20份、碎石10‑15份、生石灰8‑10份、蒸馏水10‑20份；并制备了改性纤维和阻燃填料，该改性纤维表面含有一层憎水膜能够有效的防止粉煤灰砖吸水并提升自身强度，该阻燃填料与现有的机磷阻燃剂相比，挥发性大大降低，使得粉煤灰砖的阻燃性更持久，并加入氢氧化镁进行超声处理，使得氢氧化镁镶嵌在石墨烯载体表面凹槽中，制得阻燃填料，进而使得该阻燃填料在燃烧时能够放出大量水分稀释燃物表面的氧气,分解生成的活性氧化镁附着于可燃物表面，又进一步阻止了燃烧的进行。
