Low-density fireproof plate and preparation method thereof
The invention discloses a low-density fireproof plate and a preparation method thereof, and relates to the technical field of fireproof building materials.The low-density fireproof plate is prepared from, by weight, 40-50 parts of light materials, 15-20 parts of cement, 8-10 parts of wood pulp, 10-15 parts of quartz sand, 5-7 parts of aluminum oxide, 5-10 parts of mica sheets, 3-5 parts of vermiculite powder, 1-5 parts of wollastonite and 0.5-1 part of waterproof agent; the preparation method of the light material comprises the following steps: uniformly stirring calcium oxide, diatomite, sodium hydroxide and water, raising the pressure and the temperature to 0.8-1.2 MPa and 170-185 DEG C, carrying out heat preservation reaction for 4-7 hours, and cooling and depressurizing to prepare the light material. The low-density fireproof plate provided by the invention has the characteristics of low density and high strength, and is good in fireproof, high-temperature-resistant, heat-insulating and sound-absorbing effects, stable in size and easy to process.
本发明公开了一种低密度防火板及其制备方法，涉及防火建筑材料技术领域，原料按重量份数包括轻料40‑50份、水泥15‑20份、木浆8‑10份、石英砂10‑15份、氧化铝5‑7份、云母片5‑10份、蛭石粉3‑5份、硅灰石1‑5份和防水剂0.5‑1份；其中，轻料的制备方法，是先将氧化钙、硅藻土、氢氧化钠和水搅拌均匀后，先升压、升温至(0.8‑1.2)MPa和(170‑185)℃，保温反应4‑7h，降温降压后制备而成。本发明提供的低密度防火板，兼具低密度、高强度的特性，防火、耐高温、隔热、吸音效果好，尺寸稳定，易加工。
