Inorganic fireproof coating for tunnels and preparation method thereof
The invention relates to an inorganic fireproof coating for tunnels, wherein the coating is characterized in that the coating is powder; every 100 parts by weight of the powder material comprises the following components: 32 to 36 parts by weight of Portland cement, 5.5 to 7.5 parts by weight of high-alumina cement, 6.5 to 8.8 parts by weight of water-soluble potassium silicate, 12 to 25 parts by weight of expanded perlite, 7.4 to 17.4 parts by weight of kaolin, 3.7 to 6.2 parts by weight of aluminum silicate fiber, 2.5 to 3.7 parts by weight of mica powder, 5 to 15 parts by weight of fly ash hollow floating beads, 5 to 8 parts by weight of wollastonite powder and 10 to 15 parts by weight of expanded vermiculite. The inorganic fireproof material for the tunnels has the advantages of small coating layer thickness, light coating layer mass, low dry density, material saving, low heat conduction, capability of greatly prolonging the fire-resistant time of a steel structure, beautiful coating layer, no hollowing, no cracking, acid resistance, low hygroscopicity, mildew resistance, environmental protection and no toxicity in case of fire, convenience in construction, low construction cost and cost and the like; and the problems of rapid strength loss, burning collapse and the like of a concrete building structure caused by fire catching in a relatively closed tunnel environment are solved.
本发明涉及一种隧道无机防火涂料，其特征在于，该涂料为粉料，且每100重量份粉料含有如下组分：32‑36重量份的硅酸盐水泥、5.5‑7.5重量份的高铝水泥、6.5‑8.8重量份的水溶性硅酸钾、12‑25重量份的膨胀珍珠岩、7.4‑17.4重量份的高岭土、3.7‑6.2重量份的硅酸铝纤维、2.5‑3.7重量份的云母粉、5‑15重量份的粉煤灰空心漂珠、5‑8重量份的硅灰石粉、10‑15重量份的膨胀蛭石。本发明的隧道无机耐火材料，具有涂层厚度小、涂层质量轻、干密度低，省料，热传导低，可大幅提高钢结构的耐火时间、涂层美观、不空鼓、不开裂、耐酸性、吸湿性小，防霉性、遇火环保无毒性、施工方便、施工造价与成本低等优点，以解决隧道相比密闭的环境下因着火引起混凝土垒砌结构的强度快速损失和烧塌等问题。
