Fireproof plate special for top of tunnel
The invention belongs to the technical field of fireproof materials, and particularly relates to a fireproof plate special for the top of a tunnel. According to the fireproof plate special for the topof the tunnel, the composite material is prepared from the following raw materials in parts by weight: 24.5 to 30.5 parts of magnesium oxide, 15 to 19 parts of magnesium sulfate, 24.2 to 30.2 parts of thermal insulation material, 0.16 to 0.24 part of non-woven fabric, 1.7 to 2.1 parts of glass fiber cloth, 0.45 to 0.55 part of glass fiber, 0.08 to 0.12 part of trace substance and 38 to 42 parts of water. The fireproof plate has very excellent fireproof and heat-insulating properties, temperature resistance of 1500 DEG C, the density of the plate is about 1.05 t/m < 3 >, the thickness of the fireproof plate is 30mm, the temperature of the fireproof plate is 1350 DEG C after the fireproof plate is fired, the plate does not crack, heat energy transmission is blocked, it is guaranteed that the temperature of the back face of the plate is within 380 DEG C within 2 h, the building main body structure on the back face of the plate is thoroughly protected, and the fireproof plate is a preferred fireproof lining material for the existing tunnel main body structure capable of meeting the RWS fireproof standard.
本申请属于防火材料技术领域，具体的，本发明涉及一种隧道顶部专用防火板。本发明提供了一种隧道顶专用防火板，按重量份计，其制备原料包括，氧化镁24.5‑30.5份，硫酸镁15‑19份，隔热材料24.2‑30.2份、无纺布0.16‑0.24份，玻纤纤维布1.7‑2.1份，玻璃纤维0.45‑0.55份、微量物质0.08‑0.12份、水38‑42份。所述防火板具有非常出色的防火保温性能，耐温1500度，板材密度在1.05t/m左右，加以所述防火板厚度为30mm，防火板受火后温度1350度，板材不会出现裂纹，且阻隔热能传递，保证2h内板材背面温度在380度内，彻底保护了板材背面的建筑主体结构，是目前隧道主体结构能达到RWS耐火标准下的首选的防火内衬材料。
