Wind-pressure-resistant double-leaf fireproof door special for tunnel
The invention discloses a special wind-pressure-resistant double-leaf fireproof door for tunnels, which comprises a door frame and two door leaves, the door leaves are mounted in the door frame through hinges, each door leaf is composed of a plurality of layers of wind-pressure-resistant structures and filled with expanded vermiculite composite fireproof door core materials; the composite fireproof door core material is prepared from, by mass, 40%-50% of expanded vermiculite, 2%-5% of carbon fibers, 10%-20% of water glass, 2%-5% of rapid hardening sulphoaluminate cement, 5%-10% of nanometer titania, 2%-5% of polyvinyl alcohol, 5%-10% of superfine talcum powder, 5%-8% of cellulose, 10%-20% of quartz sand, 2%-5% of silicone acrylic resin and 2%-5% of K2SiF6. According to the wind-pressure-resistant fireproof door, nano titanium dioxide is adsorbed in the expanded vermiculite cavity, when the door is on fire, the nano titanium dioxide can play a role in ablation resistance, the strength of the expansion layer is improved, a burning-resistant high-temperature ceramic layer is finally formed to improve the fire endurance, and the fireproof effect of a tunnel can be effectively improved.
本发明公开了一种隧道专用的抗风压双扇防火门，包括门框及两个门扇，所述门扇通过合页安装于所述门框内，所述门扇由多层抗风压结构组成，并填充有膨胀蛭石类复合防火门芯材料；所述复合防火门芯材料由以下质量配比成分：膨胀蛭石40‑50％、碳纤维2‑5％、水玻璃10‑20％、快硬硫铝酸盐水泥2‑5％、纳米二氧化钛5‑10％、聚乙烯醇2‑5％、超细滑石粉5‑10％、纤维素5‑8％、石英砂10‑20％、硅丙树脂2‑5％、K2SiF6 2‑5％。本发明的抗风压防火门在膨胀蛭石空腔中吸附纳米二氧化钛，受火时，纳米二氧化钛可发挥耐烧蚀作用，提高膨胀层的强度，最终形成耐烧的高温陶瓷层以提高耐火极限，可以有效提升隧道的防火效果。
