Composite board for evacuation platform of subway tunnel
The invention discloses a composite board for an evacuation platform of a subway tunnel, belonging to the technical field of composite materials for subway tunnel construction. The composite board comprises the following raw materials in percentage by mass: 60%-85% of glass fiber twistless roving and/or stitch-bonded felt, 7.5%-20% of phenolic resin, 0.45%-1.2% of a curing agent, 0.375%-1% of a coupling agent, 1.5%-4% of aluminum hydroxide, 1.8%-4.8% of magnesium hydroxide, 0.525%-1.4% of a release agent, 1.5%-4% of industrial methanol, 0.6%-1.6% of iron oxide and 0.75%-2% of water. The composite board for the evacuation platform of the subway tunnel is high in compressive strength; compared with traditional cement-based and concrete evacuation platforms, the composite board for the evacuation platform of the subway tunnel has the advantages that under the condition of the same size and the same thickness, the dead weight of the evacuation platform is about 1/5 the dead weight of the cement-based evacuation platform and 1/8 the dead weight of the concrete evacuation platform, and the compressive strength of the evacuation platform is twice the compressive strength of the cement-based evacuation platform and 5 times the compressive strengt of the concrete evacuation platform.
一种地铁隧道疏散平台用的复合板材，属于地铁隧道建设用复合材料的技术领域，按质量百分比计，包括以下原料：玻璃纤维无捻粗纱和/或缝编毡60％～85％、酚醛树脂7.5％～20％，固化剂0.45％～1.2％，偶联剂0.375％～1％，氢氧化铝1.5％～4％，氢氧化镁1.8％～4.8％，脱模剂0.525％～1.4％，工业甲醇1.5％～4％，氧化铁0.6％～1.6％，水0.75％～2％。本发明地铁隧道疏散平台用的复合板材抗压强度高，对比传统水泥基、混凝土疏散平台，本发明地铁隧道疏散平台用的复合板材能够做到在同尺寸厚度条件下，自重约为水泥基的1/5、混凝土的1/8，抗压强度却为水泥基的2倍、混凝土的5倍。
