Fireproof structure of bridge cable
The invention discloses a fireproof structure of a bridge cable, which comprises a flexible fireproof thermal insulation material layer, a fireproof winding coating cloth layer, a mass transfer barrier layer and an expansion type fireproof sealant layer which are sequentially compounded from inside to outside, the fire-resistant winding coating cloth layer and the mass transfer blocking layer can form a dense layer composed of inorganic filler and a silicon dioxide framework at high temperature, so that further mass transmission of hot air to the flexible fire-resistant thermal insulation material layer is blocked; the fireproof structure composed of the flexible fireproof heat insulation material layer, the fireproof winding wrapping cloth layer, the mass transfer blocking layer and the expansion type fireproof sealant layer is excellent in fireproof heat insulation effect, the epoxy ester, the expansion fireproof sealant and the whole fireproof structure are simple in design, the preparation method is convenient and fast, and good economic and social benefits are achieved.
本发明公开了一种桥梁缆索的防火结构，包括，由内到外依次复合形成的柔性耐火隔热材料层、耐火缠绕包覆布层、传质阻隔层以及膨胀型防火密封胶层；本发明设计的耐火缠绕包覆布层和传质阻隔层在高温下会形成由无机填料和二氧化硅骨架组合的密实层，阻隔热风进一步向柔性耐火隔热材料层的质量传输，这样由柔性耐火隔热材料层、耐火缠绕包覆布层、传质阻隔层以及膨胀型防火密封胶层组成的防火结构，防火隔热效果优异，环氧酯、膨胀防火密封胶以及整个防火结构设计简洁、制备方法便捷，具有良好的经济与社会效益。
