Composite fire-resistant felt for bridge steel cable as well as preparation method and application of composite fire-resistant felt
The invention discloses a preparation method of a composite fire-resistant felt for a bridge steel cable. The preparation method comprises the following steps: (1) preparing sol; (2) dipping a basalt fiber felt into the sol, aging in a drying oven at 50 DEG C for 4 hours, and drying in a high-pressure kettle to obtain a basalt fiber aerogel felt; (3) putting the basalt fiber aerogel felt on the outer layer, and combining the basalt fiber aerogel felt with the inner-layer basalt fiber felt through a sewing process to prepare a composite fiber felt; and (4) spraying a layer of flexible epoxy resin film on the surface of the composite fiber felt to prepare the fire-resistant double-layer structure composite felt. The invention further discloses application of the double-layer composite fire-resistant felt in a bridge steel cable, and the application is characterized in that the bridge steel cable is coated with the double-layer composite fire-resistant felt to be compacted, and the surface of the double-layer composite fire-resistant felt is coated with weather-resistant sealant. The invention relates to the technical field of fire-resistant materials, in particular to a composite fire-resistant felt for a bridge steel cable and a preparation method and application of the composite fire-resistant felt.
本发明公开了一种桥梁钢索用复合抗火毡的制备方法，包括以下步骤：(1)制备制得溶胶；(2)将玄武岩纤维毡浸渍到所述溶胶中，在50℃的烘箱中老化4小时，再在高压釜中进行干燥后得到玄武岩纤维气凝胶毡；(3)将玄武岩纤维气凝胶毡置于外层，与内层玄武岩纤维毡通过缝纫工艺相结合制成复合纤维毡；(4)在复合纤维毡表面喷涂一层柔性环氧树脂膜制成抗火用双层结构复合毡。本发明还公开了上述双层复合抗火毡在桥梁钢索中的应用，其特征在于，将双层复合抗火毡包覆到桥梁钢索上压实，并在双层复合抗火毡表面涂刷耐候密封胶。本发明涉及抗火材料技术领域，具体是指一种桥梁钢索用复合抗火毡及其制备方法和应用。
