A novel fire-proofing coiled material used for wrapping around the steel or other members to play its water-proofing, decorative and protecting roles is composed of high-toughness thin basic material and expansive fire-proofing composition contained in the cavities of said basic material. When fire accident takes place, its surface layer is fused and the fire-proofing composition is then expanded to increase its thickness by tens times, so forming a thick fire-proof layer. 本发明是用于保护钢结构或其他结构件的新型防火材料，它同时具备防火、装饰、防护三重功能，它由强韧的薄层基料和包容在基料空腔中的膨胀防火组合物组成，表面坚固、光滑、耐磨、防潮、轻便、美观、可洗刷，在无火灾时起保护和装饰作用，遇火灾时，表层的基料首先软化熔融或破裂，里面的防火组合物迅速向外膨胀，增厚数十倍，形成厚实的防火阻挡层，耐火极限可大于3小时，采用本发明保护钢结构或其他结构件，施工简便，一次成型，经济高效。
