High-temperature-resistant fireproof material as well as preparation method and application thereof
The invention belongs to the technical field of preparation of fireproof materials, and particularly relates to a high-temperature-resistant fireproof material and a preparation method and applicationthereof. The high-temperature-resistant fireproof material comprises a gel material and a framework material, the mass fraction of aluminum oxide in the gel material is 33-50%, and the framework material is of a hollow structure. By controlling the mass fraction of aluminum oxide in the gel material to be 33-50%, it can be guaranteed that the gel material is subjected to a hydration reaction sufficiently, early strength is provided for the fireproof material, and the breakdown resistance of the fireproof material is improved; when the mass fraction of aluminum oxide in the gel material is lower than 33%, the high temperature resistance of the fireproof material is poor. In addition, silicate and aluminum oxide can generate high-temperature-resistant aluminum silicate at high temperature,and the aluminum silicate is good in high-temperature resistance, so that the high-temperature resistance of the fireproof material is improved. The thermal conductivity of the material can be greatlyreduced by controlling the framework material to be a material with a hollow structure.
本发明属于防火材料制备技术领域，具体涉及一种耐高温防火材料及其制备方法和应用。该耐高温防火材料包括凝胶材料和骨架材料，凝胶材料中氧化铝的质量分数为33‑50％，所述骨架材料为具有空心结构的材料。通过控制凝胶材料中氧化铝的质量分数为33‑50％，可以保证凝胶材料充分发生水化反应，为防火材料提供早期强度，提高了防火材料的耐击穿性；当凝胶材料中氧化铝的质量分数低于33％时，防火材料的耐高温性较差。此外在高温下硅酸盐和氧化铝可以生成耐高温的硅酸铝，硅酸铝耐高温性好，从而提高防火材料的耐高温性。通过控制骨架材料为空心结构的材料，可以大幅度降低该材料的热导率。
