Fireproof plate for cable trench and preparation method thereof
The invention discloses a fireproof plate for a cable trench and a preparation method of the fireproof plate. The raw materials of the fireproof plate comprise a gel material and a framework material, wherein a molar ratio of CaO to SiO2 in the gel material is 0.8-1.2; and the framework material is an inorganic material with a hollow structure, and the content of the framework material is 40-60 wt% based on the total mass of the gel material and the framework material. The preparation method comprises the following steps: uniformly mixing all the raw materials, adding water to obtain slurry, and filling a mold with the slurry; and putting the mold into a still kettle for steaming and pressing to obtain the high-temperature-resistant fireproof plate. According to the invention, the calcium-silicon ratio in the gel material is controlled, so the gel material can be fully hydrated to generate fibrous xonotlite, and thus, the toughness of the fireproof plate is improved; the breaking strength of the material is further improved through fibers; and the heat conductivity of the plate can be greatly reduced by controlling the framework material to be of the hollow structure.
本发明公开了一种电缆沟用防火板及其制备方法，其原料包括凝胶材料和骨架材料，所述凝胶材料CaO/SiO2摩尔比为0.8～1.2；所述骨架材料为具有空心结构的无机材料，以凝胶材料和骨架材料总质量计，所述骨架材料的含量为40‑60wt％。将所有原料混合均匀后，加水得到浆体，装模；模具放入蒸压釜中蒸压到耐高温防火板。本发明通过控制凝胶材料中的钙硅比，可以保证凝胶材料充分发生水化反应，生成纤维状的硬硅钙石，提高了防火板的韧性；通过纤维进一步提高材料的抗折强度；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。
