Cable trench fireproof partition plate and preparation method thereof
The invention relates to a fireproof partition plate for a cable trench. The fireproof partition plate comprises ettringite used as an ablative material and hollow microspheres used for absorbing high-temperature expansion and decomposition water of the ablative material. The invention further provides a preparation method of the cable trench fireproof partition plate, powdery ettringite and/or ettringite in a binder hydrate are/is used as ablative components, hollow microspheres are used as a buffer adsorption material, reinforced fibers are added to improve the structural strength, and the cable trench fireproof partition plate is prepared. And bonding and molding the ablative component, the hollow microspheres and the reinforced fibers by using a binding agent to obtain the cable trench fireproof partition plate. Internal expansion caused by high-temperature water vapor released by the ablative material and shrinkage after dehydration of the ablative material are absorbed through the hollow microspheres, structural damage to the fireproof partition plate is avoided, and the fireproof performance and the structural strength at the high temperature are greatly improved.
一种电缆沟防火隔板，其包括：用作烧蚀材料的钙钒石和用于吸收所述烧蚀材料的高温膨胀和分解水的空心微球。本发明还提供一种电缆沟防火隔板的制备方法，以粉状的钙钒石和/或以结合剂水化物中钙钒石作为烧蚀组分，以空心微球作为缓冲吸附材料，加入增强纤维提高结构强度，利用结合剂将所述烧蚀组分、空心微球和增强纤维粘接成型得到电缆沟防火隔板。本发明通过空心微球来吸收烧蚀材料释放的高温水汽导致的内部膨胀以及烧蚀材料脱水后的收缩，避免对防火隔板产生结构性破坏，大幅提高防火性能及高温下的结构强度。
