The invention discloses an explosion venting and sound insulation fireproof plate and a preparation method thereof, and belongs to the technical field of materials. The explosion venting sound insulation fireproof plate contains the expanded vermiculite coated and modified by the hardened cement with a high doping amount, compared with common vermiculite, the expanded vermiculite is not prone to deformation and rebound after being pressed, and meanwhile the porous structure of the expanded vermiculite is reserved; therefore, the reaction mechanism is basically similar to that of the existing high-temperature hydrated calcium silicate combined expanded vermiculite fireproof plate when the product is prepared, but the product has lower surface density, and meanwhile, the strength, the fireproof performance and the sound insulation performance of the product are relatively excellent. 本发明公开了一种泄爆隔声防火板及其制备方法，属于材料技术领域。本发明所述泄爆隔声防火板中含有高掺杂量的硬化水泥包覆改性的膨胀蛭石，相比于普通蛭石该组分在受压后不易出现变形与回弹，同时也保留了膨胀蛭石的多孔结构，因此在产品制备时反应机理基本与现有高温水化硅酸钙结
