The invention provides a building fire-resistant gypsum board and a preparation method thereof, and relates to the technical field of building materials. The invention relates to a fire-resistant gypsum board for a building. The material comprises the following raw materials: 20-40 parts of calcium sulfate dihydrate, 30-45 parts of diatomite, 20-35 parts of silicate, 50-65 parts of desulfurized gypsum, 15-25 parts of a foaming agent, 20-35 parts of aluminum oxide, 20-35 parts of polypropylene fiber, 20-35 parts of vinyl chloride resin, 10-15 parts of a pore forming agent, 10-15 parts of silicon carbide, 10-15 parts of paper pulp, 10-15 parts of ammonium bicarbonate, 10-15 parts of an acrylate reinforcing agent and 10-15 parts of a toughening agent. After the materials are mixed, the gypsum board with good performance can be formed, the gypsum board has high strength, fire resistance and sound insulation performance, the calcium sulfate dihydrate can absorb a large amount of heat to play a role in flame retardance, and the internal polypropylene fiber and paper pulp improve the fracture load and ensure the stability of the gypsum board.
本发明提供一种建筑用耐火石膏板及其制备方法，涉及建筑材料技术领域。该一种建筑用耐火石膏板，以重量份计，其原料包括：二水合硫酸钙20‑40份、硅藻土30‑45份、硅酸盐20‑35份、脱硫石膏50‑65份、发泡剂15‑25份、氧化铝20‑35份、聚丙烯纤维20—35份、氯乙烯树脂20‑35份、造孔剂10‑15份、碳化硅10—15份、纸浆10—15份、碳酸氢铵10—15份、丙烯酸酯增强剂10—15份和增韧剂10‑15份。通过这些材料经过混合后，可以形成一种具有良好性能的石膏板，具有较高的强度、耐火性和隔音性能，二水合硫酸钙够吸收大量的热量起到阻燃的作用，内部的聚丙烯纤维和纸浆提高了断裂荷载，保证石膏板的稳定性。
