Fire-resistant gypsum board for building and preparation method of fire-resistant gypsum board
The invention discloses a building fire-resistant gypsum board, and the gypsum board is prepared from the following raw materials in parts by weight: 20 to 40 parts of glass fibers, 30 to 45 parts of diatomite, 20 to 35 parts of aluminum silicate, 50 to 65 parts of desulfurized gypsum, 15 to 25 parts of a foaming agent, 20 to 35 parts of ferric oxide, 20 to 35 parts of vinyl chloride resin, 10 to 15 parts of a pore forming agent and 10 to 15 parts of a toughening agent. The fire resistance of the gypsum board is improved, and the defect that the strength becomes low after moisture absorption due to high solubility in water and low softening coefficient of gypsum is overcome.
本发明公开了一种建筑用耐火石膏板，以重量份计，其原料包括：玻璃纤维20‑40份、硅藻土30‑45份、硅酸铝20‑35份、脱硫石膏50‑65份、发泡剂15‑25份、氧化铁20‑35份、氯乙烯树脂20‑35份、造孔剂10‑15份和增韧剂10‑15份。本发明增加了石膏板的耐火性，改善了石膏因在水中溶解度大，软化系数低，吸潮后强度变低的缺陷。
