Gypsum-based fireproof door core plate and preparation method thereof
The invention provides a gypsum-based fireproof door core plate. The plate is characterized by comprising the following raw materials in parts by weight: 400-500 parts of phosphogypsum-based alpha high-strength gypsum, 0.1-1.5 parts of fibers, 5-8 parts of a foaming agent, 1-2 parts of a surfactant, 5-10 parts of an emulsion, 0.5-1 part of PVA and 180-250 parts of water. The dry density of the prepared fireproof door core plate is 280-400 kg/m<3>, wherein alpha-type high-strength gypsum uses the industrial byproduct phosphogypsum as a raw material, so the waste is turned into the wealth. The gypsum-based fireproof door core plate has the characteristics of good stability, high fire resistance, no corrosion to steel plates and high production efficiency, and effectively overcomes the defects of moisture absorption and low production efficiency of existing magnesite materials.
本发明提供一种石膏基防火门芯板，其特征在于，所述材料由包括如下重量份的原料组成：磷石膏基α高强石膏400‑500份，纤维0.1‑1.5份，发泡剂5‑8份，表面活性剂1‑2份，乳液5‑10份，PVA 0.5‑1份，水180‑250份。本发明制备的防火门芯板，干密度在280‑400kg/m3，采用得a型高强石膏以工业副产物磷石膏为原料，变废为宝。具有稳定性好、耐火性高、不腐蚀钢板、生产效率高的特点，有效的解决了现有菱镁材料吸湿，且生产效率较低的缺点。
