Lightweight gypsum board
The invention discloses a lightweight gypsum board and belongs to the technical field of building materials. The lightweight gypsum board comprises a gypsum board core formed between two parallel covering materials, the gypsum board core is made of gypsum-containing slurry, and the gypsum-containing slurry comprises water, building gypsum powder, native starch, sodium sulfosuccinate, sodium alkyl benzene sulfonate, sodium trimetaphosphate and glass fibers; and the volume content of gaps in a range of 1-5 microns in the gypsum board core is controlled to be less than 8% of the total volume of the gaps. Sodium trimetaphosphate is a conventional additive in the field of gypsum boards, and can enhance the strength, permanent deformation resistance, dimensional stability and other properties of gypsum green bodies. The glass fiber is also a conventional reinforcing material in the field of gypsum boards, and can improve the strength of the gypsum board and improve the bonding force in the gypsum board core. A facing material may be formed from any suitable material, including but not limited to facing paper, plastic wallpaper, aluminum foil, fibrous mats, and the like.
一种轻质石膏板，属于建筑材料技术领域。所述轻质石膏板包括在两个平行的护面材料之间形成的一个石膏板芯，该石膏板芯由含石膏的浆料制成，所述含石膏的浆料包括：水、建筑石膏粉、原淀粉、琥珀酸酯磺酸钠、烷基苯磺酸钠、三偏磷酸钠、玻璃纤维；所述石膏板芯中1‑5微米范围内空隙的体积含量控制在总空隙体积的8％以下。三偏磷酸钠为石膏板材领域常规的添加剂，可以增强石膏生坯的强度、抗永久变形性、尺寸稳定性等性能。玻璃纤维也为石膏板材领域常规的增强材料，可以提高石膏板的强度，改善石膏板芯内部的粘接力。护面材料可以由任何合适的材料形成，包括但不限于由护面纸、塑料壁纸、铝箔、纤维垫等形成。
