High-strength environment-friendly gypsum plaster board and preparation method thereof
The invention discloses a high-strength environment-friendly gypsum plaster board and a preparation method thereof. The preparation method of the gypsum plaster board comprises the following steps: step 1, dissolving alum, a gel material and a foaming agent in deionized water to obtain a raw material A; uniformly mixing phosphogypsum, calcium carbonate, an adhesive and a water reducing agent to obtain a raw material B; adding the raw material B into the raw material A, and uniformly mixing to obtain a gypsum core layer material; step 2, respectively placing surface paper and bottom paper in the impregnation liquid, and carrying out impregnation treatment to obtain surface paper A and bottom paper A; 3, under the mold, the gypsum core layer material is poured on the bottom paper A, and the surface paper A is laid on the surface of the bottom paper A; after the wet plate is solidified, drying and forming; performing ultraviolet curing and high-temperature drying to constant weight to obtain the gypsum plaster board. According to the technical scheme, the gel material which is light, porous and good in heat insulation and sound insulation is prepared; and the light click reaction is utilized to inhibit the problems of viscosity reduction, strength reduction and the like caused by the addition of the gel material.
本发明公开了一种高强度环保纸面石膏板及其制备方法。所述纸面石膏板的制备包括以下步骤：步骤1：将明矾、凝胶材料、发泡剂溶解在去离子水中，得到原料A；将磷石膏、碳酸钙、粘胶剂、减水剂混合均匀，得到原料B；将原料B加入至原料A中混合均匀，得到石膏芯层料；步骤2：将面纸、底纸分别置于浸渍液中，浸渍处理，得到面纸A、底纸A；步骤3：在模具下，将石膏芯层料浇筑在底纸A上，并在其表面铺上面纸A；待湿板凝固后，干燥成型；紫外固化，高温烘干至恒重，得到纸面石膏板。本技术方案中，制备了一种轻质、多孔、隔热、隔音性好的凝胶材料；利用光点击反应，抑制因凝胶材料加入产生的粘性下降、强度下降等问题。
