技术领域
本发明涉及建筑材料领域，具体属于一种屋顶用防漏水泥石膏板。
背景技术
石膏板为建筑用普通材料，属于建筑施工中的必备材料。石膏板已广泛用于住宅、办公楼、商店、旅馆和工业厂房等各种建筑物的内隔墙、墙体覆面板（代替墙面抹灰层）、天花板、吸音板、地面基层板和各种装饰板等。市场上出现的防水石膏板容易出现裂纹的缺陷，不仅影响美观，也达不到防漏的效果。
发明内容
本发明的目的是提供一种屋顶用防漏水泥石膏板，有效利用磷石膏、矿渣微粉，结合性能好，而且具有良好的防漏水、耐酸碱，制作成本低，效果好。
本发明的技术方案如下：
一种屋顶用防漏水泥石膏板，由以下重量份计的下述组分组成：碎石土 10-14份、水泥55-60份、磷石膏8-10份、矿渣微粉2-4份、锯末屑3-5份、氧化石蜡皂2-3份、玻璃碎渣5-8份、硅酸铝纤维4-6份、钠基膨润土5-7份、乙酸钠 0.2-0.4份、防水剂4-6份、铝酸盐0.5-0.8份、水适量；其制备方法包括如下步骤：
（1）将碎石土、水泥、磷石膏、矿渣微粉、钠基膨润土和适量的水按比例混合，放入搅拌机中搅拌直至混合均匀；向搅拌机中加入乙酸钠、铝酸盐继续搅拌10-20min，得到混合浆料；
（2）将锯末屑、氧化石蜡皂、玻璃碎渣、硅酸铝纤维送入烘箱中加热到200-300℃，保温2-3h后自然冷却，待冷却后得到保温添加料，将保温添加料在标准养护箱中养护 1-2天，备用；
（3）将上述步骤（1）、（2）中得到的产物与其他剩余组分混合，浇筑入模成型，后在 45-55℃下预养 2-4h，脱模，吊运至切割部切割，得石膏板坯件；
（4） 将步骤（3）中的石膏板坯件放入反应釜中蒸压养护3-4h，蒸汽压力保持0.38 MPa～0.7MPa的压力，即得入库成品。
一种屋顶用防漏水泥石膏板，由以下重量份计的下述组分组成：碎石土 12份、水泥58份、磷石膏9份、矿渣微粉3份、锯末屑4份、氧化石蜡皂2.5份、玻璃碎渣7份、硅酸铝纤维5份、钠基膨润土6份、乙酸钠 0.3份、防水剂5份、铝酸盐0.6份、水适量。
本发明在原材料中参用了磷石膏、矿渣微粉，在石膏板的表面形成致密的防水层，结合性能好，而且具有良好的防漏水、耐酸碱，制作成本低，效果好。
具体实施方式
一种屋顶用防漏水泥石膏板，由以下重量份计的下述组分组成：碎石土 12份、水泥58份、磷石膏9份、矿渣微粉3份、锯末屑4份、氧化石蜡皂2.5份、玻璃碎渣7份、硅酸铝纤维5份、钠基膨润土6份、乙酸钠 0.3份、防水剂5份、铝酸盐0.6份、水适量；其制备方法包括如下步骤：
（1）将碎石土、水泥、磷石膏、矿渣微粉、钠基膨润土和适量的水按比例混合，放入搅拌机中搅拌直至混合均匀；向搅拌机中加入乙酸钠、铝酸盐继续搅拌15min，得到混合浆料；
（2）将锯末屑、氧化石蜡皂、玻璃碎渣、硅酸铝纤维送入烘箱中加热到250℃，保温2.5h后自然冷却，待冷却后得到保温添加料，将保温添加料在标准养护箱中养护 1.5天，备用；
（3）将上述步骤（1）、（2）中得到的产物与其他剩余组分混合，浇筑入模成型，后在 50℃下预养3h，脱模，吊运至切割部切割，得石膏板坯件；
（4） 将步骤（3）中的石膏板坯件放入反应釜中蒸压养护3.5h，蒸汽压力保持0.56MPa的压力，即得入库成品。
本发明具体实施方式制得的石膏板性能参数如下：
