Description

一种泡沫混凝土材料的制备方法
技术领域
本发明涉及一种泡沫混凝土材料的制备方法，属于材料技术领域。
背景技术
市场上的建筑材料有金属压延夹芯板、水泥聚苯乙烯泡沫保温板、泡沫混凝土砌块等，其中：金属压延夹芯板用于活动板房，将金属薄板喷漆压延做面层，中间用聚苯乙烯泡沫板做保温隔声垫层，其缺点为易燃烧、易生锈；水泥聚苯乙烯泡沫保温板采用聚苯乙烯泡沫加工成颗粒与水泥、黄泥、粉煤灰搅匀入模夯实码架养护，全部人工操作，产品强度低，表面粗糙，尺寸差别大，仅用于屋面保温垫层；泡沫混凝土砌块采用铝粉做发泡剂，将水泥、硅粉、石灰石粉、粉煤灰加入搅匀，放入大容量箱静态反应，初凝后切割成所需大小码垛蒸养，其缺点为设备投资大、能耗高、产品吸水率高、抗冲击性能差、易干缩开裂、受区域限制。
发明内容
本发明通过采用新配方，制备的材料能解决上述问题。
本发明提供了一种泡沫混凝土材料的制备方法，所述材料的原料，按重量份，由下述组分组成：
本发明所述材料的原料优选为，按重量份，由下述组分组成：
本发明所述制备方法优选为包括如下步骤：
①按重量份，将水泥、硅粉、钙粉与石膏粉混匀；
②按重量份，先将聚苯乙烯泡沫颗粒与河沙混匀，再加入步骤①所得产品混匀，然后加水混匀，所述加水量为原料重量的15～20％，入模、成型、脱模、自然养护或蒸养。
本发明有益效果为：
①本发明制备的材料的导热系数为0.08W/(m.K)，与国标0.24W/(m.K)比，提高3倍；
②本发明制备的材料吸水率低，其凹凸的表面，使饰面层不易剥离分层；
③本发明制备的材料为实心质轻材料，隔音效果好；
④本发明制备的材料为柔性防震材料；
⑤本发明制备的材料因高频振压将泡沫封闭包裹，使其不易燃烧。
