Description
技术领域
本发明属于新型节能建筑材料技术领域,尤其涉及一种泡沫自保温复合砌块及其制备方法。
背景技术
泡沫自保温复合砌块是建筑墙体材料的发展趋势,它要求这一新型墙体材料要具备轻质防水、保温隔热、隔音防火等诸多复合特点,特别是建筑节能要求要达到65%以上。现有的保温隔热材料存在以下缺点:(1)有机物不阻燃,达不到防火要求;(2)材料过重,造成梁柱承载加大,增加了建筑造价,同时增加了建筑工人的劳动强度;(3)生产工艺复杂,产能低下,劳动生产率不高。
发明内容
本发明要解决的技术问题是提供一种泡沫自保温复合砌块及其制备方法,该泡沫自保温复合砌块除了克服上述问题之外,最大的特点是大量使用了工业固废物(灰渣)及建筑垃圾,减少了水泥的使用量,达到了废物利用,循环使用,节能降耗,降低生产成本的目的。
本发明砌块由以下质量份数的原料制备而成:
水泥8-15%、矿粉20-28%、粉煤灰15-20%、镍渣30-40%、泡沫剂0.5-0.8%、胶凝材料改性剂0.3-0.6%、增强剂0.4-0.7%、促凝剂0.2-0.6%和水18-25%。
进一步地,所述砌块由以下质量份数的原料制备而成:
水泥12%、矿粉24%、粉煤灰17%、镍渣35%、泡沫剂0.6%、胶凝材料改性剂0.5%、增强剂0.6%、促凝剂0.4%和水22%。
相应的,所述砌块的制备方法包括以下步骤:
1)进料:称取原料,按质量分数比称取水泥、矿粉、粉煤灰和镍渣共400kg,混合均匀,加入到搅拌机中,加入200kg的常温水,搅拌均匀;
2)添加辅料:称取辅料,按质量分数比称取胶凝材料改性剂、增强剂和促凝剂共2.5kg,加入到步骤1)中;
3)发泡:称取0.6kg泡沫剂进行发泡,将发泡后的泡沫剂添加至步骤2)中,搅拌4-6min;
4)注模和初养;
5)切割和码垛;
6)静养;
7)出厂。
与现有技术相比,本发明具有如下技术优势:
(1)充分利用和挖掘工业固废物特点,主材几乎不占用工业产成品和自然资源,对保护环境意义重大,属环境友好型产业。
(2)作为新型墙体材料,具有多重复合性能,不限于其中单一特点,不需再做保温防火处理。
(3)生产过程单一成型,自动化、机械化程度高,大大提高了劳动生产率,减轻了工人劳动强度,改善了工作环境,适应了现代化大工业的发展趋势。
(4)由于大量使用了工业和建筑废弃物,大大降低了生产成本,不仅经济效益显著,而且有良好的社会效益和环境效益。
(5)由于其轻质大砌块的特点,大大提高了建筑工人的建筑效率,同时在一定程度上解决了建筑业长期存在的“肥梁胖柱深基础”这一痼疾,对降低建筑物造价也作用明显。
