Description
技术领域
本发明属于建筑板材技术领域,具体涉及一种粉煤灰轻质隔墙板及其制备方法。
背景技术
目前建筑行业,ALC板材很受宠爱。ALC是(Autoclaced Lightweight Concrete)的缩写,中文名称为蒸压轻质加气混凝土。是以硅砂、水泥、生石灰、石膏为原料,用铝粉为发泡剂,经一系列工艺过程(配料、配筋、发泡、切割)最后经高温、高压蒸汽养护获得的多孔硅酸盐制品。其实不管是ALC板还是AAC板还是NALC板都是蒸压加气混凝土板的简称。
但是该板材在制备过程中,需要用到水泥、钢筋等材料,增加了成本及重量,而且制备工艺中需要发泡蒸压的工艺,增加了成本及风险。
发明内容
本发明针对现有建筑板材成本高、质量重及制备工艺复杂的问题,提供一种粉煤灰轻质隔墙板及其制备方法。
本发明采用如下技术方案:
一种粉煤灰轻质隔墙板,包括两层玻璃纤维网格布和位于玻璃纤维网格布之间的基材,所述基材包括如下质量份数的组分:粉煤灰45~55%,珍珠岩20~30%,粘合剂15~25%,锯末3~8%;其中粘合剂包括氯化镁水溶液和氧化镁,质量比为1:0.9~1.3;所述氯化镁水溶液的波美度为23~25°。
优选地,一种粉煤灰轻质隔墙板,包括两层玻璃纤维网格布和位于玻璃纤维网格布之间的基材,所述基材包括如下质量份数的组分:粉煤灰50%,珍珠岩25%,粘合剂20%,锯末5%。
一种粉煤灰轻质隔墙板的制备方法,包括如下步骤:
第一步,根据生产要求布置模具,涂抹脱模剂,在模具底部铺设一层玻璃纤维网格布;
第二步,按比例称取基材各组份,搅拌均匀;
第三步,将基材倒入模具内,并均匀抹平;
第四步,在基材顶部铺设一层玻璃纤维网格布,挤压成型,即可得粉煤灰轻质隔墙板。
本发明的有益效果如下:
1. 本发明的板材没有用到钢筋和水泥,只用粉煤灰和锯末废料为主料,既减轻了质量又节省了成本,便于搬运、便于操作施工。
2. 本发明的制备工艺无须发泡蒸压的工艺,只需挤压成型,制备方法成本低,安全性高。
3. 本发明的板材在减少了材料的基础上,力学性能又没有损失,具有良好的力学性能和隔热保温性能。
