Description

一种3D打印用保温砂浆的制备方法
技术领域
本发明涉及3D打印技术领域,尤其涉及一种3D打印用保温砂浆的制备方法。
背景技术
由于3D打印技术不同于传统的施工方式,与传统水泥混凝土相比,对3D打印混凝土提出了更高、更全面地要求,性能也发生了巨大变化,因此为适应3D打印技术在建筑中的应用,首要解决的问题是制备出符合3D打印建筑技术需要的具有良好保温效果与韧性的打印水泥基材料。
发明内容
基于背景技术存在的技术问题,本发明提出了一种3D打印用保温砂浆的制备方法,耐水性好,导热系数小,保温效果好,而且强度高,降低脆性。
本发明提出的一种3D打印用保温砂浆的制备方法,其原料按重量份包括:磷酸镁水泥50-80份,硅酸盐水泥18-29份,海泡石粉0.5-1.2份,砭石粉35-45份,沸石粉10-18份,亚麻纤维20-40份,碳纤维1.5-3.5份,引气剂0.6-1.5份,减水剂0.2-1份,海藻酸钠0.4-1份,滑石粉5-10份,水40-50份。
优选地,磷酸镁水泥、硅酸盐水泥的重量比为60-70:20-24。
优选地,海泡石粉、砭石粉、沸石粉、亚麻纤维的重量比为0.5-1:38-40:12-14:26-30。
优选地,碳纤维、磷酸镁水泥、硅酸盐水泥的重量比为3-3.2:60-70:20-24。
优选地,碳纤维、亚麻纤维的重量比为3-3.2:26-30。
本发明采用磷酸镁水泥、硅酸盐水泥复配为凝胶材料,一方面可避免磷酸镁水泥耐水性差的问题,另一方面导热系数小,保温效果好,加入的碳纤维均匀分布在砂浆内,容易与磷酸镁水泥、硅酸盐水泥分散粘结,提高砂浆的强度,降低脆性;而碳纤维可促使海泡石粉、砭石粉、沸石粉、亚麻纤维在体系中分散,可减缓热量传递,并可避免物料密度不同导致分布不均的现象,从而增强成型后的韧性,提高材料的抗热冲击性,降低建筑能耗;加入砭石粉、沸石粉、亚麻纤维可有效调节材料的粘度为处于0.5-1Pa·s范围,便于3D打印过程的进行,且混凝土材料的导热系数为0.6-0.8W/m·K,在保温方面远优于单一的混凝土和砂浆。
