White high-performance cement-based 3D printing material and preparation method thereof
The invention discloses a white high-performance cement-based 3D printing material and a preparation method thereof. Comprising 100 parts by weight of C50 white Portland cement, 40 to 50 parts by weight of white calcium carbonate, 180 to 200 parts by weight of white quartz sand, 25 to 30 parts by weight of water, 2 to 4 parts by weight of polyvinyl alcohol fiber, 0.5 to 1.2 parts by weight of a super plasticizer, 0.1 to 0.15 part by weight of hydroxypropyl methyl cellulose and 1 to 3 parts by weight of white nanoscale SiO2. The problems that an existing 3D printing concrete member is subjected to natural weathering, paint surface stripping and damage are fast, and attractiveness is easily lost are solved.
本发明公开了一种白色高性能水泥基3D打印材料及其制备方法，包括100重量份的C50白色硅酸盐水泥、40～50重量份的白色碳酸钙、180～200重量份的白色石英砂、25～30重量份的水、2～4重量份的聚乙烯醇纤维、0.5～1.2重量份的超塑化剂、0.1～0.15重量份的羟丙基甲基纤维素、1～3重量份的白色纳米级SiO2。本发明解决了现有的3D打印混凝土构件受到自然风化作用，漆面剥脱损毁快，极易丧失美观性的问题。
