Ultra-high performance additive manufacturing dry powder, preparation method, printed base material and method
The invention relates to a preparation method of ultra-high-performance dry powder for additive manufacturing, which comprises the following steps: providing nano-scale silica gel and micron-scale inert filler, and uniformly mixing to form a first batch of premix; the first batch of premix is dried; a second batch of premix is added into the dried first batch of premix and evenly mixed, the additive manufacturing dry powder with printability in both rheological characteristics and setting time is obtained, and the second batch of premix comprises PO425 cement, CSA cement, a super plasticizer and hydroxypropyl methyl cellulose. The problem that a traditional 3D printing cement-based material is insufficient in strength is solved.
本发明涉及一种超高性能增材制造干粉料的制备方法，包括步骤：提供纳米级硅凝胶和微米级惰性填料并混合均匀，形成第一批预混料；对该第一批预混料进行烘干；向烘干后的第一批预混料中加入第二批预混料并混合均匀，以得到流变学特性和凝结时间均具备可打印性的增材制造干粉料，该第二批预混料包括PO425水泥、CSA水泥、超塑化剂和羟丙基甲基纤维素。本发明解决了传统3D打印水泥基材料强度不够的问题。
