3D printing based cement based inorganic gelling material and preparation method thereof

Abstract

The invention provides a 3D printing based cement based inorganic gelling material and a preparation method thereof, and relates to a 3D printing material. In order to solve the problems of poorer printing precision and high-precision building component printing incapability of the existing gelling material for printing, the invention provides the 3D printing based cement based inorganic gelling material with the following technical scheme that the 3D printing based cement based inorganic gelling material is prepared from the following ingredients of cement, compaction filling materials, active mixing materials, water reducing agents, earth strength agents, accelerators, retarders, thickening water preservation agents, bonding agents, expansion agents, anti-foaming agents, anti-seepage agents, lubricating agents and fiber. The 3D printing based cement based inorganic gelling material has the beneficial effects that the preparation is simple and convenient; good continuous extrusion performance is realized; good overlapped layer building performance is realized; excellent waterproof, anti-seepage function and good anti-cracking performance are realized.

Description

technical field [0001] The invention relates to a 3D printing material, specifically, a cement-based inorganic gelling material based on 3D printing and a preparation method thereof. Background technique [0002] 3D printing is a technology of manufacturing three-dimensional products by adding materials layer by layer through 3D printing equipment based on the designed 3D model. This layer-by-layer accumulation forming technology is also called additive manufacturing. 3D printing integrates cutting-edge technologies in many fields such as digital modeling technology, electromechanical control technology, information technology, material science and chemistry. It is a kind of rapid prototyping technology and is known as the core technology of the "third industrial revolution". Compared with traditional manufacturing technology, 3D printing does not need to make molds in advance, remove a large amount of material during the manufacturing process, and get the final product with...

AI Technical Summary

Problems solved by technology

[0005] The existing gelling materials for printing have a long or too short bonding time, and the setting time cannot be freely adjusted to meet the requirements of printing and curing laminates, or they are solidified at the extrusion head during the printing process and cause blockage; The fluidity of gelled materials is not coordinated with extrusion printing, too large or too small will cause varying degrees of obstacles to extrusion printing; the existing gelled materials for printing cannot obtain early strength in a short period of time during the printing process, and it is difficult to guarantee printing The continuation of the process; the printing accuracy of the existing printing gel materials is poor, and it is impossible to print high-precision building components
