3D (three-dimensional) Printing method of building structural wall

Abstract

The invention discloses a 3D (three-dimensional) printing method of a building structural wall, comprising the steps of mixing waste concrete powder and waste brick powder, crushing, grinding, drying,adding cement, and mixing well to obtain a first material; mixing carbon nanotubes, castor oil and water, heating, stirring, drying by spraying, adding formic acid and petroleum ester, mixing well, adjusting temperature for stirring, dropwise adding phosphoric acid solution, continuing to perform stirring, dropwise adding hydrogen peroxide, stirring, filtering, drying, adding a water reducer, iron tailings, nano zirconia, gypsum, iolite and nano spherical iron oxide magnet powder, and mixing well to obtain a second material; adding, continuing to perform stirring while adding the first material, the second material and bismaleimide, continuing to perform stirring until a viscous slurry is obtained, transferring the slurry to a 3D printing system, and performing printing to obtain the building structural wall.

Description

Technical field

[0001] The invention relates to the technical field of 3D printing, in particular to a method for 3D printing architectural structure walls. Background technique

[0002] Since its inception, 3D printing technology has rapidly changed the production process of many industries and achieved production effects that are difficult to achieve with traditional processes. 3D printing technology can make the cost of a single product independent of its production quantity, and can carry out the personalized and customized production of the product, so as to reach the advanced level of manufacturing.

[0003] At present, the advantages of 3D printing technology are concentrated in the field of industrial design, and the advantages in the field of building materials are becoming more and more obvious. 3D printers use building materials as raw materials and adopt digital modeling and layer-by-layer printing methods to meet various conventional or special-shaped buildings.
