Building material applied to three-dimensional printing technology

Abstract

The invention discloses a building material applied to a three-dimensional printing technology. The building material is prepared from the raw materials in parts by weight: 60 to 70 parts of cement, 40 to 50 parts of industrial sludge, 30 to 40 parts of ceramic waste, 10 to 20 parts of kaolin compound, 30 to 40 parts of filler, 6 to 12 parts of magnesium oxide, 2 to 4 parts of aluminum sulfate, 1.5 to 2.5 parts of sodium phosphate, 15 to 25 parts of binder, 1 to 2 parts of water reducing agent and 60 to 80 parts of water. The kaolin compound is prepared by the following technology: mixing lauryl sodium sulfate, ammonium acetate, kaolin, water and manitol; warming; stirring; dropwise adding into normal hexane in a stirring state; adding tetrachloro-silicane and tetraethyl orthosilicate after dropwise adding; stirring; washing by normal hexane; vacuum freeze-drying to obtain the kaolin compound.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a building material used in the three-dimensional printing technology. Background technique [0002] Three-dimensional printing technology, also known as 3D printing technology, is a rapid prototyping technology. It is a technology that uses materials to construct objects by layer-by-layer printing based on digital model files. [0003] In the field of construction, due to the emergence of 3D printing technology, printing building materials into buildings has become a direction of rapid construction, and the most important thing is building materials. At present, general building materials cannot be used as 3D printing materials, and their functions are relatively single. They are easy to break, poor in thermal stability, and high in cost, which is not conducive to the needs of modern buildings. Contents of the invention [0004] Based on the technical prob...
