Anti-compression 3D printing building material

Abstract

The invention discloses an anti-compression 3D printing building material. The anti-compression 3D printing building material comprises, by weight, 25 to 45 parts of a graphite compound, 35 to 45 parts of paper mill sludge, 20 to 40 parts of foundation soil, 50 to 60 parts of mine tailing, 100 to 110 parts f a filling material, 3 to 5 parts of condensated sodium silicate, 1 to 2 parts of fatty alcohol polyoxyethylene ether, 2 to 4 parts of sodium oleate, 2 to 4 parts of copper sulphate, 2 to 4 parts of aluminum sulfate, 2 to 4 parts of sodium chloride, 2 to 4 parts of silver nitrate, and 40 to60 parts of water. The graphite compound is prepared from following steps: polyethylene wax, graphite powder, dibutyltin dilaurate, and toluene diisocyanate are mixed, an obtained mixture is heated and stirred, epoxy soybean oil is added for uniform mixing, phthalic anhydride and N,N-dimethylbenzylamine are added for mixing, an obtained mixed material is heated, stirred, filtered, and smashed, ammoniacal liquor and absolute ethyl alcohol are added for uniform mixing, ethyl orthosilicate is added for stirring, an obtained product is added into liquid paraffin at stirring states drop by drop, and cooling, separating, and washing are carried out so as to obtain the graphite compound.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a pressure-resistant 3D printing building material, Background technique [0002] 3D printing technology is a new type of material preparation technology that has received widespread attention and rapid development in the past 30 years. It is based on digital models and constructs objects by layer-by-layer printing. "Vital Production Tools of the Third Industrial Revolution". [0003] 3D printing building materials is a new technology applied to building wall construction based on 3D printing technology.
