Problems solved by technology

[0003] Due to the characteristics of the building itself, the building has specific requirements for the construction performance, mechanical properties, functionality, durability and economy of the materials used during the printing and manufacturing process and after the building is completed. As far as the current situation is concerned, cement Concrete is still the first choice for building buildings, but because the printed building adopts the construction method of no formwork, extrusion and overlay molding, higher requirements are placed on the performance of building materials, and traditional cement concrete is not suitable for 3D printing buildings.

Abstract

The invention discloses a retarded pumping aid for 3D printing house slurry. The retarded pumping aid is prepared from, by weight, 10-18 parts of water reducing agent, 10-15 parts of retarder, 7-11 parts of lubricant, 1-2 parts of air entraining agent, 0.1-0.3 part of 3-[(2,4-dichloro)phenyl]-2-acrylic acid, 0.01-0.02 part of ammonium sulfate, 0.05-0.07 part of syrup, 0.01-0.03 part of humic acid, 0.03-0.07 part of additive and 0.01-0.02 part of honey. According to the retarded pumping aid for the 3D printing house slurry, the slurry opening time can be prolonged, the slurry workability can be improved, the pumpability is improved, and meanwhile good flowability can be kept for a long time. The properties such as coagulability, pumpability and mechanical strength of 3D printing house building materials are achieved simultaneously; by means of the retarded pumping aid for the 3D printing house slurry, the compactibility, durability and anti-permeability of the 3D printing house slurry can be effectively improved.

Description

technical field [0001] The invention relates to a pumping agent for slurry, in particular to a retarding pumping agent for 3D printing house slurry. Background technique [0002] 3D printing technology is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. Now, 3D printing technology has begun to try to be used in the construction of houses. Compared with traditional building technology, the advantages of 3D printing building technology are reflected in: fast speed - more than 10 times faster than traditional building technology; complex and diverse buildings that are difficult to build in traditional ways can be produced without using templates, reducing Construction costs; no need for a large number of construction workers, reducing safety risks during construction; and reducing waste by-products, can effectively use building materials, greatly reduce the demand for cemen...
