[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 super plasticizer for three-dimensional printing house slurry. The super plasticizer is prepared from the following component raw materials in parts by weight: 10 to 30 parts of sodium lignosulphonate, 10 to 15 parts of a lubricating agent, 1 to 2 parts of sodium sulfate, 0.1 to 0.3 part of 3-[(2,4-dichloro)phenyl]-2-crylic acid, 0.01 to 0.03 part of ammonium chloride, 0.01 to 0.03 part of ammonium dihydrogen phosphate, 0.5 to 2.5 parts of additives and 0.001 to 0.002 part of pentadecyl phenol. The super plasticizer for the three-dimensional printing house slurry, disclosed by the invention, is good in water-reducing property, and the water-reducing rate reaches 15 percent to 35 percent; furthermore, the durability properties, such as anti-permeability, anti-freezing and anti-carbonization properties, of a product are obviously improved, and the compactibility, durability and anti-permeability of the three-dimensional printing house slurry can be improved; and meanwhile, the mixability of the slurry is obviously improved.
Description
technical field [0001] The invention relates to a superplasticizer for slurry, in particular to a superplasticizer 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 cement, a...
