Abstract

The invention discloses a coagulation-accelerating early strength agent for 3D printing house slurry. The coagulation-accelerating early strength agent is prepared from raw materials in parts by weight as follows: 50-100 parts of anhydrous sodium sulfate, 1-7 parts of calcium nitrite, 5-7 parts of aluminum sulfate, 5-10 parts of humic acid, 0.1-0.3 parts of guar gum, 5-7 parts of 3-[(2,4-dichloro)phenyl]-2-propenoic acid, 10-20 parts of a filling agent and 1-3 parts of additives. The coagulation-accelerating early strength agent is exclusively used for a 3D printing house and can promote coagulation and hardening of the 3D printing house slurry, and the strength of the slurry after coagulation develops more rapidly than that of a conventional early strength agent; furthermore, the cost of the raw materials of coagulation-accelerating early strength agent is low, and the applicability is wider.

Description

technical field [0001] The invention relates to a coagulation accelerator, in particular to a coagulation accelerator 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...
